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.
6-year SOL under § 37-1-3 applies when patient signed a written financial responsibility or admissions agreement (standard for most hospital admissions); if no written agreement exists, court may apply 4-year open-account SOL under N.M.S.A. § 37-1-4; minor and incapacitated-person tolling under N.M.S.A. § 37-1-10; NM official statutes are published by the NM Compilation Commission and accessible via nmonesource.com (linked from nmlegis.gov)

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 New Mexico 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 New Mexico?
You have 6 years from Date of last medical service rendered or date of first missed payment, under N.M.S.A. § 37-1-3.
Can I still sue after 6 years in New Mexico?
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?
New Mexico 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.
