What 70471 covers
This service uses CT and contrast material to image arteries in both the head and neck. It is commonly ordered to assess concerns such as acute stroke, arterial narrowing, aneurysm, or suspected dissection. A radiologic technologist performs the scan, and a radiologist interprets the images. The study evaluates the cervical and intracranial arterial circulation as one combined examination.
Report 70471 for a combined head-and-neck angiographic study, rather than separate territory codes for the same examination. Documentation should support the clinical indication, the anatomic coverage, contrast administration, and the interpreting physician’s findings. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment-and-staff portion, and an unmodified claim represents the global service. When multiple diagnostic imaging services are performed, the CMS multiple procedure reduction applies to both the professional and technical components.

How to choose
- 70496Ct angiography head
- 70496 covers CTA of the head alone. Choose 70471 when the performed angiographic examination covers both head and neck.
- 70498Ct angiography neck
- 70498 covers CTA of the neck alone. Choose 70471 when the performed angiographic examination covers both neck and head.
- 70450Head CT
- 70450 is a noncontrast CT of the brain, not an angiographic study of head and neck arteries. It answers a different imaging question.
- 70491CT neck
- 70491 is a contrast-enhanced CT of neck soft tissues, while 70471 evaluates arteries in both the neck and head.
70471 billing questions
When should 70471 be used instead of 70496 or 70498?
Use 70471 when the CTA examination covers both head and neck arteries. The single-territory codes are alternatives when the performed study is limited to the head or to the neck.
Are the head and neck reported as separate CTA services?
For one combined head-and-neck CTA examination, report 70471 rather than separately reporting 70496 and 70498 for the same study.
How are the professional and technical portions billed?
Use modifier 26 for the physician’s interpretation and modifier TC for the technical portion. An unmodified claim represents the global service.
Does the multiple procedure reduction affect this code?
Yes. CMS applies the diagnostic imaging multiple procedure reduction to the professional and technical components when multiple imaging procedures are performed.
Does a noncontrast image make this a separate CT service?
Noncontrast images, when performed as part of the CTA examination, are included in 70471. A separately performed diagnostic CT should be distinguished from those CTA images in the documentation.
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.
