CMS has announced that all existing durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) suppliers will need to submit proof of accreditation by a deemed accreditation organization by September 30, 2009. This requirement also will apply to physicians and other providers who submit Part B claims for DMEPOS. CMS intends to announce a separate accreditation deadline for new DMEPOS suppliers in the near future.
