Social Security's Office of Inspector General (OIG) did a recent study of delays in processing requests for reconsideration for disability claimants who are being threatened with benefit termination due to medical improvement. Generally, the claimants receive continuing benefits as their appeals continue through the hearing level so delays cost the agency money.
The thing about this is that almost all the causes of delay discussed in this report also apply to those applying for benefits and have the same underlying cause, lack of sufficient personnel to get the work done in a timely manner. The OIG report discusses these delays as if they have been caused by bungling, when for the most part, the fault lies Congress and the White House, which have failed to give the Social Security Administration adequate administrative funding.
I hope that OIG isn't implying that Social Security should prioritize cutting people off benefits over processing new claims for disability benefits but that does seem to be the attitude of Congressional Republicans.
