HCPCS 70470

Computed tomography, head or brain; without contrast material, followed by contrast material(s) and further sections

AI EXPLANATION: A brain CT scan is a specialized diagnostic imaging test that uses a rotating X-ray machine and computer processing to create detailed, cross-sectional views of the head and brain tissue. During this two-part scan, initial images are taken of the brain without any contrast dye. Next, a contrast material is administered, typically through an IV, to highlight blood vessels, fluid pathways, and soft tissues before a second set of images is captured.
