Medical debt laws in South Dakota
In South Dakota, the statute of limitations on medical debt is 6 years (S.D. Codified Laws § 15-2-13). Medical bills fall under SDCL 15-2-13(1)'s single 6-year period for any 'contract, obligation, or liability, express or implied,' which South Dakota courts apply to open accounts as well, so the written/oral/open-account distinction does not change the answer (the UCC 4-year period in SDCL 57A-2-725 applies only to sales of goods, not medical services). 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.
| Written contracts | 6 years |

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: Yes — a payment of principal or interest restarts the 6-year period, and a written, signed acknowledgment or new promise also restarts it; an oral acknowledgment does not (SDCL 15-2-29, which requires a signed writing for acknowledgments but expressly 'shall not alter the effect of any payment of principal or interest').
Protections that apply in South Dakota
- 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 South Dakota sets for collectors
South Dakota relies primarily on the federal Fair Debt Collection Practices Act (FDCPA), which applies in every state and covers third-party collectors and debt buyers.
No — South Dakota does not require collection agencies or debt collectors to be licensed, registered, or bonded (it is one of the roughly dozen states with no collection-agency license).
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 South Dakota.

- 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.

Common questions
How long can a debt collector pursue medical debt in South Dakota?
The statute of limitations on medical debt in South Dakota is 6 years (S.D. Codified Laws § 15-2-13). Medical bills fall under SDCL 15-2-13(1)'s single 6-year period for any 'contract, obligation, or liability, express or implied,' which South Dakota courts apply to open accounts as well, so the written/oral/open-account distinction does not change the answer (the UCC 4-year period in SDCL 57A-2-725 applies only to sales of goods, not medical services). 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 South Dakota?
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 South Dakota?
Yes — a payment of principal or interest restarts the 6-year period, and a written, signed acknowledgment or new promise also restarts it; an oral acknowledgment does not (SDCL 15-2-29, which requires a signed writing for acknowledgments but expressly 'shall not alter the effect of any payment of principal or interest').
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 South Dakota 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.
