If you have Medicare and you’ve been in a car accident, your auto insurance pays first. Medicare and auto accidents intersect under a set of federal “secondary payer” rules: Medicare covers eligible costs only after your Personal Injury Protection, MedPay, or the at-fault driver’s liability insurance has paid or denied the claim, and any amount Medicare does pay in the meantime has to be paid back out of your settlement.
Why Auto Insurance Pays Before Medicare
Federal law makes Medicare a secondary payer whenever another insurance source could reasonably cover your bills. The Medicare Secondary Payer rules exist to keep costs on private insurers rather than the Medicare Trust Fund.1Centers for Medicare & Medicaid Services. Medicare Secondary Payer Overview Federal law overrides any state law or private insurance contract that tries to make Medicare pay first, so even if your auto policy says otherwise, Medicare’s secondary status holds.
Which auto coverage pays depends on your policy and who caused the crash. Two coverages pay regardless of fault. Personal Injury Protection (PIP), required in no-fault states, typically covers medical expenses and sometimes lost wages. Medical Payments coverage (MedPay), optional in most states, covers medical and funeral costs. Both pay up to their policy limits before Medicare contributes.
If another driver caused the accident, their liability insurance is the primary payer for your medical bills.2Centers for Medicare & Medicaid Services. Medicare Secondary Payer (MSP) Liability Insurance, No-Fault Insurance and Workers Compensation Recovery Process That includes self-insured businesses. Medicare picks up eligible remaining costs under its normal rules, including deductibles and coinsurance, only after those primary sources have paid or denied coverage.
Conditional Payments While Your Claim Is Pending
Auto claims can take months or years to resolve. If the primary insurer hasn’t paid and you need care now, Medicare can make a “conditional payment” so you’re not stuck out of pocket while you wait.3Office of the Law Revision Counsel. 42 US Code 1395y – Exclusions From Coverage and Medicare as Secondary Payer The word conditional is doing real work. Medicare is lending you the coverage, and every dollar has to be repaid once the primary insurer settles, pays a judgment, or otherwise pays out on the claim.
This is where people get caught off guard. You get treated, Medicare pays, life moves on, and then a settlement check arrives followed by a letter demanding repayment of everything Medicare covered. If you’ve already spent the money, you still owe it. The obligation to reimburse Medicare within 60 days of receiving a primary payment is written into federal regulation.4eCFR. 42 CFR 411.24 – Recovery of Conditional Payments
Reporting the Accident to Medicare
You’re required to notify Medicare whenever you make a claim involving liability insurance, no-fault insurance, or any other coverage that could pay for care Medicare also covered.5Centers for Medicare & Medicaid Services. Reporting a Case You can do it through the Medicare Secondary Payer Recovery Portal (MSPRP) or by calling the Benefits Coordination & Recovery Center (BCRC) at 1-855-798-2627.6Centers for Medicare & Medicaid Services. Medicare Secondary Payer Recovery Portal
Have ready:
- Your full name, Medicare number, date of birth, gender, address, and phone number
- The date of the accident and a description of your injuries
- Whether the claim involves liability insurance, no-fault insurance, or another source
- The name and address of the insurance company involved
Once the BCRC has the report, it posts the information to Medicare’s records and starts tracking any conditional payments tied to the accident. If you have an attorney on the accident claim, they can report and manage the case for you through the portal.
What Happens After You Settle
Once your case is reported, Medicare follows a set sequence to recover its money.7Centers for Medicare & Medicaid Services. Medicare’s Recovery Process
- A Rights and Responsibilities letter arrives first, explaining Medicare’s recovery rights and yours.
- Within about 65 days, the BCRC sends a Conditional Payment Letter listing every payment it believes is related to the accident, along with a Payment Summary Form.
- If items on the list aren’t accident-related, you can dispute them with documentation. The BCRC takes about 45 calendar days to review disputes.
- After your case settles, the BCRC issues a formal demand letter with the exact amount owed. Payment is due within 60 days.8Centers for Medicare & Medicaid Services. Conditional Payment Letters and Notices – Beneficiary
If you report the case only after settling, the BCRC skips ahead and issues a Conditional Payment Notification. You then have only 30 calendar days to raise disputes. Miss that window and the BCRC issues a demand for the full amount, with no reduction for attorney fees or costs. Reporting before you settle gives you far more room to review and challenge charges.
How Attorney Fees Reduce What You Owe
When Medicare sends its demand directly to a beneficiary, it factors in reasonable “procurement costs,” meaning attorney fees and litigation expenses paid to get the settlement.9Centers for Medicare & Medicaid Services. Reimbursing Medicare Medicare’s recovery is reduced by the same proportion your legal costs bear to the total settlement.10eCFR. 42 CFR 411.37 – Amount of Medicare Recovery When a Primary Payment Is Made
If attorney fees and costs consumed 40% of your settlement, Medicare reduces its claim by 40%. On $10,000 in conditional payments, the demand drops to $6,000. The reduction depends on responding on time and documenting your legal costs. Missing the 30-day window on a post-settlement notification means Medicare demands the full amount.
What Happens If You Miss the Deadline
Once the demand letter is out, you have 60 days to pay. Miss that and interest starts accruing back to the date the demand letter was issued, not from the day you missed the deadline.8Centers for Medicare & Medicaid Services. Conditional Payment Letters and Notices – Beneficiary Two months of interest can land on you the moment the clock runs out.
If the debt still isn’t resolved, the BCRC can refer it to the Department of the Treasury for collection, including offset against tax refunds and other federal payments, and to the Department of Justice for legal action.7Centers for Medicare & Medicaid Services. Medicare’s Recovery Process Referral to Treasury’s offset program typically goes out within 150 days of the original demand letter if you haven’t paid or raised a valid defense.
Insurers face a sharper tool. Federal law gives the government a private cause of action for double the amount owed against a primary payer that fails to reimburse Medicare.3Office of the Law Revision Counsel. 42 US Code 1395y – Exclusions From Coverage and Medicare as Secondary Payer The provision also reaches anyone who received proceeds from the primary payment, which can include beneficiaries holding settlement funds.
If You Can’t Pay the Full Amount
If the demand looks wrong or paying it would create real hardship, you have options beyond disputing individual charges.
Compromise
A compromise is an offer for Medicare to accept less than the full amount. You submit the request in writing to the BCRC after settlement and after providing settlement details.11Benefits Coordination and Recovery Center. Submit Compromise Request (What Is This?) One catch worth knowing: CMS’s compromise decision is final and cannot be appealed. Rejecting a compromise offer leaves a waiver as your remaining path.
Waiver
Medicare may waive recovery entirely if two things are true: you were not at fault for Medicare making the conditional payments, and repaying the money would cause financial hardship or would be unfair for another reason.12Benefits Coordination and Recovery Center. Submit Waiver Request (What Is This?) You apply using SSA Form 632 (Request for Waiver of Overpayment Recovery) with documentation supporting your hardship claim.13Social Security Administration. Form SSA-632 – Request For Waiver Of Overpayment Recovery Waivers are harder to win than compromises because you have to show both no fault and genuine burden.
Medicare Advantage Works Differently
If you have Medicare Advantage (Part C) instead of Original Medicare, the recovery process changes. Medicare Advantage plans are private insurers and generally don’t use the BCRC. They run their own subrogation departments and pursue reimbursement directly from you or the at-fault party’s insurer.
The underlying legal authority is the same. Federal regulations give Medicare Advantage plans the same recovery rights CMS has under the MSP rules.1Centers for Medicare & Medicaid Services. Medicare Secondary Payer Overview Some plans have pursued double damages under the MSP Act’s private cause of action, though courts have split on whether that remedy is available to private insurers. If you have Medicare Advantage and are in an accident, contact your plan directly. Don’t assume the BCRC process applies, and don’t assume the plan will pursue less aggressively than Original Medicare.
Future Medical Costs in Your Settlement
Medicare’s interest doesn’t end with conditional payments for past care. If your settlement includes money for future medical expenses Medicare would otherwise cover, you’re expected to spend those funds on that care before billing Medicare.
In workers’ compensation cases, CMS has a formal review process for Medicare Set-Asides. For liability cases like auto accidents, no statute or regulation formally requires a Liability Medicare Set-Aside, and CMS has no formal review threshold. But CMS has consistently maintained that Medicare’s interests must be considered in any liability settlement. Ignoring future medical costs can result in Medicare later refusing to pay for accident-related care. Concern often centers on settlements over $25,000 with a significant portion allocated to future medical expenses, and on cases where the injured person is already on Medicare or will be soon.
If your settlement involves substantial future medical costs, address Medicare’s interest with your attorney before finalizing the deal. Unwinding a completed settlement to satisfy Medicare is rarely practical.
