Home Provider Part B Medicare Areas Provider Enrollment

All physicians, practitioners, and other suppliers who provide services to Medicare beneficiaries must enroll in the Medicare program before claims can be submitted. At the time of enrollment, Medicare assigns a two-digit specialty code that corresponds to the specialty type declared by the applicant on the enrollment form. The specialties listed below are the only specialties currently recognized by the Centers for Medicare & Medicaid Services (CMS) for purposes of enrollment in the Medicare program by Part B Medicare carriers.

Primary/Secondary Specialty Codes
Physicians may designate only one primary specialty but may designate multiple secondary specialties on the CMS 855I enrollment form. Non-physician practitioners who want to enroll as more than one non-physician specialty type must submit a separate CMS-855I enrollment form for each specialty.

Changes in Specialty Codes
Physicians should monitor their specialty status to ensure that they are enrolled in the specialty type that most accurately represents their practice. This is particularly important as physicians change the focus of their practice and become more specialized. Failure to notify Medicare of specialty changes can affect reimbursement. Use form CMS-855I to report specialty changes.
