When the Clock Starts
In Missouri, the limitations period for medical debt collection generally begins on Date of last service rendered or date of first missed payment; cause of action accrues at time of breach or failure to pay. Missouri does not apply a general discovery rule to this claim type — the date of the event controls, which makes early action critical.

Exceptions That Can Extend the Deadline
- Minors: the clock is generally paused while the injured person is under 18.
- Fraudulent concealment: if the defendant actively hid the wrongdoing, the deadline may be extended until it was or should have been uncovered.
- Defendant leaves the state: absence can pause the clock in many circumstances.
- Government-claim trap: Missouri Tort Claims Act notice procedures apply for claims against public hospital districts; contract claims against public entities are generally governed by the same 5-year SOL without additional pre-suit notice requirement for purely contractual medical debt.
RSMo § 516.120 applies to all contract actions — written, oral, and implied — with a uniform 5-year SOL. Open accounts for medical services are also covered under RSMo § 516.130 (also 5 years). Missouri does not distinguish written vs. oral medical debt for SOL purposes; both are 5 years. Minor tolling under RSMo § 516.170 extends the period until 21 or 1 year after reaching majority.

What to Do Before the Deadline Runs
- Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
- Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
- Send preservation/notice letters where required (especially for Missouri government defendants).
- If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

Frequently Asked Questions
How long do I have to sue over unpaid medical bills in Missouri?
You have 5 years from Date of last service rendered or date of first missed payment; cause of action accrues at time of breach or failure to pay, under RSMo § 516.120.
Can I still sue after 5 years in Missouri?
Usually no — courts dismiss claims filed after the statute of limitations expires. Narrow exceptions (tolling for minors, fraudulent concealment) can extend the deadline; whether one applies depends on your facts.
What if the victim was a minor?
Missouri generally pauses ("tolls") the deadline while the injured person is under 18, giving them time to file after reaching adulthood. Special limits can still apply, so check the statute.
Is the deadline different for claims against the government?
Missouri Tort Claims Act notice procedures apply for claims against public hospital districts; contract claims against public entities are generally governed by the same 5-year SOL without additional pre-suit notice requirement for purely contractual medical debt.
