ICD-10 Code K29.41 – Chronic atrophic gastritis with bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K29.41 – Chronic atrophic gastritis with bleeding
What it is
This code identifies chronic atrophic gastritis, a long-term inflammation of the stomach lining with thinning or loss of gastric glands, when bleeding is documented. Use it when the record clearly links the atrophic gastritis to bleeding.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include chronic gastritis with mucosal atrophy, endoscopic evidence of inflamed or thinned gastric mucosa, and documented upper gastrointestinal bleeding.
When to use this code
Use K29.41 when the provider documents chronic atrophic gastritis and specifies bleeding as part of the diagnosis. It is appropriate for inpatient, outpatient, or procedure notes when the bleeding is attributed to the gastritis. Check documentation if the cause of bleeding is unclear.
Do not use for
Do not use this code for gastritis without atrophy or without bleeding. Also avoid it when bleeding is from another source, such as ulcer disease or varices, unless the note clearly states chronic atrophic gastritis with bleeding.
Coding tip
Code the documented combination exactly; if bleeding is mentioned but the gastritis type is not specified, check documentation before assigning K29.41.
