Answer: This procedure (43848, Revision of gastric restrictive procedure for morbid obesity [separate procedure]) has two anesthesia coding options - 00790 (Anesthesia for intraperitoneal procedures in upper abdomen including laparoscopy; not otherwise specified) and 00797 (... gastric restrictive procedure for morbid obesity).
Your best option is to use code 00797, because the physician still performs a banding procedure for the obesity.
