AMA Physician Masterfile

AMA Physician Masterfile

The American Medical Association (AMA) Physician Masterfile includes current and historical data on all physicians, including AMA members and nonmembers, and graduates of foreign medical schools who reside in the United States and who have met the educational and credentialing requirements necessary for recognition as physicians. A Masterfile record is created and ME number assigned when entering medical school or through the ECFMG. For medical students, there are two primary methods to create the initial record - the Student Outreach Program and the annual freshman matriculation file received from the Association of American Medical Colleges (AAMC).

The Physician Masterfile spans from undergraduate medical education through practice and comprise databases of

• 125 LCME-accredited medical schools
• 7,900 ACGME-accredited graduate medical education programs
• 1,600 teaching institutions; 820,000 physicians; and 19,000 medical group practices.

Physician records are never removed from the AMA Physician Masterfile, even in the case of a physician's death.
