When we review a determination that disability has medically ceased, we consider the
            recipient's disability through the date of the current determination. We determine
            whether the recipient was or has again become disabled at any point through the current
            date. Social

         Pursuant to Public Law (P.L.) 104-193, all Title XVI childhood disability recipients
            who attained age 18 on or after August 22, 1996 and were eligible as children in the
            month before the month in which they attained age 18, must have their eligibility
            redetermined under the adult standards for initial claims. We must notify the recipient
            in writing prior to completing the disability redetermination. 20 CFR
