(a) In some cases, the Board may determine that a claimant is not currently disabled but was previously disabled for a specified period of time in the past. This can occur when—
(1) The disability application was filed before the claimant's disability ended but the Board did not make the initial determination of disability until after the claimant's disability ended; or
(2) The disability application was filed after the claimant's disability ended but no later than the 12th month after the month the disability ended.
(b) When evaluating a claim for a previous disability, the Board follows the steps in §220.100 to determine whether a disability existed, and follows the steps in §220.180 to determine when the disability ended.
The claimant, although fully recovered medically and regularly employed, filed an application on December 3, 1984 for a determination of disability for the period June 16, 1982 through January 31, 1984. The Board reviewed his claim in January 1985 and determined that he was disabled for the prior period which began June 16, 1982 and continued through January 31, 1984. A disability annuity is payable to the employee only for the period December 1, 1983 through January 31, 1984.
An annuity may not begin any earlier than the 1st of the 12th month before the month in which the application was filed (See part 218 of this chapter for the rules on when an annuity may begin).
