What 78481 covers

A radiopharmaceutical bolus is followed as it moves through the heart, with rapid image acquisition during its first passage through the cardiac chambers. The resulting study supports quantitative assessment of cardiac function, including wall motion and ejection fraction. Nuclear medicine physicians, radiologists, or cardiologists may perform and interpret the examination in an imaging department or hospital setting, with or without pharmacologic intervention.

Report 78481 for a single first-pass study, rather than a series of first-pass studies. Documentation should identify the study performed and include the image interpretation and quantitative findings. The service has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. When multiple cardiovascular diagnostic procedures are performed, CMS applies the 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.

78481 billing questions

When is 78481 used instead of 78483?

Use 78481 for a single first-pass cardiac function study. Use 78483 when multiple first-pass studies are performed.

Can the interpretation and imaging be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.

What happens when other cardiovascular diagnostic procedures are performed?

CMS applies its cardiovascular diagnostic multiple-procedure reduction to the technical component. The reduction does not apply to the professional component.

How does 78481 differ from a gated blood-pool study?

78481 follows the tracer during its first passage through the heart. Gated blood-pool imaging, such as 78472, uses a different acquisition approach.

What should the report document?

Document that a single first-pass study was performed, the interpretation, and quantitative findings such as wall motion and ejection fraction.

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.
