K29.21
ICD-10-CMThis code signifies inflammation of the stomach lining caused by excessive alcohol consumption, specifically when there is evidence of active or recent bleeding. The bleeding can manifest as hematemesis, melena, or positive stool guaiac, indicating gastrointestinal hemorrhage.
Apply this code when documentation clearly links gastritis and bleeding to alcohol abuse. This includes patients presenting with upper GI bleeding symptoms and a history of heavy alcohol intake, where endoscopy confirms gastritis with erosions or ulcers. Ensure the physician explicitly states the alcoholic etiology of the gastritis.
