What 70492 covers
This examination uses computed tomography to assess soft tissues in the neck, including structures such as cervical lymph nodes, salivary glands, and the pharynx or larynx. It may be ordered to evaluate a neck mass, enlarged nodes, or suspected deep neck infection. A radiologic technologist acquires the images, typically with intravenous contrast for the enhanced portion, and a radiologist interprets the study in an outpatient imaging center or hospital department.
Report this code when the examination includes images obtained both without and with contrast; a contrast-only study is coded differently. The order and report should support the clinical indication, the neck anatomy examined, both image sets, and the interpreting physician’s findings. Billing without a component modifier represents the global service. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service. When multiple diagnostic imaging procedures are performed, the multiple procedure reduction applies to both the technical and professional components.

70492 billing questions
When should this code be selected instead of a contrast-only neck CT?
Use this code when the neck CT includes image acquisition both before and after contrast. A study performed only with contrast is reported with 70491.
Can the interpretation and imaging service 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.
How does the multiple imaging reduction affect component billing?
When multiple diagnostic imaging procedures are performed, the reduction applies to both the professional and technical components.
Should the precontrast and postcontrast image sets be reported as separate units?
No. The code represents the neck CT examination with both image sets, rather than a separate service for each set.
What documentation supports reporting this code?
The record should support the clinical reason for the neck examination and show that images were obtained both without and with contrast, along with the interpreting physician’s findings.
