Gastric intestinal metaplasia, unspecified

This code signifies the presence of gastric intestinal metaplasia (GIM) without further specification of its type or location. GIM is a precancerous condition where the lining of the stomach changes to resemble the lining of the intestine, often due to chronic inflammation.

Use this code when documentation confirms a diagnosis of gastric intestinal metaplasia but does not specify if it's complete or incomplete, or its exact anatomical site within the stomach. This is appropriate when the pathology report or physician's notes simply state "gastric intestinal metaplasia."

• Do not use this code if the type of intestinal metaplasia (e.g., complete or incomplete) is documented; instead, look for more specific codes.
• Ensure the documentation clearly states "gastric" intestinal metaplasia to differentiate from intestinal metaplasia in other organs.
• Consider sequencing this code after codes for underlying conditions like chronic gastritis (e.g., K29.50, K29.70) if documented as causative.
