Gastric intestinal metaplasia with dysplasia, unspecified

This code signifies the presence of intestinal metaplasia within the stomach lining that also exhibits dysplastic changes, where the specific grade or type of dysplasia is not documented. Intestinal metaplasia is a precancerous condition where the gastric mucosa is replaced by cells resembling those of the intestine. Dysplasia indicates abnormal cell growth, further increasing cancer risk.

Use this code when pathology reports confirm gastric intestinal metaplasia with dysplasia, but the pathologist does not specify the grade (e.g., low-grade, high-grade) or type of dysplasia. Documentation must explicitly state both "gastric intestinal metaplasia" and "dysplasia" without further specificity.

• Do not use if the grade of dysplasia (e.g., low-grade, high-grade) is specified; use more specific codes from the K31.A2 series.
• Ensure the documentation clearly links the intestinal metaplasia to the stomach.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is an incidental finding or comorbidity.
