When DDS cannot warrant revision of the prior unfavorable determination, but the claimant
has subsequently arranged to follow prescribed treatment, the onset date could be
that date when the claimant first arranged to follow prescribed treatment. For entitlement
to benefits, the case must meet the following requirements:
The impairment must meet the severity requirement;
The impairment must be expected to last 12 continuous months from the established
onset date; and
The claimant must meet insured status and other non-disability requirements.
