SSI continuing disability reviews (CDRs) are periodic reviews conducted to ensure recipients are still disabled according to agency rules. The frequency of these reviews is dependent on the likelihood that a recipient’s medical condition will change. Non-disability redeterminations (redeterminations) are periodic reviews that verify living arrangements, income levels, and other non-disability factors related to SSI eligibility. Similar to CDRs, the frequency of redeterminations is determined by the probability that changes affecting eligibility will occur. CDRs and redeterminations are key activities in ensuring the integrity of the SSI program and maintaining and improving payment accuracy. .
