Medical debt laws in Wisconsin
In Wisconsin, the statute of limitations on medical debt is 6 years (Wis. Stat. § 893.43(1); Wis. Stat. § 893.05 (expiration extinguishes the right as well as the remedy)). Wisconsin applies one 6-year period to all contract debts: Wis. Stat. § 893.43(1) covers 'any contract, obligation, or liability, express or implied, including an action to recover fees for professional services,' which expressly reaches medical/professional bills, written or not. Uniquely, when the 6 years expire the debt itself is extinguished, not just the remedy (Wis. Stat. § 893.05). That clock decides whether a collector can win a lawsuit against you — which changes what you should do next, so check the dates on the bill before you do anything else.

What the time limit actually means
The statute of limitations does not erase a debt — it limits how long a collector can successfully sue over it. A time-barred debt can still be requested, reported (within credit-reporting time limits), and settled. But if a collector sues after the period has run and you raise the statute of limitations as a defense, the case should be dismissed. The defense is not automatic: you must respond to the lawsuit to use it.
Careful: Before expiry, a partial payment restarts the 6-year clock under Wisconsin case law (whose effect is preserved by Wis. Stat. § 893.48) and a new promise or acknowledgment must be in a signed writing (Wis. Stat. § 893.45) — but once the period has run the debt is extinguished under § 893.05 and no payment or promise can revive it.
Protections that apply in Wisconsin
- Charity care is federal law. Nonprofit hospitals must maintain a written Financial Assistance Policy and publicize it (IRS §501(r)). If your bill is from a nonprofit hospital, ask for the FAP application before paying anything. How to apply →
- Surprise out-of-network bills. The federal No Surprises Act bans most out-of-network balance billing for emergency care and for out-of-network providers at in-network facilities. When a bill is illegal →
- Credit reporting. The national bureaus no longer report paid medical collections, medical collections under $500, or those less than a year old.
Rules Wisconsin sets for collectors
Beyond the federal FDCPA, Wisconsin has its own collection statute — the Wisconsin Consumer Act — debt collection chapter (Wis. Stat. ch. 427 (prohibited practices at § 427.104)). Chapter 427 of the Wisconsin Consumer Act prohibits harassment, threats, misrepresentation, and other abusive collection practices in consumer credit transactions, applies to original creditors as well as third-party collectors, and gives consumers damages remedies under ch. 425.
Yes — collection agencies must be licensed by the Wisconsin Department of Financial Institutions and bonded under Wis. Stat. § 218.04.
Under the FDCPA, within five days of first contacting you a collector must send a written validation notice (15 U.S.C. §1692g). If you dispute the debt in writing within 30 days of that notice, the collector must stop collection activity until it mails you verification. There is no legal deadline for the collector to respond — but until it does, it cannot lawfully keep collecting.
If a collector is calling: the first 24 hours
- Do not confirm the debt is yours on the phone, and do not make a payment yet — get everything in writing first.
- Ask for the collector’s company name, mailing address, and the amount claimed. Write down the date and time.
- Check the dates: if the last activity on the bill is older than 6 years, the debt may be time-barred in Wisconsin.

- If the bill is from a hospital, request an itemized bill and ask about financial assistance — billing errors are common and assistance is often retroactive.
Where to complain in Wisconsin
Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), Bureau of Consumer Protection (Wisconsin's primary consumer-complaint agency, working with the Wisconsin DOJ) handles collection complaints at the state level. Federally, file with the Consumer Financial Protection Bureau — complaints become part of the public record collectors are judged on.
Common questions
How long can a debt collector pursue medical debt in Wisconsin?
The statute of limitations on medical debt in Wisconsin is 6 years (Wis. Stat. § 893.43(1); Wis. Stat. § 893.05 (expiration extinguishes the right as well as the remedy)). Wisconsin applies one 6-year period to all contract debts: Wis. Stat. § 893.43(1) covers 'any contract, obligation, or liability, express or implied, including an action to recover fees for professional services,' which expressly reaches medical/professional bills, written or not. Uniquely, when the 6 years expire the debt itself is extinguished, not just the remedy (Wis. Stat. § 893.05). After that period, a lawsuit to collect can be challenged as time-barred, though collectors may still ask you to pay voluntarily.
Can I be sued for a medical bill after 6 years in Wisconsin?
A collector can still file a lawsuit after the limitations period, but the statute of limitations is a defense: if you raise it, a time-barred case should be dismissed. It is not automatic — you must respond to the lawsuit and assert it. Never ignore a court summons.
Does making a small payment restart the clock in Wisconsin?
Before expiry, a partial payment restarts the 6-year clock under Wisconsin case law (whose effect is preserved by Wis. Stat. § 893.48) and a new promise or acknowledgment must be in a signed writing (Wis. Stat. § 893.45) — but once the period has run the debt is extinguished under § 893.05 and no payment or promise can revive it.
Does unpaid medical debt go on my credit report?
Since 2023, the three national credit bureaus (Equifax, Experian, TransUnion) do not report paid medical collections, medical collections under $500, or medical collections less than a year old. Larger, older unpaid medical collections can still appear.
Do hospitals in Wisconsin have to offer financial assistance?
Every nonprofit hospital in the United States is required by federal law (IRS Section 501(r)) to have a written Financial Assistance Policy and to tell patients about it. Ask the billing office for the Financial Assistance Policy application, in writing.
How do I dispute a medical bill that went to collections?
Send the collector a written debt validation request. Under the federal FDCPA (15 U.S.C. §1692g), if you dispute the debt in writing within 30 days of their first notice, the collector must stop collecting until it mails you verification of the debt.
