Settlement paperwork: releases, liens and Medicare reimbursement

Signing a settlement release ends your right to claim more money for that crash from the people it names, usually for good and often for injuries you have not discovered yet. It does not erase the debts the crash created: hospitals, health plans, Medicare, Medicaid and sometimes your own auto insurer can all claim part of the money, and some of those claims come out of the settlement before you see it. The few pages of paperwork decide how much you keep, so read them before the check does the talking.

What a release gives up

A release is a contract. In exchange for payment, you promise not to pursue the claim further. Three versions show up in car-accident cases, and they differ sharply.

A general release is the default form many insurers send. It is not a trap, but it is complete: if you later learn the injury is worse than the first X-ray showed, the release usually prevents you from seeking more. The rules on cashing a check that comes with release language are in Does cashing a claim check end your claim? Releases explained. Everything below assumes a release for an injury claim.

Claims against other parties

Many releases name only the at-fault driver and the driver's insurer, but some add "all other persons, firms and corporations." That phrase can reach an employer, the owner of the car, a bar that served the driver, or a government agency, if you ever had a claim against them. Before you sign, ask who else might be responsible and whether the release should carve them out. Some releases name the settling party and expressly reserve claims against others; that is the language to look for if more than one party shares fault.

Your own coverage

If the at-fault driver's policy pays out its limit and you also carry underinsured motorist coverage, signing a general release without your insurer's consent can cost you that claim. The usual path is a limited release, plus written consent from your own insurer. The sequence is described in uninsured motorist claims: consent to settle, arbitration and proof and underinsured motorist claims: offset vs excess and consent to settle.

Clauses worth slowing down for

Read the whole release. These provisions turn up often and do real work:

• Unknown claims. Language that covers "known and unknown injuries, whether or not now manifest" is the point of a general release. You are accepting the risk that the injury changes.
• Indemnity or hold-harmless. You promise to pay any liens or reimbursement claims out of the settlement, and to cover the other side if a lienholder pursues them. This is why unresolved liens are your problem even after the check clears.
• Medicare language. Many releases contain representations about whether you are a Medicare beneficiary and who is responsible for repayment. The reason is in the Medicare section below.
• Confidentiality. A promise not to discuss the amount or the dispute, sometimes with a penalty for breaking it.
• No admission of liability. Standard. It protects the payer; it does not affect your recovery.
• Dismissal with prejudice. If a lawsuit is pending, the case ends and cannot be refiled.
• Who signs. Everyone with a claim from the crash, which may include a spouse with a loss-of-consortium claim.

A demand letter sets the settlement amount; the release sets what you are giving up for it. They are separate documents, and the second one is where terms the negotiation never mentioned can appear.

Who can claim part of the money

A settlement is one pot of money with several possible claimants. Each claimant has its own legal basis, and each has its own rules for how much it can take.

Hospital liens

A hospital lien is a legal claim against your recovery, not against you personally. State statutes vary in who can file one, how much it can take, and what notice is required. As an example, California's Hospital Lien Act, as FindLaw reproduces Civil Code 3045.4, limits the hospital's recovery to 50 percent of the money due "after paying any prior liens," and limits the liability to the amount claimed in the notice and no more than the hospital was entitled to receive for the care. Another state's statute may differ on every one of those points. Verify the current text with the state legislature or an attorney.

Health plan reimbursement

If your health insurance paid crash-related bills, the plan may ask to be repaid from the settlement. The Supreme Court addressed the strength of that clause in US Airways, Inc. v. McCutchen, decided April 16, 2013: in a suit under ERISA to enforce a plan's reimbursement term, "the terms of the ERISA plan govern," so equitable doctrines such as the common-fund rule cannot override a clear plan provision, though they can fill gaps where the plan is silent about attorney's fees (Cornell LII summary). In practice, the plan document matters, and whether it is an employer-sponsored ERISA plan matters. Ask for the full document, not a summary letter.

Your own MedPay or PIP

Medical payments and PIP benefits are paid regardless of fault. Whether your insurer can recover those payments from a settlement with the at-fault driver depends on your policy and state law. Ask your insurer in writing before you settle. The broader picture of who pays first is in who pays your medical bills after a car accident.

Medicare: the claim that cannot be ignored

Medicare covers treatment, and federal law then makes the money you recover from a car accident the first source of repayment. The statute says Medicare may not pay to the extent that payment "has been made, or can reasonably be expected to be made" under an automobile or liability insurance policy, a self-insured plan or no-fault insurance, and that when Medicare pays anyway as a "conditional payment," the primary plan "and an entity that receives payment from a primary plan" must reimburse the Medicare trust fund (42 U.S.C. 1395y(b)(2)). That reaches the settling insurer and also the person who received the money. The statute lets the United States recover from "any entity that has received payment from a primary plan or from the proceeds of a primary plan's payment to any entity," and sets double damages against a primary plan that fails to reimburse. If reimbursement is not made within 60 days after notice, Medicare may charge interest.

Why the insurer asks for your Medicare status

Under the same statute, a liability insurer, including a self-insured company, must determine whether a claimant is entitled to Medicare benefits and report to the government, after the claim is resolved "through a settlement, judgment, award, or other payment (regardless of whether or not there is a determination or admission of liability)." CMS's reporting threshold for physical-trauma liability settlements was $750 as of January 1, 2025 (CMS NGHP User Guide, October 2025). So an adjuster asking for your Medicare number or date of birth is meeting a federal requirement, and a refusal to answer can stall the settlement.

How Medicare's repayment is calculated

CMS deals with the claimant, or the claimant's lawyer, through the Benefits Coordination & Recovery Center. Medicare's initial conditional-payment amounts are interim figures; a formal demand follows the settlement. CMS lays out three ways to get a number, at its Demand Calculation Options page:

1. Final conditional payment process. For liability cases, you or your representative can tell the center you are within 120 days of settling, get a time-stamped final amount, and settle within 3 business days of requesting it. It can be started only once per case, and missing a step voids it.
2. Self-calculated amount. Available only in liability cases where the injury was caused by physical trauma, treatment ended at least 90 days earlier, the incident was at least six months ago and the total settlement is $25,000 or less. You give up the right to appeal the amount or existence of the debt, though you keep the right to seek a waiver.
3. Fixed percentage option. For physical-trauma liability settlements at or below a CMS-set ceiling. The page lists the ceiling as $5,000, rising to $10,000 effective October 2, 2023. CMS also says to elect it before Medicare has issued a demand.

CMS reduces its claim to account for the cost of getting the settlement. Under 42 CFR 411.37, when Medicare's payments are less than the settlement, you take the ratio of procurement costs (typically legal fees and case costs) to the total settlement, apply it to Medicare's payments, and subtract the result from Medicare's payments.

A worked example with invented numbers

Say Helen, 71, settles a car-accident injury claim for $60,000. Her attorney's fee and case costs together come to $20,000. Medicare paid $18,000 in conditional payments for crash-related care.

• The ratio of procurement costs to settlement is $20,000 / $60,000, or one-third.
• Medicare's share of those costs is one-third of $18,000, which is $6,000.
• Medicare's recovery is $18,000 minus $6,000, or $12,000.

Helen's remaining money after fees, costs and the Medicare repayment is $60,000 − $20,000 − $12,000 = $28,000, before any other lien. The numbers are hypothetical, and the actual process runs through CMS's forms and portal. More on how Medicare treats auto medical bills before settlement is in medicare and car accident medical bills: who pays first.

Medicaid recovery

Medicaid is also entitled to reimbursement, but the legal limits are different. A federal law requires states to take reasonable steps to find liable third parties and seek reimbursement for care they paid (42 U.S.C. 1396a(a)(25)). In Arkansas Department of Health and Human Services v. Ahlborn (2006), a case that began with a car accident, the Supreme Court held that the state could not assert a lien on the settlement beyond the portion that represented medical expenses (Cornell LII). In Gallardo v. Marstiller, decided June 6, 2022, the Court held that the Medicaid Act permits a state to seek reimbursement from settlement payments allocated for future medical care as well (Cornell LII).

The practical lesson is that how a settlement is described matters. State laws and court procedures on allocating the settlement, and on challenging a state's claimed amount, differ. If you or a family member receives Medicaid, ask the attorney or the state agency, before signing, how the state's claim is calculated.

Where the money goes: a net-to-you example

Fees, costs and liens are paid from the settlement, usually through a lawyer's trust account, and you receive what is left. Say Omar, who is not on Medicare, settles his injury claim for $75,000. The lawyer takes a one-third fee ($25,000) and was reimbursed $3,000 in case costs. A hospital lien of $9,000 is negotiated to $6,000, and his health plan agrees to accept $5,500 on an $8,000 claim.

Notice that Omar's net depends heavily on the lien negotiations. The order in which claims are paid is set by state statute, by the lien documents and, for Medicare, by federal law. It is not set by whoever asks first. A written disbursement statement should list every deduction before you sign it. The reasons an attorney can matter at this stage, and how fees work, are in when to hire a lawyer after a car accident.

Minors and structured payments

Releases signed by or for a child, or involving a person who lacks legal capacity, are often subject to court approval. New York's CPLR 1207 shows the pattern: on motion by a guardian or parent, "the court may order settlement of any action commenced by or on behalf of the infant" (CPLR 1207). Other states have their own rules about who files, whether a hearing is required, and where the money is held until the child is an adult. A parent who signs on the child's behalf without the required approval may not bind the child.

A structured settlement pays part of the settlement over time through an annuity instead of a lump sum. It changes the paperwork: there is usually a qualified assignment, a separate purchase agreement, and a schedule of payments that typically cannot be changed later without court involvement. Think about whether you may need cash for medical care before agreeing to defer it.

Taxes

Federal law excludes from gross income "the amount of any damages (other than punitive damages) received (whether by suit or agreement and whether as lump sums or as periodic payments) on account of personal physical injuries or physical sickness" (26 U.S.C. 104(a)(2)). The statute makes an exception for amounts attributable to medical expense deductions taken in an earlier year, which is why a person who deducted crash-related medical costs should tell a tax professional. Punitive damages, which the statute carves out, and damages that do not arise from physical injury are treated differently. State tax rules vary too. Ask a tax professional about your own case before the money arrives.

A checklist before you sign

1. Identify what you are releasing. Name each person and company covered, and each claim.
2. Confirm your medical condition is stable or that you understand you are releasing future problems.
3. List every lien and reimbursement claim in writing: hospital, health plan, Medicare, Medicaid, MedPay or PIP, workers' compensation.
4. Get Medicare's amount through the process above if you are a beneficiary or have been eligible.
5. Check your own coverage. If underinsured motorist coverage might apply, get your insurer's written consent first.
6. Read the indemnity and confidentiality clauses.
7. Ask for a written closing statement showing the gross amount, fees, costs and every payment to a third party.
8. Ask how and when the check will be issued, to whom, and when funds can be released from the trust account.
9. Keep copies of the release, the closing statement and every lien payoff letter.
10. Do not sign under a deadline you cannot verify. A time limit in an offer letter is a negotiating tool; the real deadline is the statute of limitations, which varies by state.

Common questions

Can I settle and then get more if my injury gets worse?

Not after signing a general release. That is the risk the release shifts to you. If your recovery is uncertain, ask whether the claim should wait for a clearer medical picture.

Does Medicare have to approve my settlement?

For liability settlements, Medicare does not approve the amount. It asserts a claim for repayment of what it paid, and the federal statute gives it recovery rights against the proceeds. Your settlement can proceed, but ignoring the claim risks interest and recovery action. The statute states that an action to recover cannot be filed more than 3 years after the date of notice of the settlement.

What if I don't know about any liens?

Ask each provider, your health plan and Medicare. The indemnity clause in the release usually makes you responsible for liens you did not mention. A lawyer can run a lien search, and insurers sometimes ask the claimant to certify there are none.

Who decides how a minor's settlement is divided?

A court usually reviews and approves it, as in the New York example. The rules differ by state, so ask the court clerk or an attorney in your state.

Key takeaways

• A release ends claims against the people it names, including unknown injuries; a limited release can preserve your underinsured motorist claim, but you need your insurer's consent.
• Hospitals, health plans, Medicare, Medicaid and your own insurer can each claim part of the settlement, and the net to you depends on those negotiations.
• Medicare must be repaid from liability settlements; CMS offers a final conditional payment process, a self-calculated option under $25,000, and a fixed-percentage option for small settlements.
• Medicaid's recovery is limited to the medical portion of a settlement, but that includes future medical care.
• Get a written closing statement and check every clause before you sign, and use a licensed attorney or your state insurance department for state-specific questions.
