Third-Party Liability (TLP)

Third-party liability (TPL) is when the financial responsibility for all or part of a member's health care expenses rests with an individual entity or program (e.g., Medicare, commercial insurance) other than AmeriHealth Caritas Pennsylvania.

Coordination of benefits (COB) is a process that establishes the order of payment when an individual is covered by more than one insurance carrier. AmeriHealth Caritas Pennsylvania is always the payer of last resort. This means that all other insurance carriers (the “primary insurers”) must consider the health care provider’s charges before a claim is submitted to AmeriHealth Caritas Pennsylvania.

Please refer to the Claims Filing instructions (PDF) for more specific information, including submitting TPL claims and COB/secondary claims.
