Summary & Overview
HCPCS C9774: Tibial/Peroneal Revascularization with Lithotripsy and Atherectomy
HCPCS Level II code C9774 captures complex revascularization procedures of the tibial and peroneal arteries that combine intravascular lithotripsy and atherectomy, and may include angioplasty in the same vessel(s). This code is important nationally because it reflects advanced limb-salvage and peripheral arterial disease (PAD) management techniques that are increasingly used to treat distal lower-extremity occlusive disease. Payers are focused on appropriate utilization, coding specificity, and site-of-service distinctions for these resource-intensive interventions.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, typical clinical settings, and the payer mix relevant to coverage and billing. The publication summarizes national benchmarks where available, recent policy and coding considerations affecting reimbursement and coverage, and clinical context relevant to procedure selection and documentation. Practical content includes indicators for when this combined approach is reported, implications for hospital outpatient versus inpatient billing, and areas where documentation drives coding specificity.
Data not available in the input for associated taxonomies, ICD-10 diagnoses, related codes, and detailed payer policy language is noted where appropriate.
Billing Code Overview
HCPCS Level II code C9774 describes revascularization of tibial/peroneal arteries performed by endovascular, open, or percutaneous approaches that include intravascular lithotripsy and atherectomy, and include angioplasty within the same vessel(s) when performed. This procedure targets occlusive or atherosclerotic disease in the tibial and peroneal arterial distribution of the lower extremity.
Service Type: Combined endovascular and/or open peripheral arterial revascularization with adjunctive intravascular lithotripsy and atherectomy, including angioplasty within the same vessel(s)
Typical Site of Service: Hospital inpatient or hospital outpatient vascular/interventional suite, and ambulatory surgical center for appropriate cases
Clinical & Coding Specifications
Clinical Context
An elderly patient with advanced peripheral artery disease presents with lifestyle-limiting claudication and a non-healing ischemic ulcer of the foot. Noninvasive testing (ABI, duplex ultrasound) and diagnostic angiography demonstrate heavily calcified, stenotic disease of the tibial and peroneal arteries. The vascular surgery or interventional cardiology team plans an endovascular limb revascularization procedure using intravascular lithotripsy to fracture arterial calcification and atherectomy to debulk plaque, followed by balloon angioplasty and selective stent placement if needed.
The clinical workflow includes pre-procedure evaluation and consent, peri-procedural anticoagulation and imaging, sterile endovascular access (often via common femoral artery), crossing the lesion with guidewires, performing atherectomy to remove atheromatous material, applying intravascular lithotripsy to modify calcified plaque, angioplasty of the treated tibial/peroneal segments, completion angiography to confirm flow, and post-procedure monitoring for vascular complications. Typical setting is an inpatient or outpatient endovascular suite or hybrid operating room with vascular surgery or interventional cardiology staffing and vascular access/angiography capabilities.
