Secondary malignant neoplasm of left ovary

This code signifies the presence of a metastatic cancerous tumor that has spread to the left ovary from a primary cancer site elsewhere in the body. It indicates that the left ovary is not the origin of the malignancy but rather a site of secondary involvement.

Apply this code when documentation clearly states a malignant neoplasm in the left ovary is secondary or metastatic. This typically occurs in patients with a known primary cancer (e.g., breast, colon, stomach) that has spread. Pathology reports confirming metastatic disease to the left ovary are key supporting documentation.

• Always sequence the primary malignant neoplasm first, followed by this code for the secondary site.
• Distinguish carefully from primary ovarian cancer; this code is exclusively for metastatic disease.
• Ensure laterality is explicitly documented (left ovary) to avoid using an unspecified or right-sided code.
