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. Colonoscopy pricing is particularly sensitive to screening vs. diagnostic coding. A screening colonoscopy is typically covered at 100% under preventive care benefits, but if a polyp is removed or a finding is documented during the same visit, the claim is often re-coded as diagnostic - triggering your deductible and coinsurance. Ambulatory surgery centers perform over 70% of colonoscopies nationally and charge substantially less than hospital outpatient settings.

Why prices vary - and what it means for your coverage
A small number of hospitals (1) report prices above $308, including Hopedale Medical Complex at $338, 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 $206 versus $338 inpatient (about 1.6× more), so where a procedure happens often matters more than which hospital you pick. The biggest swing for this procedure is screening versus diagnostic coding - a polyp removed during a routine screening can recode the whole visit as diagnostic and trigger cost-sharing you weren't expecting.
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 | ~$206 |
| Deductible met - 20% coinsurance | ~$41 |
| Out-of-network provider | $453+ |
