The supplier can send the license to the NSC with a signed cover letter by the authorized or delegated official. The full 855s is not necessary. Now if they are adding a new state where they will be providing services, they will need to complete the appropriate sections of the 855S including the products/services in section 2 and section 4 requesting the state(s) they intend to serve.

CMN forms are only required on 5 items — Oxygen / Tens units (purchase) / Seat lift mechanisms/ Osteo genises Stims & Lymphadema pumps — What suppliers are calling CMNs are really just an order for the doctor to review and sign off on. It is important to realize that this should not be something that you just print off from your computer system. There needs to be something explaining from whom the order came/ their title / date and time. this means that a physicians office/snf/hospital discharge or someone called/faxed or electronically sent you a request for an item for a specific patient. Each jurisdictions has an exact description of a dispensing order and a detailed written order as well as WOPD (written order prior to deliver) {which is required on certain items)
