Straight from the American Medical Association (AMA), this is the only CPT codebook with the official CPT coding rules and guidelines developed by the CPT Editorial Panel. Covers hundreds of code, guidelines and text changes. Key Features/Benefits: Improved, comprehensive index has been revised and enhanced for 2013 to aid in locating codes related to a specific procedure, service, anatomic site, condition, synonym, eponym, or abbreviation. An expansion of the pathology and laboratory index entries includes analytes and the elimination of redundancy throughout the rest of the index resulting in an index clearer and quicker to search. New listing of proprietary test names for multi-analyte assays puts you ahead of the curve by informing you of existing tests that have yet to meet all of the necessary requirements to be placed among the Category I codes. Summary of additions, deletions and revisions to provide a quick reference to 2013 changes without having to refer to previous editions.
