ICD-10 Code K28.4 – Chronic or unspecified gastrojejunal ulcer with hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K28.4 – Chronic or unspecified gastrojejunal ulcer with hemorrhage
What it is
This code identifies a chronic or not further specified ulcer at the gastrojejunal anastomosis with bleeding. Use it when the record documents a gastrojejunal ulcer and hemorrhage, but does not specify an acute or other subtype.
Clinical signs
Findings may include upper gastrointestinal bleeding, such as hematemesis or melena, along with ulcer-related epigastric pain. Clinical features vary; refer to documentation.
When to use this code
Use K28.4 when the provider documents a chronic gastrojejunal ulcer with hemorrhage, or simply a gastrojejunal ulcer with bleeding and no more specific type. It also fits post-surgical anatomy involving a gastrojejunal connection. Check documentation if the record instead describes perforation, obstruction, or an acute ulcer.
Do not use for
Do not use this code for peptic ulcers outside the gastrojejunal site or for ulcers without documented hemorrhage. If the note specifies a different complication or another ulcer location, code that condition instead.
Coding tip
Verify both the ulcer location and the presence of hemorrhage before assigning K28.4.
