Why GAO Did This Study: 

Medicare Advantage (MA) plans are an alternative to the original 
Medicare fee-for-service (FFS) program. Private fee-for-service (PFFS) 
plans—one type of MA plan—give beneficiaries an option that is more 
like Medicare FFS than other MA plans, with a wider choice of providers 
and less plan management of services and providers. PFFS enrollment 
increased from about 35,000 beneficiaries in June 2004 to about 2.3 
million in June 2008. This report compares PFFS plans to other MA plans 
and Medicare FFS in three areas: (1) characteristics of beneficiaries, 
(2) financial risks for beneficiaries who do not contact their plans 
before receiving services, and (3) disenrollment rates. To do this 
work, GAO reviewed materials from a selected sample of nine PFFS plan 
sponsors, analyzed Medicare data, and interviewed officials from CMS, 
which administers the Medicare program, and other organizations. 

What GAO Found: 

In April 2007, beneficiaries in PFFS plans tended to be healthier and 
generally younger than beneficiaries in other MA plans and Medicare 
FFS. Specifically, projected health care expenditures for PFFS 
beneficiaries were 7 percent less than the projected average for 
beneficiaries in other MA plans and 10 percent less than the projected 
average for beneficiaries in Medicare FFS. Beneficiaries in PFFS plans 
also generally were more likely than beneficiaries in other MA plans 
and Medicare FFS to reside in rural areas where fewer other MA plans 
were available. In addition, about 81 percent of beneficiaries who were 
new enrollees in PFFS plans were in Medicare FFS before enrolling in 
their plan, compared to 65 percent in other MA plans. 

PFFS beneficiaries may have faced certain financial risks if they did 
not contact their plan before receiving services. These risks were 
generally not assumed by beneficiaries in other MA plans and Medicare 
FFS. Specifically, if beneficiaries or their providers did not contact 
their PFFS plans before obtaining a service to make sure it would be 
covered, beneficiaries unexpectedly may have had to pay for the entire 
cost of the service if coverage was later denied by their plan. CMS 
officials told GAO they did not have data on the extent to which PFFS 
beneficiaries were faced with such costs. Furthermore, some 
beneficiaries likely experienced higher out-of-pocket costs for covered 
services if they did not contact their plan before obtaining the 
services. For example, one sponsor of PFFS plans increased the share of 
the cost for which beneficiaries were responsible from 30 percent to 70 
percent if the beneficiaries did not contact the plan before obtaining 
certain durable equipment. GAO found that some PFFS plans were 
inappropriately using the term prior authorization, which can involve 
denying service coverage if prior plan approval is not obtained, in 
their informational materials. CMS officials stated that PFFS plans 
should not have used this term because these plans were not permitted 
to deny service coverage due to lack of prior plan approval. However, 
CMS guidance on this issue has been inconsistent and sometimes 
incorrect. 

From January through April 2007, beneficiaries in PFFS plans 
disenrolled at an average rate of 21 percent compared to 9 percent for 
other MA plans, and GAO concludes that CMS has not complied with 
statutory requirements to mail disenrollment rates to Medicare 
beneficiaries. Disenrollment rates can reflect factors such as 
beneficiary satisfaction and CMS is required by law to mail this 
information to Medicare beneficiaries to help them compare available MA 
plans in their area. Although CMS has not mailed disenrollment rates to 
beneficiaries since 2000, the agency did provide disenrollment rates 
through Medicare’s Web site. However, this information was based on 
disenrollment in 2004 and 2005 and, given the enrollment growth since 
then, may not accurately reflect plans available to beneficiaries in 
2008. 

What GAO Recommends: 

GAO recommends that CMS (1) investigate the extent to which PFFS 
beneficiaries face unexpected costs for not contacting their plan 
before receiving care, (2) ensure that CMS guidance on prior 
authorization reflects CMS policy, and (3) mail MA plan disenrollment 
rates to beneficiaries, as required by statute, and update rates on 
Medicare’s Web site. CMS outlined the steps it was taking to respond to 
all three recommendations, but did not address how it would distribute 
disenrollment rates.

Congressional Requesters: 

Medicare Advantage (MA) plans are an alternative to original Medicare 
fee-for-service (FFS) in which private plans provide Medicare benefits 
to enrolled beneficiaries.[Footnote 1] Enrollment in MA plans has grown 
substantially in recent years from about 4.7 million beneficiaries in 
June 2004 to 9.6 million--about 1 out of every 5 Medicare 
beneficiaries--as of June 2008. This increase in enrollment followed 
the enactment of the Medicare Prescription Drug, Improvement, and 
Modernization Act of 2003,[Footnote 2] which among other things, 
resulted in increased payments to MA plans. MA plans are able to use 
the increased payments to offer more benefits and reduce beneficiary 
cost sharing relative to Medicare FFS. In addition, the increased 
payments allowed MA plans to expand into geographic areas where 
previously plan options had been very limited, resulting in more plan 
choices for beneficiaries. 

Nearly half of the recent growth in MA enrollment, about 45 percent, 
occurred in one type of plan--private fee-for-service (PFFS) plans. 
[Footnote 3] Enrollment in these plans increased from about 35,000 
beneficiaries in June 2004 to about 2.3 million beneficiaries in June 
2008. About one-quarter of beneficiaries enrolled in MA plans in June 
2008 were enrolled in a PFFS plan, and 99 percent of Medicare 
beneficiaries in 2008 had access to a PFFS plan--up from 41 percent in 
2005. The Congressional Budget Office (CBO) projects continued growth 
in PFFS and other MA plans through 2013, though at a slower pace. 
[Footnote 4] 

The growth in enrollment and availability of MA plans has financial 
implications for the Medicare program because the program pays more for 
beneficiaries in these plans than it would if they were in Medicare 
FFS. The federal government is projected to spend about $91 billion on 
the MA program in 2008.[Footnote 5] According to the Medicare Payment 
Advisory Commission (MedPAC), in 2008, Medicare is projected to pay 
about 13 percent more for beneficiaries in MA plans overall and 17 
percent more for beneficiaries in PFFS plans than what the program 
would have paid for these beneficiaries under Medicare FFS.[Footnote 6] 

PFFS plans are designed to offer beneficiaries an MA option that is 
more like Medicare FFS. Compared to other MA plans, PFFS plans 
generally offer a wider choice of providers and impose less plan 
management of health care services and providers. Unlike other types of 
MA plans, such as Health Maintenance Organizations (HMO) and Preferred 
Provider Organizations (PPO),[Footnote 7] PFFS plans are not required 
to have networks of contracted providers if they pay providers Medicare 
FFS rates or higher.[Footnote 8] Further, providers can agree to accept 
a PFFS beneficiary on a service-by-service basis. Almost all PFFS plans 
operate without networks.[Footnote 9] Paying providers at Medicare FFS 
rates or higher suggests that beneficiaries in PFFS plans will have 
access to those providers who accept beneficiaries from Medicare's FFS 
program. However, there have been reports that, in some areas, it may 
be more difficult for beneficiaries to obtain care while in PFFS plans 
than it would be if they were in Medicare FFS.[Footnote 10] 

Under federal law, PFFS plans may not place providers at financial risk 
or restrict beneficiary access to providers.[Footnote 11] The Centers 
for Medicare & Medicaid Services (CMS), the agency that administers the 
Medicare program,[Footnote 12] prohibits PFFS plans--but not other 
types of MA plans--from requiring that providers or beneficiaries 
obtain plan approval before a service is furnished as a condition of 
coverage, a process known as prior authorization. However, sponsors of 
PFFS plans, like sponsors of other MA plans, must provide an advance 
coverage determination, should beneficiaries or their providers request 
one.[Footnote 13] An advance coverage determination informs 
beneficiaries before they receive services whether the services will be 
covered and the amount that the beneficiary must pay with respect to 
such services. In finalizing regulations in 1998 for the MA program 
(then called the Medicare+Choice program), CMS considered requiring 
PFFS plan sponsors to mandate that providers who serve PFFS plan 
beneficiaries assume the responsibility for acquiring advance coverage 
determinations or risk being unable to charge beneficiaries if the plan 
later denied payments for the services.[Footnote 14] CMS, however, 
determined that this beneficiary protection would be inconsistent with 
federal statutory provisions that prohibit PFFS plans from placing 
their providers at financial risk. 

The rapid growth in PFFS plan enrollment highlights the need for more 
information about who is enrolling in, and disenrolling from, these 
plans. Specifically, if healthier beneficiaries are enrolling and 
staying in PFFS plans, this could leave other MA plans or the Medicare 
FFS program with sicker and potentially more costly beneficiaries. 
Also, if PFFS plans have high disenrollment rates compared to other MA 
plans, this could be an indicator of beneficiary dissatisfaction with 
access or quality of care or could indicate that other plans with more 
attractive benefit packages are available. In order to help Medicare 
beneficiaries compare and select MA plans, CMS is required by law to 
mail certain information to beneficiaries annually, including MA plan 
disenrollment rates for the previous 2 years to the extent that these 
disenrollment rates are available.[Footnote 15] 

Certain features of PFFS plans will change as a result of the Medicare 
Improvements for Patients and Providers Act of 2008 (MIPPA).[Footnote 
16] Beginning in 2011, PFFS plans will be required to form contracted 
networks of providers in areas that have at least two available network-
based plans (such as HMOs or PPOs).[Footnote 17] In areas with fewer 
than two network-based plans, most PFFS plans will continue to have the 
option of operating without networks if they pay providers at Medicare 
FFS rates or higher.[Footnote 18] In addition, beginning in 2010, PFFS 
plan sponsors will be required to have quality improvement programs for 
each plan and report related quality information to CMS.[Footnote 19] 

Given the uniqueness of PFFS plans and their rapid enrollment growth, 
you asked us to examine the characteristics of beneficiaries in these 
plans, PFFS plan features, and beneficiary disenrollment patterns. Our 
report addresses the following objectives: (1) compare the 
characteristics of beneficiaries in PFFS plans to the characteristics 
of beneficiaries in other MA plans and Medicare FFS; (2) describe the 
financial risks that beneficiaries in PFFS plans face, compared to 
beneficiaries in other MA plans and Medicare FFS, if they do not 
contact their plan prior to receiving services; and (3) compare the 
rates at which beneficiaries in PFFS plans disenroll to the rates for 
other MA plans and evaluate whether CMS met statutory requirements to 
mail disenrollment rates to beneficiaries. 

To compare the characteristics of beneficiaries in PFFS plans, 
specifically age, gender, and residential location, to the 
characteristics of beneficiaries in other MA plans and Medicare FFS, we 
analyzed Medicare enrollment data for April 2007. We restricted our 
analysis to five types of MA plans that accounted for more than 99 
percent of the approximately 7.8 million beneficiaries in MA plans at 
that time--PFFS plans, HMOs, local PPOs, regional PPOs, and Provider- 
Sponsored Organizations (PSO). After excluding plans that restrict 
enrollment and certain beneficiaries from our analysis, we analyzed 
data as of April 2007 for about 5.8 million beneficiaries in 1,998 MA 
plans and about 31.7 million beneficiaries in Medicare FFS.[Footnote 
20] To compare the health status of PFFS and other Medicare 
beneficiaries, we obtained plan-level risk scores from CMS, which are 
based on projected health care expenditures of plan beneficiaries and 
provide an indicator of the health status of the plans' beneficiaries. 
We also examined the type of Medicare coverage that MA beneficiaries 
held previously. For this analysis, we identified beneficiaries who 
were new to an MA plan type in April 2007 and examined their Medicare 
coverage in December 2006. MA plans that beneficiaries selected for 
2007 generally took effect from January through April 2007. 

To describe the financial risks that beneficiaries in PFFS plans face, 
compared to beneficiaries in other MA plans and Medicare FFS, if they 
do not contact their plan prior to receiving services, we reviewed 
relevant laws, regulations, documentation from CMS, and materials from 
nine PFFS plan sponsors interviewed that accounted for about 81 percent 
of PFFS enrollment in July 2007.[Footnote 21] We reviewed 2008 plan 
benefit information provided to beneficiaries as well as provider terms 
and conditions of payment for 30 PFFS plans, accounting for more than 
half of each sponsor's total enrollment in PFFS plans. We reviewed 2008 
plan benefit information provided to beneficiaries for 33 HMO or PPO 
plans operated by the same nine plan sponsors, accounting for more than 
half of each sponsor's total enrollment in other MA plans. We also 
interviewed officials from CMS and the plan sponsors. Information 
gathered from our review of the benefit information provided to 
beneficiaries for PFFS and other MA plans may not be representative of, 
or generalizable to, other MA plans offered by these and other plan 
sponsors that were not in our sample. 

To compare the rates at which beneficiaries in PFFS plans disenroll to 
the rates for other MA plans, we used Medicare enrollment data for 
beneficiaries in PFFS and other MA plans in December 2006 and April 
2007 to identify beneficiaries whose disenrollment took effect from 
January through April 2007.[Footnote 22] We calculated disenrollment 
rates for each MA contract, which covered one or more MA plans of the 
same plan type.[Footnote 23] To compare the health status of 
disenrollees to beneficiaries overall in PFFS and other MA plans, we 
used risk scores for 2006 as a proxy for health status. To evaluate 
whether CMS met statutory requirements to mail disenrollment rates to 
beneficiaries, we interviewed CMS officials, analyzed relevant federal 
laws and regulations, and reviewed disenrollment information CMS 
provided to Medicare beneficiaries through, for example, Medicare 
Options Compare (MOC) on Medicare's Web site.[Footnote 24] MOC is a 
source of information through which beneficiaries can compare the 
quality, benefits, and premiums of MA plans. 

We conducted interviews with CMS officials on the reliability of the 
CMS data used in our analysis. We also reviewed data documentation and 
performed certain data checks to ensure the data were reasonable and 
consistent. We determined that the data were sufficiently reliable for 
our purposes. We conducted our work from July 2007 through October 2008 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives. See appendix I for more 
details on our scope and methodology. 

Results in Brief: 

Beneficiaries in PFFS plans in April 2007 tended to be healthier and 
generally younger than beneficiaries in other MA plans and Medicare 
FFS, and were more likely to reside in rural areas where fewer other MA 
plan options were available. Specifically, beneficiaries in PFFS plans 
had projected health care expenditures--an indicator of health status-
-that were 7 percent less than the average for beneficiaries in other 
MA plans and 10 percent less than the average for beneficiaries in 
Medicare FFS. Beneficiaries in PFFS plans were less likely to be age 85 
or older, and were more likely to reside in rural areas where, on 
average, beneficiaries had access to about 12 different PFFS plans but 
only about 4 other MA plans. In addition, about 81 percent of new 
enrollees in PFFS plans had been enrolled in Medicare FFS before 
enrolling in their plan, compared to about 65 percent of new enrollees 
in other MA plans. 

If beneficiaries in PFFS plans did not contact their plans before 
obtaining services, they may have faced certain financial risks. These 
risks were generally not assumed by beneficiaries in other MA plans and 
Medicare FFS. Specifically, if beneficiaries in PFFS plans or their 
providers did not request an advance coverage determination from their 
plan before obtaining a service to ensure the service would be covered, 
beneficiaries unexpectedly may have had to pay for the entire cost of 
the service if coverage was later denied. However, beneficiaries in 
other MA plans and Medicare FFS generally had certain protections from 
this financial risk. CMS officials told us that they thought it was 
rare for PFFS beneficiaries to face unexpected costs of denied claims, 
but the agency did not have data on the extent to which this occurred. 
In addition, even when plans covered certain services, some PFFS 
beneficiaries likely experienced higher cost sharing if they or their 
providers did not notify their plans before receiving these services-- 
a process called prenotification. For example, the coinsurance rate for 
certain durable medical equipment for one PFFS plan changed from 30 
percent to 70 percent if beneficiaries or their providers did not 
prenotify their plan. In contrast, the other MA plans we reviewed did 
not have prenotification requirements, and Medicare FFS also had no 
such requirements. Furthermore, some PFFS plans' inappropriate use of 
the term prior authorization in their informational materials to 
describe beneficiary responsibilities for contacting their plan before 
receiving services may have confused beneficiaries and providers. 
According to CMS officials, PFFS plans should not have used the term 
prior authorization because PFFS plans cannot deny service coverage for 
lack of prior approval. However, CMS has provided inconsistent and 
sometimes incorrect guidance related to prior authorization for PFFS 
plans. 

From January through April 2007, beneficiaries in PFFS plans 
disenrolled at an average rate of 21 percent compared to 9 percent for 
other MA plans, and we conclude that CMS did not comply with statutory 
requirements to mail information on MA plan disenrollment rates to 
beneficiaries. Beneficiaries who disenrolled from PFFS plans, on 
average, were sicker compared to all beneficiaries in PFFS plans, with 
projected health care expenditures that were about 6 percent higher 
than the average for all beneficiaries in these plans. The same pattern 
existed for other MA plans, though the difference was less pronounced. 
MA disenrollment rates varied depending on beneficiaries' age and 
location. For example, older beneficiaries in PFFS plans, such as those 
who were age 85 and older, disenrolled at higher rates, but this was 
not the case for other MA plans. PFFS beneficiaries in urban areas 
disenrolled at higher rates than beneficiaries in rural areas, while in 
other MA plans, beneficiaries in urban areas disenrolled at slightly 
lower rates. MA plan disenrollment rates can reflect differences across 
plans because of factors such as beneficiary satisfaction with care and 
out-of-pocket costs. CMS is required by law to mail disenrollment rates 
for the previous 2 years, to the extent available, to Medicare 
beneficiaries at least 15 days prior to each year's annual coordinated 
election period. CMS officials informed us that they had not mailed 
disenrollment rates to all Medicare beneficiaries since the fall of 
2000. As these disenrollment rates were available to CMS, we conclude 
that CMS has not complied with statutory requirements to mail Medicare 
beneficiaries disenrollment rates for MA plans in their areas. CMS 
provided information on disenrollment rates and reasons for 
disenrollment to beneficiaries through MOC as of August 2008, but this 
information was based on data for 2004 and 2005. 

We recommend that the Acting Administrator of CMS (1) investigate the 
extent to which beneficiaries in PFFS plans are faced with unexpected 
out-of-pocket costs due to the denial of coverage when they did not 
obtain an advance coverage determination from their plan; (2) ensure 
that CMS guidance on prior authorization accurately reflects CMS policy 
and that PFFS plan materials conform to CMS requirements; and (3) mail 
to Medicare beneficiaries MA plan disenrollment rates for the previous 
2 years for MA plans that are or will be available in their areas, as 
required by statute, and update disenrollment rates provided to 
Medicare beneficiaries through MOC. 

In commenting on a draft of this report, CMS described the steps it 
would take to address each of our three recommendations. In response to 
our recommendation that CMS investigate the extent to which 
beneficiaries in PFFS plans are faced with out-of-pocket costs due to 
the denial of coverage from their plan, CMS noted that it is examining 
coverage denials and complaints. In response to our recommendation that 
CMS correct its guidance related to prior authorization, CMS described 
several steps it has taken and plans to take, including issuing new 
guidance. In response to our recommendation that the agency mail 
disenrollment rates to beneficiaries and update the rates on its Web 
site, the agency commented that it had recently awarded a contract to 
obtain disenrollment rates and other performance metrics by late 2009. 
However, the agency did not indicate how it would provide disenrollment 
rate information to beneficiaries. We also obtained comments from 
representatives of America's Health Insurance Plans (AHIP), a national 
association that represents private health plans, who raised certain 
points they thought the report should have emphasized and made several 
other observations. 

Background: 

Medicare is the federal government's health insurance program that 
covers more than 44 million people age 65 and older and certain 
individuals who are disabled or have end-stage renal disease. Most 
Medicare beneficiaries can choose to receive covered services through 
Medicare FFS or through an MA plan if one is offered where they live. 
[Footnote 25] Beneficiaries in Medicare FFS and in MA plans, including 
PFFS plans, pay monthly premiums and are responsible for cost sharing, 
which can be in the form of coinsurance (a percentage payment for a 
given service that a beneficiary must pay), a copayment (a standard 
amount a beneficiary must pay for a medical service), or a deductible 
(the amount a beneficiary must pay before Medicare FFS or an MA plan 
begins to pay). MA plans operate under annual contracts between MA plan 
sponsors and CMS and provide Medicare benefits in exchange for a 
monthly payment from CMS for each beneficiary enrolled in the plan. 
[Footnote 26] 

Beneficiaries can disenroll from MA plans during the annual coordinated 
election period, from November 15 through December 31 of a given year 
by enrolling in another plan or in Medicare FFS. Changes made during 
the annual coordinated election period take effect on January 1 of the 
following year. Beneficiaries can also disenroll from MA plans once 
during the open enrollment period, from January 1 through March 31 of a 
given year.[Footnote 27] Changes made during this time period take 
effect on the first day of the month following the plan's receipt of 
the beneficiary's request. 

Beneficiaries in PFFS Plans Were Healthier and Younger Than 
Beneficiaries in Other MA Plans and Medicare FFS and Differed in Other 
Ways: 

Relative to beneficiaries in other MA plans and Medicare FFS in April 
2007, beneficiaries in PFFS plans were healthier, generally younger, 
and more likely to live in rural areas with fewer MA options. 
Specifically, beneficiaries in PFFS plans had projected health care 
expenditures--an indicator of health status--that were lower, on 
average, than those of beneficiaries in other MA plans and Medicare 
FFS. Beneficiaries in PFFS plans had projected health care expenditures 
that were 7 percent less than those of beneficiaries in other MA plans 
and 10 percent less than beneficiaries in Medicare FFS. 

Beneficiaries in PFFS plans were generally more likely to be younger 
and reside in rural areas than beneficiaries in other MA plans and 
Medicare FFS (see table 1). PFFS plans had a smaller percentage of 
beneficiaries age 85 or older compared to other MA plans and Medicare 
FFS. Approximately 14 percent of PFFS beneficiaries lived in rural 
areas compared to 1 percent of beneficiaries in other MA plans and 10 
percent of beneficiaries in Medicare FFS. Medicare beneficiaries in 
rural areas, on average, had access to about 12 different PFFS plan 
options, but only about 4 other MA plan options. In contrast, Medicare 
beneficiaries in urban areas had access to an average of about 13 PFFS 
plan options and about 12 other MA plan options. As a result, 
beneficiaries in rural areas might have been more likely to enroll in a 
PFFS plan because there were fewer other MA options available in those 
areas.

New enrollees in PFFS plans as of April 2007 were more likely than new 
enrollees in other MA plans to have been in Medicare FFS prior to 
enrollment but less likely to have been new to Medicare altogether or 
previously in a different type of plan. About 81 percent of new 
enrollees in PFFS plans were in Medicare FFS prior to joining their 
plan, compared to 65 percent of new enrollees in other MA plans (see 
table 2). About 6 percent of new PFFS enrollees were new Medicare 
beneficiaries prior to joining their plan, compared to about 13 percent 
of new enrollees in other MA plans. About 13 percent of new enrollees 
in PFFS plans were in a different type of plan before enrolling in 
their current plan, compared to 23 percent of new enrollees in other MA 
plans.

PFFS Beneficiaries May Have Faced Certain Financial Risks Generally Not 
Assumed by Beneficiaries in Other MA Plans and Medicare FFS: 

In contrast to most beneficiaries in other MA plans and Medicare FFS, 
beneficiaries in PFFS plans may have faced certain financial risks if 
they or their providers did not contact their plan before receiving 
services. Specifically, if PFFS beneficiaries or their providers did 
not obtain advance coverage determinations, which specified whether 
services would be covered and how much beneficiaries would have to pay, 
beneficiaries unexpectedly may have been responsible for the entire 
cost of the service if coverage was later denied by their PFFS plans as 
not medically necessary.[Footnote 28] In addition, even if PFFS plans 
covered the services as medically necessary, some PFFS beneficiaries 
may have experienced substantially higher cost sharing if they or their 
providers did not contact their plans before receiving certain 
services. PFFS plans sometimes used the term prior authorization 
inappropriately to describe beneficiary or provider responsibilities 
for contacting their plans. CMS officials stated that PFFS plans should 
not have used this term because PFFS plans are not permitted to deny 
coverage for services when prior plan approval was not obtained. 
However, CMS guidance for PFFS plans related to prior authorization has 
been inconsistent and sometimes incorrect. 

PFFS Beneficiaries Who Did Not Contact Their Plans to Determine Service 
Coverage before Receiving Services May Have Faced Unexpected Costs: 

If PFFS beneficiaries or their providers did not contact their plan 
before receiving a service to obtain an advance coverage determination, 
beneficiaries may have been responsible for the entire cost of the 
service if coverage for it was later denied by the plan because it was 
not medically necessary. Beneficiaries may have learned, from the 
information they received from their PFFS plan, whether a particular 
type of service would be covered, subject to a determination of medical 
necessity.[Footnote 29] However, from that information, the beneficiary 
would not know whether the plan would determine a service to be 
medically necessary in a specific instance. To ascertain before a 
specific service was received whether it would be covered, 
beneficiaries or their providers may request an advance coverage 
determination from the PFFS plan.[Footnote 30] CMS officials told us 
that they thought it was rare for beneficiaries in PFFS plans to face 
unexpected costs of denied claims, but they did not have data on the 
extent to which this occurs.[Footnote 31] 

Beneficiaries in other MA plans, such as HMOs and PPOs, generally had 
certain protections from unexpected costs when receiving services from 
network providers.[Footnote 32] Pursuant to CMS policy, when 
beneficiaries in other MA plans seek care from network providers and 
these providers are required to fulfill plan procedures to ensure 
coverage of services, such as obtaining a referral or prior 
authorization, beneficiaries are held harmless financially when 
providers fail to take these steps.[Footnote 33] In this circumstance, 
if beneficiaries in other MA plans reasonably believe that services 
would be covered, they would only be liable for their plan's cost 
sharing for the services, even if their plan later denies coverage. In 
addition, when these beneficiaries are responsible for taking steps to 
ensure coverage of services they receive from network providers, 
providers are required to inform beneficiaries of their 
responsibilities before providing these services. If the providers fail 
to do so, beneficiaries are responsible only for their plans' cost 
sharing for the services even if their plans later deny coverage. 
Because virtually all PFFS plans did not have provider networks, they 
did not provide these beneficiary protections. 

Beneficiaries in Medicare FFS also had protection from the unexpected 
costs of claims that were denied when services provided were 
subsequently determined to be not medically necessary. Specifically, 
beneficiaries in Medicare FFS generally are protected from incurring 
financial liability if they do not receive an advance beneficiary 
notice notifying them when Medicare is expected to deny coverage for a 
given service because it was not medically necessary. 

Some PFFS plans--plans administered by four of the nine PFFS plan 
sponsors we reviewed--required their providers, under the terms and 
conditions of the plans, to inform beneficiaries if a specific service 
was likely to be denied by the plan. However, these terms and 
conditions did not specify the penalty, if any, for not complying with 
this requirement. The terms and conditions of the remaining five plan 
sponsors did not require that providers notify beneficiaries if a 
service was likely to be denied by the plan. 

Even When Certain Services Were Covered, Some PFFS Beneficiaries Likely 
Experienced Higher Cost Sharing If They Did Not Contact Their Plans 
before Receiving Such Services: 

Beneficiaries in some PFFS plans were responsible for higher cost- 
sharing amounts if they (or their health care providers) did not 
contact their plans in advance (a process called prenotification) 
before obtaining certain covered services. Under CMS policy, PFFS plans 
can vary cost sharing depending on whether beneficiaries (or their 
providers) have notified the plan before receiving certain services. 
Four of the nine PFFS plan sponsors in our review offered plans that 
charged higher cost sharing if prenotification did not occur for 
certain services, such as inpatient hospital stays, durable medical 
equipment, inpatient mental health services, and skilled nursing 
services. The specific services subject to prenotification requirements 
and the amount of additional cost sharing varied by PFFS plan and could 
have been substantial (see table 3), as the following examples 
illustrate. 

* Three PFFS plan sponsors offered plans that required prenotification 
for inpatient hospital stays. Plans offered by two of the three PPFS 
plan sponsors increased required cost sharing by $100 to $150 per 
inpatient hospital admission without prenotification, while plans 
offered by the third sponsor required an additional $50 per day up to a 
maximum of $500 per admission. 

* Four PFFS plan sponsors offered plans that required prenotification 
for durable medical equipment, and doubled, or more than doubled, 
beneficiary coinsurance rates if prenotification did not occur. One 
plan increased the coinsurance rate for durable medical equipment and 
prosthetic devices from 30 percent to 70 percent for items that cost 
more than $750 if beneficiaries or their providers did not prenotify. 
In these plans, for example, cost sharing for beneficiaries who 
purchased a power wheelchair for approximately $4,000 could increase 
from about $1,200 if they notified their plan to about $2,800 if they 
did not. 

* Three PFFS plan sponsors offered plans that required prenotification 
for inpatient mental health stays and increased cost sharing in amounts 
ranging from $100 per admission to $50 per day up to a maximum of $500 
if prenotification did not occur. 

* One PFFS plan sponsor offered plans that required prenotification for 
skilled nursing facility stays and increased cost sharing by $50 per 
day up to a maximum of $500 if prenotification did not occur.

[End of table] 

In contrast to PFFS plans, the other MA plans we reviewed did not 
appear to have prenotification requirements for services received from 
network providers. CMS officials noted that prenotification was 
generally unnecessary in HMOs, which accounted for about 89 percent of 
beneficiaries in other MA plans in April 2007, because HMOs typically 
had a primary care physician who authorized care for the beneficiary. 
[Footnote 34] CMS officials also confirmed that Medicare FFS does not 
have prenotification requirements. 

Administrators from one of the four plan sponsors that required 
prenotification told us that they did so for inpatient hospital stays 
and other services in order to help them identify beneficiaries for 
case and disease management and for discharge planning.[Footnote 35] 
Administrators from another plan sponsor stated that they decided to 
require prenotificiation for durable medical equipment because the 
benefit typically had a high likelihood of abuse. A representative from 
another plan sponsor said that when the plan was prenotified it 
determined whether the equipment was medically necessary and informed 
the beneficiary of the potential financial liability that would be 
associated with the use or purchase of the durable medical equipment. 
The same representative noted that durable medical equipment was often 
determined to be not medically necessary. 

Some PFFS plans we reviewed inappropriately used the term prior 
authorization rather than prenotification in the informational 
materials they distributed to beneficiaries, which may have caused 
confusion about beneficiaries' financial risks. CMS officials stated 
that PFFS plans should not have used the term prior authorization 
because PFFS plans are not permitted to deny service coverage due to 
lack of prior plan approval. 

Inconsistent information that CMS provided to PFFS plans may have 
contributed to some PFFS plans' inappropriate use of the term prior 
authorization. One source of CMS guidance--a CMS manual--incorrectly 
stated that PFFS plans' terms and conditions were required to indicate 
"whether the provider must obtain advance authorization from the PFFS 
organization before furnishing a particular service."[Footnote 36] CMS 
officials acknowledged when we interviewed them in April 2008 that this 
statement was incorrect and should be deleted from its manual; however, 
as of August 2008 it had not been deleted. 

Another source of inconsistent guidance from CMS was the data system 
that the agency used to obtain benefits information from PFFS and other 
MA plans. CMS officials explained that, prior to our inquiries, they 
did not realize that the Plan Benefit Package (PBP) software, which 
PFFS plans used to specify their benefits, did not allow plans to enter 
their prenotification information, but did allow plans to specify 
whether they had prior authorization requirements. As a result, some 
PFFS plans' summaries of benefits incorrectly indicated that these 
plans had prior authorization requirements. CMS officials said that 
they would update the PBP software for contract year 2010 to ensure 
that PFFS plans would be unable to specify prior authorization 
requirements and would make available a screen where PFFS plans could 
enter their prenotification information for specific services. 

Following our inquiries on prior authorization and prenotification, CMS 
issued guidance to all PFFS plan sponsors in May 2008 through an 
operational policy memorandum to clarify its policy in these areas. 
[Footnote 37] This policy memorandum reiterated that PFFS plans could 
not require prior authorization from providers or beneficiaries as a 
condition of coverage. Regarding prenotification, the policy memorandum 
clarified that PFFS plans could not impose penalties, but that they 
were permitted to offer cost-sharing reductions for complying with 
voluntary prenotification protocols. 

PFFS Plans Had Relatively High Beneficiary Disenrollment Rates and CMS 
Did Not Comply with Statutory Requirements to Mail Current Rates: 

From January through April 2007, beneficiaries in PFFS plans 
disenrolled at an average rate that was more than twice that of other 
MA plans, and we conclude that CMS did not comply with statutory 
requirements to mail disenrollment rates to Medicare beneficiaries for 
the previous 2 years for MA plans in their area. Furthermore, 
information CMS has provided to beneficiaries on MA plan disenrollment 
rates and reasons for disenrollment is outdated. 

Beneficiaries Disenrolled from PFFS Plans at a Higher Rate Than from 
Other MA Plans: 

Beneficiaries in PFFS plans were more than twice as likely to disenroll 
as beneficiaries in other MA plans from January through April 2007. 
PFFS beneficiaries disenrolled at an average rate of about 21 percent, 
compared to about 9 percent for beneficiaries in other MA plans. 
Disenrollment rates varied by plan, which could reflect plan-level 
differences in factors such as beneficiary satisfaction with care, 
service, and out-of-pocket costs. The range of disenrollment rates for 
PFFS plans--about 4 percent to 59 percent--was similar to the range of 
rates for other MA plans--about 2 percent to 54 percent.[Footnote 38] 
However, PFFS beneficiaries were more likely than other MA 
beneficiaries to be in a plan with high disenrollment rates. For 
example, about 19 percent of PFFS beneficiaries were in plans that 
experienced disenrollment rates of 30 percent or more. In contrast, 
only 3 percent of other MA beneficiaries were in plans that experienced 
such high disenrollment rates. Approximately 15 percent of PFFS 
beneficiaries, but about 65 percent of other MA beneficiaries, were in 
plans that had disenrollment rates below 10 percent. (See figure 1.)

through April 2007:

Notes: Percentages may not sum to 100 due to rounding. Results are 
based on disenrollment that occurred from January through April 2007 
for 158 PFFS plans in which 805,734 beneficiaries were enrolled and 
1,410 other MA plans in which 4,488,653 beneficiaries were enrolled in 
December 2006. The disenrollment rate for a given MA contract applies 
to all plans under that contract. Other MA plans include HMOs, local 
PPOs, regional PPOs, and PSOs. 

[End of figure] 

On average, disenrollees from PFFS plans were generally sicker compared 
to the average for all beneficiaries in PFFS plans. This pattern was 
also evident in other MA plans, although the average health status 
difference between disenrollees and all beneficiaries in these plans 
was less pronounced. Beneficiaries' risk scores indicated that the 
projected health care expenditures, on average, of disenrollees from 
PFFS plans were estimated to be about 6 percent higher than the average 
for all PFFS beneficiaries.[Footnote 39] Similarly, beneficiaries who 
disenrolled from other MA plans had projected health care expenditures 
that were, on average, estimated to be about 3 percent higher compared 
to average projected health care expenditures for all beneficiaries in 
other MA plans.[Footnote 40] 

PFFS disenrollment rates differed depending on beneficiaries' age group 
and location (see table 4). Older beneficiaries in PFFS plans tended to 
disenroll at higher rates. For example, PFFS beneficiaries age 85 and 
older had the highest disenrollment rate (about 25 percent) while 
beneficiaries younger than age 65 had the lowest disenrollment rate 
(about 18 percent). In contrast, there was no such relationship between 
age and disenrollment rates for other MA plans. Also, beneficiaries in 
PFFS plans who resided in urban areas were more likely than rural 
beneficiaries to disenroll, but this was not the case for other MA 
plans.

CMS Did Not Comply with Statutory Requirements to Mail Current 
Disenrollment Rates to Medicare Beneficiaries: 

We conclude that CMS did not comply with statutory requirements to mail 
disenrollment rates to Medicare beneficiaries prior to the annual 
coordinated election period.[Footnote 41] In creating the MA program 
(previously called the Medicare+Choice program), Congress required CMS 
to annually mail information to beneficiaries comparing MA plans, 
including PFFS plans.[Footnote 42] The mailings were required to 
contain information about each MA plan available in a beneficiary's 
area, including beneficiary disenrollment rates for the previous 2 
years, to the extent that these data were available.[Footnote 43] 

CMS officials informed us that they had not mailed disenrollment rate 
information to all Medicare beneficiaries since the Medicare & You 2001 
handbook was sent in fall 2000, but more recent data were available. MA 
plan sponsors are required to provide CMS with disenrollment rates for 
beneficiaries who had been enrolled in their plans.[Footnote 44] 
Although CMS did not respond to our questions about whether MA plan 
sponsors complied with requirements to provide CMS with disenrollment 
rates, CMS does have the information needed to calculate current 
disenrollment rates by using Medicare enrollment data. We used Medicare 
enrollment data from CMS to calculate disenrollment rates presented in 
this report for January through April 2007 and also in previous reports 
in 1996 and 1998.[Footnote 45] 

In response to our inquiries, CMS officials stated that there is no 
requirement to mail disenrollment rates to Medicare beneficiaries, but 
did not provide any explanation for the agency's position. We, however, 
disagree as under federal law, prior to each annual coordinated 
election period, CMS is required to provide to Medicare beneficiaries 
disenrollment rates for plans in their area to the extent these rates 
are available. Because we concluded that disenrollment rates for MA 
plans were available, CMS was required to include relevant 
disenrollment rates in annual mailings to Medicare beneficiaries to 
enable them to make informed choices about their Medicare coverage. 

CMS published disenrollment rates and reasons for disenrollment through 
MOC on Medicare's Web site. As of August 2008, this information was 
available through MOC based on data for 2004 and 2005. However, given 
the recent growth in PFFS plans, from about 109,000 beneficiaries in 
June 2005 to about 2.3 million beneficiaries in June 2008, 
disenrollment rates and reasons for disenrollment based on 
disenrollment in 2004 and 2005 may not accurately represent the 
experience of PFFS plans available to beneficiaries in 2008. CMS 
officials stated that information on beneficiaries' reasons for 
disenrollment is necessary to understand the underlying differences in 
disenrollment rates across plans. Nonetheless, CMS officials said that 
the disenrollment reasons survey was discontinued after 2005 due to 
budget constraints. A CMS official also noted that providing 
disenrollment rates without reasons for disenrollment would be 
misleading because one would not know the extent to which beneficiaries 
left a plan, for example, because another plan was less expensive or 
due to poor quality care. We disagree with CMS's position. Although it 
would be useful to know the reasons behind beneficiaries' disenrollment 
decisions, disenrollment rates alone can provide useful relative 
information about MA plans and prompt beneficiaries to investigate 
plans further. 

Conclusions: 

The substantial enrollment growth in PFFS plans shows that these plans 
are an attractive option for Medicare beneficiaries. Yet, beneficiaries 
in these plans may have faced unexpected out-of-pocket costs if plans 
denied coverage for services for which beneficiaries or their providers 
had not obtained an advance coverage determination. While officials 
from CMS did not believe that PFFS plans often denied services 
unexpectedly for not being medically necessary, it is important to 
determine the extent to which such denials occur. Having this knowledge 
would inform CMS and policy makers about whether additional protective 
measures or beneficiary educational efforts are warranted. It is also 
important that beneficiaries have accurate and current information 
about MA plans' policies and procedures. As such, ensuring that prior 
authorization guidance is accurate will help beneficiaries and 
providers better understand the obligations and financial risks 
associated with PFFS plans. Similarly, providing beneficiaries with 
current information about MA plan disenrollment rates would help them 
make more informed choices when considering enrolling in an MA plan. 

Recommendations for Executive Action: 

We recommend that the Acting Administrator of CMS take the following 
three actions: 

* investigate the extent to which beneficiaries in PFFS plans are faced 
with unexpected out-of-pocket costs due to the denial of coverage when 
they did not obtain an advance coverage determination from their plan; 

* ensure that CMS guidance on prior authorization accurately reflects 
CMS policy and that PFFS plan materials conform to CMS requirements; 
and: 

* mail to Medicare beneficiaries MA plan disenrollment rates for the 
previous 2 years for MA plans that are or will be available in their 
areas, as required by statute, and update disenrollment rates provided 
to Medicare beneficiaries through MOC. 

Agency and Other External Comments: 

We provided a draft of this report to CMS and AHIP for comment. CMS 
provided us with written comments that are reprinted in appendix II, 
and representatives from AHIP provided us with oral comments. 

CMS Comments: 

CMS stated that beneficiaries may have more certainty that a particular 
service will be covered if that service is obtained from a provider in 
a plan's network. As a consequence, CMS stated that it is important for 
beneficiaries in non-network plans (such as virtually all PFFS plans) 
to understand their rights and obligations. CMS advised that 
beneficiaries in non-network plans may want to consider obtaining 
advance determinations from their plans in appropriate circumstances. 
CMS said that it would continue to work closely with Congress, GAO, 
beneficiary advocacy groups, and other interested parties to ensure 
that beneficiaries receive appropriate health care and do not incur 
unexpected financial risks. 

CMS outlined the steps that it was taking, or planned to take, in 
response to each of our three recommendations. In response to our 
recommendation that CMS investigate the extent to which beneficiaries 
in PFFS plans are faced with out-of-pocket costs due to the denial of 
coverage when they did not obtain an advance coverage determination 
from their plan, CMS is examining coverage denials and complaints, and 
will be collecting new information from plans and refining its 
complaint tracking module to support this effort. In response to our 
recommendation that CMS ensure prior authorization guidance accurately 
reflects CMS policy, the agency described several steps it has already 
taken and planned to take to address the inaccuracies, including 
providing new guidance, modifying the PBP, and providing model terms 
and conditions that PFFS plans will be required to use in 2009. In 
response to our recommendation that CMS mail disenrollment rates to 
Medicare beneficiaries and update disenrollment rates through MOC, the 
agency commented that it had recently awarded a contract to obtain 
disenrollment rates and other performance metrics by late 2009. 
However, the agency was silent as to how it would distribute 
information on MA plan disenrollment rates to beneficiaries. 

AHIP Comments: 

In general, AHIP representatives thought the report could better 
highlight certain points related to prenotification, MIPPA, and case 
management, and AHIP representatives made several observations about 
other aspects of the report. 

AHIP representatives stated that, while our presentation of 
prenotification requirements was accurate, the report should have more 
clearly stated that we did not know the extent to which beneficiaries 
actually faced higher cost sharing as a result of not fulfilling 
prenotification requirements. They also stated that our discussion of 
MIPPA should have occurred earlier in the report given the potential 
impact of this legislation on PFFS plans, and suggested that our 
finding that all nine PFFS organizations in our study provided either 
case management or disease management services should have been given 
greater prominence in the report. We believe our methodology and 
findings regarding prenotification are clearly presented in the report 
and do not agree that clarifications are warranted. We also believe the 
placement and emphasis on MIPPA and case and disease management are 
appropriate given the focus and timing of our work. 

AHIP representatives made several other observations they thought might 
help clarify aspects of the report. They explained that prenotification 
was originally intended to protect beneficiaries by providing them with 
an incentive to contact their plan to determine whether a service was 
covered before the service was rendered. AHIP representatives informed 
us that CMS had posted standard terms and conditions on its Web site 
that would help to address use of incorrect terms by the industry. They 
also stated that one explanation for our finding that beneficiaries in 
PFFS plans were younger on average could be that younger beneficiaries 
were more likely to try new types of plans. In addition, AHIP 
representatives emphasized the importance of collecting information 
about beneficiary reasons for disenrollment and endorsed making this 
information available to beneficiaries. 

As agreed with your offices, unless you publicly announce the contents 
of this report earlier, we plan no further distribution until 30 days 
from the report date. At that time, we will send copies to the Acting 
CMS Administrator, appropriate congressional committees and others. The 
report also will be available at no charge on the GAO Web site at 
[hyperlink, http://www.gao.gov/].

Appendix I: Scope and Methodology: 

This appendix explains the scope and methodology that we used to 
address our reporting objectives that (1) compare the characteristics 
of beneficiaries in private fee-for-service (PFFS) plans to the 
characteristics of beneficiaries in other MA plans and Medicare FFS; 
(2) describe the financial risks that beneficiaries in PFFS plans face, 
compared to beneficiaries in other Medicare Advantage (MA) plans and 
Medicare fee-for-service (FFS), if they do not contact their plan prior 
to receiving services; and (3) compare the rates at which beneficiaries 
in PFFS plans disenroll to the rates for other MA plans and evaluate 
whether the Centers for Medicare & Medicaid Services (CMS) met 
statutory requirements to mail disenrollment rates to beneficiaries. 

To compare the characteristics of beneficiaries in PFFS plans, 
specifically age, gender, and residential location, to the 
characteristics of beneficiaries in other MA plans and Medicare FFS, we 
used Medicare enrollment data from CMS for April 2007 from the 
Management Information Integrated Repository (MIIR) database and data 
from CMS on the average risk score for each MA plan in 2007, which 
provide an indicator of the health status of the plan's beneficiaries. 
[Footnote 46] We focused our analysis on beneficiaries enrolled in five 
types of MA plans as of April 2007 that accounted for more than 99 
percent of the approximately 7.8 million beneficiaries in MA plans at 
that time--PFFS plans and four other types of MA plans-- Health 
Maintenance Organizations (HMO), Local Preferred Provider Organizations 
(PPO), regional PPOs, and Provider-Sponsored Organizations (PSO). 
[Footnote 47] Among beneficiaries in the five MA plan types in our 
analysis, we excluded those (1) who were in plans that have enrollment 
restrictions (i.e., employer plans, Special Needs Plans (SNP), and 
plans that only cover Medicare Part B services) and (2) who live 
outside the 50 states, the District of Columbia, and Puerto Rico. After 
implementing these exclusions, we analyzed data as of April 2007 for 
1,304,288 beneficiaries in 431 PFFS plans, 4,535,881 beneficiaries in 
1,567 other MA plans, and 31,680,824 beneficiaries in Medicare FFS. 
[Footnote 48] We used the Health Resources and Services 
Administration's Area Resource File for 2006 to obtain data on 
counties' level of urbanization.[Footnote 49] We defined new enrollees 
in PFFS and other MA plans as beneficiaries who were in a given MA plan 
type in April 2007, based on data from the MIIR database, but who were 
not in that same plan type in December 2006. To compare the health 
status of beneficiaries in PFFS plans, other MA plans, and Medicare 
FFS, we used plan-level risk scores from CMS as a proxy for health 
status. After excluding beneficiaries in employer plans, SNPs, and 
plans that only cover certain Medicare FFS services as described above, 
we analyzed risk scores for 430 PFFS plans in which 1,371,169 
beneficiaries were enrolled and 1,576 other MA plans in which 4,610,368 
beneficiaries were enrolled as of July 2007. 

To describe the financial risks that beneficiaries in PFFS plans face, 
compared to beneficiaries in other MA plans and Medicare FFS, if they 
do not contact their plan prior to receiving services, we reviewed 
relevant laws, regulations, documentation from CMS, and materials from 
nine PFFS plan sponsors interviewed that accounted for about 81 percent 
of PFFS enrollment in July 2007.[Footnote 50] We reviewed plan benefit 
information for 2008 provided to beneficiaries as well as provider 
terms and conditions of payment for 30 PFFS plans, accounting for more 
than half of each sponsor's total PFFS plan enrollment. We reviewed 
plan benefit information for 2008 provided to beneficiaries for 33 HMO 
or PPO plans operated by the same nine plan sponsors, accounting for 
more than half of each sponsor's total enrollment in other MA plans. If 
the plan's benefit information provided to beneficiaries explicitly 
stated that beneficiaries would face higher cost sharing for certain 
services if they or their provider did not notify the plan before 
receiving such services, we considered that plan to have a 
prenotification requirement. We also interviewed officials from CMS and 
the plan sponsors. Information gathered from our review of the benefit 
information provided to beneficiaries for PFFS and other MA plans may 
not be representative of, or generalizeable to, other types of plans 
offered by these plan sponsors or to other PFFS and other MA plans that 
were not in our sample. 

To compare the rates at which beneficiaries in PFFS plans disenroll to 
the rates for other MA plans, we used Medicare enrollment data from the 
MIIR database for 6,913,780 beneficiaries in MA plans in December 2006. 
Because MA plan selections for 2007 generally take effect from January 
through April 2007, we identified disenrollees as beneficiaries who 
were covered under a given MA contract in December 2006 but were no 
longer covered under that contract in April 2007 based on Medicare 
enrollment data.[Footnote 51] Because we calculated disenrollment at 
the MA contract level, we did not address the extent to which 
beneficiaries transferred from one plan to another within an MA 
contract. We chose to calculate disenrollment rates at the MA contract 
level, rather than at the MA plan level, for two reasons: (1) 
transferring from one plan to another within a contract can occur for 
administrative reasons and therefore may not reflect beneficiary 
decisions, and (2) a beneficiary's decision to transfer, for example, 
from a zero premium plan to a plan within the same MA contract that 
charges a premium and has a richer benefit package does not suggest 
dissatisfaction with the type of MA plan or the sponsor that 
administers it. We calculated disenrollment rates for each MA contract 
as the total number of beneficiaries who disenrolled from their MA 
contract divided by total enrollment in that contract.[Footnote 52] The 
disenrollment rate for an MA contract applies to all plans under that 
contract. 

We did not include beneficiaries in disenrollment rate calculations if 
they disenrolled involuntarily due to factors such as death, loss of 
Medicare eligibility, moving out of their MA contract's service area, 
or to administrative factors such as a change in their MA contract's 
service area or a termination of their MA contract or plan.[Footnote 
53] After excluding beneficiaries (1) in certain plans and locations as 
described above and (2) in contracts or plans that were terminated in 
2006 or 2007, we analyzed data for 158 PFFS plans accounting for 
805,734 beneficiaries and 169,465 disenrollees and for 1,410 other MA 
plans accounting for 4,488,653 beneficiaries and 392,704 disenrollees. 

We used risk scores for 2006--an indicator of projected health care 
expenditures--to compare the health status of disenrollees to 
beneficiaries overall in PFFS and other MA plans. To estimate average 
risk scores of disenrollees from PFFS and other MA plans, we used 2006 
beneficiary-level risk scores for 169,271 beneficiaries who disenrolled 
from PFFS plans and for 391,126 beneficiaries who disenrolled from 
other MA plans from January through April 2007. To estimate the average 
risk scores of beneficiaries overall in these plans, we used 2006 plan- 
level risk scores, which are based on 725,110 beneficiaries in 154 PFFS 
plans and 4,421,308 beneficiaries in 1,400 other MA plans in July 2006, 
and weighted each plan's risk score by its July 2006 enrollment. 
According to a CMS official, MA plans' risk scores generally decline 
over the course of a year, so a plan's risk score based on 
beneficiaries in the plan in July 2006 could be higher than it would 
have been based on beneficiaries in the plan in December 2006.[Footnote 
54] As a result, the actual percentage difference between the average 
projected health care expenditures for disenrollees in PFFS and other 
MA plans and beneficiaries overall in these plans may be larger than 
our estimates indicate. To evaluate whether CMS met statutory 
requirements to mail disenrollment rates to beneficiaries, we 
interviewed CMS officials, analyzed relevant federal laws and 
regulations, and reviewed information CMS provided to Medicare 
beneficiaries through, for example, Medicare Options Compare (MOC) on 
Medicare's Web site.[Footnote 55]

To: Vincent J. Ventimiglia. Jr. 
Assistant Secretary for Legislation: 
Department of Health and Human Services: 

From: [Signed by] Kerry Weems: 
Acting Administrator: 

Subject: Government Accountability Office (GAO) Draft Report: "Medicare 
Advantage: Characteristics, Financial Risks, and Disenrollment Rates of 
Beneficiaries in Private Fee-for-Service Plans" (GAO-09-25): 

Thank you for the opportunity to review and comment on the GAO Draft 
Report titled "Medicare Advantage: Characteristics. Financial Risks, 
and Disenrollment Rates of Beneficiaries in Private Fee-for-Service 
Plans" (GAO-09-25). The Centers for Medicare & Medicaid Services (CMS) 
is committed to ensuring that Medicare beneficiaries receive 
appropriate health care services. 

There are certain important elements that beneficiaries in a health 
plan offering coverage through non-network providers must consider. The 
report highlights one of those elements that using network providers 
may provide a greater degree of certainty that all procedural claims 
rules will be followed and a particular service will in fact be covered 
by the plan. Thus. it is important for beneficiaries in non-network 
plans to understand their rights and obligations. and they may want to 
consider obtaining advance determinations from their plans in 
appropriate circumstances. 

Consistent with GAO's recommendations, CMS is reviewing the adequacy of 
information that Medicare Advantage (MA) private fee-for-service (PFFS) 
plans have provided with respect to advance coverage determinations and 
notices. CMS has also clarified and is monitoring compliance with our 
rules that prohibit prior authorization for covered services. 

The CMS will continue to work closely with Congress. GAO, beneficiary 
advocacy groups. and other interested parties to ensure that 
beneficiaries receive appropriate health care and do not incur 
unexpected financial risks. 

GAO Recommendation: 

The GAO recommends CMS investigate the extent to which beneficiaries in 
PFFS plans are faced with unexpected out-of-pocket costs due to the 
denial of coverage where they did not obtain an advance coverage 
determination from their plan. 

CMS Response: 

We are looking at coverage denials and complaints to determine whether 
there may be a problem with the adequacy of communication between plans 
and members. and whether it suggests that beneficiaries are not 
sufficiently taking advantage of their rights to receive an advance 
coverage determination. 

On October 3, 2008, CMS published a summary of proposed data collection 
requirements for Medicare Advantage organizations (MAOs) in the Federal 
Register. CMS proposed to collect organization determinations and 
reconsiderations data from PFFS plans as well as other MA plans to 
ensure that PFFS plans are not inappropriately denying plan-covered 
services. CMS will monitor the number of denial of coverage cases 
generated by PFFS plans on a quarterly basis, and will release the 
final data collection requirements in December 2008. 

The CMS is also refining its process for prioritizing beneficiary 
complaints to ensure that access to care complaints entered into the 
complaint tracking module (CTM) receive first priority. We believe a 
systematic monitoring of complaints will enable CMS to identify those 
PFFS plans as well as other MA plans that are inappropriately denying 
their enrollees health care services. 

In cases of denied coverage of plan-covered services, the beneficiary 
has recourse to a comprehensive and well established appeals process 
that furnishes enrollees access to an independent review entity and 
additionally an administrative law judge (see 42 CFR Subpart M). Also, 
the plan is obligated to provide the beneficiary with a Notice of 
Denial of Medical Coverage, which explains the beneficiary's appeal 
rights and why the service was denied coverage. 

PFFS plans must cover all medically necessary services covered by 
Original Medicare, in addition to any supplemental services covered by 
the plan. PFFS plans must use Medicare's coverage rules to decide what 
services are medically necessary. If a service is medically necessary 
under Original Medicare, then the PFFS plan must cover the service. 
PFFS plans must ensure there is no difference in access to covered 
services between beneficiaries enrolled in a PFFS plan and 
beneficiaries enrolled in Original Medicare. 

GAO Recommendation: 

The GAO recommends CMS ensure guidance regarding prior authorization 
accurately reflects CMS policy and that PFFS plan materials conform to 
CMS requirements. 

CMS Response: 

We concur with the GAO's recommendation and have already taken several 
steps to ensure that guidance to plans accurately reflects CMS' policy 
that PFFS Plans cannot require prior authorization as a condition of 
coverage and PFFS plan materials conform to CMS requirements. 

* In the 2009 Call Letter released on March 17, 2008, CMS described its 
policy that PFFS plans may not require enrollees or providers to obtain 
prior authorization from the plan as a condition of coverage. CMS 
reiterated this policy in a memorandum to PFFS plans that was released 
on May 29, 2008. 

* CMS modified the Plan Benefit Package (PBP) for contract year 2010 so 
that PFFS plans are no longer able to indicate that they have prior 
authorization requirements. 

* On September 12, 2008. CMS released a memorandum to PFFS plans titled 
"Instructions For Model Private Fee-For-Service Terms And Conditions of 
Payment". This memorandum provided PFFS plans with a model terms and 
conditions of payment, which reiterated CMS' policy that prior 
authorization cannot be required as a condition of coverage when 
medically necessary, plan-covered services are furnished to enrollees. 
CMS also indicated in this memorandum that, effective January 1, 2009, 
it expects all PFFS plans to have implemented the mode] terms and 
conditions of payment. 

* We are currently in the process of revising the Medicare Managed Care 
Manual to accurately reflect our policy on prior authorization for PFFS 
plans. 

* CMS will also review plan materials to ensure plan materials 
accurately describe CMS' prior authorization requirements. 

GAO Recommendation: 

The GAO recommends CMS comply with statutory requirements to mail to 
Medicare beneficiaries MA plan disenrollment rates for the previous two 
years for MA plans that are or will be available in their areas, and 
update disenrollment rates provided to Medicare beneficiaries through 
MOC. 

CMS Response: 

The CMS has recently awarded a contract to develop performance metrics 
for Medicare Advantage plans, including PFFS plans. CMS will have 
information on PFFS disenrollment rates from this contract by late 
2009. 

Again, we thank you for the opportunity to review and comment on this 
draft report.

persons age 65 and older, certain individuals with disabilities, and 
individuals with end-stage renal disease. Medicare Part A covers 
hospital and other inpatient stays. Medicare Part B is optional 
insurance, and covers hospital outpatient, physician, and other 
services. Medicare Parts A and B are known as Medicare FFS.

[7] We use the term other MA plans to refer to network-based HMOs, 
PPOs, and Provider-Sponsored Organizations (PSO). Beneficiaries in HMOs 
are generally restricted to seeing providers within a network. 
Beneficiaries in regional and local PPOs can see both in-network and 
out-of-network providers but usually must pay higher cost-sharing 
amounts if they use out-of-network services. A regional PPO serves an 
entire state or multiple states, whereas local PPOs may serve a county, 
partial county, or multiple counties. PSOs are operated by a provider 
or a group of affiliated providers where a substantial proportion of 
health care services are provided directly through the provider or 
providers. 

[8] A PFFS plan sponsor must demonstrate to the Secretary of Health and 
Human Services that it has a sufficient number and range of providers 
willing to furnish services under the plan by either (1) the plan 
establishing provider payment rates that are not less than the rates 
that apply under Medicare FFS, (2) the plan establishing contracts or 
agreements with a sufficient number and range of providers to furnish 
the services covered under the PFFS plan, or (3) a combination of the 
two options. 42 U.S.C. § 1395w-22(d)(4). Hereafter in this report, we 
refer to organizations offering MA plans, including PFFS plans, as plan 
sponsors. 

[9] PFFS plans may treat providers as if they have a written contract 
with the plan if before rendering covered services, the provider has 
been informed of the beneficiary's enrollment in the plan and knows of, 
or had a reasonable opportunity to obtain, the terms and conditions of 
the plan. 42 U.S.C. § 1395w-22(j)(6). 

[10] Congressional Research Service (CRS), CRS Report for Congress: 
Private Fee for Service (PFFS) Plans - How They Differ From Other 
Medicare Advantage Plans (Washington, D.C.: 2007). 

[11] PFFS plans must pay providers at a rate determined by the plan on 
a fee-for-service basis without placing the provider at financial risk. 
The plans also may not vary the rates for a provider based on the 
utilization of that provider's services nor restrict enrollees' choices 
among providers who are lawfully authorized to provide services and 
agree to accept the plan's terms and conditions of payment. 42 U.S.C. § 
1395w-28(b)(2). 

[12] CMS is an agency within the Department of Health and Human 
Services (HHS), to which HHS has delegated the responsibility for 
administering the Medicare program. 

[13] MA plan sponsors must have procedures for making timely 
determinations on whether a beneficiary is entitled to receive a 
service and the amount, if any, the beneficiary must pay for the 
service. 42 U.S.C. § 1395w-22(g)(1). 

[14] Medicare Program: Establishment of the Medicare+Choice Program, 63 
Fed. Reg. 34968, 35042-43 (June 26, 1998). 

[15] At least 15 days prior to each year's annual coordinated election 
period, the Secretary of Health and Human Services is required to mail 
to each Medicare beneficiary information comparing MA plans that are or 
will become available in the beneficiary's area including, to the 
extent available, disenrollment rates for the previous 2 years 
(excluding disenrollment due to death or moving outside the plan's 
service area). The Secretary must also mail this same information, to 
the extent practicable, to newly eligible Medicare beneficiaries at 
least 30 days prior to the beginning of the individuals' initial 
enrollment period under the MA program. 42 U.S.C. §§ 1395w-21(d)(2)(A), 
(B). 

[16] Pub. L. No. 110-275, §§ 162-163, 122 Stat. 2494 (codified, as 
amended, at 42 U.S.C. § 1395w-22(d), (e)). CMS has also published an 
interim final rule to implement these statutory requirements. 73 Fed. 
Reg. 54226 (Sept. 18, 2008). 

[17] PFFS plans will need to demonstrate that their networks meet 
criteria now applicable to other MA plans, including (1) ensuring, when 
medically necessary, benefits are available 24 hours a day and 7 days a 
week, and (2) providing access to appropriate providers, including 
specialists for medically necessary services. A network-based plan is 
defined as (1) an MA plan that is a coordinated care plan, (2) a 
reasonable cost reimbursement plan under section 1876 of the Social 
Security Act, or (3) a network-based Medical Savings Account plan. A 
network-based plan does not include regional PPOs that do not meet 
provider access standards through written contracts. 

[18] Beginning in 2011, PFFS plans that are sponsored by employers or 
unions, however, must contract with providers as part of a network 
regardless of their location. 

[19] Unlike other MA plan sponsors, PFFS plan sponsors are currently 
exempt from the requirement to have quality improvement programs and 
are, therefore, not required to report certain quality-related 
information to CMS. 

[20] We analyzed beneficiaries in Medicare FFS who had both Medicare 
Part A and Part B. We excluded plans with certain enrollment 
restrictions, such as plans that restrict enrollment to members of an 
employer group, plans that cover only Medicare Part B services, and 
beneficiaries in plans who live outside the 50 states, the District of 
Columbia, and Puerto Rico. 

[21] The nine PFFS plan sponsors in our review were Blue Cross Blue 
Shield of Michigan; Coventry Health Care, Inc.; Geisinger Health 
System; Humana, Inc.; Metropolitan Health Plan; Sterling Life Insurance 
Company; Universal American Corporation; University of Pittsburgh 
Medical Center Health Plan, Inc.; and Wellpoint, Inc. We selected the 
largest five PFFS plan sponsors based on enrollment in July 2007 and 
randomly selected three PFFS plan sponsors with enrollment that ranked 
between the 10th and 50th percentile among all PFFS plan sponsors. We 
also selected one plan sponsor that was the first to offer a PFFS plan. 

[22] We excluded plans with certain enrollment restrictions and 
beneficiaries in plans who live outside the 50 states, the District of 
Columbia, and Puerto Rico. 

[23] An MA contract is an agreement between CMS and an MA plan sponsor 
that covers one or more MA plans of the same type. For example, a 
contract between CMS and a plan sponsor may cover at least one PFFS 
plan or possibly several PFFS plans. 

[24] Medicare Options Compare is available at [hyperlink, 
http://www.medicare.gov]. Beneficiaries also can call 1-800-MEDICARE 
and have printed information sent to them if they do not have Internet 
access, or contact their State Health Insurance Assistance Program for 
help in choosing a plan. 

[25] Individuals with end-stage renal disease are not eligible to 
enroll in most MA plans. However, if these individuals develop the 
disease while enrolled in an MA plan, they may remain enrolled in their 
plan or change plans if their plan is terminated. 42 U.S.C. §1395w- 
21(a)(3)(B). 

[26] MA plans do not cover hospice care, a benefit that is provided 
under Medicare FFS. 

[27] Medicare beneficiaries enrolled in an MA Medical Savings Account 
plan generally may not disenroll during the open enrollment period. 
There are other circumstances when Medicare beneficiaries can disenroll 
from MA plans. For example, institutionalized Medicare beneficiaries 
may disenroll from MA plans and elect other plans or Medicare FFS at 
any time during the year. Medicare beneficiaries may also disenroll 
from MA plans during special election periods as approved by CMS. 

[28] We use the term medically necessary to refer to Medicare-covered 
services that are needed for the diagnosis and treatment of a 
beneficiary's medical condition and meet accepted standards of medical 
practice. 

[29] When beneficiaries enroll in any type of MA plan, including PFFS 
plans, and annually thereafter, the plan sponsor is required to furnish 
them with certain information, including the services that are covered 
(when medically necessary) and the associated cost-sharing obligations. 

[30] MA plan sponsors and providers are also required to furnish 
beneficiaries with certain written notices indicating when their 
coverage in inpatient facilities will end and when the plan denies 
coverage for a service. These notices include the Important Message 
from Medicare About Your Rights, Notice of Medicare Non-Coverage, 
Notice of Denial of Medical Coverage, and Detailed Explanation of Non- 
Coverage. In addition, PFFS plans may allow certain providers who 
render services to PFFS beneficiaries to receive up to 115 percent of 
the contracted payment rate and bill beneficiaries the amount that 
exceeds the contracted rate. In this circumstance, before rendering 
services, hospitals must provide PFFS beneficiaries with an estimate of 
the cost for which the beneficiaries will be responsible. 

[31] All beneficiaries enrolled in MA plans, including PFFS plans, can 
file an appeal if their plan will not pay for a service that a 
beneficiary thinks should be covered or provided. 

[32] CMS officials stated that, similar to beneficiaries in PFFS plans, 
beneficiaries in PPO plans receiving services from out-of-network 
providers that do not contact their plan in advance to determine 
service coverage may face unexpected costs if coverage is later denied. 

[33] 70 Fed. Reg. 4588, 4618 (Jan. 28, 2005); 42 C.F.R. § 422.504(g). 

[34] We calculated the percentage of MA beneficiaries in HMOs after 
excluding beneficiaries who (1) were in plans with certain enrollment 
restrictions (i.e., employer plans, Special Needs Plans, plans that 
only cover Medicare Part B services) or (2) lived outside the 50 
states, the District of Columbia, and Puerto Rico. 

[35] Case and disease management are designed to help coordinate and 
manage beneficiaries' care. Discharge planning facilitates 
beneficiaries' discharge from a hospital. Representatives from all nine 
PFFS plan sponsors we interviewed stated that they offered either case 
or disease management to their beneficiaries, and eight sponsors stated 
that they also conducted discharge planning.

authorization and referral requirements and 2009 PBP guidance; 
Additional guidance on prior notification rules, May 29, 2008. CMS had 
previously issued guidance for PFFS plans on prior authorization and 
prenotification in its 2009 Call Letter, dated March 17, 2008. 

[38] To calculate this range, we excluded 10 of 158 PFFS plans and 95 
of 1,410 other MA plans that were under MA contracts with fewer than 
250 beneficiaries. 

[39] All PFFS beneficiaries include those individuals who remained 
enrolled in their plans and those who subsequently disenrolled. 

[40] These results may underestimate the percentage difference in 
projected health care expenditures between disenrollees and 
beneficiaries overall in PFFS and other MA plans. See appendix I for 
more detail. 

[41] See 42 U.S.C. § 1395w-21(d)(2)(A). 

[42] Balanced Budget Act of 1997, Pub. L. No. 105-33, § 4001, 111 Stat. 
251, 276-286 (1997) (adding new section 1851 to the Social Security 
Act) (codified, as amended, at 42 U.S.C. § 1395w-21). 

[43] At least 15 days prior to each year's annual coordinated election 
period, the Secretary is required to mail to each Medicare beneficiary 
information comparing MA plans that are or will become available in the 
beneficiary's area including, to the extent available, disenrollment 
rates for the previous 2 years (excluding disenrollment due to death or 
moving outside the plan's service area). 42 U.S.C. § 1395w-21(d)(2)(A); 
see also Gray Panthers Project Fund, et al. v. Thompson, 273 F.Supp.2d 
32 (D.D.C. 2002) (holding that the Secretary was required to comply 
with statutory mandates requiring mailing of comparative information to 
MA beneficiaries "even if compliance is cumbersome, burdensome, or 
costly"). In addition, the Secretary must mail these disenrollment 
rates, to the extent practicable, to newly eligible Medicare 
beneficiaries at least 30 days prior to the beginning of the 
individuals' initial enrollment period under the MA program. 42 U.S.C. 
§ 1395w-21(d)(2)(B). 

[44] MA plan sponsors must provide, on an annual basis, the information 
necessary to enable CMS to provide current and potential Medicare 
beneficiaries the information they need to make informed decisions with 
respect to available choices for Medicare coverage. See 42 U.S.C. § 
1395w-21(d)(7), see also 42 C.F.R. § 422.64. In addition, as required 
under the contract between CMS and MA plan sponsors, plan sponsors 
specifically must provide to CMS disenrollment rates for Medicare 
beneficiaries for the previous 2 years. 42 C.F.R. § 422.504(f)(2). 

[45] See GAO, Medicare: Many HMOs Experience High Rates of Beneficiary 
Disenrollment, [hyperlink, http://www.gao.gov/products/GAO/HEHS-98-142] 
(Washington, D.C.: Apr. 30, 1998); and Medicare: HCFA Should Release 
Data to Aid Consumers, Prompt Better HMO Performance, [hyperlink, 
http://www.gao.gov/products/GAO/HEHS-97-23] (Washington, D.C.: Oct. 22, 
1996). 

[46] These risk scores were calculated for beneficiaries enrolled in 
July of that year and were normalized so that the average risk score 
for Medicare FFS beneficiaries was approximately 1.00. 

[47] We did not include the 2,223 beneficiaries in Medical Savings 
Account plans as of April 2007 in our analysis because these plans 
operate differently from other MA plan types. Beneficiaries in a 
Medical Savings Account plan receive annual deposits from CMS into an 
interest-bearing account to help them cover their health care costs 
until they have reached their plan's deductible, after which the plan 
is responsible for all Medicare-covered costs. 

[48] We analyzed beneficiaries in Medicare FFS who had both Part A and 
Part B. 

[49] We defined urban areas as those areas that are either classified 
as Metropolitan Statistical Areas or Micropolitan Statistical Areas. 
Metropolitan Statistical Areas have at least one urbanized area with a 
population of 50,000 or more, plus adjacent territory that has a high 
degree of social and economic integration with the core as measured by 
commuting ties. Micropolitan Statistical Areas have at least one urban 
cluster with a population of at least 10,000 but less than 50,000, plus 
adjacent territory that has a high degree of social and economic 
integration with the core as measured by commuting ties. We defined 
rural areas as those that are neither Metropolitan Statistical nor 
Micropolitan Statistical Areas and are not unknown. 

[50] The nine PFFS plan sponsors in our review were Blue Cross Blue 
Shield of Michigan; Coventry Health Care, Inc.; Geisinger Health 
System; Humana, Inc.; Metropolitan Health Plan; Sterling Life Insurance 
Company; Universal American Corporation; University of Pittsburgh 
Medical Center Health Plan, Inc.; and Wellpoint, Inc. We selected the 
largest five PFFS plan sponsors based on enrollment in July 2007 and 
randomly selected three PFFS plan sponsors with enrollment that ranked 
between the 10th and 50th percentile among all PFFS plan sponsors. We 
also selected one plan sponsor that was the first to offer a PFFS plan. 

[51] An MA contract is an agreement between CMS and an MA plan sponsor 
that covers one or more MA plans of the same type. For example, a 
contract between CMS and a plan sponsor may cover at least one PFFS 
plan or possibly several PFFS plans. 

[52] When calculating disenrollment rates for PFFS and other MA plans 
overall, we divided the total number of disenrollees by total 
enrollment in these plans. 

[53] The number of beneficiaries in these plans includes 8,918 
beneficiaries in PFFS plans and 79,827 beneficiaries in other MA plans 
who disenrolled involuntarily and were not included in the calculation 
of disenrollment rates. 

[54] This official noted that the decline in a plan's risk score over 
the course of a year occurs because plans generally have a higher 
proportion of new Medicare beneficiaries (i.e., beneficiaries age 65 to 
67 who have relatively low risk scores) at the end of the year and some 
older beneficiaries die who have relatively high risk scores. A plan's 
risk score, according to a CMS official, can decrease from, for 
example, 1.00 for beneficiaries in the plan in January to 0.95 for 
beneficiaries in the plan in December. 

[55] Medicare Options Compare is available at [hyperlink, 
http://www.medicare.gov]. Beneficiaries can also call 1-800-MEDICARE 
and have printed information sent to them if they do not have Internet 
access, or contact their State Health Insurance Assistance Program for 
help in choosing a plan.
