T
Definition
The legal obligation of third parties (e.g., private health insurance, auto insurance, workers' compensation) to pay part or all of the expenditures for medical assistance furnished under a Medicaid plan.
Overview
Why it Matters
Medicaid is the "Payer of Last Resort." If a member was in a car accident, the Auto Insurance should pay for the transport to therapy, not Medicaid.
How it Works
Before billing Medicaid, the provider/biller must check if the member has other insurance. If so, they must bill that insurer first. Medicaid only pays the remainder (if any).
Code Comparison
Comparison: TPL vs. Co-Pay
TPL: Another insurer pays.
Co-Pay: The patient pays.
Common Questions
- Billing Medicaid First: Submitting a claim to Medicaid for a Workers Comp case. Medicaid will pay it initially but will "claw back" the money 2 years later when they find out, wrecking your finances.
- Medicare Crossovers: Failing to understand that Medicare doesn't cover routine NEMT, so the "TPL Denial" from Medicare is often just a formality needed to bill Medicaid.
- Ask "Is this trip related to an accident at work or in a car?" during intake.
