ICD-10 Code K26.7 – Chronic duodenal ulcer without hemorrhage or perforation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K26.7 – Chronic duodenal ulcer without hemorrhage or perforation
What it is
This code identifies a long-standing duodenal ulcer in the first part of the small intestine. It applies when the ulcer is chronic and there is no documented bleeding or perforation.
Clinical signs
Typical findings include recurrent upper abdominal pain, dyspepsia, or symptoms that improve and worsen over time. Clinical features vary; refer to documentation.
When to use this code
Use K26.7 when the record clearly states a chronic duodenal ulcer and specifically excludes hemorrhage and perforation. It fits outpatient, inpatient, or problem-list documentation when the diagnosis is confirmed and current.
Choose this code when the provider documents a chronic ulcer of the duodenum without acute complications. Check documentation if the note mentions bleeding, perforation, or another ulcer type.
Do not use for
Do not use this code if the ulcer has active bleeding or perforation, or if the site is gastric rather than duodenal. Check documentation.
Coding tip
Confirm both the anatomic site and the absence of hemorrhage or perforation before assigning K26.7.
