Why prices vary this much

Setting drives much of the gap in Washington, DC: the median outpatient price is $4,280 versus $4,573 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the Washington, DC facilities reporting prices, 6 fall in a low-cost tier (up to $2,422) while 6 sit in a high-cost tier ($10,566 and up) — a lower-priced option almost always exists within the same state.

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.
