CPT 93306: Transthoracic 2D Echocardiogram, Comprehensive
Headline: CPT code 93306: Comprehensive Transthoracic 2D Echocardiogram
Lead: CPT code 93306 defines a comprehensive transthoracic two‑dimensional echocardiogram that evaluates chamber size, valve structure and function, adjacent aortic segments, and myocardial walls. This diagnostic imaging procedure has both professional and technical components and is commonly used in cardiac diagnosis, management, and follow‑up.
CPT code 93306 matters nationally because echocardiography is a frontline, noninvasive tool for diagnosing heart disease, guiding therapy, and monitoring treatment response across inpatient and outpatient settings. The code captures a broad, comprehensive 2D assessment that influences clinical decision making for cardiology, internal medicine, and perioperative care.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service and typical sites of service, the code’s place among related echocardiography services, and the context needed for coding and billing workflows. The publication summarizes common clinical indications, payer coverage considerations, and related procedure codes to help administrators, coders, and clinicians understand where 93306 fits in a cardiac imaging portfolio.

The service includes evaluation of the anatomy and function of all four heart chambers, cardiac valves, the adjacent aorta, and the myocardium.
Service type: Diagnostic imaging – transthoracic echocardiography with comprehensive 2D assessment
Typical site of service: Outpatient imaging suite, hospital radiology or cardiology department, or ambulatory clinic with echocardiography capability
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.
