Esophageal obstruction

This code identifies a blockage or narrowing within the esophagus that is not present at birth. This obstruction can impede the passage of food and liquids from the pharynx to the stomach, leading to symptoms like dysphagia, regurgitation, and weight loss. The underlying cause can be varied, including foreign bodies, tumors, or inflammation.

Assign this code when documentation indicates an acquired esophageal obstruction, stricture, or stenosis. This includes blockages due to foreign bodies, benign or malignant neoplasms, or inflammatory processes. Ensure the physician's notes clearly differentiate an acquired condition from a congenital one.

• Always review documentation to confirm the obstruction is acquired, not congenital, to avoid miscoding with Q39.3.
• If a foreign body is the cause, code the foreign body (T18.1-) as the primary diagnosis, with this code as a secondary diagnosis.
• When a neoplasm causes the obstruction, sequence the neoplasm code first, followed by this code.
