CT imaging
About 70491: Contrast-enhanced soft tissue neck CT
Contrast-enhanced CT of the soft tissues of the neck, reported to evaluate masses, adenopathy, infection, or other nonvascular neck abnormalities.
This study uses computed tomography with contrast to depict soft tissues of the neck, including structures such as the pharynx, larynx, thyroid region, and cervical lymph nodes. It is commonly ordered to assess a neck mass, enlarged nodes, or suspected deep neck infection. A technologist acquires the images, and a radiologist or other qualified physician interprets them in a hospital, imaging center, or office setting.
Select this code when the documented examination covers the soft tissues of the neck and uses contrast; use a different code for a noncontrast study or one performed both without and with contrast. The order, imaging record, and interpretation should support the examined region, contrast protocol, and clinical question. The service may be billed globally, or the professional interpretation with modifier 26 and the technical service with modifier TC. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.

70491 billing questions
How does this differ from 70490?
70491 is for a soft tissue neck CT performed with contrast. 70490 describes the corresponding study without contrast.
When should 70492 be used instead?
Use 70492 when the neck CT is performed both without and with contrast. A study performed with contrast only is reported with 70491.
Can the interpretation and image acquisition be billed separately?
Yes. Report the professional interpretation with modifier 26 and the technical service with modifier TC; billing without either modifier represents the global service.
Does the multiple procedure reduction affect this code?
CMS applies the diagnostic imaging multiple procedure reduction to the technical and professional components. This can affect either component when it is billed separately.
How does this differ from a neck CT angiography?
70491 evaluates neck soft tissues with contrast. 70498 is for CT angiography of the neck when the examination is directed at blood vessels.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
