About a head CT

A CT scan of the head without contrast dye. It is fast and widely available, and is often used after a head injury, for a sudden severe headache, or to check for bleeding. Billing code: CPT 70450.

What the price covers

  • Rates here are for the whole service billed as one charge: the scan and the radiologist's reading.
  • Head CTs done in an emergency room are billed at the hospital's own, usually higher, rates plus the emergency visit. This page covers offices and imaging centers only.
  • A head CT with contrast (CPT 70460) is a different code.

What you would actually pay

The negotiated rate is the total the provider is paid. Your share depends on your plan. If you have not met your deductible, you usually pay the whole negotiated rate: at a $227 rate, that is $227. Once the deductible is met, coinsurance applies: at 20% coinsurance you would pay $45 and the insurer the rest. Plans with a flat copay for this service charge the copay instead.

Going out of network is different. The provider has no agreed rate with your insurer, so they can usually bill their full listed price. Federal and California law limit that in emergencies and for some out-of-network clinicians at in-network hospitals.

Paying without insurance

The rates on this page are what insurers pay in network, not cash prices. If you are paying yourself, they are still a useful benchmark: ask the provider for its self-pay price before you book and compare it with these rates and with Original Medicare's $140 for a head CT in Oakland. Many freestanding imaging centers post cash prices for scans. Hospitals must publish a discounted cash price under federal price transparency rules, and if you are uninsured or paying yourself, the No Surprises Act entitles you to a written good faith estimate before scheduled care.

Where these numbers come from
