Third-Party Liability Payment Collections in Medicaid

Medicaid beneficiaries may have additional health insurance through third-party sources. Previous OIG work described problems that State Medicaid agencies had in identifying and collecting third-party payments. States are to take all reasonable measures to ascertain the legal liabilities of third parties with respect to health care items and services (SSA § 1902(a)(25)). Medicaid is the payer of last resort and providers are to identify and refund overpayments received. We will determine if States have taken action to ensure that Medicaid is the payer of last resort by identifying whether a third-party payer exists and if the State correctly reports the third-party liability to Centers for Medicare & Medicaid Services.
