Esophageal web

This code represents a thin, shelf-like protrusion of tissue that partially obstructs the lumen of the esophagus. Esophageal webs are typically congenital but can also be acquired, often associated with iron deficiency anemia (Plummer-Vinson syndrome) or other inflammatory conditions. They can cause dysphagia, particularly with solid foods.

Use this code when documentation clearly identifies an esophageal web as the patient's diagnosis. This includes webs identified via endoscopy, barium swallow studies, or other imaging, and when the web is the cause of symptoms such as dysphagia.

• Distinguish from esophageal stricture (K22.2) or ring (K22.5), which are distinct anatomical abnormalities.
• Code any associated conditions, such as iron deficiency anemia (D50.x), if documented as present.
• Ensure the documentation specifies "web" to avoid confusion with other esophageal obstructions.
