If the CPD was a medical-vocational decision, the rationale must include an explanation
of the functional limitations (e.g., the ability to lift and carry, sit, stand, and
walk) based on the medical findings and a statement of residual functional capacity
(RFC). Compare this explanation with an assessment of the “MIRS RFC” (current functional
capacity considering only the impairments that were present at the CPD). For more
information on the “MIRS RFC”, see DI 28015.300.
