CPT code 93306: Echocardiography, complete with Doppler and color flow

CPT code 93306 is used for a complete transthoracic echocardiogram with spectral and color flow Doppler. This non-invasive imaging test assesses heart structure and function, helping to evaluate conditions like valvular disease, cardiomyopathy, or heart failure.

CPT 93306 can typically be billed once per encounter or as medically necessary based on clinical documentation. If multiple studies are performed, documentation must clearly support the need for repeat testing, and payers may impose frequency limitations to avoid overuse.

The CPT code for a complete echocardiogram is 93306. It includes 2D imaging, M-mode, and Doppler (both spectral and color flow), providing a comprehensive evaluation of the heart.
