We are publishing final rules regarding the Reinstatement of Entitlement (Expedited Reinstatement) provision in section 112 of the Ticket to Work and Work Incentives Improvement Act of 1999. This provision allows former Social Security disability and Supplemental Security Income (SSI) disability or blindness beneficiaries, whose entitlement or eligibility had been terminated due to their work activity, to have their entitlement or eligibility reinstated in a timely fashion if they become unable to do substantial gainful work. These rules provide beneficiaries an additional incentive to return to work.
