Section 221(c) of the Act requires SSA to review at least 50 percent of favorable
Title II and concurrent Title II and Title XVI initial and reconsideration determinations
that adjudicating components make on a preeffectuation basis. To the extent feasible,
the sample selection is comprised of those determinations most likely to be incorrect.
Favorable Title XVIII Medicare for Qualified Government Employment disability claims
and deemed disabled widow(er) Medicare claims are also included in the preefectuation
review (PER) sample of adjudicating component favorable determinations.
The PER review detects and corrects erroneous favorable Title II determinations before
the determination is effectuated.
