What Is Subrogation? The Word That Decides What You Actually Keep

Most injured people never hear the word subrogation until it costs them money.

It's the reason a settlement number and a take-home number can be very different, and it's one of the least-explained parts of a personal injury case. So here it is, in plain language.

What is subrogation?

Subrogation is the right of someone who paid your medical bills to be reimbursed out of your settlement.

If your health insurance, Medicare, Medicaid, or your auto PIP coverage paid for treatment after your injury, they generally didn't do it as a favor. They covered those costs with the expectation that if you later recover money from whoever caused the injury, they get paid back.

In legal terms, they "step into your shoes" — they take on your right to be reimbursed for those medical expenses. When settlement money arrives, they're in line ahead of you.

How is that different from a lien or a provider balance?

These terms get used interchangeably, and they aren't the same thing. The distinction matters because each is reduced in a different way.

Subrogation claim. Someone already paid, and wants to be reimbursed. A health plan, Medicare, Medicaid, PIP carrier.

Provider balance. Someone was never paid at all and is still owed. A doctor or facility that treated you without payment.

Letter of protection (LOP). A written promise that a provider will be paid out of your eventual settlement. Common when a person has no health insurance. These balances are often billed at full rate rather than a negotiated insurance rate, which makes them sizable — and makes reducing them consequential.

Hospital lien. A statutory or ordinance-based claim by a hospital against your recovery, filed in the public record.

A serious case commonly involves several of these at once.

Who can assert subrogation in Florida?

Private health insurance. Most plans include a subrogation or reimbursement provision. Whether and how much it can recover depends heavily on the plan's structure — self-funded ERISA plans, for example, operate under different rules than fully insured plans, and the difference can be substantial.

Medicare. Under the Medicare Secondary Payer Act, Medicare has a right to recover "conditional payments" — amounts it paid that should have been the responsibility of a liability insurer. Medicare's process is procedural and unforgiving about timelines.

Medicaid. Florida asserts Medicaid reimbursement rights under Florida Statute § 409.910, which sets a presumptive formula: the state is entitled to half the total recovery after deducting 25% for attorney's fees and costs — roughly 37.5% of the gross settlement — as the presumed portion representing past and future medical expenses.

That presumption can be challenged. A claimant may rebut it by showing, by clear and convincing evidence, that the portion of the recovery properly allocated to medical expenses is less than the formula produces.

Note for Florida specifically: in Gallardo v. Marstiller, 596 U.S. ___ (2022), the U.S. Supreme Court held that Florida may seek reimbursement from settlement amounts allocated to future medical care, not only past care. That decision expanded what Florida Medicaid can reach and makes early, careful handling of Medicaid cases considerably more important.

Your own PIP carrier, in certain circumstances.

Workers' compensation, where the injury is also work-related.

Why this can consume an entire settlement

Consider a straightforward scenario. Someone is seriously injured by a driver carrying minimum liability coverage. There are several injured claimants, so that limited policy is divided among them.

The injured person's share is a fraction of their actual losses — and every claim against it is fully intact. Health plan subrogation. Provider balances. An LOP billed at full rate. Possibly a hospital lien.

Added together, those claims can exceed the settlement itself. Which means the injured person — the one who was actually hurt — can end up with nothing, or close to it, from a settlement that looks respectable on paper.

This is why gross settlement figures are a poor measure of how a case went. The number that matters is what reaches the client.

What a lawyer is supposed to do about it

The case doesn't end at the settlement. A significant portion of the work happens afterward.

Identify every claim. Claims that surface after disbursement are a serious problem. They have to be found first.

Verify each one is actually valid and correctly calculated. Subrogation claims routinely include charges unrelated to the incident. Medicare conditional payment summaries frequently contain treatment for unrelated conditions. These need to be audited line by line, not accepted at face value.

Negotiate reductions under the right framework. This is where experience shows. ERISA plan claims, Medicare conditional payments, Medicaid interests under § 409.910, hospital liens, and LOP balances each have distinct legal and practical bases for reduction. Treating them as one undifferentiated pile leaves money on the table — the client's money.

Account for attorney's fees and costs in the allocation. Several frameworks reduce the claim proportionally to reflect the fact that the lawyer's work is what created the recovery at all.

Document everything. So the client knows precisely where every dollar went.

What you should ask your lawyer

If you're deciding who to hire, or you have an active case, these are fair questions:

• "What is my estimated net recovery, not the gross?"
• "What subrogation claims and liens exist, and who is asserting them?"
• "How will you try to reduce each one?"
• "Will I see an itemized disbursement statement before I sign anything?"

Any competent lawyer will answer all four without hesitation. If someone can't or won't, that tells you something.

The short version

Your settlement isn't your money until the claims against it are resolved. Subrogation is the largest and least understood of those claims. And what your lawyer does after the settlement can matter as much as what they negotiated before it.
