What 70548 covers

This service is an MRI-based angiographic study of the arteries in the neck performed after contrast administration. It is commonly used to evaluate carotid and vertebral artery disease, including suspected stenosis, dissection, or aneurysm. A radiology technologist performs the acquisition, and a radiologist interprets the images and prepares the report. It may be performed in a hospital imaging department or an outpatient imaging center.

Choose this code when the documented study is MR angiography of the neck performed with contrast, rather than a soft-tissue neck MRI or a neck MRA performed without contrast. The order, imaging record, and interpretation should support the neck arterial anatomy examined and contrast use. Medicare recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the 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 when applicable.

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.

Use 70549 when the neck MRA includes both noncontrast and contrast imaging. 70548 represents the contrast-enhanced study.
70545Head MR angiographyWith contrast
70545 is MR angiography of the head with contrast. Choose 70548 for the neck arterial territory.
70542MRI with contrastOrbit, face, or neck

70548 billing questions

How does 70548 differ from 70547?

70548 is for neck MR angiography performed with contrast. Use 70547 when the neck MRA is performed without contrast.

When is 70549 more appropriate?

70549 describes neck MR angiography performed both without and with contrast. Use 70548 when the study is performed with contrast, not with both phases.

Can the professional and technical services be billed separately?

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

Does the multiple imaging reduction affect both components?

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

Is this the correct code for a contrast-enhanced MRI of neck soft tissues?

No. This code is for MR angiography of the neck arteries. A neck soft-tissue MRI is a different study, even if it uses contrast.
