Secondary malignant neoplasm of right ovary

This code signifies the presence of a malignant tumor in the right ovary that originated from a primary cancer elsewhere in the body and subsequently spread to the ovary. It indicates a metastatic process, not a primary ovarian cancer.

Use this code when medical record documentation clearly states a secondary or metastatic malignancy affecting the right ovary. This typically occurs in patients with a known primary cancer (e.g., breast, colon, stomach) that has spread. Documentation should specify "metastatic to right ovary" or "secondary neoplasm of right ovary."

• Always sequence the primary malignant neoplasm code before this secondary code.
• Do not confuse with C56.1 (Malignant neoplasm of right ovary), which is for primary ovarian cancer.
• Ensure documentation specifies "right" ovary; if bilateral, use C79.62, or C79.60 if unspecified.
