Important information regarding the physician verification tool:

  • Most diplomates certified prior to 1990 are not required to participate in MOC but are strongly encouraged to do so.
  • All ABIM certifications issued in 1990 (1987 for critical care medicine and 1988 for geriatric medicine) and thereafter must be maintained through ABIM's MOC program.
  • ABIM's website serves as primary source verification.
  • Diplomates are publicly reported as participating in MOC for all certifications as long as they are participating in MOC for one certification area.
  • Physicians are publicly reported as inactive if they were once certified by ABIM but now, for non-disciplinary reasons, they no longer have an active medical license in any jurisdiction.
  • In other cases of a physician being reported as not certified, the following descriptors are included to provide greater transparency for patients who rely on this information:
    • Lapsed will indicate non-disciplinary loss of certification, including not meeting MOC requirements, or voluntary deactivation of certification. Certification may be restored by meeting MOC requirements for the applicable certificate.
    • Suspended will indicate a loss of certification due to disciplinary action where there is a defined pathway to restoration of certification.
    • Revoked will indicate loss of certification due to disciplinary action for which ABIM has determined that the conduct underlying the sanction does not warrant a defined pathway for restoration of certification at the time of disciplinary sanction.
  • Diplomates are not required to maintain underlying certifications to stay certified in subspecialty areas.
  • Certification status is updated to this system within 5 days of notification to the physicians. Data elements, such as name changes, are updated in ABIM's records within 24 hours of being processed by ABIM.
  • Diplomates who have earned certification through a Qualifying Board may not be required to meet ABIM’s underlying certification requirement.
  • If you do not find your physician or they are listed as not certified, they may be certified by another board of the American Board of Medical Specialties.
