9.1.1 Third Party Liability Introduction

TPLThird Party Liability. The obligation a third party (not Wisconsin Medicaid or the Medicaid member) has to pay the bills for a Medicaid member’s medical services. refers to the obligation a third party (not Wisconsin Medicaid program or the Medicaid memberA recipient of Medicaid; formerly referred to as a "client."), has to pay the bills for a Medicaid member’s medical services. Medicaid is the payer of last resort for the cost of medical care. This means that if a Medicaid member also has coverage under a private health insurance plan, that plan is to be billed first for any medical services. Medicaid then pays any amount remaining after the private insurer has paid what they owe, up to the Medicaid reimbursement rate. Another common example of TPL is when someone receives an insurance settlement resulting from an accident. If Medicaid paid for any medical services resulting from that accident, the Medicaid program is to be reimbursed the cost of those medical services from the proceeds of the insurance settlement. Third party payers include health insurers, court ordered medical support, and any other third party that has a legal obligation to pay for medical services.

9.1.2 Third Party Liability Cooperation

A member complies with this requirement by signing the application form. The assignment includes all unpaid medical support and all ongoing medical support obligations for as long as Medicaid is received. In addition, Medicaid members must cooperate in identifying and providing information to assist the State in pursuing third parties who may be liable to pay for care and services, unless the individual establishes good cause for not cooperating. If a member fails to cooperate with TPL requirements, they could be sanctioned.
