This hospital publishes its prices in a machine-readable file, as federal law requires. Below are the consumer procedures we track from that file. Prices come from the file dated March 31, 2026. See the hospital's own source file.
Every price on this site comes from a file the hospital itself must publish under the federal Hospital Price Transparency rule. Each procedure has up to three prices, and they mean very different things.
The discounted cash price is what the hospital publishes for a person paying out of pocket, without insurance. For most people comparing hospitals, this is the most useful number, so we put it first and biggest.
The gross or "list" charge is the hospital's sticker price before any discount. Almost nobody pays it, but it is the starting number discounts are taken from, so we show it, labeled.
Hospitals negotiate a different rate with every insurance plan. We show the lowest and highest negotiated rates the hospital published. The low end can be a government program fee schedule (such as Medicaid), and the high end can be a contract formula rather than a real paid amount. Your plan's rate is somewhere inside the range. Treat the range as context, never as a promise.
Pages also show a Medicare rate: Medicare's national payment rate for the same procedure, from the fee schedules the Centers for Medicare & Medicaid Services (CMS) publishes for 2026. It is a benchmark to compare against — not a price anyone can ask a hospital for. It is also a total rate: for most services Medicare pays about 80% of it, and the remaining 20% falls to the patient or their supplemental coverage; lab tests are paid at 100%. What Medicare pays a specific hospital is adjusted for local wages, so the national figure is approximate by design.
Every price page shows the date of the hospital's file and links to that file, so you can check the number yourself. Hospitals republish their files over time; when they do, we reload and the date here changes.
Published prices are not a quote and not a guarantee of your final bill. Your bill can include other charges (for example, separate professional fees) and depends on your coverage. This site publishes price data only and gives no medical advice.
