Third Party Liability
Federal regulations require Medicaid to be the "payer of last resort". This means that all third party insurance carriers, inculding Medicare and private health insurance carriers, must be billed before Medicaid processes the claim. Additionally, Providers must report any payments from third parties on claims filed for Medicaid payment.
