The Social Security Administration (SSA) reported in January 2014 that it is behind schedule in assessing the continued eligibility of recipients in its two disability programs, Disability Insurance (DI) and Supplemental Security Income (SSI),and has accumulated a backlog of 1.3 million continuing disability reviews (CDRs). From fiscal years 2000 to 2011, the numbers of adult and child CDRs conducted fell about 70 percent. Children make up about one fifth of all SSI recipients, and GAO reported in 2012 that many of their CDRs were overdue. For example, more than 24,000 CDRs for children with mental impairments were overdue by 6 or more years, including over 6,000 CDRs for children who were expected to medically improve within 6 to 18 months of their initial determination. GAO also identified several cases which exceeded their scheduled review date by 13 years or more. When CDRs are not conducted as scheduled, the potential for improper payments increases as some recipients receive benefits for which they are no longer eligible. In September 2011, SSA’s Office of the Inspector General estimated that SSA had paid about $1.4 billion in SSI benefits to children who should have not received them. SSA attributes delays in performing CDRs to resource limitations and other factors; SSA also generally gives lower priority to conducting CDRs for children receiving SSI. In 2012, GAO recommended that SSA eliminate the existing CDR backlog for children with impairments who are likely to improve, and regularly conduct reviews for this group. While SSA generally agreed with GAO’s recommendation, the CDR backlog remains.
