FAQ

May Medicaid programs bill Medicare directly?

No.  States typically do not meet the definition of a covered health care provider, and therefore, are not eligible to receive a National Provider Identifier (NPI) number to enable them to bill Medicare.  The NPI is the standard unique identifier for health care providers that CMS adopted in 2007.  At that time, Medicare revoked existing billing numbers previously issued to Medicaid agencies and notified Medicare carriers to stop enrolling Medicaid programs as Medicare providers.  Only recognized providers and suppliers of services that have an NPI can enroll in Medicare.  Medicare will not enroll state Medicaid programs, as they are not direct providers or suppliers of services.   

Medicaid may submit claims to health plans on behalf of Medicaid beneficiaries who have assigned their rights to payment from third parties (other than Medicare) to the Medicaid program, under the authority of sections 1912, 1902(a)(25)(H), and 1992(a)(25)(I)(ii) of the Social Security Act.  However, Medicaid doesn’t have the same authority to submit claims to Medicare on behalf of a “dually” eligible beneficiary.  The rights to Medicare benefits are not assignable; only the Medicare provider and the beneficiary may submit claims to Medicare.
