What 70490 covers
This study uses computed tomography to produce cross-sectional images of the neck’s soft tissues without contrast material. Radiologists interpret examinations performed in hospital imaging departments, outpatient centers, and other diagnostic imaging settings. Clinical questions may involve a neck mass, cervical lymph nodes, or other soft-tissue findings; the ordering clinician selects the protocol based on the diagnostic question and the patient’s circumstances.
Report 70490 when the examination covers the soft tissues of the neck and is performed without contrast. The order and imaging report should support the anatomic area examined and the noncontrast technique. Use 70491 for a neck soft-tissue CT with contrast, or 70492 when both without- and with-contrast imaging is performed. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC the equipment and staff, and no modifier represents the global service. When multiple diagnostic imaging procedures are reported, the imaging multiple-procedure reduction applies to both the professional and technical 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.

70490 billing questions
When should 70490 be chosen over 70491?
Use 70490 for a neck soft-tissue CT performed without contrast. Use 70491 when contrast is administered for the examination.
How does 70490 differ from 70492?
70492 represents a neck soft-tissue CT performed both without and with contrast. 70490 represents the noncontrast examination only.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Billing without a modifier represents the global service.
What documentation supports reporting 70490?
The order and imaging report should identify the neck soft tissues as the imaged area and support that the examination was performed without contrast.
How does the multiple-procedure reduction affect this code?
When multiple diagnostic imaging procedures are reported, the CMS imaging multiple-procedure reduction applies to the professional and technical components of 70490.
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.
