Summary
Axillary reverse mapping (ARM) for prevention of breast cancer-related lymphedema is considered investigational and not covered. This affects breast cancer surgery procedures where ARM is performed alongside sentinel lymph node biopsy or axillary lymph node dissection.
Action Required
Immediately: Stop billing for axillary reverse mapping procedures as they are considered investigational and will be denied. Use CPT code 38999 only for documentation purposes if performed, but expect denials. Notify surgeons performing breast cancer procedures that ARM is not covered. Update billing system to flag CPT 38999 as non-covered for this indication.
