Some of the medical schools outside USA are of the British system and so the medical degree is MBBS/MBBCh, instead of MD as in the US system. (My degree is MBBS, too.) When FMGs have entered into the US health care system, they are addressed with "MD" suffix. While using MD suffix, the primary degree title is no longer used by most of the doctors. So how does the MD suffix implies? Does it represent the title "Medical Doctor" or replace the primary degree? Any point of view?
