When you base equivalency on a combination of impairments, cite the listed impairment
number most closely related to the most severe impairment. In these situations, 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 24505.015B. For a rationale example, see DI 28090.300B.
