The Ruling that Michael Astrue signed on February 12 wasn't the only one he signed that day. Tomorrow's Federal Register will have another Ruling he signed that day, although this one isn't that important. Social Security Ruling 13-3p says that:
In this SSR [Social Security Ruling], we are adopting as our nationwide policy the holding in Difford v. Secretary of Health and Human Services, 910 F.2d 1316 (6th Cir. 1990). We have applied the holding in that decision under Acquiescence Ruling (AR) 92-2(6) to cases involving beneficiaries residing in States within the Sixth Circuit ... Because this SSR addresses the issue decided by the Difford court, in this issue of the Federal Register, we are also publishing a notice rescinding AR 92-2(6) as obsolete ...
In Difford, the United States Court of Appeals for the Sixth Circuit interpreted the references to “now” and “current” in section 223(f) of the Act to require that when we review a medical disability cessation determination or decision, we must consider whether the beneficiary was disabled at any time through the date of the adjudicator(s)’s final determination or decision.
