American Board of Internal Medicine

The American Board of Internal Medicine (ABIM) is a non‑profit organization that provides board certification for physicians specializing in internal medicine and its subspecialties. It develops and administers the initial certification examinations that assess a physician’s knowledge and clinical judgment. In addition to initial certification, ABIM offers a Maintenance of Certification (MOC) program that requires ongoing learning, assessment, and practice improvement activities. The organization also produces educational resources and standards that guide internal medicine training and practice across the United States.

ABIM operates as an independent, physician‑led entity whose headquarters are located in the United States of America. It works closely with residency and fellowship programs, hospitals, and health systems to ensure that certified physicians meet nationally recognized standards. As one of the member boards of the American Board of Medical Specialties, ABIM’s certification is widely accepted by employers, insurers, and regulatory bodies throughout the country.

ABIM’s distinguishing attributes include its responsibility for upholding the integrity and standards of internal medicine, its governance model that integrates physician expertise with public interest oversight, and its commitment to transparent communication with stakeholders. In May 2023, the organization disclosed that a zero‑day vulnerability in the MOVEit Transfer service led to unauthorized access to personal information, including names and Social Security numbers, for over 13,000 individuals. ABIM responded by containing the breach, notifying affected parties, and offering credit monitoring services. This incident underscores the need for robust cybersecurity protections even for organizations whose primary mission is medical certification.
