Medical Debt Statute of Limitations

The statute of limitations on medical debt ranges from 2 to 10 years depending on your state. After that window closes, a creditor or collector loses the ability to sue you for the balance. Most states fall in the 3-to-6-year range. But the debt does not disappear, collectors can still ask you to pay, and making even a small payment can restart the clock in many states. The table below covers all 50 states plus DC.

How the Medical Debt Statute of Limitations Works

The statute of limitations is a deadline. Miss it (if you are the one suing) and the court throws out your case. For patients, this works in your favor: once the clock runs out on a medical bill, the hospital or collector can no longer take you to court to force payment.

Two things determine how long the clock runs.

First, how your state classifies medical debt. Most states sort debts into categories, each with its own time limit. The two that matter for medical bills are "written contract" and "open account" (sometimes called "oral contract" or "implied contract"). If you signed a financial responsibility form when you checked in for treatment (and most hospitals require one), your debt is typically classified as a written contract. If there was no signed agreement, it may fall under the shorter open-account period. The difference can be significant: in Georgia, that is 6 years versus 4. In Wyoming, 10 years versus 8.

Second, when the clock starts. In most states, the clock begins on the date of your last payment or the date the debt became delinquent. A few states use the date of service (New York, for hospital debt under CPLR 213-d) or the date the debt was referred to a collector (Florida, for hospital debt under HB 7089). The start date matters as much as the length.

What the SOL does: It bars lawsuits and creates an affirmative defense if you are sued. That is all. It does not erase the debt, does not stop collection calls, and does not remove the debt from your credit report (that is a separate 7-year clock under federal law).

One more complication: if you received treatment in one state but now live in another, the question of which state's SOL applies depends on where the lawsuit is filed, any choice-of-law provisions, and whether your state has a "borrowing statute" that applies the shorter of two time limits. If your situation involves multiple states, consult a consumer law attorney.

Medical Debt Statute of Limitations by State

This table covers all 50 states and the District of Columbia. The "SOL (Years)" column shows the period that typically applies to medical debt. Where two periods are listed, the applicable one depends on whether you signed a written financial agreement (see Notes). Statute citations link to the relevant state code.

What Restarts the Clock: The Revival Trap

This is the single most valuable warning in this article.

A debt collector calls about a $3,200 hospital bill from five years ago. The statute of limitations in your state is six years. The collector says: "Just pay $50 to show good faith. We can work something out." You send $50. The clock resets to zero. The collector now has six fresh years to sue you for the full balance.

This is not a hypothetical. It is a routine collection tactic. Collectors know that many patients have no idea a small payment can restart the legal deadline. (Source: NCLC, Limits on Collection of Time-Barred Debt)

In most states, two actions can restart (or even revive) the statute of limitations:

• Partial payment. Paying any amount on the debt, even $1, can restart the clock in the majority of states.
• Written acknowledgment. Signing a document that acknowledges you owe the debt (including a new payment plan agreement) can restart or revive the SOL. Some states require the acknowledgment to be signed; others accept oral statements.

The distinction between "restart" and "revive" matters. "Restart" means the clock resets while the SOL is still running. "Revive" means a payment or acknowledgment brings a dead claim back to life after the SOL has already expired. Some states allow both; some allow restart but not revival; and a growing number prohibit both.

States With Anti-Revival Protections

These states have enacted specific protections against the revival trap:

• New York (Consumer Credit Fairness Act, enacted 2021, effective April 2022): Once the 3-year SOL expires, no payment, acknowledgment, or other activity can revive it. (Source: CPLR 214-i)
• Arizona (Mertola, LLC v. Santos, 2018): The Arizona Supreme Court held that only a payment bringing the account fully up to date resets the SOL. A partial payment does not. (Source: Mertola, LLC v. Santos, 422 P.3d 1028 (Ariz. 2018))
• Minnesota (Debt Fairness Act, effective October 2024): Explicit anti-revival clause; partial payment, bankruptcy discharge, and reaffirmation do not restart the SOL. (Source: Minn. Stat. 541.053)
• District of Columbia (D.C. Law 24-154, effective January 2023): Once the 3-year SOL expires, any payment or affirmation "shall not extend the limitations period." (Source: DC Code 28-3814)
• Mississippi and Wisconsin: The SOL extinguishes the underlying right, not just the remedy. A time-barred debt cannot be sued on at all. (Source: Miss. Code Ann. 15-1-3; Wis. Stat. 893.05)
• Texas (HB 996, effective September 2019): Anti-revival protection for debts held by debt buyers only (companies that purchased the debt). This does not cover original creditors or traditional collection agencies. (Source: Tex. Fin. Code 392.307)
• California (CCP 360): No payment can revive an already-expired debt. Only a signed written acknowledgment can restart an active (not-yet-expired) SOL for most debt types. (Source: Cal. CCP 360)
• Maine, Maryland, Nevada: Explicit statutory provisions prevent post-expiration revival.

The bottom line: Never pay anything on old medical debt without first checking whether the statute of limitations has expired in your state and whether your state allows revival. If a collector asks you to "just pay a little" on debt that is close to or past the deadline, that request is not a favor. Get advice from a consumer attorney before making any payment.

What to Do If Sued on Time-Barred Debt

Under CFPB Regulation F (12 CFR 1006.26, effective November 30, 2021), third-party debt collectors are prohibited from suing or threatening to sue on time-barred debt. The CFPB's original rulemaking adopted a strict liability standard (the prohibition applies regardless of whether the collector knows the debt is time-barred), though the agency withdrew its advisory opinion reinforcing that interpretation in May 2025. The underlying regulation remains in force. (Source: 12 CFR 1006.26)

Important: This federal rule applies only to third-party collection agencies and debt buyers. It does not apply to hospitals or medical providers collecting their own debts. A hospital billing department that sues you on a time-barred debt is not violating Regulation F (though it may be violating state law). State consumer protection statutes may provide additional protections against original creditors. (Source: 15 USC 1692a(6))

Regardless of who is suing, one rule is absolute: you must respond to the lawsuit.

The statute of limitations is an affirmative defense. That means you have to raise it yourself. The court will not check the dates for you. The court will not dismiss the case on its own. If you ignore the summons and fail to file an answer, the court will enter a default judgment against you for the full amount claimed, even if the debt is clearly time-barred. That judgment is fully enforceable: wage garnishment, bank levies, property liens.

More than 70% of consumers sued in debt collection cases never respond. (Source: Pew Charitable Trusts) Every one of those default judgments is a win the creditor did not earn.

If you are served with a lawsuit for old medical debt:

1. Note the response deadline on the summons. You typically have 20-30 days.
2. File an answer with the court that includes the statute of limitations as an affirmative defense. State the date of last payment, the date of service, and your state's SOL period. Even a one-page answer prevents a default judgment.
3. If a third-party collector filed the suit, they may be violating Regulation F. That is both a defense and a potential counterclaim under the FDCPA.
4. Show up to any hearing. Just appearing gives you leverage.
5. Consult a consumer attorney if the amount is significant. Many take FDCPA cases on contingency. See our guide to finding legal help for medical debt.

Statute of Limitations vs. Credit Reporting: Two Different Clocks

Patients confuse these constantly, and the confusion is understandable. Both involve time limits. Both involve medical debt. But they are completely independent.

• Statute of limitations (state law, typically 2-10 years): Determines how long a creditor can sue you.
• Credit reporting period (federal law, 7 years): Determines how long the debt appears on your credit report. The clock starts approximately 180 days after the date you first became delinquent, per the Fair Credit Reporting Act. (Source: 15 USC 1681c(c)(1))

A debt can expire for lawsuit purposes while still sitting on your credit report. It can also fall off your report while the collector still has the right to sue.

One nuance that reinforces responding to lawsuits: under 15 USC 1681c(a)(2), civil judgments can be reported for 7 years from entry or until the governing statute of limitations expires, whichever is longer. If you let a default judgment be entered on a debt, the credit reporting period for that judgment may extend beyond the original 7-year window. (Source: 15 USC 1681c(a)(2))

The three major credit bureaus have voluntarily adopted policies that remove some medical collections: paid medical debt removed from reports (2022), medical collections under $500 excluded (April 2023), and a one-year waiting period before medical collections appear (July 2022). These are voluntary industry decisions, not legal requirements. A CFPB rule that would have gone further (finalized January 2025) was vacated by a federal court in July 2025.

Protect Yourself: What to Do Right Now

If you have old medical debt (or a collector is calling about one), work through this checklist:

• Find your state's SOL in the table above. Identify whether your debt falls under the written-contract or open-account category based on whether you signed a financial agreement.
• Determine when the clock started. Pull records of your last payment date or date of service. The clock usually starts from the date of last activity on the debt (last payment or date of delinquency), not the date of treatment (with a few state-specific exceptions like New York).
• Do NOT make any payment without understanding revival rules. If the debt is near or past the SOL in your state, a payment could restart the clock. This is especially critical in states that allow revival of expired claims.
• If a collector contacts you about old debt, demand written validation under the FDCPA. You have 30 days from their first contact to dispute in writing. This forces the collector to prove the debt is valid before they can continue collecting. See our guide to debt collector rights for a full walkthrough.
• If you are sued, respond before the deadline. File an answer raising the statute of limitations as an affirmative defense. Do not assume the court will catch it. See our guide on what to do when a hospital sues you.
• Keep records. Save every statement, collection letter, and payment receipt. If you need to prove when the clock started, documentation is your evidence.
• For help with any medical debt, including bills you cannot afford, see our medical debt relief guide.

This article provides general educational information about statutes of limitations for medical debt. It is not legal advice. Laws change, court interpretations vary, and your specific facts matter. The statute of limitations is a legal defense that must be raised properly and at the right time. If you are facing a lawsuit, collection action, or have questions about your specific debt, consult a qualified consumer law attorney in your state.
