Radiology

About 70546: Head MR angiography without and with contrast

MR angiography of the head with image acquisition before and after contrast is reported to evaluate intracranial vessels, including suspected aneurysm or stenosis.

This study uses magnetic resonance angiography to depict blood vessels within the head, with image acquisition both before and after contrast administration. It may be ordered to assess suspected intracranial aneurysm, narrowing or blockage, or a vascular malformation. A technologist performs the imaging in a hospital or outpatient imaging center, and a radiologist interprets the resulting images and provides a report. The study focuses on intracranial vessels, not the brain tissue examination reported for a standard brain MRI.

Select this code when the documented head angiography protocol includes both noncontrast and contrast-enhanced imaging; do not report it merely because contrast was planned if the performed study does not include both phases. The report and imaging record should support the head as the anatomic region and the two-part contrast protocol. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. The diagnostic imaging multiple procedure reduction applies to both the technical and professional components.

70546 billing questions

When should this code be chosen over 70544 or 70545?

Use 70546 when the head MR angiography includes both noncontrast and contrast-enhanced imaging. 70544 describes the noncontrast protocol, while 70545 describes the contrast protocol.

Can the noncontrast and contrast phases be reported separately?

Report the combined study once with 70546 when both phases are performed as the head MR angiography exam. Do not bill a separate code for each phase of that exam.

How should the professional and technical services be billed?

Use modifier 26 for the radiologist's interpretation and report, or modifier TC for the equipment and staff service. Billing without either modifier represents the global service.

Does the multiple procedure reduction affect both components?

Yes. CMS applies the diagnostic imaging multiple procedure reduction to both the professional and technical components.

What documentation supports reporting 70546?

The imaging record and radiology report should identify intracranial vessels as the target and support acquisition both without and with contrast.
