Summary & Overview
HCPCS C8930: Transthoracic Echocardiography With Contrast, Stress
HCPCS Level II code C8930 represents transthoracic echocardiography performed with contrast, or performed without contrast followed by contrast, with real-time 2D imaging (including m-mode when performed) during rest and cardiovascular stress testing, and includes continuous ECG monitoring with physician supervision. This service is a key diagnostic tool for evaluating cardiac function under stress and is widely used in hospitals and outpatient imaging settings to assess ischemia, valvular function, and ventricular performance.
The analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how C8930 is defined clinically, typical sites of service, common billing modifiers, and the types of documentation and reporting bundled into the code. The publication outlines benchmark contexts and payer coverage considerations relevant to billing and coding teams, revenue cycle managers, and clinical service leaders.
Readers will learn: the clinical scope of C8930, where the service is typically delivered, which payers commonly cover the service, and which operational elements (imaging, ECG monitoring, physician supervision) are included in the code definition. Data not available in the input will be noted as such in appropriate sections.
Billing Code Overview
HCPCS Level II code C8930 describes a transthoracic echocardiography performed with or followed by contrast, with real-time two-dimensional imaging and m-mode recording when performed. The service includes assessment during rest and cardiovascular stress testing (treadmill, bicycle exercise, and/or pharmacologically induced stress), and encompasses continuous electrocardiographic monitoring with physician supervision. The description specifies both contrast and non-contrast approaches when contrast is added after an initial non-contrast study.
Service Type: Diagnostic cardiac imaging with stress testing (transthoracic echocardiography with contrast)
Typical Site of Service: Hospital outpatient departments, outpatient imaging centers, and ambulatory surgical centers where cardiovascular stress testing and supervised echocardiography are performed
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with exertional dyspnea and a history of hypertension and hyperlipidemia is referred for a stress transthoracic echocardiogram to evaluate for inducible ischemia and assess cardiac function. The study is ordered as a contrast-enhanced exam because baseline transthoracic images are technically limited by body habitus. The patient undergoes treadmill exercise according to a standard Bruce protocol while continuous electrocardiographic monitoring is performed. Real-time 2D imaging with m-mode recordings is obtained at rest and immediately post-exercise; a contrast agent is administered during the rest study and repeated as needed during stress to improve endocardial border definition. A supervising physician interprets the study and documents a formal report that includes wall motion analysis, ejection fraction estimation, and any inducible wall motion abnormalities. The workflow includes pre-procedure consent and IV placement for contrast, baseline vital signs and ECG, acquisition of resting contrast-enhanced images, stress exercise with continuous ECG monitoring, immediate post-stress imaging with contrast as indicated, image archiving (technical component), and physician interpretation and reporting (professional component). Typical sites of service are the hospital outpatient department, ambulatory imaging center, or cardiac catheterization lab support areas where monitored exercise testing and physician supervision are available.
