American Board of Physician Specialties

The American Board of Physician Specialties (ABPS), the official certifying body for the American Association of Physician Specialists (AAPS) is a non-profit umbrella organization for sixteen medical specialty boards that certifies and re-certifies physicians in fourteen medical specialties in the United States and Canada. The ABPS is one of three organizations overseeing Doctor of Medicine (M.D.) and Doctor of Osteopathic Medicine (D.O.) certification in the United States. The ABPS assists its Member Boards in developing and implementing educational and professional standards to evaluate and certify physician specialists. It is recognized by the U.S. Department of Labor as well as the Centers for Medicare and Medicaid Services (CMS).
History.
The American Association of Physician Specialists (AAPS) is the smallest of three multi-specialty physician/surgeon certifying entities in the United States, providing board certification to both M.D. and D.O. physicians. The AAPS has grouped its certification activities within a single subdivision called the American Board of Physician Specialties (ABPS). In August 2005, the ABPS name was registered to AAPS. The ABPS implements certification functions under the direction of AAPS.
AAPS (originally known as the American Association of Osteopathic Physicians was founded in 1952 by Dr. E.O. Martin. Since 1984, AAPS has provided a headquarters for medical specialty boards of certification.
Recognition by state medical boards.
Today in the U.S. and its territories, there are seventy (70) state medical boards—some state medical boards are composed of an M.D. board and a D.O. board while others are combined as one, called a "composite board". Of the 70 state boards, the vast majority "do not" differentiate between any of the three nationally recognized multi-specialty boards of certification (ABMS, ABPS, AOABOS). In other words, the majority of the state medical boards are silent (or neutral) as to which board a given physician is certified by.
The remaining boards, approximately twenty (20), have established specific rules for physician advertising by which boards have to petition and receive permission for physicians to be able to advertise themselves as "board certified".
Those twenty (20) boards are:
Physicians certified by ABPS and licensed by the Medical Board of California are prohibited from using the term "board certified" unless they are also certified by an American Board of Medical Specialties board.
It also appears that certification by an ABPS member board is not sufficient to allow use of the term "board certified" by physicians licensed in the State of New York. However, interpreting the law in New York is more complex.
