CPT 93460: Coronary Angiography with Left and Right Heart Catheterization
CPT code 93460 denotes an invasive diagnostic coronary angiography where a catheter is advanced into both left and right heart structures and contrast dye may be injected into the left ventricle. This procedure is a cornerstone diagnostic study for detecting coronary artery stenosis, guiding revascularization decisions, and evaluating causes of ischemia or heart failure. Nationally, coronary angiography remains a high-cost, high-impact service with implications for hospital resource use and cardiovascular outcomes.
Payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and the typical care setting, comparisons to closely related angiography codes, and common billing considerations tied to procedure complexity. The content outlines where 93460 fits within the spectrum of coronary diagnostic procedures and highlights connections to related catheterization codes used when additional elements (for example, bypass graft imaging or limited catheter placement) are performed.
This publication provides actionable reference material for coding teams, clinical program managers, and revenue cycle stakeholders seeking a national-facing summary of CPT code 93460—covering clinical context, payer scope, and the coding relationships that affect case classification and charge capture.

Billing Code Overview
CPT code 93460 describes a coronary angiography procedure in which a provider performs catheter-based imaging of the heart's blood vessels. The clinician inserts tubing into an artery, typically via the groin or arm, advances the catheter into both the left and right sides of the heart, and injects radiographic dye to visualize coronary vessels. Dye may also be injected into the left ventricle when necessary. The provider supervises image acquisition and interprets the images to identify vessel narrowing or blockages and assess cardiac function.
-
Service type: Diagnostic invasive coronary angiography with catheter placement into left and right heart structures; may include left ventricular contrast injection
-
Typical site of service: Inpatient or outpatient catheterization laboratory (cardiac cath lab); procedure often performed in hospital or hospital-affiliated outpatient facilities
National Reimbursement Benchmarks
Medicare reimburses substantially less than the BUCA commercial mean: Medicare’s mean of $833.60 versus BUCA’s mean of $3,251.70 highlights a sizable gap between the public program and this commercial benchmark. Blue Cross Blue Shield and BUCA both sit well above Medicare on mean rates, while Aetna, Cigna, and UnitedHealth Group are closer to Medicare’s level though still higher on average. This spread underscores the variability between public and commercial payment levels for CPT 93460.
Examining dispersion using the interquartile range (P75–P25), Blue Cross Blue Shield has the widest spread at $4,809.40 (P75 $6,651.20 minus P25 $1,841.80), followed by UnitedHealth Group at $1,321.00 and Cigna at $1,130.90. Aetna’s IQR is $774.00, and BUCA’s is $3,168.20, while Medicare’s IQR is $789.00. These comparisons indicate Blue Cross Blue Shield and BUCA have the broadest middle-50% variability, whereas Aetna and Medicare are relatively tighter.
