2. The patient lies still on the examination table while X-rays are focused on the head or brain.
3. The X-ray tube and X-ray detectors rotate around the patient, producing cross-sectional images of the head or brain.
4. A computer generates these images, allowing healthcare professionals to study and evaluate the structures of the head or brain.

4. Qualifying circumstances

CPT 70450 is used when a CT scan of the head or brain is performed without the use of contrast material. It is typically indicated for patients who require diagnostic imaging to evaluate potential abnormalities or conditions affecting the head or brain. The absence of contrast material means that the scan does not involve the administration of any special dyes or substances to enhance the visibility of internal structures.

5. When to use CPT code 70450
