Summary & Overview
CPT 92972: Percutaneous Coronary Lithotripsy (Add-On)
CPT code 92972 designates percutaneous coronary lithotripsy performed as an add-on to another coronary intervention to fracture vascular calcifications. As an adjunct to percutaneous coronary procedures, intravascular lithotripsy facilitates lesion preparation and device delivery in heavily calcified coronary arteries, which can affect procedural success and downstream patient outcomes. The code matters nationally as use of specialized coronary plaque modification tools grows alongside an aging population with complex coronary disease.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for intravascular coronary lithotripsy, discussion of typical sites of service (hospital catheterization laboratories and outpatient cath suites), and what to expect in billing practice when 92972 is billed as an add-on to primary coronary procedures. The publication also highlights benchmarks and policy-relevant considerations for coverage and coding alignment across major payers, and summarizes implications for procedural workflow and documentation. Data not available in the input where payer-specific rates, taxonomies, ICD-10 pairings, and related code lists would normally appear.
Billing Code Overview
CPT code 92972 describes an add-on percutaneous coronary lithotripsy procedure used to break up calcifications in a coronary vessel. The service is performed through a percutaneous (through the skin) approach and is reported in addition to another primary coronary procedure when intravascular lithotripsy is used to treat vascular calcification.
-
Service type: Percutaneous intravascular coronary lithotripsy (add-on interventional cardiac procedure)
-
Typical site of service: Hospital catheterization laboratory or outpatient cardiac catheterization suite (percutaneous coronary intervention setting)

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with severe, focal coronary artery calcification presenting for percutaneous coronary intervention (PCI) due to symptomatic ischemia or an acute coronary syndrome. The patient arrives to the cardiac catheterization laboratory after coronary angiography has identified heavily calcified lesion(s) that impede balloon expansion or stent delivery. Under conscious sedation or general anesthesia in an outpatient or inpatient cardiac catheterization suite (or hybrid operating room), the interventional cardiology team advances a coronary guidewire and specialized intravascular lithotripsy balloon to the target lesion via a percutaneous arterial approach (commonly femoral or radial). The provider delivers lithotripsy pulses to fracture intimal and medial calcium, facilitating subsequent balloon angioplasty and stent implantation. Typical workflow steps include pre-procedure consent and imaging review, vascular access and anticoagulation, intravascular imaging (IVUS or OCT) to confirm calcium burden when indicated, delivery of lithotripsy (CPT 92972 as an add-on to the primary PCI or atherectomy service), post-lithotripsy angioplasty/stent placement, hemostasis, and recovery. Standard documentation includes indication, lesion location, devices used, number of lithotripsy pulses, immediate angiographic result, complications if any, and disposition.
