Billing code 93351: Stress echocardiogramMedicare rate & RVUs

Medicare pays $233.47 for 93351 nationally in the office. Local office rates run $207.46–$314.68.

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

What 93351 covers

A stress echocardiogram captures cardiac ultrasound images at rest and during treadmill or bicycle exercise, or after pharmacologic stress, so the interpreting physician can assess how cardiac function changes under stress. A sonographer commonly acquires the images in a cardiology office, hospital, or outpatient imaging department; the physician supervises the stress portion and interprets the study. Continuous ECG monitoring is part of this service.

Report one unit for the complete study, supported by documentation of the stress method, image acquisition, ECG monitoring, supervision, and interpretation. The code includes the resting and stress imaging; do not separately report a resting echocardiogram or a stress ECG service for those same components. Billing without a component modifier represents the global service. Modifier 26 identifies the interpretation, while modifier TC identifies the equipment and staff. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to this code’s technical component.
