NASHVILLE, Tenn. — In a recent widespread probe review of
post-payment claims for CPAP devices, the Jurisdiction C DME MAC
(Cigna) said the review "showed that suppliers are not following

necessary and reasonable HCPCS code E0601 services." The calculated
error rate (determined by dividing the dollar amount of services
paid in error by the dollar amount of services medically reviewed)
was 63.94 percent. See "lessons learned" from the review on the
