CPT Medical Billing Codes online

However the AMA does allow a personal, non-commercial search of the Current Procedural Terminology Fourth Edition (“CPT”) manual here on the AMA website. You have to accept their terms and conditions before using the search function.

Unfortunately, this search tool limits the number of codes you can look up and provides limited information. However it does give you a good description, general information, and the Medicare facility and non-facility payment for the geographic area selected. To obtain more detailed information requires a subscription and payment of the AMA license fee.

The AMA also offers all the latest CPT coding books on their website for purchase.
