How to use these prices

A cash price is what the hospital says it charges patients who pay for themselves. An insured average is what insurance plans pay on average, which is a useful guide when a hospital doesn’t list a cash price. Ask the hospital for its self-pay price before you book, and for a written Good Faith Estimate.

For your doctor’s office: these prices are for billing code CPT 45378.

These are estimates from prices hospitals publish under federal price transparency rules, from files dated Feb 2026. They are not a quote or a bill, and the hospital may charge a different amount. “Lowest” means the lowest published price we found, not a guaranteed price.

If you are uninsured or paying cash, you have the right to a written Good Faith Estimate from the provider before you schedule care, and you can dispute a bill that comes in $400 or more above it.

Your provider may bill a different code for the same visit. CPT is a registered trademark of the American Medical Association. More about these prices
