In accordance with the National Provider Number Final Rule, all
suppliers of durable medical equipment, prosthetics, orthotics, and
supplies (DMEPOS) are required to obtain a National Provider
Identifier (NPI) number for every business location. The only
exception to this requirement is when a DMEPOS supplier is a sole
proprietor (or considered an individual). Failure to comply with
this requirement will result in delayed processing or rejection of
both Medicare and direct bill Medicaid claims.
