The urban-rural price gap in Colorado is one of the widest in the country. CT scan pricing is driven almost entirely by site of service - the identical scan costs 3–6× more at a hospital outpatient department than at an independent imaging center. With-contrast and without-contrast scans carry different CPT codes and prices, so confirm which your physician ordered before scheduling. For non-urgent imaging, comparing cash prices across independent imaging centers near you typically yields the largest savings.

Why prices vary - and what it means for your coverage
Facility classification matters as much as the hospital itself - a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. 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 | ~$144 |
| Deductible met - 20% coinsurance | ~$29 |
| Out-of-network provider | $317+ |

What matters before you schedule
Imaging center vs. hospital
Hospital outpatient departments typically charge 2-4x more than independent imaging centers for the same ct scan - 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 changes the billing code, and what you pay. For example: A standard ct scan with no contrast dye - the most common and lowest-cost version.
This is shoppable
CT Scan 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 before you schedule.
