When the Clock Starts

In Wyoming, the limitations period for medical debt collection generally begins on Date cause of action accrues — typically date of breach (first missed payment) on the written agreement. Wyoming 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.

Wyo. Stat. § 1-3-105(a)(i) establishes a 10-year period for actions on 'any contract, agreement or promise in writing.' Medical bills supported by a signed patient financial-responsibility agreement are subject to this 10-year period. If no written agreement was signed — for example, emergency care rendered without paperwork — the 8-year period for oral and implied contracts under § 1-3-105(a)(ii) would apply instead.

What to Do Before the Deadline Runs

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