Subrogation

Legally Reviewed by Frank P. Marsalisi on September 11, 2026

Subrogation is the legal right that allows an insurance company or health plan that paid your medical bills after an accident to seek reimbursement from any settlement or award you later recover from the at-fault party. In plain terms, if your health insurer covered your treatment after a car accident, it may be entitled to be paid back once you settle your claim.

One of the more confusing parts of any personal injury case is the legal jargon that gets used along the way, and subrogation is one of the terms that trips up the most people. At Marsalisi Law, we walk clients through exactly how subrogation and collateral sources work so there are no surprises once a settlement is finally reached.

What Is Subrogation?

Subrogation refers to the right of one party, most often a health insurance company, to step into your shoes and seek reimbursement from a third party responsible for an expense it already paid on your behalf. In a personal injury context, this typically happens when your health insurer pays for treatment related to an accident that was someone else’s fault. Because the law generally does not allow you to be compensated twice for the same medical expenses, once by your insurer and again by the at-fault party, the insurer that already paid may assert a right to be reimbursed out of your eventual settlement or judgment.

What Is a Collateral Source?

A collateral source is any third party that pays part of your accident-related expenses independent of the party who caused your injury. Common examples of collateral sources in a Florida personal injury claim include:

• Health insurance, which is the most frequent source of subrogation claims after an accident.
• Medical payments coverage, sometimes called MedPay, on your own auto insurance policy.
• Personal Injury Protection, or PIP, benefits paid under Florida’s no-fault insurance system.
• Workers’ compensation benefits, if the accident happened while you were on the job.
• Medicare or Medicaid, which have their own distinct reimbursement rules under federal and state law.

Each of these sources may have a different process for asserting a subrogation or reimbursement claim, and some are governed by federal law rather than Florida’s collateral source statute alone. Sorting out which sources are involved in your case, and what each one is actually entitled to recover, is often one of the more time-consuming parts of resolving a claim that involves significant medical treatment.

How Subrogation Affects a Florida Personal Injury Claim

To see how this plays out in practice, consider a typical car accident fact pattern. You are injured in a car accident, and the at-fault driver only carries $10,000 in bodily injury liability coverage. In the meantime, your own auto insurer has already paid some of your medical bills through your Personal Injury Protection, or PIP, coverage, which is primary for accident-related injuries in Florida. Your health insurance carrier has also paid a portion of your treatment costs beyond what PIP covered.

Before you can finalize a settlement with the at-fault driver’s insurer, you need to know what portion of that settlement your health insurance carrier may be entitled to recover under its subrogation rights. Skipping this step can leave you owing money back out of a settlement you believed was already final, which is one of several reasons experienced legal guidance matters in claims involving multiple insurers.

Florida’s Collateral Source Statute

Florida law directly addresses how collateral sources and subrogation interact with a personal injury award. Under Section 768.76, Florida Statutes, when a court awards damages in a personal injury case, it generally must reduce that award by the amount already paid by collateral sources, except to the extent that a collateral source provider holds a valid right of subrogation or reimbursement. The statute also requires a collateral source provider to respond to a request for its subrogation lien amount within a set time period, and a provider that fails to do so within that window may waive its right to reimbursement altogether.

This framework is designed to prevent a plaintiff from recovering the same medical expenses twice, once from a collateral source and again from the at-fault party, while also giving injured parties and their attorneys a defined process for resolving competing claims to the same settlement funds.

Because the statute ties a provider’s right of reimbursement to whether it responded to a request for its lien amount within the required window, the timing of these requests matters. An attorney handling your claim typically sends this request early in the case so there is time to review, and if necessary dispute, the amount a collateral source provider claims to be owed well before a settlement is finalized.

Why Subrogation Matters More in Serious Injury Cases

The more extensive your medical treatment, the more collateral source payments are typically involved, and the more significant a subrogation claim can become. A relatively minor accident with a few urgent care visits may involve a modest reimbursement request, while a serious accident requiring surgery, hospitalization, and months of physical therapy can generate a health insurance subrogation lien worth tens of thousands of dollars. In cases involving limited insurance coverage from the at-fault driver, understanding exactly how much of a settlement will go toward reimbursing a collateral source, rather than to you, can materially affect whether a settlement offer is actually adequate for your losses.

This is part of why subrogation should be evaluated early rather than treated as an afterthought once a settlement number is already on the table. A settlement that looks reasonable before subrogation is accounted for can look very different once a lien is factored in.

How to Protect Your Settlement From Subrogation Issues

An attorney handling a claim involving subrogation typically takes several steps to make sure a collateral source’s reimbursement claim is accurate and properly reduced before any funds are disbursed. This can include requesting a certified copy of the health plan’s policy to determine whether a genuine right of subrogation exists in the first place, identifying and removing any charges unrelated to the accident from the lien amount, and negotiating reductions in the lien to account for attorney’s fees and costs associated with obtaining the recovery. Because every health plan and every claim is different, the amount ultimately owed back to a collateral source can vary significantly from case to case.

It is also worth understanding how subrogation interacts with an early settlement offer. Accepting an offer before your subrogation obligations are known can leave you with less than you expected once a lien is resolved, which is one more reason to have any offer reviewed before you sign a release.
