Zenker’s Diverticulectomy
A patient with Zenker’s diverticulum and dysphagia presented for diverticulectomy. Prior to the procedure, a laryngoscopy and hypopharyngoscopy revealed a large deep Zenker’s diverticulum, along with a thick hypertrophic cricopharyngeal bar. Endoscopic endocautery was used to create a horizontal mucosal incision over the cricopharyngeal bar and the mucosa was elevated away from the bar. The central portion of the cricopharyngeus muscle was then resected, followed by excision of the Zenker’s sac. The mucosa was then stitched closed. In the Second Quarter 2020 issue of Coding Clinic, the root operation “Division” was advised for Zenker’s diverticulectomy, however, this procedure appears to be performed using a different surgical technique. What are the appropriate root operations for this procedure? ...

Article Overview
This article reviews coding considerations for a Zenker’s diverticulectomy in ICD-10-PCS. It focuses on the operative technique, the relationship of the procedure steps to root operation selection, and the relevance of prior Coding Clinic guidance for coders working with ENT and inpatient procedure coding.
Why This Topic Matters
Zenker’s diverticulectomy can involve more than one operative step, so accurate procedure coding depends on understanding how the surgery is documented and how that documentation maps to ICD-10-PCS root operations. The article is relevant to facility coders, CDI specialists, and coding educators who need to interpret operative reports and compare them with published coding guidance.
