What Drives Pricing Here

Regional Price Parity

Illinois's cost-of-living index sits at 101.2 — near the national benchmark (100). This directly scales facility and staffing overhead, which flow through to every procedure price.

Specialist Availability

State Context

CT Scan in Illinois: What to Know

In Illinois, self-pay patients can find a head CT scan for an average cash price significantly lower than many other states. For example, Radiology Assist offers CT scans in Chicago starting from a very competitive price. When comparing options, remember that hospital outpatient departments typically charge considerably more than freestanding imaging centers for the same CT scan.

To save on your CT scan, explore freestanding imaging centers rather than large academic medical centers, as prices can vary widely. Illinois’ Hospital Price Transparency Act, effective January 1, 2024, requires facilities to disclose detailed charges, including discounted cash prices, making it easier to compare. Verify current pricing directly with providers.
