If we establish that the claimant is not performing substantial gainful activity (SGA)
at step one of the sequential evaluation process, next we must determine whether they
have a medically determinable physical or mental impairment.
Once we establish the existence of an MDI, we will determine whether that MDI is medically
severe and meets the duration requirement.
If the evidence is insufficient to establish the existence of a medically severe MDI
(or multiple concurrent impairments that, when considered in combination, are severe)
the sequential evaluation process ends at step two, and we will find that the claimant
is not disabled.
For information on the sequential evaluation process, see DI 22001.001.
For information on establishing a severe MDI in a Title XVI disabled child claim,
