0.000What This Code Means
Cancer that develops in the central portion (middle area) of the right female breast.
Coding Tips
- •The central portion is specifically the area around the nipple; ensure documentation clearly identifies this location
- •Verify laterality is documented as right; if left or unspecified, different codes apply
Clinical Significance
Malignant neoplasm of the central portion of right female breast represents invasive breast cancer requiring staging, treatment planning, and ongoing surveillance. Breast cancer is risk-adjusted because it demands significant healthcare resources including surgery, radiation, chemotherapy, hormonal therapy, and long-term monitoring.
Documentation Requirements
- ✓Pathologic confirmation of invasive malignancy (biopsy with histologic type — ductal, lobular, etc.)
- ✓Laterality: right breast
- ✓Gender documented as female to support gender-specific code selection
- ✓Quadrant or subsite location: central portion
- ✓Tumor size (T stage) and grade
- ✓Lymph node status (N stage) — axillary, sentinel node biopsy results
- ✓Estrogen receptor, progesterone receptor, and HER2 status
- ✓Stage grouping (I-IV)
- ✓Current treatment status (active treatment, hormonal therapy, surveillance)
