Advocate Aurora Health (formed in the Illinois-Wisconsin merger) and Ascension Wisconsin are the dominant systems in the Milwaukee market, while UW Health anchors the Madison market. Wisconsin's hospital market is moderately competitive in major metros but increasingly concentrated in rural areas. Prices tend to run near or slightly below the Midwest median. 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 $640, including Aurora BayCare Medical Center at $1,183, 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 $366 versus $281 inpatient, 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.
On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$366 |
| Deductible met - 20% coinsurance | ~$73 |
| Out-of-network provider | $805+ |
