Every year I handle at least one claim involving adult listing 12.05C. That listing requires:
A valid verbal, performance, or full scale IQ of 60 through 70 and a physical or other mental impairment imposing an additional and significant work-related limitation of function;
The listing is a two-pronged test. The first prong is a valid IQ score from 60 to 70. The second is some other mental impairment, or a physical impairment, that imposes a significant work-related limitation of function.
There are a few things to bear in mind about this listing:
- The mental impairment must have "manifested during the developmental period; i.e., the evidence demonstrates or supports onset of the impairment before age 22." Ideally, there is an IQ test somewhere in the school records. Someone who meets this listing in all likelihood would have been a special education student. So get the school records.
- The lowest number of the Weschler series is used. See 12.00D.6.c.
- A test score slightly above 70 might be okay (but I wouldn't count on it). See POMS DI 24515.056 section D.1.c.
- The additional impairment must result in a "significant work-related limitation of function." While that phrase is not defined, it roughly equates to "severe" at step 2 of the sequential evaluation. I had a recent Maine disability claim where a lifting restriction of 25 pounds satisfied this prong of the test.
- To establish the additional impairment, try to obtain a treating doctor's medical source statement assessing work-related functional limitations.
The criteria for this listed impairment are pretty clear. If you have a qualifying IQ test, and evidence of a significant work-related limitation, there is little reason for a hearing. The claim can be granted on the record.
