2025 CPT code 70498
(Active) Effective Date: N/A Revision Date: N/A Diagnostic Radiology - Computed Tomographic Angiography Diagnostic Radiology (Diagnostic Imaging) Procedures of the Head and Neck Feed
Computed tomographic angiography (CTA) of the neck with contrast material, including non-contrast images if performed, and image post-processing.
Modifiers 26 (professional component), TC (technical component), and other applicable modifiers may be used as per guidelines.Consult payer specific rules for modifier usage.
Medical necessity for a CTA neck is established when clinical findings suggest the need to evaluate the neck's vasculature for conditions like stenosis, occlusion, trauma, or aneurysm.The decision to perform the procedure should be based on the patient's clinical presentation, risk factors, and other diagnostic test results.
The physician is responsible for ordering the exam, interpreting the images, and managing the patient's care based on the results. The technologist is responsible for patient positioning, IV line insertion (if needed), contrast administration, and operating the CT scanner.

- Diagnostic Radiology (Diagnostic Imaging) Procedures of the Head and Neck
In simple words: A CT scan of the neck's blood vessels is done after injecting a special dye into a vein.This helps doctors see the blood vessels clearly to check for problems like blockages or aneurysms.
This CPT code encompasses the performance of a computed tomographic angiography (CTA) of the neck.The procedure involves intravenous injection of contrast material, acquisition of CT images (including non-contrast images if obtained), and subsequent image post-processing. The procedure visualizes blood vessels in the neck to detect aneurysms, blood clots, or other vascular irregularities.
Example 1: A 60-year-old male patient presents with symptoms suggestive of carotid artery stenosis. A CTA neck is performed to visualize the carotid arteries and assess for stenosis or occlusion., A 55-year-old female patient with a history of neck trauma undergoes a CTA neck to evaluate for vascular injury., A 70-year-old patient with a suspected neck aneurysm is sent for a CTA neck to confirm the diagnosis and assess the size and location of the aneurysm.
The medical record should include the indication for the CTA neck, patient history and physical examination findings, images and reports from the CT scan, and the physician's interpretation and plan of care.
** Payers may have specific requirements regarding contrast material coverage and coding for its supply.Always check with the specific payer for their policies.
