The Current Procedural Terminology (CPT®) code set, created and maintained by the American Medical Association (AMA), is the language of medicine today and the code to its future. This system of terminology is the most widely accepted medical nomenclature used to report medical procedures and services under public and private health insurance programs. CPT coding is also used for administrative management purposes such as claims processing and developing guidelines for medical care review. Each year, via a rigorous, evidence-based, and transparent process, the independent CPT Editorial Panel revises, creates, or deletes hundreds of codes in order to reflect current medical practice. CPT is copyrighted by the AMA and as such must be licensed to be used in electronic products or other forms.
