Malignant neoplasm of greater curvature of stomach, unspecified

This code identifies a cancerous tumor originating in the greater curvature of the stomach, where the specific type or extent of the malignancy is not documented. It indicates a primary gastric adenocarcinoma or other malignant neoplasm located along the longer, convex border of the stomach.

Use this code when the physician's documentation clearly states a malignant neoplasm of the greater curvature of the stomach, but no further specificity regarding the histological type or precise sub-site (e.g., fundus, body) is provided. This code is appropriate when pathology reports confirm malignancy but lack detailed classification, or when clinical notes only specify the anatomical location of the tumor.

• Ensure documentation specifies "greater curvature" and "malignant neoplasm." If "lesser curvature" is documented, a different code is required.
• Avoid using this code if a more specific histological type (e.g., adenocarcinoma, lymphoma) or precise sub-site within the greater curvature is known; always code to the highest level of specificity.
• This is a primary malignancy code; do not use for metastatic disease to the stomach.
