Q: How do I know which provider enrollment application to use?
A: You may either use the
Provider Enrollment, Chain, and Ownership System (PECOS) 
to enroll online or mail a paper application form. PECOS supports the Medicare provider and supplier enrollment process by capturing provider/supplier information from the CMS-855 family of forms. The system manages, tracks, and validates enrollment data collected in both paper form and electronically via the internet. To find out more about PECOS, please refer to the
PECOS FAQs .
The direct link for each Medicare provider/supplier enrollment application is shown below:
• Clinics/group practices and certain other suppliers: CMS-855B 
• Physicians and non-physician practitioners (including clinical psychologists): CMS-855I • Ordering, certifying and prescribing providers: CMS-855O Note: Ordering/referring providers must meet the criteria specified by
SE 1305 • Durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) suppliers: CMS-855S Note: CGS Medicare is the DMEPOS Medicare Administrative Contractor (MAC) for Florida, Puerto Rico, and the U.S. Virgin Islands.
Note: The Centers for Medicare & Medicaid Services approved two new enrollment forms, CMS-855C and CMS-855POH. For more information, access the
change request (CR) 9120 and the
CMS Forms List page.
