Physician Assistants Enrolling in Medicare

Beginning October 6, 2025, Physician Assistants are required to submit the CMS-855I enrollment application along with a reassignment of benefits. This update is designed to help reduce delays in the enrollment process and ensure timely approval. Both the provider and the Authorized or Delegated Official must complete and sign the certification statement included in the application.

To comply, Physician Assistants can use the paper CMS-855I form, which is available at Noridian JE Forms Enrollment CMS-855I. When completing the paper form, be sure to fill out sections 1, 2, 3, 4F, and 15, and include all relevant supporting documentation.

Alternatively, the reassignment of benefits can be added through the Provider Enrollment, Chain and Ownership System (PECOS) by submitting an initial application, a change of information, or another applicable scenario. Once the application is complete, it must be certified electronically and submitted for processing. Following this process will help ensure a smoother and more efficient enrollment experience.
