HCPCS C1724: Catheter for Transluminal Rotational Atherectomy

HCPCS Level II code C1724 designates a catheter for transluminal rotational atherectomy, a device used in endovascular procedures to remove atherosclerotic plaque from vessels. This code is relevant nationally for hospitals and ambulatory surgical centers performing peripheral and coronary atherectomy procedures, and for payers and providers managing coverage, billing, and device utilization.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for rotational atherectomy catheters, typical sites of service, and the payer landscape considered. The publication outlines common billing modifiers associated with this service (input provided), and identifies where input data is not available.

The content provides benchmarks and policy-relevant information where available, clarifies coding nomenclature for device billing, and summarizes typical clinical scenarios for use of rotational atherectomy catheters. It is intended to help billing managers, revenue cycle staff, and clinical leaders understand the role of C1724 in procedure coding and payer interactions at a national level.

Clinical & Coding Specifications

Clinical Context

A typical patient is an older adult with symptomatic peripheral arterial disease (PAD) causing lifestyle-limiting claudication or critical limb ischemia with focal atheromatous or calcified plaque in a peripheral artery (femoral, popliteal, or tibial). The patient often presents with exertional leg pain, nonhealing ischemic foot ulcer, or rest pain despite medical therapy and supervised exercise. Vascular surgery or interventional cardiology evaluates the patient with a focused vascular history, physical exam including pulse and wound assessment, and noninvasive testing such as ankle–brachial index (ABI) and duplex ultrasound. If imaging shows focal, eccentric, or heavily calcified plaque unsuitable for simple angioplasty or when atherectomy is needed for plaque debulking, the patient proceeds to angiography with possible transluminal rotational atherectomy using a catheter coded as C1724.

The clinical workflow includes informed consent, percutaneous arterial access (commonly common femoral artery), diagnostic angiography to define lesion morphology and length, intraprocedural anticoagulation, and device selection. The rotational atherectomy catheter is advanced over a guidewire to the target lesion and used to debulk plaque. Adjunctive therapies—such as percutaneous transluminal angioplasty or stent placement—may follow based on residual stenosis. Post-procedure care includes hemostasis (manual compression, closure device), observation for access site complications, assessment of distal perfusion, and discharge planning with antiplatelet therapy and vascular risk factor modification.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when the transluminal atherectomy requires substantially greater work than typical due to complexity (extensive plaque burden, lengthy procedure).
`23`	Unusual anesthesia	Use when general anesthesia is required for medical reasons rather than typical monitored anesthesia care.
`51`	Multiple procedures	Use when multiple distinct procedures are billed during the same session (e.g., atherectomy plus diagnostic angiography billed separately when applicable).
`52`	Reduced services	Use if the atherectomy is attempted but only partially performed or less than full service delivered.
`53`	Discontinued procedure	Use when the procedure is started but halted due to a patient-related or system reason before completion.
`62`	Two surgeons	Use when two surgeons from different specialties perform distinct portions of the procedure and both are required.
`80`	Assistant surgeon	Use when an assistant surgeon is present and performs assisting duties during the procedure (institutional guidelines apply).
`81`	Minimum assistant surgeon	Use when a surgeon assistant performs a limited assisting role as defined by payer policy.
`82`	Assistant surgeon when qualified resident not available	Use when an assistant is needed and a qualified resident is not available.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services	Use when these nonphysician practitioners perform or assist with the service as allowed by payer rules.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures	Use when the physician directs concurrent anesthesia services for the procedure.
`QX`	CRNA service: with medical direction by a physician	Use when a certified registered nurse anesthetist provides anesthesia under physician direction.
`QY`	Medical direction of one certified registered nurse anesthetist by an anesthesiologist	Use when the anesthesiologist medically directs one CRNA for the procedure.
`FY`	Partial hospitalization or partial services (ancillary)	Use rarely for hospital-based reporting when applicable to ancillary service billing (payer-specific).

Taxonomy Code	Specialty	Notes
`208100000X`	Vascular Surgery	Primary specialty performing peripheral atherectomy procedures and vessel management.
`207RG0300X`	Interventional Cardiology	Performs peripheral interventions including atherectomy in some centers.
`207T00000X`	Interventional Radiology	Frequently performs endovascular atherectomy and angiographic imaging.
`363A00000X`	Anesthesiology	Provides sedation or anesthesia for complex cases when required.
`223Z00000X`	Physician Assistant	Common procedural support in endovascular suites under supervision.
