Brought to you by the American Medical Association (AMA), the developer of CPT codes, this is the only codebook  with official CPT coding rules and guidelines developed by the CPT Editorial Panel. In addition to covering hundreds of code, guideline, and text changes, the 2011 edition contains extensive changes to the Surgery section, including important updates to subsections such as Excision and Debridement.
