Cancer that has spread to one or both ovaries from another part of the body, but the specific ovary is not identified.
Coding Tips
Clinical Significance
Secondary malignant neoplasm of an unspecified ovary indicates metastatic cancer has spread to an ovary but laterality is not documented. Krukenberg tumors (ovarian metastases from gastrointestinal primaries) are a classic example. Ovarian metastases require differentiation from primary ovarian cancer, which has vastly different treatment approaches and prognosis.
Documentation Requirements
- ✓Primary cancer site documented and coded separately
- ✓Laterality — right, left, or bilateral ovarian involvement
- ✓Pathological confirmation distinguishing metastatic from primary ovarian cancer
- ✓Imaging confirmation — CT, MRI, or ultrasound
- ✓Tumor markers — CA-125, CEA, CA 19-9 to help distinguish primary from metastatic
