0.000What This Code Means
Cancer that involves multiple overlapping areas of the right female breast rather than being confined to a single quadrant or region.
Coding Tips
- •Use this code when the tumor spans two or more distinct anatomical regions of the breast
- •Overlapping site designation may indicate more advanced local disease; ensure documentation supports this classification
Clinical Significance
Overlapping sites of the right female breast indicates a malignancy that spans multiple anatomical regions of the breast, which typically suggests a larger or more advanced tumor. This code is specifically designated for tumors that cannot be classified to a single breast subsite, carrying implications for staging, treatment planning, and prognosis.
Documentation Requirements
- ✓Confirmed female patient sex
- ✓Laterality documented as right breast
- ✓Documentation that the tumor involves two or more distinct anatomical subsites
- ✓Specific subsites involved identified in pathology or imaging
- ✓Tumor size and extent of local invasion
- ✓TNM staging and lymph node status
- ✓Histological type and receptor status
Commonly Confused Codes
C50.911 — Unspecified site of right female breast; used when the exact site is unknown, not when multiple known sites are involvedC50.411 — Upper-outer quadrant of right female breast; use when the primary site is confined to one quadrantC50.812 — Overlapping sites of left female breast; laterality errorC80.1 — Malignant neoplasm without specification of site; this is far too nonspecific when the breast is identified
