What 70470 covers

This examination acquires CT images of the head or brain before and after intravenous contrast. Radiologists interpret the images, while CT technologists perform the scan under the ordering clinician’s direction. Common clinical situations include evaluation of a suspected intracranial mass or infection when both unenhanced and contrast-enhanced images are requested. The service is performed in hospital imaging departments and outpatient diagnostic imaging centers.

Report this code when the study includes both the noncontrast and contrast-enhanced phases; use a single code for the complete examination rather than separate codes for each phase. The order and imaging report should support the head or brain anatomy examined and the acquisition of both phases. The service may be billed globally, or the interpretation and the equipment-and-staff portion may be billed separately with modifiers 26 and TC. When multiple diagnostic imaging procedures are performed, Medicare’s multiple-procedure reduction applies to both the technical and professional components.

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.

70470 billing questions

When should this code be chosen instead of 70450 or 70460?

Use this code when the head CT includes both noncontrast and contrast-enhanced image acquisitions. Code 70450 describes a noncontrast study, while 70460 describes a study with contrast only.

Should the two phases be reported as separate CT services?

No. Report one unit of this code for the complete head CT with both phases, rather than separate codes for the precontrast and postcontrast acquisitions.

How are the interpretation and scan acquisition billed?

The global service is billed without a component modifier. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion, including equipment and staff.

Can a professional or technical component be subject to a multiple-procedure reduction?

Yes. When multiple diagnostic imaging procedures are performed, the Medicare multiple-procedure reduction applies to both the professional and technical components.

What documentation supports reporting both contrast phases?

The order and imaging report should identify the head or brain study and show that images were acquired both before and after contrast. A contrast-enhanced phase alone does not support this code.

Is this the appropriate code for a head CTA?

No. This code describes a routine head CT with and without contrast; code 70496 is for head CT angiography when vascular imaging is performed.

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.
