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 (1) report very high prices above $4,568, 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 Illinois: the median outpatient price is $1,265 versus $1,510 inpatient — about 1.2× more, so where a procedure is performed often matters more than which hospital you choose. Of the Illinois facilities reporting prices, 41 fall in a low-cost tier (up to $683) while 41 sit in a high-cost tier ($2,237 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Chicago has a median reported price of $1,179 across 19 facilities, while facilities in Oak Lawn tend to report lower prices (median: $780). 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.
