CPT code 93307: Transthoracic echo, complete, without Doppler2026 Medicare rate & RVUs

Medicare pays $137.95 for 93307 nationally in the office. Local office rates run $122.16–$187.42.

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

What 93307 covers

This service uses an ultrasound transducer on the chest to create cardiac images for a comprehensive assessment of heart structure and function. A sonographer typically acquires the images in a hospital or outpatient imaging setting, and a physician, often a cardiologist, interprets them. The study includes two-dimensional imaging and M-mode recording when performed, without Doppler evaluation. Findings may address chamber size, wall motion, valves, and the pericardium.

Report 93307 for a complete study, not a focused or follow-up examination; the report should support the scope of a complete evaluation. When the complete study includes Doppler, 93306 is the relevant code instead. The service may be billed globally, or divided between the interpretation with modifier 26 and the equipment-and-staff portion with modifier TC. When multiple cardiovascular diagnostic procedures are performed, CMS applies its multiple-procedure reduction to the technical component.
