32 CFR 757.17: Statute of limitations.

(a) Federal. Claims asserted under the MCRA or against an automobile liability insurer through 10 U.S.C. 1095 are founded in tort and must be brought within 3 years after the action “first accrues” (28 U.S.C. 2415b). Normally, a medical care claim “first accrues” on the initial date of treatment.

(b) Claims asserted under 10 U.S.C. 1095. Although legal arguments can be made that claims asserted under 10 U.S.C. 1095 against a no-fault or personal injury protection insurer are founded in contract and can be brought within 6 years (28 U.S.C. 2415a), all claims should be asserted within 3 years of the date when the claim accrued. However, some states require notice of such claims to be filed within a shorter period of time.
