ICD-10 Code K28.9 – Gastrojejunal ulcer, unspecified as acute or chronic, without hemorrhage or perforation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K28.9 – Gastrojejunal ulcer, unspecified as acute or chronic, without hemorrhage or perforation
What it is
K28.9 identifies a gastrojejunal ulcer at the connection between the stomach and jejunum, when the record does not specify whether it is acute or chronic and there is no bleeding or perforation. Use it for a documented ulcer at this anastomotic site.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may describe epigastric or upper abdominal pain, nausea, vomiting, or evidence of ulceration on endoscopy at the gastrojejunal anastomosis.
When to use this code
Use K28.9 when the provider documents a gastrojejunal ulcer but does not state whether it is acute or chronic. It also applies when the ulcer is present without hemorrhage or perforation. If the note identifies bleeding, perforation, or a different ulcer type, code that documented condition instead.
Do not use for
Do not use this code for a gastrojejunal ulcer with hemorrhage or perforation, or when the record specifies a more detailed K28 code. Check documentation if the ulcer site is not clearly gastrojejunal.
Coding tip
Confirm both the anastomotic site and the absence of bleeding or perforation before assigning K28.9.
