The American Medical Association publishes a set of codes that surgeons are required to use when billing for procedures called “current procedural terminology”. These codes gradually change to reflect changes and advances in surgical techniques. The system often does not provide a code for the latest procedures. When we bill an insurance carrier, they use these codes together with my fee to determine what they will pay on your behalf. The codes I bill most frequently appear below.
