[Code of Federal Regulations] [Title 20, Volume 2] [Revised as of April 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 20CFR404.250] [Page 86] TITLE 20--EMPLOYEES' BENEFITS CHAPTER III--SOCIAL SECURITY ADMINISTRATION PART 404_FEDERAL OLD-AGE, SURVIVORS AND DISABILITY INSURANCE (1950 ) --Table of Contents Subpart C_Computing Primary Insurance Amounts Sec. 404.250 Special computation rules for people who had a period of disability. If you were disabled at some time in your life, received disability insurance benefits, and those benefits were terminated because you recovered from your disability or because you engaged in substantial gainful activity, special rules apply in computing your primary insurance amount when you become eligible after 1978 for old-age insurance benefits or if you become re-entitled to disability insurance benefits or die. (For purposes of Sec. Sec. 404.250 through 404.252, we use the term second entitlement to refer to this situation.) There are two sets of rules: (a) Second entitlement within 12 months. If 12 months or fewer pass between the last month for which you received a disability insurance benefit and your second entitlement, see the rules in Sec. 404.251; and (b) Second entitlement after more than 12 months. If more than 12 months pass between the last month for which you received a disability insurance benefit and your second entitlement, see the rules in Sec. 404.252.
