DON M. NEWMAN, ACTING SECRETARY OF HEALTH AND HUMAN SERVICES, ET AL. V. SANDRA EVERHART, ET AL. No. 88-1323 In the Supreme Court of the United States October Term, 1988 The Acting Solicitor General, on behalf of the Acting Secretary of Health and Human Services, petitions for a writ of certiorari to review the judgment of the United States Court of Appeals for the Tenth Circuit in this case. Petition For A Writ Of Certiorari To The United States Court Of Appeals For The Tenth Circuit PARTIES TO THE PROCEEDINGS The petitioners are the Acting Secretary of Health and Human Services and the Commissioner of the Social Security Administration. The respondents are plaintiffs Sandra and Thomas Everhart and Myron Zenick and intervenors Emil Zweizen and Berline Wise, representing a Tenth Circuit-wide class of Title II and Title XVI beneficiaries, certified by the district court, whose erroneous payments "were recovered pursuant to the Secretary's netting regulations on or after December 8, 1986" and who "have made or will make a claim to the Secretary not to have the netting policy applied in their cases" (App., infra, 27a).

JURISDICTION The judgment of the court of appeals was entered on August 12, 1988. A petition for rehearing with suggestion for rehearing en banc was denied on October 24, 1988. On January 13, 1989, Justice White extended the time for filing a petition for a writ of certiorari to February 7, 1989. The jurisdiction of this Court is invoked under 28 U.S.C. 1254(1). STATUTORY AND REGULATORY PROVISIONS INVOLVED Section 204(a)(1), 204(b), 42 U.S.C. 404(a)(1), 404(b) and Section 1631(b)(1), 42 U.S.C. 1383(b)(1) of the Social Security Act are set forth in the Appendix at 28a-312. Social Security regulations 20 C.F. R. 404.504 and 416.538 are set forth in the Appendix at 31a-35a. QUESTION PRESENTED Whether Social Security regulations that require netting of all errors in a recipient's past benefit payments to determine whether there has been an overpayment subject to recovery or waiver of recovery are within the agency's statutory authority. STATEMENT This case concerns the validity of Social Security regulations that require the "netting" of past overpayments and underpayments of benefits before determining whether any recoupment of overpayments should be waived. 1. Each month, the Social Security Administration (SSA), a unit of the Department of Health and Human Services (HHS), mails more than 40 million checks to beneficiaries under Title II of the Social Security Act, 42 U.S.C. 401 et seq. (Act) -- the Old Age, Survivors, and Disability Program -- and Title XVI of the Act -- the Supplemental Security Income (SSI) Program. Most of these checks correctly reflect the amount of benefits that the recipient is entitled to receive. In any program of this magnitude, however, mistakes are inevitable. Overpayments may occur due to inaccurate reports of actual or estimated income by beneficiaries (see 42 U.S.C. 403(a), 415), erroneous computation of statutory offsets (see 42 U.S.C. 402(j), 402(k)(3)), unreported workers' compensation benefits (42 U.S.C. 424a), administrative errors, or delays in the termination of benefits after entitlement has ended. Underpayments may come about because of beneficiaries' inaccurate reports of actual or estimated income, delays in establishing entitlement to receive benefits, erroneous terminations, and administrative errors. Section 204 of Title II and Section 1631(b)(1) of Title XVI, 42 U.S. C. 404 and 1383(b)(1), require the Secretary of Health and Human Services to correct errors in past payments whenever the beneficiary has received "more or less" than the amount to which he is entitled. The Title II provision, Section 204(a)(1), states that "(w)henever the Secretary finds that more or less than the correct amount of payment has been made to any person under (Title II), proper adjustment or recovery shall be made, under regulations prescribed by the Secretary." If the Secretary determines that "less than the correct amount" has been paid, the recipient is entitled to reimbursement of that amount. 42 U.S.C. 404(a)(1)(B). If a recipient has received "more than the correct amount," Section 204(a)(1)(A) permits the Secretary to "decrease any payment" under Title II to the recipient or to "require such overpaid person * * * to refund the amount." However, Section 204( b) directs that "there shall be no adjustment of payments to, or recovery by the United States" if the recipient was "without fault" and if "such adjustment or recovery would defeat the purpose of (Title II) or be against equity and good conscience." 42 U.S.C. 404(b). In Califano v. Yamasaki, 442 U.S. 682 (1979), this Court held that recipients who request a waiver under this section are entitled to an oral hearing prior to any recovery or adjustment of benefits. The parallel SSI provision is worded somewhat differently, but is similar in purpose and effect. Section 1631(b)(1) of Title XVI states that when the Secretary finds "that more or less than the correct amount of benefits has been paid" to a recipient, the Secretary shall make "proper adjustment or recovery." In the event that a beneficiary has been overpaid, Section 1631(b)(1)(B), 42 U.S.C. 1383(b)(1)(B), requires the Secretary to "make such provision as he finds appropriate * * * with a view to avoiding penalizing such individual * * * who was without fault," if an "adjustment or recovery * * * would defeat the purpose of this subchapter, or be against equity and good conscience, or (because of the small amount involved) impede efficient or effective administration * * *." The Secretary has been given express authority to promulgate regulations implementing these provisions, /1/ and has exercised that authority by adopting what are known as "netting" regulations. These regulations require that all overpayments and underpayments in past months be added or "netted" to yield a single payment error amount -- either a net underpayment or a net overpayment. See 20 C.F.R. 404.504 and 416.538. The Title XVI payment error regulation, 20 C.F.R. 416.538, defines "(t)he amount of an underpayment or overpayment" as "the difference between the amount paid to a recipient and the amount of payment actually due such recipient for a given period." The Title II regulation, 20 C.F.R. 404.504, contains a similar definition of "(t) he amount of an overpayment or underpayment." The Title XVI regulation also defines the "period" over which any errors in monthly payments are to be taken into account to "begin() with the first month for which there is a difference between the amount paid and the amount actually due for that month. The period ends with the month the initial determination of overpayment or underpayment is made." 20 C.F.R. 416.538. Thus, if the Secretary finds that a beneficiary has received an incorrect payment in the past, he is entitled to take into account all other payment errors beginning with the month the first error occurred and ending in the month the Secretary first discovers the mistake. Social Security Ruling (SSR) 81-19a (1981), provides that the "netting" period prescribed under the Title XVI regulation also applies to the calculation of a payment error amount under the Title II regulation, 20 C.F.R. 404.504. /2/ 2. a. The named respondents -- the three original plaintiffs and two intervenors in the proceedings below -- are each entitled to receive benefits under either Title II or Title XVI. The Secretary found that each of the respondents had received too much money during some past months and too little money in other months, and applied the netting regulations to calculate a net past payment error for each. The three original plaintiffs were found, after netting, to have incurred net underpayments. The Secretary accordingly paid them the net amount due. In accordance with the regulations, however, they were not afforded an opportunity to request a waiver of repayment with respect to the overpayments they had previously received. Respondents filed a class action in the United States District Court for the District of Colorado seeking declaratory and injunctive relief against the Secretary and the Commissioner of the SSA. They claimed that the Secretary's netting procedure violated the terms of the Social Security Act, and denied them due process of law under the Fifth Amendment of the United States Constitution. /3/ In their view, the statute required the Secretary to segregate past overpayments and past underpayments into separate accounts, to pay over the total amount of all past underpayments, and then to apply the waiver of recoupment procedures to the total of all past overpayments. Ruling from the bench, the district court (App., infra, 20a-25a) granted respondents' motion for summary judgment. Expressly disagreeing with the decision of the Third Circuit in Lugo v. Schweiker, 776 F.2d 1143 (1985), which had upheld the netting regulations against a similar challenge, the court concluded that the Secretary had accomplished an "end run * * * around both the waiver statutes and the Supreme Court's decision in Califano v. Yamasaki" (App., infra, 22a, quoting Lugo v. Schweiker, 776 F.2d at 1156 (Gibbons, J., dissenting)). The court remanded the respondents' claims to the Secretary for recalculation of their payment errors without using the netting method. The court further enjoined the Secretary from applying that method to any Title II and Title XVI beneficiaries in the State of Colorado. b. The court of appeals affirmed the judgment as to the named respondents. /4/ Although it acknowledged that "the Act does not specify over what past time period there must be a determination of payment errors" (App., infra, 11a), the court observed that "the statute is not silent regarding the differential treatment of overpayments and underpayments and the mandatory waiver of recovery in appropriate instances" (ibid.). Quoting from Judge Gibbons' dissenting opinion in Lugo v. Schweiker, supra, the court found that the practice of "offsetting past overpayments against underpayments" allowed the Secretary to "effectively recover() overpayments without complying with the statutorily mandated waiver of recoupment procedures" (id. at 10a). The court concluded that there were "inherent conflicts between the regulations and the recoupment and waiver of recoupments provisions," and held the regulations invalid for failing to require a separate calculation of total overpayments and total underpayments (id. at 13a). The court of appeals rejected the Secretary's argument that elimination of the netting methodology would "result in a much more complex system for dealing with payment errors" (App., infra, 11a n.5). Instead, the court found "reasonable" respondents' position that one notice containing a separate list of all overpayments and underpayments would comport with the statute, and concluded that such a requirement would impose on the Secretary "no greater burden to provide notices and hearings than that already imposed under the statute and the Supreme Court's interpretation of the waiver provisions." Id. at 12a n.5. REASONS FOR GRANTING THE PETITION The court of appeals' decision in this case will impose significant burdens on the Social Security Administration, both in terms of multiplying the number of waiver requests and hearings that must be considered, and in terms of the additional benefits that must be paid out but may never be recouped. Although the court perceived "inherent conflicts" between the netting regulations and the Social Security Act, those regulations are in fact entirely consistent with the language of both Section 204 and Section 1631(b). And even if there were any ambiguity in the statute, the court of appeals should have deferred to the Secretary's regulations, which promote administrative efficiency at the same time that they insure that no beneficiary will ever be subject to recoupment -- either by withholding of future benefits or by demand for repayment -- without first being afforded an opportunity to seek a waiver. As the court of appeals acknowledged, its decision is in direct conflict with decisions of the Third Circuit and the Eighth Circuit, both of which have scrutinized the netting regulations and found them lawful. Lugo v. Schweiker, 776 F.2d 1143 (3d Cir. 1985); Webb v. Bowen, 851 F.2d 190 (8th Cir. 1988). Review by this Court is therefore plainly warranted. 1. The court of appeals acknowledged that its role in reviewing the Secretary's netting regulations was a narrow one (App., infra, 5a): "Because the Social Security Act expressly entrusts the Secretary with the responsibility of implementing the Act by regulation, our review of the disputed regulations is limited to determining whether the regulations are arbitrary and capricious or are inconsistent with the statute." Although the court articulated the correct standard of review, see Chevron U.S.A. Inc. v. NRDC, Inc., 467 U.S. 837, 842-844 (1984); Heckler v. Campbell, 461 U.S. 458, 466 (1983), it went seriously astray in suggesting that the netting regulations are "inconsistent with the statute." The regulations are fully consistent with both the language of the Social Security Act and Congress's equitable goals in establishing a waiver of recoupment scheme. a. The statutory scheme makes clear that the correction of past payment errors proceeds in two steps. As set forth in the Title II provisions, the Secretary must first determine, under Section 204(a)( 1), whether "more or less" than the correct amount has been disbursed. If this inquiry reveals an underpayment, then the Secretary must automatically reimburse that amount to the beneficiary. If on the other hand the threshold inquiry reveals an overpayment, then it is necessary to move to the second stage, set forth in Section 204(b). That section provides that before the Secretary may seek any "adjustment in payments to, or recovery by the United States" from a beneficiary who is without fault, he must determine whether "such adjustment or recovery would defeat the purpose of this subchapter or would be against equity and good conscience." Section 204(b). /5/ The statute thus makes plain that the provision for a waiver, set forth in Section 204(b), is triggered only by an attempt by the Secretary to seek an "adjustment or recovery." It is the attempt to recoup that gives rise to the opportunity to seek a waiver, not the threshold determination that there has been one or more overpayments. The netting regulations, which require the Secretary to afford an opportunity for a waiver in every case where he seeks to recover an overpayment, are therefore fully consistent with the statute. The court of appeals appears to have collapsed the two statutory inquiries into a single stage, reading the statutes as if they required an opportunity for a waiver whenever there is, for one or more months in the past, an overpayment. This would account for the court's statement (App., infra, 11a) that "the statute is not silent regarding the differential treatment of overpayments and underpayments and the mandatory waiver of recovery in appropriate instances." There is nothing in either statute, however, to suggest that the identification of one or more monthly overpayments by itself triggers the opportunity for a waiver. /6/ The statutes make clear that a waiver must be considered only when the Secretary seeks to make "an adjustment or recovery." In effect, the court moved the provision for waiver of recovery from Section 204(b) to Section 204(a). The court's holding that the netting regulations violate the statute would follow only if the terms that trigger an opportunity for a waiver -- "adjustment or recovery" -- necessarily included the process of reducing past excess payments by netting them against past deficient payments. There is language in the court of appeals' opinion that suggests this view. See App., infra, 10a ("by offsetting overpayments against underpayments, the SSA has effectively recovered overpayments without complying with the statutorily mandated waiver of recoupment procedures"). And that was clearly the premise of Judge Gibbons' dissenting opinion in Lugo v. Schweiker, on which the court below heavily relied. See 776 F.2d at 1154 (footnote omitted) ("No recovery means no recovery by setoff, and no recovery by suit; no recovery at all."). The language and history of the waiver provisions make plain, however, that the words "adjustment or recovery" were intended to refer only to (i) the withholding of future benefits ("adjustment") or (ii) a legal demand for payment from the recipient or his estate ("recovery"). /7/ There is no suggestion in these materials that either of these terms was intended to encompass reductions of overpayments by offsets against past underpayments. b. Even if there were some ambiguity about the meaning of "adjustment or recovery," the court of appeals should not have resolved that ambiguity simply by adopting its own preferred answer to the interpretative question. When a court "determines Congress has not directly addressed the precise question at issue, the court does not simply impose its own construction of the statute, as would be necessary in the absence of an administrative interpretation. Rather, if the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency's answer is based on a permissible construction of the statute." Chevron, 467 U.S. at 843 (footnote omitted). Here, there can be no doubt that the Secretary's netting regulations are at the very least a "permissible" construction of the statute. Not only does the phrase "adjustment or recovery" permit of a construction consistent with the netting procedure, but the operative terms that define when there has been an overpayment or underpayment also permit the Secretary to adopt the methodology reflected in the regulations. Section 204(a) states that "(w)henever the Secretary finds that more or less than the correct amount of payment has been made" to a recipient, the Secretary shall make "proper adjustment or recovery" as prescribed. The term "more or less" is not defined in Section 204(a) or any other section, nor does the Act say over what past period of time the payment error determination may be made. Unlike the benefit provisions of the Social Security Act, which expressly require payments "for each month," see 42 U.S.C. 402(a), 423(a), 1382(c)(1), Section 204(a) does not contain any such limitation. Thus, it was entirely proper for the Secretary to define the appropriate period for determining whether a recipient has been paid "more or less" as the entire period between the month when an error first occurs and the month when that error (as well as other subsequent errors) is detected. 20 C.F.R. 416.538. /8/ Nor can there be any claim that the Secretary's construction is unreasonable. The primary purpose of the waiver provision is to protect subsistence-level beneficiaries against the hardship of having to repay a debt to the government out of their limited assets or through reduction in future benefits. This objective is consistent with Congress's general purpose in creating Titles II and XVI: to ensure that beneficiaries maintain a minimally adequate standard of living. See Lugo, 776 F.2d at 1152-1153; Beatty v. Schweiker, 678 F. 2d 359, 363 (3d Cir. 1982). The netting regulations respect this concern no less effectively than the court of appeals' system of separate accounting. Under the netting procedure, the Secretary may never reduce future benefits or bring an action to collect a refund without first affording the beneficiary the opportunity to seek a waiver. On the other hand, whereas the netting regulations insure that "netted" beneficiaries receive no less than the full amount to which the statute entitles them, the Tenth Circuit's rule requires that the Secretary deliberately make payments in excess of entitlements. Under netting, beneficiaries are automatically reimbursed for any difference between the total amount due and the amount actually paid -- that is, the net underpayment. Separate accounting, in contrast, requires the Secretary automatically to reimburse all underpayments, whether or not the beneficiary has already been repaid in the form of mistaken overpayments. Thus, the court of appeals' approach will in many instances require the Secretary to make additional payments to beneficiaries who already have been effectively "paid up." 2. The court of appeals, following the dissenting judge in Lugo v. Schweiker, supra, also suggested that the Secretary's netting regulations are contrary to this Court's decision in Califano v. Yamasaki, 442 U.S. 682 (1979). But as the majority pointed out in Lugo, Yamasaki in fact confirms the reasonableness of the Secretary's reading of the statute. In Yamasaki, the Court held that disputes concerning determinations of error under Section 204(a) require less stringent procedures than waiver determinations under Section 204(b). While the Court "required a hearing for determination of imprecise (Section 204(b)) standards such as 'fault,' it noted that disputes may arise over the (Section 204(a)) calculation of overpayment but there need be no hearing to resolve them." Lugo, 776 F.2d at 1149. The Yamasaki Court thus made clear that an oral hearing is not a necessary prerequisite to a determination whether "more or less" than the correct amount has been paid. In holding that the Secretary's method for ascertaining error deprives recipients of a hearing to which they are entitled, the Tenth Circuit's ruling interposes a procedural requirement that this Court has held does not apply. 3. As the court of appeals expressly acknowledged (App., infra, 9a-10a), its decision "creat(es) a split between circuits." /9/ In Lugo v. Schweiker, 776 F.2d 1143 (1985), a class action brought by an SSI beneficiary on behalf of a class of Title II and Title XVI beneficiaries, a divided panel of the Third Circuit upheld the Secretary's netting regulations. The Lugo court analyzed the regulations under the Chevron framework, and held that they reflected a reasonable exercise of the authority delegated to the Secretary by Congress. In so ruling, the court recognized that the statute prescribes a two-stage procedure. As the court stated, "Section (204( a)) compels the Secretary to make a finding concerning the erroneous payments at issue; only afterwards does (Section 204(b)) provide a hearing and an opportunity for waiver should SSA find that an overpayment occurred." 776 F.2d at 1149 (citation and footnote omitted). The court accordingly concluded that the waiver of recoupment provision applied only to the amount of overpayment as determined under Section 204(a), and the netting practice in no way compromised the recipient's right to a hearing prior to recoupment of overpayments. /10/ Similarly, in Webb v. Bowen, 851 F.2d 190 (1988), the Eighth Circuit considered and rejected an individual social security recipient's claim that the practice of netting violated Title II. /11/ The court in Webb agreed with the majority in Lugo that "Congress did not address the method to be used in determining the existence of an under or overpayment," 851 F.2d at 192, and concluded that "there is no statutory authority mandating that the Secretary use separate figures for each month, rather than the aggregate approach he has adopted." Ibid. As did the Lugo majority, the Webb panel construed Section 204( b) as conferring no more than the opportunity to waive "the amount found to be overpaid under section (204(a))," and reasoned that the Secretary's method therefore deprived recipients of no procedural rights conferred by the provision for equitable waiver. Both the Eighth and the Third Circuits recognized that neither the statute nor the legislative history definitively establishes the meaning of the phrase "more or less," which appears in Sections 204(a) and 1631(b)(1). Both acknowledged that by electing not to restrict the period over which the Secretary could determine whether "more or less" than the correct amount has been paid, Congress left to the Secretary's discretion the choice of such period. By applying the appropriate "arbitrary and capricious" standard of scrutiny under Chevron, 467 U.S. at 844, the Lugo and Webb panels concluded that a reasonable construction of the statute did not foreclose the Secretary's choice of method. In rejecting this line of reasoning, the Tenth Circuit's decision is squarely at odds with Lugo and Webb. 4. The issue in this case is of considerable practical importance, affecting hundreds of thousands of individual claims for adjustment of benefits under two of the largest federal entitlement programs. Between 1981 to 1986, an average of 4.7 million persons annually were affected by some form of payment error in the Title II retirement and survivor's insurance program alone. /12/ HHS estimates that it applies the netting procedure to about 300,000 retirement and survivors insurance program beneficiaries each year, and to thousands of others in the remaining programs (such as disability) under both Titles. The elimination of a method that allows a single determination of error for each beneficiary will result in an unwarranted multiplication of labor-intensive procedures, and in the disbursement of benefits in excess of substantive entitlements to thousands of beneficiaries every year. This in turn will dramatically increase the cost and difficulty of administering the programs and drain funds that would otherwise go to needy individuals. The Tenth Circuit rule, which requires calculation of at least two error amounts in all cases where netting produces one, has several practical consequences. First, because the government would receive no credit for past overpayments in computing past underpayments which must be automatically reimbursed, the total amount of money the Secretary must pay out will substantially increase. Those who would otherwise be overpaid after netting will be entitled to reimbursement; those who would be underpaid after netting will be entitled to larger amounts. /13/ The additional outlay for 300,000 recipients will be quite substantial, as the average error involved in each case of underpayment has been estimated at almost $600. GAO Report at 27. Regardless of whether these payments are eventually recovered, SSA will be obliged to set aside large reserves for reimbursement and new administrative costs. In addition, if netting is foreclosed, the more than 150,000 individuals per year /14/ who are currently found to be underpaid (because their total underpayments exceed their total overpayments) will be converted into beneficiaries with outstanding overpayments (because their underpayments will be automatically paid, leaving only overpayments). The multi-step task of processing this new pool of overpaid beneficiaries will demand considerable administrative effort. Even if waiver is not requested, the SSA must notify recipients of their right to request a waiver, answer inquiries and requests for explanations, review and resolve requests for reconsideration as to the fact or amount of overpayment, complete overpayment recovery questionaires, establish payback or future benefit adjustment schedules, monitor or suspend repayment on the basis of pending appeals, and institute collection actions. If a waiver is requested, then in addition the agency must engage in a comprehensive, case-by-case inquiry into the beneficiary's personal circumstances and the reasons for the mistaken payment in order to make decisions as to "fault," "defeat the purpose" and "equity and good conscience." /15/ The beneficiary must then be accorded a face-to-face hearing before waiver can be denied and recovery commenced. See Califano v. Yamasaki, supra. These procedures, however burdensome, serve an important and appropriate function in protecting subsistence-level beneficiaries against the loss of future benefits due to past mistakes that are no fault of their own. Surely it is perverse, however, to adopt a rule that in effect requires that beneficiaries be deliberately overpaid, and then subjected to these elaborate procedures before the Secretary may attempt recoupment. Congress never contemplated such a result, and the Secretary's considered regulations do not require it. The decision of the court of appeals in this case, which compels the Secretary to adopt such a procedure, is wrong and warrants further review by this Court. CONCLUSION The petition for a writ of certiorari should be granted. Respectfully submitted. WILLIAM C. BRYSON Acting Solicitor General JOHN R. BOLTON Assistant Attorney General THOMAS W. MERRILL Deputy Solicitor General AMY L. WAX Assistant to the Solicitor General WILLIAM KANTER MARY DOYLE Attorneys FEBRUARY 1989 /1/ Section 204(a)(1) of Title II, 42 U.S.C. 404(a)(1), itself directs that proper adjustment or recovery be made "under regulations prescribed by the Secretary." Both Title II and Title XVI also contain general provisions expressly delegating to the Secretary "full power and authority to make rules and regulations and to establish procedures, not inconsistent with the provisions of this subchapter, which are necessary or appropriate to carry out such provisions * * *." 42 U.S.C. 405(a), 1383(d)(1). See Heckler v. Campbell, 461 U.S. 458, 466-467 (1982). /2/ The Title II regulation was originally promulgated in 1955, see 20 Fed. Reg. 2,662, and was amended in 1969, see 34 Fed. Reg. 14,888. The Title XVI regulation, see 40 Fed. Reg. 47,763, was first adopted in 1975 to implement Section 1631, 42 U.S.C. 1383, which was enacted as part of the Social Security Amendments of 1972, Pub. L. No. 82-603, Section 109,86 Stat. 1475. The Title XVI regulation was revised in 1985 to eliniate a provision that required netting on a quarterly basis and to adopt the current method, which requires netting over the entire period in which past errors are uncovered. See 50 Fed. Reg. 48,573. /3/ Because both courts below held that the regulations violated the statute, neither considered the constitutional challenge. /4/ The court reversed the district court's grant of statewide injunctive relief on the ground that no class had been certified, and remanded for further proceedings (App., infra, 16a & n.7). On remand, the district court certified a circuit-wide class of Title II and Title XVI beneficiaries whose erroneous payments "were recovered pursuant to the Secretary's netting regulations on or after December 8, 1986" (App., infra, 27a) and who "have made or will make a claim to the Secretary not to have the netting policy applied in their cases" (ibid.). The Secretary was ordered to identify all class members by February 20, 1989 (ibid.). /5/ Although Section 1631(b) of Title XVI, unlike Section 204 of Title II, is not divided into two subsections, the many similarities in language and function between the two provisions indicate that they should be read in para materia. As in Title II, the Secretary must complete the determination whether "more or less" has been paid under Title XVI before taking the appropriate remedial measure. /6/ Neither Section 204(a)(1) nor Section 1631(b)(1) uses the terms "overpayment" and "underpayment" in the text of the statute (although those terms do appear in the headings). Instead, both provisions refer to the Secretary's finding that "more or less than the correct amount of benefits has been paid" to "any person" (Section 404(a)) or "with respect to any individual" (Section 1383(b)(1)(A)). This language does not suggest that different types of past mistakes should be rigorously segregated, or that the Secretary is expected to compute more than a single error amount. In fact, it suggests the contrary. The disjunctive "or" implies that the Secretary is expected to find one or the other type of error in each case. /7/ Section 1631(b)(1) in fact describes "adjustments" more fully as "appropriate adjustments in future payments to such individual * * *" (emphasis supplied). Thus, an "adjustment" cannot be an offset against past underpayments. And Section 204(a) describes a "recovery" more fully as "requir(ing) such overpaid person or his estate to refund the amount in excess of the correct amount * * *." This is language strongly suggestive of a legal demand for payment out of a beneficiary's separate assets. The history of the payment error provisions confirms these inferences drawn from the text. As originally enacted, the Social Security Act of 1935 permitted the government to recover overpayments of old-age benefits only by demanding repayment from the estate of recipients upon their death. See Pub. L. No. 74-271, Section 206, 49 Stat. 624. This section was modified in 1939, see Pub. L. No. 76-379, 53 Stat. 1368, and renumbered as Section 204, to permit recoupment of excess payments during the beneficiary's lifetime. The 1939 version of Section 204(a) expressly authorized only one method of recoupment -- "proper adjustment" by means of "increasing or decreasing subsequent payments to which such individual is entitled." By defining "adjustment" in terms of modification of subsequent benefits, Congress plainly indicated that an "adjustment" referred only to withholding from future benefits. At the same time, Congress was concerned about the possible hardship that withholding of future benefits might create, and therefore added Section 204(b) to allow a waiver in appropriate circumstances when the Secretary sought to make an "adjustment or recovery." Since the only two methods of recoupment that then existed were withholding of future benefits and a demand for payment from the recipient's estate, "adjustment" clearly referred to the former and "recovery" to the latter. This was confirmed by the Senate Report, which explained that Section 204(b) was intended to "waive() any right of the United States to recover by legal action or otherwise in any case of incorrect payments" to individuals without fault. S. Rep. No. 734, 76th Cong., 1st Sess. 51 (1939). In 1967, Congress amended Section 204 to enact the present version. Noting that the prior version of Section 204(a), by authorizing only withholding of future benefits and recovery from an estate, had created a loophole in cases where the recipient was still alive but benefits were no longer being paid, Congress added an additional method of recovery: a "refund." See S. Rep. No. 744, 90th Cong., 1st Sess. 94 (1967) ("Under the bill, the Secretary would have authority in any case where there has been an overpayment of cash benefits, to recover the overpayment by requiring a refund or by withholding the cash social security benefits (to anyone) getting benefits on the same earnings record, whether or not the overpaid person is alive."). See also id. at 257. The Report thus makes clear what is apparent from the statute itself: the terms "adjustment" and "recovery" refer respectively to the prospective remedial measures of (i) withholding of future benefits or (ii) legal action to recover a refund, either from a living recipient or from an estate. /8/ The court of appeals acknowledged that neither Section 204(a)(1) nor any other provision expressly specifies "over what past time period there must be a determination of payment errors." App., infra, 11a. It follows that "Congress (did) not directly address() the precise question at issue," Chevron, 467 U.S. at 843, and the court should have deferred to the Secretary's construction. /9/ In Griffin v. Califano, 448 F. Supp. 430 (N.D. Ga. 1977), the district court rejected a constitutional challenge to the netting regulations, but did not address the question of whether they violated the Social Security Act. The Fifth Circuit summarily affirmed the district court's decision. See Griffin v. Harris, 608 F.2d 1371 (1979). /10/ The court also rejected the claim that the netting regulations violated beneficiaries' rights to due process and equal protection under the Fifth Amendment. Lugo, 776 F.2d at 1151-1152. /11/ The court in Webb did not expressly rule on the legality of netting under the Title XVI provisions. /12/ See Social Security: Payment Accuracy Rates Are Overstated, United States General Accounting Office Report to the Chairmen, U.S. Senate Subcomm. on Labor, Health and Human Services, and Education, Comm. on Appropriations 19 (Oct. 1987) ("GAO Report"). /13/ For example, a beneficiary with $1000 in total underpayments and $500 in total overpayments during a past period would be entitled to reimbursement of $500 after netting. Under a separate accounting system, he would be entitled to reimbursement of $1000 -- $500 more than he would have received under the netting regulations. This extra $500 -- which previously would have been netted against his underpayment -- would now be considered an overpayment that must be recovered separately. Conversely, a beneficiary found to have a net past overpayment of $500 based on $500 in total past underpayments and $1000 in past overpayments would be entitled to no reimbursement under netting, but would owe the SSA $500. Under the system of separate accounting, the recipient would be entitled to $500 in reimbursement, and the SSA would be forced to attempt to recover a larger amount -- $1000 -- representing overpayments considered separately. In sum, the disallowance of netting will affect the distribution of funds in three ways: (1) the Secretary must disburse a larger amount of money to all beneficiaries with past mixed errors; (2) the Secretary must attempt to collect overpayments from a new class of beneficiaries not previously considered overpaid; and (3) the amount that the Secretary must attempt to collect from those previously considered overpaid will rise. /14/ HHS estimates that over 60% of all payment errors subject to correction (both "net" and "pure") are underpayments, see GAO Report at 27, and, by extension, that the group found underpaid after netting represents a majority of "netted" beneficiaries. /15/ The multiple criteria for a finding that a beneficiary is without fault are set forth at 20 C.F.R. 404.507, 510, 510a, 511 (Title II) and 416.552 (Title XVI). The determination involves a sophisticated exercise of administrative judgment based on a host of individualized factors. See, e.g., 20 C.F.R. 404.507 (the administrator "will consider all pertinent circumstances, including * * * age, intelligence, education, and physical and mental condition"); 20 C.F.R. 416.552 ("Whether the individual is 'without fault' depends on all the pertinent circumstances surrounding the overpayment in the particular case."). With respect to the "equity and good conscience" exemption, the regulations require the SSA to investigate whether the recipient "because of a notice that such payment would be made or by reason of incorrect payment, relinquished a valuable right * * * or changed (his condition) for the worse." 20 C.F.R. 404.509; see also 20 C.F.R. 404.512, 416.554. A "defeat the purpose" determination, in many instances, necessitates a comprehensive investigation of the beneficiary's financial circumstances to ascertain if recovery would "deprive (an individual) of income required for ordinary and necessary living expenses." 20 C.F.R. 404.508(a) (Title II) and 416.553 (Title XVI). Finally, Title XVI requires the administrator to decide whether the amount involved is too small to justify recovery by comparing the projected recoupment amount to the "administrative cost of handling" an overpayment case. See 20 C.F.R. 416.555. Appendix
