What This Code Means

Cancer that involves multiple areas of the right 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 right male breast
  • Ensure laterality is clearly documented as right; if unspecified, use C50.829 instead

Clinical Significance

Overlapping sites of the right male breast indicates a malignancy that spans multiple breast regions in a male patient. Given the smaller amount of breast tissue in males, overlapping site designation may suggest locally advanced disease at the time of diagnosis, which is consistent with the typically later presentation of male breast cancer.

Documentation Requirements

  • Confirmed male patient sex
  • Laterality documented as right breast
  • Documentation that the tumor involves two or more breast subsites
  • Histological type and grade
  • TNM staging and extent of local invasion
  • Receptor status and treatment plan
  • Assessment of chest wall involvement if applicable
