I am needing help in finding any coding information/guidelines for plastic's ex.. books, coding seminars, web sites etc... I had a physican preform a "small breast reduction" and said that since he only removed 100g of tissue that it is not considered a breast reduction? They also did a mastopexy and according to the medicare cci edits a breast reduction (19318) is mutually exclusive of a mastopexy (19316). I am fairly new at coding these and would like to find more information and guidance for coding these types of procedures. Any help would be greatly appreciated!
