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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

93351 billing questions

How does 93351 differ from 93350?

93351 includes continuous ECG monitoring and physician supervision along with the stress echocardiography. 93350 reports the stress echo without those ECG stress-test services included.

Can a resting echocardiogram be billed separately on the same study?

The resting images are part of the complete stress echocardiogram. Do not separately report a resting echo for those images.

Should a separate cardiovascular stress test code be reported with 93351?

The ECG monitoring and physician supervision for the stress test are included in 93351. Do not report another stress-test service for those same components.

When should modifier 26 or TC be used?

Use modifier 26 for the physician’s interpretation and report, or modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

What documentation supports 93351?

Document the stress method, rest and stress image acquisition, continuous ECG monitoring, physician supervision, and the interpretation and report.

How does the multiple procedure reduction affect 93351?

When the cardiovascular diagnostic multiple procedure reduction applies, it affects the technical component of 93351.

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.
