When Do You Get a Medicare Provider Number?
Doctors and other health care professionals receive a Medicare provider number after approval of the online application referred to as the Provider Enrollment, Chain and Ownership System, known as PECOS, or the paper enrollment process, CMS-855, says Centers for Medicare & Medicaid Services. PECOS provides additional benefits after approval.
PECOS allows providers to review the status of their application and all information provided with the application. Once approved, providers use the system to review their information on file and make changes to their Medicare enrollments, according to Centers for Medicare & Medicaid Services. Providers contact the Medicare Administrative Contractor, or MAC, with any questions concerning the application.
