Summary & Overview
CPT 93307: Two-Dimensional Transthoracic Echocardiogram
CPT code 93307 represents a two-dimensional transthoracic echocardiogram (2D TTE), a noninvasive ultrasound study used to visualize heart chambers, valves, blood flow, and cardiac activity. This imaging service has both professional and technical components and is widely used across inpatient and outpatient settings for diagnostic cardiac evaluation. Nationally, 2D TTE is a common front-line cardiac imaging modality that informs clinical decisions ranging from heart failure management to valvular disease assessment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage considerations, common billing modifiers, and the typical sites of service for CPT code 93307.
This publication provides clinical context for the service, national benchmarking information where available, and relevant policy and billing considerations affecting reimbursement for the professional and technical components. It outlines common use cases for the code, common modifiers used in practice, and notes where data is not available in the input. The goal is to offer a concise reference for payers, providers, and billing professionals to understand the role and billing characteristics of CPT code 93307 in the current clinical and administrative environment.
Billing Code Overview
CPT code 93307 describes a two-dimensional (2D) transthoracic echocardiogram performed by a provider using transducers on the chest wall to visualize cardiac structures. The study includes assessment of heart chambers, valves, blood flow, and overall cardiac activity, capturing real-time 2D images for diagnostic interpretation.
Service Type: Diagnostic imaging — transthoracic echocardiography (2D TTE)
Typical Site of Service: Outpatient imaging centers, hospital outpatient departments, and inpatient hospital units where bedside transthoracic echocardiography is performed
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with a history of hypertension and progressive exertional dyspnea presents to the outpatient cardiology clinic for evaluation of suspected heart failure. The cardiologist orders a transthoracic echocardiogram to assess left ventricular function, chamber sizes, valvular structure and function, and to evaluate for pericardial effusion. The patient is escorted to the echocardiography suite where a cardiac sonographer performs a standard two-dimensional transthoracic echocardiogram using multiple transducer positions on the chest wall. The study includes real-time 2D imaging of cardiac chambers and valves, Doppler assessment of flow velocities, and acquisition of standard views. The interpreting cardiologist performs the professional component interpretation and documents measurements (ejection fraction, chamber dimensions, valve gradients, regurgitation severity) and a formal report. The technical component includes equipment, sonographer time, and image acquisition. The service is coded to 93307 with the appropriate modifier to indicate the professional, technical, or global component depending on billing responsibilities.
