Here we go again!

New CPT procedure codes are added annually (quarterly for Category II and Category III codes), definitions of existing codes are changed, and codes we have memorized are often deleted and replaced. In addition, guidelines for code assignment are constantly revised and may be altered based upon individual insurance payer interpretation. Remember, a code must accurately represent the service performed, and a code that is "close" to the procedure performed cannot be assigned. If the service performed is not defined by an existing procedure code ( CPT Category I, II, III or HCPCS Level II), then an unlisted procedure code must be used. The forms and guidelines to request new codes or changes to procedure code descriptors are currently located on the American Medical Association website in the " CPT Process" section ( pub/category/3112.html).[1]
