C9764 descriptor and code status

The October 2026 HCPCS Level II file describes C9764 as “Revascularization, endovascular, open or percutaneous, lower extremity artery(ies), except tibial/peroneal; with intravascular lithotripsy, includes angioplasty within the same vessel(s), when performed”. It sits in the C section (hospital outpatient prospective payment system, temporary codes), listed with the other C codes.
