CPT code 93306: Echocardiogram (TTE), complete, with spectral and color Doppler2026 Medicare rate & RVUs

Medicare pays $196.73 for 93306 nationally in the office. Local office rates run $174.76–$265.52.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93306 covers

A sonographer obtains chest-wall images of the cardiac chambers, valves, pericardium, and proximal great vessels, using spectral Doppler and color flow mapping to assess blood flow and valve function. A cardiologist or other qualified physician interprets the images and reports findings such as chamber size, wall motion, ejection fraction, and valve function. Common reasons for the study include heart failure, a new murmur, atrial fibrillation, suspected valve disease, or syncope with suspected structural heart disease. The examination may take place in a cardiology office, hospital echo lab, or at the bedside.

Report 93306 once for a complete study with spectral and color Doppler; do not add separate codes for those Doppler services. Documentation should support a complete examination, identify structures that could not be adequately visualized, and include an interpretation. Modifier TC identifies the equipment and staff portion, while modifier 26 identifies the physician interpretation; billing without either modifier represents the global service. In a hospital, the interpreting physician typically bills with modifier 26. CMS applies a cardiovascular diagnostic multiple-procedure reduction to the technical component when eligible tests are furnished to the same patient on the same date.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
