When the MC/PC or adjudicatorbases equivalency on a combination of impairments, the
MC/PC or adjudicator will cite the listed impairment number most closely related to
the most severe impairment. In these situations, the MC or PC will provide a medical
explanation to show how the interaction of the combined impairments equates with the
intended severity of a listed impairment(s).
For more information on medical equivalence, see DI 24508.010. For a rationale example, see DI 28090.300B.
