Summary
This policy classifies all lymphatic physiologic microsurgery procedures for treating breast cancer-related lymphedema as investigational and non-covered. A new CPT code 1019T for lymphovenous bypass will be added effective January 1, 2026, but will also be considered investigational.
Action Required
Before January 1, 2026: Billing team must update system to mark CPT code 1019T (lymphovenous bypass) as investigational/non-covered for BCBS plans. Update encounter forms to alert providers that lymphatic microsurgery procedures including lymphaticovenous anastomosis and vascularized lymph node transfer are not covered. Use CPT 38999 for unlisted lymphatic procedures only with proper documentation, but expect denials for investigational services.
