ICD-10 Code K28.6 – Chronic or unspecified gastrojejunal ulcer with both hemorrhage and perforation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K28.6 – Chronic or unspecified gastrojejunal ulcer with both hemorrhage and perforation
What it is
K28.6 identifies a gastrojejunal ulcer that is chronic or unspecified and has both bleeding and perforation. Use it when documentation clearly states this combined complication at the gastrojejunal anastomosis.
Clinical signs
Clinical features vary; refer to documentation. Typical records may describe upper gastrointestinal bleeding and evidence of a perforated ulcer, often confirmed by endoscopy, imaging, or operative findings.
When to use this code
Use K28.6 when the provider documents a chronic or unspecified gastrojejunal ulcer with both hemorrhage and perforation. It is appropriate after gastric surgery when the ulcer is specifically located at the gastrojejunal site and both complications are reported.
If the note mentions only bleeding, only perforation, or a different ulcer site, you should not choose this code. Check documentation for the exact ulcer type, chronicity, and complication details before assigning it.
Do not use for
Do not use this code for acute ulcers, ulcers without both hemorrhage and perforation, or ulcers at a different gastrointestinal location. Check documentation if the record is unclear.
Coding tip
Confirm that both hemorrhage and perforation are documented; if one is missing, select the more specific matching code.
