Quick take
- Mercy Medical Center is the lowest-cost option at $111 - $695 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $806, and it's often lower than what insurance pays before your deductible is satisfied.
- Freestanding ambulatory surgical centers (ASCs) are often 30-60% cheaper than hospital outpatient departments for the same procedure and may not appear in this hospital-only dataset - ask your doctor if one is an option.
Illinois presents two distinct markets: Chicago (highly competitive, high commercial rates, major academic medical centers) and downstate (lower density, smaller regional systems, lower rates). Northwestern Medicine, Advocate Aurora Health, and Rush University Medical Center compete aggressively in the Chicago market. Downstate Illinois prices typically run 20–35% below Chicago-area rates for identical services. Head CT pricing follows the site-of-service pattern of other imaging, but emergency use dominates - most head CTs are ordered in emergency rooms, where facility fees can add $1,000–$3,000 on top of the imaging charge. Planned outpatient head CTs for follow-up or surveillance at independent imaging centers cost a fraction of the ER equivalent. If your order is non-urgent, ask your doctor for an outpatient referral to a freestanding imaging center.

Why prices vary - and what it means for your coverage
A small number of hospitals (2) report prices above $4,090, including Regency Hospital of Northwest Indiana at $4,441, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $800 versus $1,930 inpatient (about 2.4× more), so where a procedure happens often matters more than which hospital you pick. Whether the scan happens in a hospital outpatient department (which adds a separate facility fee) or a freestanding imaging center is usually the single biggest driver of price for this procedure.
None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$806 |
| Deductible met - 20% coinsurance | ~$161 |
| Out-of-network provider | $1,773+ |

What matters before you schedule
ASC vs. hospital
Hospital outpatient departments typically charge 2-4x more than ASCs or independent centers for the same ct scan (head) - same outcome, very different bill. The ER charges the most of any setting and should only be used when the situation is medically urgent. Call ahead and ask for a self-pay or cash quote at each setting you're considering.
With vs. without contrast
Which type your doctor orders for this ct scan (head) changes the billing code, and what you pay. For example: A standard ct scan (head) with no contrast dye - the most common and lowest-cost version.
This is shoppable
CT Scan (Head) is elective and schedulable, so you have time to compare facilities before booking - hospital outpatient prices often run 2-4x higher than alternative settings for the identical clinical outcome.
What to ask before you book
Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for ct scan (head) before you schedule.
