ICD-10 Code K26.2 – Acute duodenal ulcer with both hemorrhage and perforation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K26.2 – Acute duodenal ulcer with both hemorrhage and perforation
What it is
This code identifies an acute duodenal ulcer that is both bleeding and perforated. Use it when the ulcer is in the duodenum and documentation confirms both complications.
Clinical signs
Typical findings may include upper gastrointestinal bleeding and signs of a perforated ulcer, such as sudden abdominal pain or peritoneal irritation. Clinical features vary; refer to documentation.
When to use this code
Use K26.2 when the record clearly states an acute duodenal ulcer with hemorrhage and perforation. You may also use it when the clinician documents both complications together, even if the note uses equivalent wording.
Check documentation if the site is not duodenal, if the ulcer is chronic, or if only bleeding or only perforation is documented. The code requires both complications to be present.
Do not use for
Do not use this code for gastric ulcers, peptic ulcers without duodenal location, or ulcers with only hemorrhage or only perforation. Check documentation.
Coding tip
Confirm the ulcer site and both complications in the provider note before assigning K26.2.
