How we determine fully insured status for a period of disability or disability insurance benefits.

In determining if you are fully insured for purposes of paragraph (b), (c), (d), or (e) of § 404.130 on disability insured status, we use the fully insured status requirements in § 404.110, but apply the following rules in determining when the period of elapsed years ends: (a) If you are a woman, or a man born after January 1, 1913, the period of elapsed years in § 404.110(b) used in determining the number of quarters of coverage (QCs) you need to be fully insured ends as of the earlier of— (1) The year you become age 62; or (2) The year in which— (i) Your period of disability begins; (ii) Your waiting period begins (see § 404.315(d)); or (iii) You become entitled to disability insurance benefits (if you do not have to serve a waiting period). (b) If you are a man born before January 2, 1913, the period of elapsed years in § 404.110(b) used in determining the number of QCs you need to be fully insured ends as of the earlier of— (1) The year 1975; or (2) The year specified in paragraph (a)(2) of this section.
