CPT code 93350: Stress echo, echo service only2026 Medicare rate & RVUs

Medicare pays $185.37 for 93350 nationally in the office. Local office rates run $165.12–$249.45.

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

What 93350 covers

A stress echocardiogram records transthoracic images at rest and during cardiovascular stress, then compares cardiac function and wall motion across the two conditions. Cardiologists commonly use it to evaluate suspected or known coronary artery disease, including when a patient exercises on a treadmill or bicycle or receives pharmacologic stress. A sonographer may acquire the images under physician direction; the interpreting clinician reviews the study and prepares the report.

Report 93350 for the stress echocardiography service, not as a substitute for the separately performed ECG stress-test service. The record should identify the indication and stress method and support acquisition and interpretation of the rest and stress images. CMS permits separate professional (26) and technical (TC) billing; billing without either modifier represents the global service. When multiple cardiovascular diagnostic procedures are reported, the multiple-procedure reduction applies to the technical component.
