Why prices vary this much

Setting drives much of the gap in Chicago, IL: the median outpatient price is $160 versus $550 inpatient — about 3.4× more, so where a procedure is performed often matters more than which hospital you choose. Of the Chicago, IL facilities reporting prices, 14 fall in a low-cost tier (up to $100) while 13 sit in a high-cost tier ($372 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 $280 across 13 facilities, while facilities in Elgin tend to report lower prices (median: $156). 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.
