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.
