Internal medicine

Internal Medicine (IM) is a very broad specialty that encompasses many subspecialties. These include, but are not limited to, Cardiovascular (Cards), Endocrinology/Diabetes/Metabolism (Endo), Gastroenterology (GI), Hematology/Oncology (Heme/Onc), Infectious Disease (ID), Nephrology (Nephro), Pulmonology (Pulm), and Rheumatology (Rheum) in adult and geriatric populations. Internal medicine does not typically treat pediatric or pregnant patients.

In the United States, credentialing and certification of these subspecialties is handled by the American Board of Internal Medicine (ABIM).

The Certification Exams typically take place in mid- to late-August, and require physicians to register between December 1st - April 15th.
