Question: Georgia Subscriber Answer: As you suggested, 43659 (Unlisted laparoscopy procedure, stomach) is the proper code to report. Why: Unfortunately, coding for lap procedures hasn't kept up with technology. If no precise procedure or service code exists, you should report the service "using the appropriate unlisted procedure or service code," state the CPT Instructions for Use in the CPT manual. CPT includes unlisted-procedure codes to allow you to report procedures for which there is no specific CPT descriptor available. When there is an established CPT code that accurately describes the services your surgeon performs, you should report that code rather than an unlisted code.
