Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 70450 covers

This study images the skull, brain, and intracranial spaces with CT and no contrast material. A radiologic technologist acquires images, typically viewed in brain and bone windows, and a radiologist interprets them. Often performed in emergency departments, it helps evaluate suspected stroke before thrombolysis, head injury after a fall, sudden severe headache, altered mental status, seizures, or known intracranial bleeding.

Select 70450 when only noncontrast head images are obtained. Use 70460 for contrast-enhanced images only, or 70470 when head images are obtained both before and after contrast in the same session. The report should document the indication, technique, and findings, such as hemorrhage, mass effect, midline shift, or fracture. Modifier 26 identifies the radiologist's interpretation; modifier TC identifies the scanner, staff, and other technical work. Billing without either modifier represents the global service. CMS applies the diagnostic imaging multiple procedure reduction to eligible technical and professional components when multiple imaging studies are furnished, such as head and cervical spine CT after trauma.

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.
