Statute of Limitations

4 yearsMinn. Stat. § 541.076

Medical malpractice claims must be filed within 4 years of the date of the negligent act or omission, regardless of when the injury was discovered.

Exceptions

Foreign ObjectsMinn. Stat. § 541.076

Minnesota medical-malpractice timing is controlled by Section 541.076. Foreign-object and discovery-rule questions should be reviewed by an attorney because the statutory text does not provide a simple public self-help rule.

Minors — Extended until age 8 or within 4 years of the act, whichever is longerMinn. Stat. § 541.15

For children under 8, the statute is tolled. The claim must be filed by the child's 8th birthday or within 4 years of the act, whichever provides a longer period.
