Effective October 1, 2000, most SSDI beneficiaries with disabilities, if enrolled
                  in Medicare, can receive at least 93 consecutive months of hospital coverage (Part
                  A) and medical insurance (Part B) if enrolled, and prescription drug coverage (Part
                  D), if enrolled, after the TWP. This is true even if the beneficiary is working at
                  the SGA level.
               
               Prior to October 1, 2000, Medicare coverage continued for at least 39 months after
                  the TWP. After the extended period of Medicare coverage, an individual can buy Medicare
                  coverage by paying a monthly premium.
