Question: North Carolina Subscriber Answer: Usually, a gastroenterologist or surgeon would perform the Secca procedure on an outpatient basis using conscious sedation and a local anesthetic. You will not find a specific CPT® code describing this procedure. It is likely that a practice would use 46999 (Unlisted procedure, anus) to report it. However, in 2004, CMS created a specific HCPCS code for this procedure when performed on Medicare patients in outpatient facilities: C9716 (Creations of thermal anal lesions by radiofrequency energy).
