ICD-10 Code K25.3 – Acute gastric ulcer without hemorrhage or perforation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K25.3 – Acute gastric ulcer without hemorrhage or perforation
What it is
K25.3 identifies an acute ulcer in the stomach lining without bleeding or perforation. Use it when the record documents a gastric ulcer that is newly active or acute, and no complication is reported.
Clinical signs
Clinical features may include epigastric pain, nausea, vomiting, or dyspepsia. Endoscopy or other documentation should confirm a gastric ulcer; if uncertain, clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents an acute gastric ulcer and specifically states there is no hemorrhage and no perforation. It also fits when the chart clearly describes an uncomplicated stomach ulcer without those complications. If the note is incomplete, check documentation.
Do not use for
Do not use K25.3 if the ulcer is chronic, bleeding, perforated, or described as gastric erosion rather than ulcer. Do not assign it when the site is duodenal or unspecified; check documentation.
Coding tip
Verify both the ulcer site and the absence of hemorrhage or perforation before assigning K25.3.
