Answer: If the surgeon excised a Zenker's diverticulum, she removed a pouch that develops in the pharynx of some patients, above the esophageal sphincter. If the surgeon performs an open procedure, report 43130 (Diverticulectomy of hypopharynx or esophagus, with or without myotomy; cervical approach).
According to an article on the AAO-HNS Web site, if the surgeon uses an endoscopic approach to remove the diverticulum, you should report an unlisted- procedure code (such as 43499 or 43289).
