From the conclusions of Comparing the Social Security Administration’s Disability Determination Services’ Workload Statistics During the COVID-19 Pandemic to Prior Years, a report by Social Security's Office of Inspector General:
Although the DDSs [Disability Determination Services] experienced some increases/decreases in their workload categories from year to year for the period April 2016 through March 2021, the largest year-to-year changes occurred from the COVID-19 period of April 2020 to March 2021 compared to the prior-year period (April 2019 to March 2020). DDSs received 15.9 percent fewer initial claims during the COVID-19 period compared to the prior-year period. Additionally, SSA sent 40.2 percent fewer CDRs [Continuing Disability Reviews] to the DDS during the COVID-19 period compared to the prior-year period.
Despite the decrease in initial claims, DDS processing times increased during the COVID-19 period, which indicates claimants waited longer for DDSs to make medical determinations. Furthermore, even though receipts decreased for initial claims, reconsiderations, and CDRs, the pending workloads for these groups increased—which indicates the DDSs could not keep pace with workloads received.
Finally, we noted that DDSs significantly decreased the use of consultative examinations; however, allowance/continuance rates remained relatively the same when comparing the COVID-19 period to the prior-year period. ...
