What This Code Means

Cancer that involves multiple areas of the left breast in a male patient. This occurs when the tumor spans across different regions of the breast tissue.

Coding Tips

•Use this code when documentation indicates cancer affecting more than one specific site in the left male breast
•Ensure laterality is clearly documented as left; if unspecified, use C50.829 instead

Clinical Significance

Overlapping sites of the left male breast indicates locally advanced breast cancer spanning multiple anatomical regions. Male breast cancer with overlapping site involvement may present with direct chest wall or skin involvement due to the thin layer of breast tissue in males. This code captures the extent of local disease for surgical and radiation planning.

✓Laterality documented as left breast
✓Documentation of tumor spanning multiple breast subsites
