On May 20, 2009, CMS issued an updated educational article on DMEPOS supplier accreditation requirements to provide information for suppliers who choose not to become accredited. CMS notes that a DMEPOS supplier’s Medicare Part B billing privileges will be revoked on or after October 1, 2009 if the supplier fails to obtain accreditation or a voluntary termination has not been received by the National Supplier Clearinghouse by September 30, 2009. If a supplier chooses not to become accredited, they must submit an amended CMS 855S to prevent revocation and subsequent exclusion from the Medicare program. For pharmacies that choose not to become accredited but wish to remain a DMEPOS supplier to continue to bill Medicare for drugs and biologicals only, an amended CMS 855S must be completed, reflecting which drugs and biologicals the pharmacy will provide to beneficiaries.
