Answer: A pouch that forms at the back of the throat at the area connecting the pharynx and the esophagus is known as Zenker's diverticulum. The most common symptom of this condition is difficulty in swallowing food. It also causes choking, feeling mucus collecting in the throat, hoarseness, or bad breath. You would report Zenker's diverticulum with 530.6 (Diverticulum of esophagus acquired).

An otolaryngologist's treatment for Zenker's diverticulum usually involves open surgical excision. Use 43130 (Diverticulectomy of hypopharynx or esophagus, with or without myotomy; cervical approach) to report this procedure.

Alternative: Some otolaryngologists opt to perform the excisions endoscopically. In this case, you should bill 43289 (Unlisted laparoscopy procedure, esophagus).
