Here is some info I received from the American Board of Internal Medicine (ABIM), hope it helps others as it helped me!
Hello, I am a third year medical student at an Osteopathic Medical School (DO). I'm interested in pursuing Internal Medicine for residency and there are both DO and MD Residency Programs I'm looking into to continue my training. My questions are these: If I go through a DO (AOA) Internal Medicine Residency program, will I be eligible to take the Certification exam from the ABIM? If so, what are some of the advantages of being certified by the ABIM compared to the AOBIM (American Osteopathic Board of Internal Medicine)? Thank you for the info
ABIM Response:
Dear Dr. XXXXXXX (it's nice they addressed me as Dr.
and I'm not even a 4th year yet):
Thank you for your inquiry. If the osteopathic internship was completed in an institution that has an ACGME accredited internal medicine residency (that is, dually accredited AOA/ACGME program), it is possible that upon petition to the ABIM, month-for month credit can be granted for rotations that are supervised by the ACGME accredited program and identical to the rotations taken by the internal medicine residents in the ACGME accredited program. The Board would need to review the rotations and supporting documentation from the ACGME accredited internal medicine program at that institution to determine how much credit could be granted.
Otherwise, credit is not granted for osteopathic training toward fulfilling the requirements for admission to the Certification Examination in Internal Medicine, since only postgraduate training that has been accredited by the Accreditation Council for Graduate Medical Education or training completed in Canada and accredited either by the Royal College of Physicians and Surgeons of Canada or by the Professional Corporation of Physicians of Quebec, can be credited toward the Board's requirements.
I trust this is helpful.
