Colonoscopy Cost in Wisconsin (2026): Average Prices & What You'll Pay

What does a colonoscopy cost in Wisconsin?

Expect roughly $959 to $2,649 for a colonoscopy in Wisconsin if you're commercially insured — that range already folds in both the facility charge and the physician fee. The median reported facility price across 115 hospitals is $926. It's built from CMS fee schedules and federally mandated hospital price transparency data.

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.

Insurers negotiate this down to a median of $634, while self-pay patients are quoted $926 — about 1.5× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill. Wisconsin prices for a colonoscopy span 292.5× across 115 reporting hospitals, from $100 (Upland Hills Health in Dodgeville) up to $29,247 (Aurora Sinai Medical Center of Aurora Health Care Metro Inc in Milwaukee) for identical care. The median Wisconsin price is $926. Most facilities fall between $396 and $1,293. Where you go inside Wisconsin counts as much as which plan you have: Sheboygan's median ($1,676) runs 2.2× Madison's ($778).

Most expensive colonoscopy providers in Wisconsin

These facilities report the highest prices for this procedure. Academic medical centers and specialty hospitals often top this list — their gross charges rarely reflect what anyone actually pays, but understanding the spread helps you negotiate.

Why prices vary this much

A small number of hospitals (13) report very high prices above $3,268, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

Setting drives much of the gap in Wisconsin: the median outpatient price is $702 versus $1,468 inpatient — about 2.1× more, so where a procedure is performed often matters more than which hospital you choose. Of the Wisconsin facilities reporting prices, 47 fall in a low-cost tier (up to $396) while 48 sit in a high-cost tier ($1,545 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Green Bay has a median reported price of $794 across 8 facilities, while facilities in Madison tend to report lower prices (median: $778). City-level variation within a state often reflects local market structure, not procedure complexity.

The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay

Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.

Frequently asked questions: colonoscopy costs in Wisconsin

How much does a colonoscopy cost in Wisconsin?

Across 115 Wisconsin hospitals that publish prices, a colonoscopy ranges from $100 to $29,247, with a median of $926. Most facilities fall between $396 and $1,293. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Where is the cheapest place to get a colonoscopy in Wisconsin?

Based on declared prices, the lowest-cost facility in our Wisconsin data is Ascension NE Wisconsin, Inc. at about $202. By metro, Madison has the lowest median ($778). 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.
