The MC and PC:
Sign assessments and determinations; and
Indicate that his or her signature completes the medical portion of the disability determination.
An MC who is a physician takes responsibility for the medical portion of the determination, except in cases where a PC may perform this function.
A PC may perform this function when:
a mental impairment is the only impairment in the claim; or
there is a combination of a mental impairment with a physical impairment, but the mental impairment alone justifies a finding of disability.
The MC or PC who is taking responsibility for the medical portion of the determination signs the disability determination forms and all supporting documents relevant to the determination that require a signature.
In cases where there is evidence of mental and physical impairment(s), and a PC reviews the case, the PC evaluates only the mental impairment(s) and the MC evaluates the physical impairment(s).
In cases where the combination of physical and mental impairments may be equivalent to a medical listing, the MC and PC confer, both complete and sign an SSA-416 (Medical Evaluation), and one of the consultants takes overall responsibility to sign the rationale supporting the equivalence. For additional information on the SSA-416, see DI 24501.006.
