## Quick answer

A conditional payment is a payment Medicare makes for medical care that another payer, such as the at-fault driver's liability insurer, may owe. Medicare pays so you can get care while the claim is pending. The condition is repayment: Medicare must be repaid its conditional payments when a settlement, judgment or award is paid.

## In a car accident claim

Medicare is a secondary payer when other insurance should pay for crash care. It also waits for no-fault coverage: Medicare does not pay until the beneficiary has used up their no-fault benefits. Once your claim is reported, Medicare's recovery contractor tracks what it paid. It sends a Conditional Payment Letter listing those payments within 65 days of its first letter, called the Rights and Responsibilities letter, and you can dispute charges unrelated to the crash.

After a settlement, Medicare issues a final demand. Interest is charged if the debt is not resolved 60 days after the demand letter. Medicare also grants a pro-rata reduction of the amount owed for your lawyer's fees and other costs of getting the settlement.

## Example

> **Example:** A retiree on Medicare is hurt in a crash, and Medicare pays for the hospital stay and follow-up visits. The retiree's claim against the at-fault driver settles. Before the money is paid out, the retiree's lawyer checks Medicare's list for unrelated charges, gets the final demand and repays Medicare from the settlement.

## FAQ

### Do I have to repay Medicare from a car accident settlement?

Yes, for conditional payments related to the crash. Federal rules require Medicare to be repaid when a settlement, judgment or award is paid, and the amount is reduced by a share of the legal fees and costs.

### Can Medicare's repayment amount be lowered?

After the demand letter, you can ask Medicare to waive recovery in full or in part, or appeal the demand. A waiver request is considered only after Medicare's recovery demand letter has been issued.
