Gastric intestnl metaplasia without dysplasia, w the antrum

This code signifies the presence of intestinal metaplasia within the antral region of the stomach, a condition where the normal gastric lining is replaced by cells resembling those found in the intestine. Importantly, this specific code indicates that there is no evidence of dysplasia, meaning the cellular changes are not yet considered precancerous.

Use this code when pathology reports confirm intestinal metaplasia confined to the gastric antrum, and explicitly state the absence of dysplasia. This diagnosis is typically made following endoscopic biopsy. Documentation should clearly specify the location (antrum) and the lack of dysplastic changes.

• Differentiate carefully from intestinal metaplasia involving other gastric sites (e.g., fundus, body) or unspecified locations.
• Ensure the pathology report explicitly rules out dysplasia; if dysplasia is present, a different code is required.
• This code is often a secondary diagnosis, accompanying codes for the underlying reason for endoscopy (e.g., chronic gastritis, dyspepsia).
