Facilities should verify that they have separate numbers for each location. If you find that your facilities are using the same PTAN, you will need to submit the CMS 855S form to the NSC to get numbers for those locations. You must update the PTAN number on your ABC record by emailing us at accreditation@abcop.org.

DMEPOS Supplier Standards
42 CFR § 424.57 - Special payment rules for items furnished by DMEPOS suppliers and issuance of DMEPOS supplier billing privileges:

(b) General rule. A DMEPOS supplier must meet the following conditions in order to be eligible to receive payment for a Medicare-covered item:

(1) The supplier has submitted a completed application to CMS to furnish Medicare-covered items including required enrollment forms. (The supplier must enroll separate physical locations it uses to furnish Medicare-covered DMEPOS, with the exception of locations that it uses solely as warehouses or repair facilities.)

(2) The item was furnished on or after the date CMS issued to the supplier a DMEPOS supplier number conveying billing privileges. (CMS issues only one supplier number for each location.) This requirement does not apply to items furnished incident to a physician's service.
