Provider types
Physician (MD/DO) Credentialing Services
Physicians (doctors of medicine or osteopathy) enroll in Medicare individually on the CMS-855I. For Texas Medicaid, most physicians must be enrolled in Medicare first, and the Texas Medical Board issues the license payers verify.

Medicare
Physicians enroll on the CMS-855I, the individual Medicare enrollment application, and reassign benefits to the group that bills.
Texas Medicaid
All physicians except gynecologists, pediatricians, pediatric subspecialists, pediatric psychiatrists, and providers performing only THSteps medical or dental checkups must be enrolled in Medicare before enrolling in Texas Medicaid.
Enrollment in Texas Medicaid comes before any Medicaid managed care plan can enroll you; each plan then contracts and credentials separately.
Licensure
Texas physician licenses are issued by the Texas Medical Board (TMB).
Specialty pages
Specialty-specific notes live under medical specialties, including radiology, which is a physician specialty rather than a separate provider type.
