ICD-10 Code K31.A14 – Gastric Intestinal Metaplasia Without Dysplasia, Involving the Cardia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K31.A14 – Gastric intestinal metaplasia without dysplasia, involving the cardia
What it is
This code identifies intestinal metaplasia in the gastric cardia without dysplasia. It means the normal stomach lining has changed to a more intestine-like pattern in the cardia region.
Clinical signs
Findings are usually based on endoscopy and biopsy, not symptoms alone. Clinical features vary; refer to documentation for the pathologic description and confirmation that dysplasia is absent.
When to use this code
Use K31.A14 when the pathology report specifically states gastric intestinal metaplasia without dysplasia and identifies the cardia as the site. Use it for documented biopsy-confirmed cases, including follow-up evaluations of known lesions.
Do not assign it from nonspecific gastritis, reflux, or a history of metaplasia unless the current record confirms this diagnosis. If the site or dysplasia status is unclear, check documentation.
Do not use for
Do not use this code for intestinal metaplasia with dysplasia, or when the biopsy does not specify the cardia. Avoid using it for general gastric metaplasia without site detail.
Coding tip
Code only when both location and “without dysplasia” are clearly documented in the pathology report.
