Diverticulum of esophagus, acquired

This code represents an acquired outpouching or sac-like protrusion from the wall of the esophagus, which is not present at birth. These diverticula can occur anywhere along the esophageal tract and may result from increased intraluminal pressure or motility disorders.

Assign this code when documentation specifies an acquired esophageal diverticulum, such as a Zenker's, midesophageal (traction), or epiphrenic diverticulum. This code is appropriate for symptomatic or asymptomatic acquired diverticula identified through endoscopy, barium swallow, or other imaging studies.

• Differentiate carefully between acquired and congenital esophageal diverticula; the latter is excluded.
• Look for specific anatomical locations (e.g., Zenker's, epiphrenic) to confirm an acquired origin.
• Code any associated symptoms (e.g., dysphagia, regurgitation) or complications (e.g., diverticulitis) separately.
