Malignant neoplasm of other specified sites of large intestine

This code signifies a primary malignant tumor originating in a specific, but less common, location within the large intestine that is not otherwise classified. This includes sites like the splenic flexure, hepatic flexure, or transverse colon, which are distinct from the more frequently coded ascending, descending, or sigmoid colon.

Apply this code when documentation clearly identifies a primary adenocarcinoma or other malignant neoplasm located in an "other specified" part of the large intestine, such as the transverse colon or a flexure. This code is appropriate when the physician's notes specify a site that falls outside of the more granular codes for specific large intestine segments.

• Ensure the documentation specifies a primary malignancy; metastatic disease to the large intestine would be coded differently.
• Avoid using this code if a more specific ICD-9-CM code exists for the documented large intestine site (e.g., ascending colon, sigmoid colon).
• Review pathology reports and operative notes carefully for precise tumor location to ensure accurate code assignment.
