About 37299: Complex inframalleolar lithotripsy angioplasty, additional vessel
Reports complex endovascular treatment of an additional inframalleolar vessel using intravascular lithotripsy with angioplasty for lower-extremity revascularization.
This add-on describes treatment of an additional vessel below the ankle during lower-extremity revascularization. Intravascular lithotripsy uses a catheter to modify calcified plaque, followed by balloon angioplasty to improve vessel flow. Vascular surgeons, interventional radiologists, and interventional cardiologists may perform the service in a hospital or outpatient procedural setting. Examples of inframalleolar vessels include pedal and plantar arteries.
Report this code only with an eligible primary procedure, typically 37298 for complex angioplasty of the first inframalleolar vessel. Use the complex category according to the applicable CPT lesion classification; document the treated vessel, lesion, lithotripsy and angioplasty performed, and that it is an additional vessel. CMS pays the add-on within the primary procedure's global period. For a bilateral procedure reported with modifier 50, CMS pays 150% of the applicable amount.
