We are publishing these final rules to amend our regulations to carry out section 221(m) of the Social Security Act (the Act). Section 221(m) affects our rules for when we will conduct a continuing disability review if you work and receive benefits under title II of the Act based on disability. (We interpret this section to include you if you receive both title II disability benefits and title XVI (Supplemental Security Income (SSI)) payments based on disability.) It also affects our rules on how we evaluate work activity when we decide if you have engaged in substantial gainful activity for purposes of determining whether your disability has ended. In addition, section 221(m) of the Act affects certain other standards we use when we determine whether your disability continues or ends. We are also amending our regulations concerning how we determine whether your disability continues or ends. These revisions will codify our existing operating instructions for how we consider certain work at the last two steps of our continuing disability review process. We are also revising our disability regulations to incorporate some rules which are contained in another part of our regulations and which apply if you are using a ticket under the Ticket to Work and Self-Sufficiency program (the Ticket to Work program). In addition, we are amending our regulations to eliminate the secondary substantial gainful activity amount that we currently use to evaluate work you did as an employee before January 2001.
