CMS has issued a transmittal to contractors and an educational article providing further guidance to suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) regarding accreditation requirements. Effective for claims with dates of service on or after July 5, 2011, CMS is implementing accreditation edits that will automatically deny claims for certain DMEPOS codes unless: (1) the DMEPOS supplier has been identified as accredited for the timeframe that covers the date of service on the claim; or (2) the DMEPOS supplier is currently exempt from meeting the accreditation requirements.
