ICD-10 Code K29.51 – Unspecified chronic gastritis with bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K29.51 – Unspecified chronic gastritis with bleeding
What it is
K29.51 identifies chronic inflammation of the stomach lining when the type is not specified and bleeding is present. Use it when documentation supports chronic gastritis with bleeding but does not name a more specific form.
Clinical signs
Clinical features may include epigastric pain, nausea, dyspepsia, or evidence of upper gastrointestinal bleeding. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic gastritis and also notes bleeding, hemorrhage, or blood loss from the stomach. It is appropriate when the record does not identify a more specific gastritis subtype. If the documentation is unclear, check documentation.
Do not use for
Do not use this code for acute gastritis, peptic ulcer disease, or bleeding from another gastrointestinal source. Do not assign it when bleeding is absent or when a more specific gastritis code is documented.
Coding tip
Confirm that both chronic gastritis and bleeding are documented before assigning K29.51.
