The American Medical Association (AMA) defines Usual, Customary and Reasonable (UCR) as:
"Usual": the fee an individual physician usually charges his or her private patient for a given service (i.e., his or her own usual fee);
"Customary": a fee that is within the range of usual fees physicians of similar training and experience currently charge for the same service within the same specific and limited geographical area; and
"Reasonable": a fee that meets the above two criteria and is justifiable, considering the special circumstances of the particular case in question without regard to payments that governmental or private plans have discounted.
