Statute of limitations on medical debt

What it actually limits

A statute of limitations sets the period during which a creditor can file a lawsuit to collect. Once it has run, the debt does not vanish and is not cancelled. What changes is that the creditor loses the ability to obtain a judgment against you — and a judgment is what makes wage garnishment and bank levies possible.

Two things follow that people are routinely surprised by. The debt can still be reported, still be sold on, and still be asked for after the period ends. And the expiry is a defence you have to raise: if you are sued on a time-barred debt and do not appear, the court will not notice on your behalf and a default judgment can be entered anyway.

Why we do not publish a state-by-state table

Almost every site covering this topic prints a grid of fifty numbers. The grids disagree with one another, they go stale as legislatures amend the rules, and they gloss over the part that actually decides your case — which limitation period applies to your debt in the first place.

A state typically sets different periods for different kinds of obligation: a written contract, an open or unwritten account, an oral agreement, and sometimes a specific category for medical or hospital services. Whether an unpaid hospital bill is a written contract because you signed a financial responsibility form on admission, or an open account because it was billed as services accrued, is a genuine question that different states answer differently. The same bill can therefore sit under two different clocks depending on where you live.

Across the states the periods commonly fall somewhere in the range of three to six years, with shorter and longer outliers in both directions. That range is worth knowing as an order of magnitude and is worth nothing as a basis for a decision. For your own situation, check your state's own published rule — your state attorney general's consumer pages and your local legal aid organisation are the two places most likely to have it accurately and free.

When the clock starts

The start date matters as much as the length, and it also varies. Depending on the state, the period may run from the date of service, from the date the account became delinquent, or from the date of the last payment or last activity on the account.

That last variant carries a trap. In many states, making a payment on an old debt — even a small one — or acknowledging the debt in writing can restart the limitation period from zero. A collector calling about a debt that is nearly out of time has a clear incentive to obtain a token payment, and the person making it usually has no idea what it does.

If a debt is old enough that this might matter, the safe order is: find out what your state's rule is first, then decide whether to pay anything, and put nothing in writing that acknowledges the balance until you know.

What a collector may and may not do

Asking you to pay a time-barred debt is generally permitted. Suing on one, or threatening to sue on one, is a different matter — federal debt collection rules restrict misleading statements about a debt's legal status, and courts have treated threats of suit on time-barred debt as falling foul of them.

You also have a written dispute and validation right. Requesting validation in writing requires the collector to substantiate the debt before continuing to collect, and it produces a paper record of what they claim you owe and when it arose. On an old medical account, that record is often the fastest way to establish which dates are actually in play.

Credit reporting is a separate question

How long a debt can be sued on and how long it can appear on a credit report are two different clocks that people frequently merge into one. They are set by different bodies of law and they do not expire together.

The rules here are unsettled and being actively contested, so it is worth being precise about what is currently true. A federal rule that would have excluded medical debt from consumer credit reports was vacated by a court in July 2025. What remains is a voluntary policy adopted by the major credit bureaus — not law — under which certain medical collection accounts are not reported. A voluntary policy can be changed by the parties that adopted it. Alongside that, around fifteen states have enacted their own rules restricting medical debt reporting, and that patchwork is itself changing.

Do not rely on a summary of this, including this one, as current. If a medical collection appears on your report, check what your own state provides and check the position at the time you are reading, because it has moved more than once.

If you are sued

This is the part worth remembering above everything else on the page. Respond to the court papers. The most common way people lose these cases is by not appearing, which produces a default judgment regardless of how strong the limitation defence would have been.

Responding does not mean conceding, and it does not mean you need to have worked out the law first. It means filing an answer within the period stated on the papers and raising the limitation point if it applies. Free help with exactly this exists in most places through legal aid and court self-help services.
