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 (8) report very high prices above $6,358, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

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.
