Endovascular revascularization
About 37279: Additional femoropopliteal intravascular lithotripsy
Reports additional intravascular lithotripsy treatment in the same femoral or popliteal artery, with angioplasty included when performed.
This add-on describes additional intravascular lithotripsy treatment in a femoral or popliteal artery. The catheter-based technique uses sonic pressure waves to modify calcified plaque and may be paired with balloon angioplasty. Vascular surgeons and interventional radiologists typically perform these procedures in an endovascular suite or operating room as part of lower-extremity revascularization.
Report 37279 only with its primary procedure, 37278, when the additional same-artery treatment is supported by the operative report. Documentation should identify the treated artery and describe the intravascular lithotripsy performed; angioplasty is included when performed. CMS pays this add-on within the primary procedure’s global period. For bilateral reporting, CMS pays modifier 50 at 150%.
