Quick answer: A medical lien, or reimbursement claim, is a legal claim on part of your settlement for medical bills that someone else paid or is owed. Hospitals can have liens under some state laws, health plans claim reimbursement under their terms, and Medicare and Medicaid have federal and state recovery rights. These claims are paid out of your settlement, but the rules often limit them, and the limits depend on the state and the kind of claimant.

What a lien or reimbursement claim is

When someone else pays your medical bills after an accident, they often want to be repaid if you later recover money from the person responsible. A medical lien is the legal claim that lets them take a share of your settlement. Related terms are reimbursement, where a plan's contract says you must pay it back, and subrogation, the process in which one party assumes another's legal rights; the Legal Information Institute's example is an insurer that compensates its policyholder and takes over the policyholder's right to recover from the person responsible.

These claims are paid out of your settlement, which is why they can shrink the check significantly. How the pieces fit is in how a settlement is calculated.

Who can claim part of your settlement

ClaimantWhere the right comes fromHow it can be limited
MedicareFederal Medicare Secondary Payer lawReduced by its share of procurement costs
MedicaidState law, within federal limitsOnly the part of the settlement that represents medical expenses
Hospitals and providersState lien statutes, where they existStatutory caps, which differ by state
Health plansThe plan's reimbursement terms, and state lawDepends on the plan and the state

Medicare

Federal law lets Medicare recover payments it made conditionally when another party is responsible for the bills; see the Medicare Secondary Payer statute. The regulations then reduce Medicare's recovery for your cost of getting the settlement. When Medicare's payments are less than the settlement, you take the ratio of procurement costs to the total settlement and apply it to the Medicare payment, and subtract that share from what Medicare paid. For example, on a $100,000 settlement with $36,333 of fees and costs, a $15,000 Medicare payment shrinks to about $9,550.

Medicaid

State Medicaid programs also seek repayment, but federal law limits them. In Arkansas Department of Health and Human Services v. Ahlborn, the Supreme Court held that the State could not lay claim to more than the portion of the settlement that represents medical expenses, and could not reach the part that compensates for things like pain and suffering or lost wages. State rules on notice, fee sharing and reductions vary, which is what the Medical Lien Calculator covers for each state.

Hospitals and providers

A hospital or doctor has a lien on your settlement only where a state statute creates one, and the statutes differ widely. Two examples:

Health plans

Your health plan may claim reimbursement under its own terms. For many employer plans governed by the federal ERISA law, the Supreme Court held in US Airways v. McCutchen that where a plan creates a lien by agreement, the plan's terms govern, and general equitable principles such as the common-fund rule, which would make the plan share your legal fees, cannot override the contract. Plans that ERISA does not cover are subject to state law, which may follow different rules, so ask what kind of plan you have before assuming anything.

What to do about liens

  • List every claimant early. Ask each provider, plan and agency in writing for an itemized, accident-related amount, so a lien does not surprise you after you accept an offer. See what to check before you answer an offer.
  • Find out what limits apply. Caps, procurement-cost reductions and plan terms can change the amount, as shown above.
  • Look at your net. The Attorney Fee Calculator shows what you keep after fees, costs and liens.
  • Consider help for large or complicated liens. See whether you need a lawyer.

Frequently asked questions

What is a medical lien?

A legal claim on part of your injury settlement for medical bills that someone else paid or is owed. People also use the term for reimbursement and subrogation claims by insurers and government programs.

Who can claim part of my settlement?

Hospitals and other providers where a state lien law exists, health plans under their reimbursement terms, Medicare under federal law, and state Medicaid programs. Each has its own rules and limits.

Does Medicare reduce its claim for my attorney fees?

Yes. Under the Medicare regulations, when Medicare's payments are less than the settlement, its recovery is reduced by its share of procurement costs, computed from the ratio of those costs to the total settlement.

Can Medicaid take my whole settlement?

No. The U.S. Supreme Court held in Ahlborn that a state Medicaid agency may claim only the part of a settlement that represents medical expenses, not payment for pain and suffering or lost wages.

Does my health plan have to share my attorney fees?

It depends on the plan and the state. For an employer plan under ERISA with a reimbursement clause, the Supreme Court held in McCutchen that the plan's terms govern and general equitable rules cannot override them. Plans that ERISA does not cover are subject to state law, which may differ.
