Malignant neoplasm of jejunum

This code signifies the presence of a cancerous tumor originating in the jejunum, the middle section of the small intestine. It indicates a primary malignant growth rather than a metastatic lesion from another site.

Apply this code when documentation clearly states a primary malignant neoplasm of the jejunum. This diagnosis is typically established through biopsy and histopathological examination. Use for patients undergoing treatment for jejunal adenocarcinoma, lymphoma, or other primary malignant tumors of this specific intestinal segment.

• Ensure documentation specifies "jejunum" and not a more general "small intestine" or another specific segment like the duodenum or ileum.
• Distinguish between primary malignancy and metastatic disease; this code is for primary only.
• Confirm the malignancy is active; if the patient is status post-resection with no evidence of disease, a history code may be more appropriate.
