What 93308 covers

This service is a focused ultrasound examination of the heart through the chest, using two-dimensional imaging and M-mode when performed. A sonographer typically acquires the images in an office, hospital, or outpatient imaging department, and a qualified physician interprets the study. Common reasons include reassessing a known pericardial effusion or checking ventricular function after a prior study when only a specific question needs evaluation.

Choose this code when the documented examination is limited or performed as follow-up, rather than a complete transthoracic study. The record should support the clinical question, the focused scope of the examination, and the interpretation of the images. Doppler services, when performed and reported, use the applicable Doppler codes. The service may be billed globally, or split into the professional interpretation with modifier 26 and the equipment-and-staff technical component with modifier TC. CMS applies the cardiovascular diagnostic multiple procedure reduction to the 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.

93308 billing questions

How does 93308 differ from a complete transthoracic study?

93308 is for a focused or follow-up examination addressing a limited clinical question. Use a complete-study code when the examination covers the full scope of a complete transthoracic study.

Can Doppler services be reported with 93308?

Yes, when Doppler assessment is performed and documented, report the applicable Doppler code, such as 93321 for a limited or follow-up Doppler study. Color flow mapping may be reported with 93325 when performed.

When should modifier 26 or TC be used?

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

What documentation supports choosing 93308?

Document the reason for the focused or follow-up examination, the specific cardiac question assessed, the images and findings, and the interpreting physician's conclusion.

Which part of the service is subject to the cardiovascular multiple procedure reduction?

CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component of 93308.

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.
