CPT 93306: Transthoracic Echocardiography, Complete 2D

Medicare pays $136 and commercial payers pay $639 on average nationally for this procedure.

CPT code 93306 describes a complete transthoracic echocardiogram using transducers to obtain two‑dimensional (2D) images through the chest wall to evaluate the anatomy and function of all four heart chambers, valves, adjacent aorta, and cardiac walls; service type: diagnostic cardiac imaging (complete transthoracic echocardiography); typical site of service: outpatient or inpatient echocardiography lab or hospital imaging department performed at the chest wall (transthoracic).

National Reimbursement Benchmarks

Medicare’s national mean of $136.50 sits well below the BUCA average commercial mean of $639.50, indicating a large gulf between federal reimbursement and this commercial benchmark. This gap reflects how commercial arrangements, represented here by BUCA’s mean, can be multiple times higher than Medicare for CPT 93306, which may influence overall revenue mixes when payer mix skews toward commercial coverage.

Dispersion measured as the interquartile range (P75 minus P25) highlights differing variability across payers: Blue Cross Blue Shield shows the widest IQR at $406.80 ($1,168.80 - $780.60), followed by BUCA at $263.00 ($791.80 - $494.90). The tightest IQRs are Aetna at $162.90 ($247.30 - $84.00) and Cigna at $197.70 ($314.40 - $121.70); UnitedHealth Group’s IQR is $185.20 ($305.20 - $132.00). These ranges summarize how concentrated or spread out negotiated rates are across payers.

Clinical & Coding Specifications

Clinical Context

A 62-year-old patient with a history of treated breast cancer presents for routine surveillance and evaluation of new exertional dyspnea. The oncology team requested a transthoracic echocardiogram prior to initiation of adjuvant chemotherapy agents with known cardiotoxicity and for baseline cardiac function assessment. The patient arrives at the hospital outpatient imaging center. A sonographer performs a transthoracic two-dimensional echocardiogram using transducers across the chest wall to obtain views of the left and right ventricles, atria, valves, adjacent ascending aorta, and pericardial space. Images include standard parasternal long- and short-axis, apical two-, three-, and four-chamber views, and subcostal windows as tolerated. The interpreting physician reviews images, measures chamber sizes, left ventricular ejection fraction, valve morphology and function, and documents any pericardial effusion or wall motion abnormalities. The study includes both a professional component (interpretation and report by the physician) and a technical component (image acquisition and equipment use). Typical workflow steps: referral or order from oncology or primary care, scheduling at outpatient echocardiography suite or hospital diagnostic imaging, pre-scan screening and consent, sonographer acquisition of images and Doppler as indicated, physician review and formal report, and communication of results to referring provider. Typical sites of service include hospital outpatient imaging departments, freestanding cardiac ultrasound centers, and ambulatory clinic-based imaging suites. Typical clinical indications include baseline pre-chemotherapy assessment (Z01.818), therapeutic drug monitoring encounters (Z51.81), post‑treatment surveillance (Z08), and infectious or inflammatory cardiac conditions such as tuberculosis of the heart (A18.84), diphtheritic cardiomyopathy (A36.81), meningococcal pericarditis (A39.53), and sepsis-related myocarditis or septic cardiomyopathy (e.g., A40.0, A40.1).
