ICD-10 Code C79.62 – Secondary malignant neoplasm of left ovary (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C79.62 – Secondary malignant neoplasm of left ovary
What it is
This code identifies metastatic cancer involving the left ovary. Use it when a primary malignancy elsewhere has spread to that ovary.
Clinical signs
Clinical features vary; refer to documentation. Patients may have imaging, pathology, or operative findings showing metastatic involvement of the left ovary.
When to use this code
Use C79.62 when the record clearly states secondary malignant neoplasm of the left ovary, or when the left ovary is documented as a metastatic site from another primary cancer. You should not assign it for a primary ovarian tumor without evidence of metastasis.
Do not use for
Do not use this code for benign ovarian disease, uncertain masses, or primary ovarian cancer. Check documentation if the laterality or metastatic origin is not clearly stated.
Coding tip
Link C79.62 to the known primary cancer code and verify laterality in the pathology, imaging, or oncology note.
