We are revising our regulations regarding when and how often we conduct continuing disability reviews (CDR), which are periodic reviews of eligibility required for benefit continuation.  Under our revised rules, we will add a category to the existing medical diary categories that we use to schedule CDRs and revise the criteria for assigning each of the medical diary categories to cases. The revised rules will also change the frequency with which we perform a CDR for claims with the medical diary category for permanent impairments. The revised changes will ensure that we continue to maintain appropriate stewardship of the disability program and identify medical improvement (MI) at its earliest point. The medical improvement standard is not changed.
