CPT for ENT: Zenker's Diverticulum

CPT for ENT: Zenker's Diverticulum

Zenker’s Diverticulum is a pouch found above the cervical esophagus. It causes swallowing difficulties (Dysphagia), regurgitation, weight loss and other symptoms. When an Otolaryngologist performs open surgical excision of a Zenker’s diverticulum, he or she should report CPT code:

  • 43130 - Diverticulectomy of the hypopharynx or esophagus, with or without myotomy; cervical approach

However, with recent advances in technology, most otolaryngologists choose to perform these excisions endoscopically. Currently, there are not any codes for the endoscopic removal of Zenker’s diverticulum. In order to code properly for endoscopic removal of a Zenker’s diverticulum, the Academy recommends use of the unlisted procedure code(s):

  • •43499 - Unlisted procedure, esophagus

Do not select a CPT code that only approximates the service provided. If you are unable to find an exact description of the procedure as performed, you should report the most appropriate unlisted procedure code.
