Coding Tips
- •Verify laterality is documented as 'left' in the medical record before assigning this code.
- •Link this code with the primary cancer diagnosis code in the claim.
Clinical Significance
Secondary malignant neoplasm of the left ovary confirms metastatic cancer with left-sided laterality. As with right ovarian involvement, this finding indicates advanced disease from a distant primary and requires pathological differentiation from primary ovarian cancer. Accurate laterality documentation is critical for surgical planning and treatment monitoring.
Documentation Requirements
- ✓Primary cancer site documented and coded separately
- ✓Explicit documentation of left ovary involvement
- ✓Pathological confirmation of metastatic tumor histology
- ✓Imaging confirmation — pelvic ultrasound, CT, or MRI
- ✓Assessment for contralateral ovarian involvement
