Malignant neoplasm of lesser curvature of stomach, unspecified

This code signifies a cancerous tumor located on the lesser curvature of the stomach, where the specific subsite within the lesser curvature has not been documented. It indicates a primary malignancy originating in this region of the stomach.

Use this code when documentation confirms a primary malignant neoplasm of the stomach, and the physician explicitly states it is located on the lesser curvature but does not specify a more precise anatomical location (e.g., cardia, fundus). This code is appropriate when the pathology report or operative note confirms malignancy and the lesser curvature as the site, without further detail.

• Do not use this code if a more specific subsite of the lesser curvature (e.g., cardia, pylorus) is documented; instead, select the more precise code.
• Ensure the documentation clearly states "malignant neoplasm" and "lesser curvature of stomach."
• This code is for primary malignancy; use secondary codes for metastatic disease to the stomach.
