The MC or PC completes an SSA-392-SUP when:
An SSA-4734-F4-SUP is in file, and
A mental impairment of less than listing level severity requiring an RFC assessment is present.
For a further explanation of when to use the SSA-392-SUP, see GN 04440.135.
When an MRFC is not in the file, but one is required, the reviewing MC or PC will prepare the assessment on an SSA-4734-F4-SUP. The reviewing MC or PC should not use the SSA-392-SUP to prepare an MRFC assessment.
