ICD-10 Code K29.2 – Alcoholic gastritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K29.2 – Alcoholic gastritis
What it is
K29.2 identifies gastritis caused by alcohol use. Use it when the record links gastric inflammation to alcohol, rather than to infection, medication, or another documented cause.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe epigastric pain, nausea, vomiting, indigestion, or gastric irritation in the setting of alcohol use.
When to use this code
Use K29.2 when the provider documents alcoholic gastritis, alcohol-induced gastritis, or gastritis due to alcohol. It may also fit when the assessment clearly attributes gastritis to alcohol exposure. If the cause is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for gastritis from NSAIDs, H. pylori, or other specified causes. Avoid it when alcohol use is present but not documented as the cause of the gastritis.
Coding tip
Look for explicit provider wording that connects gastritis to alcohol; presence of alcohol use alone is not enough.
