Provider enrollment application types

Q: How do I know which provider enrollment application to use?
A: You may either use the PECOS external link 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 external link.
The direct link for each Medicare provider/supplier enrollment application is shown below:
Institutional providers: CMS-855A external pdf file
Clinics/group practices and certain other suppliers: CMS-855B external pdf file
Physicians and non-physician practitioners (including clinical psychologists): CMS-855I external pdf file
