To make this more complicated, different state medical boards have different rules on what boards are "recognized" and how you are allowed to advertise various board certifications.
Texas,for example,only recognizes ABMS member boards and a couple of other boards. You can only advertise as board certified if you are a member of these boards. Furthermore you can't advertise yourself as being board certified in a specialty that is not ABMS covered.
New York,on the other hand lets you advertise more liberally even though they only "recognize" ABMS and Canadian boards. The rule is that you have to state the name of the board that certifies you. You will see statements like these in New York physician ads:
Board Certified by the American Board of Anti-Aging
Board Certified by the American Board of Laser Surgery
Hey, spending a weekend in Las Vegas is a great way to get board certified!
