Summary & Overview
HCPCS C7533: Percutaneous Coronary Angioplasty with Intravascular Brachytherapy Device
HCPCS Level II code C7533 denotes a percutaneous transluminal coronary angioplasty (PTCA) of a single major coronary artery or branch with transcatheter placement of a radiation delivery device for subsequent intravascular brachytherapy. This code captures a combined interventional cardiology procedure used when post-angioplasty radiation is planned to reduce restenosis risk. Nationally, the code is significant for hospitals and interventional cardiology groups due to its association with specialized catheterization laboratory resources and coordination of radiation therapy devices.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when this combined PTCA and intravascular brachytherapy service is used, typical sites of care, and which payers commonly cover the service. The analysis outlines benchmarks and payment considerations, coding adjacency and billing practice notes, and recent policy or coverage updates where available. It is intended to inform coding, billing, and revenue cycle teams, as well as clinical leadership, about documentation expectations, service classification, and payer coverage patterns for this specific HCPCS Level II procedure.
Billing Code Overview
HCPCS Level II code C7533 describes percutaneous transluminal coronary angioplasty of a single major coronary artery or branch with transcatheter placement of a radiation delivery device for subsequent coronary intravascular brachytherapy. This procedure combines balloon or catheter-based dilation of a blocked coronary artery with placement of a transcatheter radiation source intended for intravascular brachytherapy delivered after angioplasty.

Service type: Percutaneous coronary intervention with intravascular brachytherapy placement

Typical site of service: Hospital-based catheterization laboratory or interventional cardiology suite
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of diffuse in-stent restenosis of a previously treated right coronary artery (RCA) presents with recurrent angina refractory to medical therapy. Coronary angiography demonstrates a focal restenotic lesion in a major coronary branch unsuitable for repeat plain balloon angioplasty alone due to high recurrence risk. The interventional cardiology team plans a percutaneous transluminal coronary angioplasty with transcatheter placement of a radiation delivery device for subsequent intravascular brachytherapy (C7533).
Pre-procedure workflow includes informed consent, antiplatelet and anticoagulation review, vascular access planning (typically femoral or radial arterial access in a catheterization laboratory), baseline hemodynamic assessment, and coronary angiography with lesion measurement. During the index procedure the operator performs balloon angioplasty and deploys a radiation delivery catheter to the target segment; radiation delivery may occur immediately or in a subsequent session per institutional protocol. Post-procedure care occurs in a monitored recovery area with access site surveillance, rhythm monitoring, and antithrombotic management. Typical site of service is the hospital catheterization laboratory (inpatient or outpatient observation) or an accredited ambulatory surgical center equipped for interventional cardiology.
