    CPT 0361T: CT Heart with Contrast and 3D Postprocessing During Catheterization

    Commercial payers pay $63 on average nationally for this procedure.

    CPT code 0361T describes a multi-slice computed tomography (CT) of the heart performed with intravenous contrast and including 3D image postprocessing, specifically when performed during cardiac catheterization; service type: diagnostic cardiac CT with advanced postprocessing, typical site of service: cardiac catheterization laboratory or interventional radiology suite.

    National Reimbursement Benchmarks

    National commercial rates for CPT 0361T cluster around an average of $63.20 under BUCA, with BUCA’s interdecile spread modest and the interquartile range running from $55.30 (P25) to $69.50 (P75), a $14.20 IQR. Cigna aligns closely with BUCA on central tendency—Cigna’s mean is $63.20 and median $68.40—but Cigna also shows a full min/max spread from $55.30 to $69.50, indicating similar central levels with the same high-end cap.

    Comparing dispersion, BUCA’s IQR is $14.20 (P75 $69.50 minus P25 $55.30), and Cigna’s IQR is the same given matching quartiles, so neither payer is tighter or wider than the other on interquartile dispersion. Cigna’s available min/max values reveal the same range endpoints observed in BUCA, so variability around the median is comparable across these commercial payers for this code.

    Clinical & Coding Specifications

    Clinical Context

    A 64-year-old male with known coronary artery disease and prior aortocoronary bypass grafting (Z95.1) presents to the cardiac catheterization lab with exertional chest pain and intermittent angina (I20.9) and a recent episode concerning for non–ST-elevation myocardial infarction (I21.9) with elevated troponin and persistent symptoms despite medical therapy. The interventional cardiology team plans invasive coronary angiography via right radial access. During the same session, the team performs a contrast-enhanced multi-slice cardiac CT with 3D postprocessing (0361T) to evaluate native coronary anatomy, graft patency, and complex spatial relationships prior to potential percutaneous coronary intervention.

    The clinical workflow: patient consent and pre-procedure allergy/renal assessment; intravenous contrast and hemodynamic monitoring in the cath lab; performance of invasive angiography (catheter placement and diagnostic cine runs); while vascular access remains established and the patient is hemodynamically stable, acquisition of gated multi-slice CT heart with iodinated contrast and immediate 3D postprocessing to assist in procedural planning; post-imaging review by interventional cardiologist and diagnostic radiologist to inform intraprocedural decisions such as stent sizing (92928), intravascular physiologic assessment (93571), or additional catheter-based interventions. Typical site of service is the hospital cardiac catheterization laboratory or an ambulatory surgical center with CT capability. Service type: image-guided diagnostic CT performed intra-procedurally during cardiac catheterization.
