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 (13) report prices above $3,268, including Select Specialty Hospital - Milwaukee (St Francis Campus) at $7,037, 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 $702 versus $1,468 inpatient (about 2.1× 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.

What you pay out of pocket on top of this depends on your deductible, your plan's out-of-pocket maximum, and whether every provider involved is in-network - not just the facility.

Freestanding ambulatory surgery and imaging centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.

Why is a colonoscopy so much cheaper at some Wisconsin hospitals?

Prices vary up to 292.5× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Wisconsin, the median cash (self-pay) price is $926 versus a median negotiated rate of $634 - about 1.5× higher. Asking for the cash price or your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a colonoscopy in Wisconsin?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.
