What 70486 covers
This service uses computed tomography to image the facial bones and related structures without contrast material. Common indications include evaluation of the paranasal sinuses and assessment of facial injury. A radiology technologist typically acquires the images in an imaging department or other equipped setting; a radiologist or other qualified physician interprets them and prepares a report.
Select this code when the documented examination covers the maxillofacial region and is performed without contrast. The order and report should support the clinical indication, anatomic coverage, and contrast protocol. The global service includes both image acquisition and interpretation when billed without a component modifier. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service. When multiple diagnostic imaging procedures are reported, the CMS 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.

70486 billing questions
How does this differ from 70487?
70486 describes maxillofacial CT without contrast. Use 70487 when the maxillofacial examination is performed with contrast.
When is 70488 appropriate instead?
70488 is for a maxillofacial CT performed both without and with contrast. This code is for an examination without contrast.
What do modifiers 26 and TC identify?
Modifier 26 reports the physician’s professional interpretation, and modifier TC reports the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
Does the multiple imaging reduction affect both components?
Yes. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.
What documentation supports reporting this code?
The record should support the clinical reason for imaging, the maxillofacial anatomy examined, and that the study was performed without contrast. The imaging report should document the findings and interpretation.
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.
