Gastric intestnl metaplasia without dysplasia, w mult sites

This code signifies the presence of intestinal metaplasia within the stomach lining, affecting more than one anatomical location, without any evidence of abnormal cell growth (dysplasia). Intestinal metaplasia is a precancerous condition where the normal gastric mucosa is replaced by cells resembling those of the intestine.

Use this code when diagnostic endoscopy with biopsy confirms multifocal gastric intestinal metaplasia and the pathology report explicitly states the absence of dysplasia. This code is appropriate for surveillance and management of patients at increased risk for gastric adenocarcinoma.

• Ensure the pathology report specifically mentions "multiple sites" or "multifocal" involvement of intestinal metaplasia.
• Do not use this code if dysplasia is present; a more specific code indicating dysplasia should be selected.
• Distinguish from K31.A11 (gastric intestinal metaplasia, unspecified site) when the documentation clearly indicates multiple sites.
