Why do prices for this code differ between hospitals?

Each hospital sets its own prices and negotiates separately with each insurer, so the disclosed price for the same code can vary widely from one hospital to another — and even between plans at a single hospital. Comparing the published figures is what this page is for; a difference does not by itself mean one hospital is better or worse.

What this page is not

It is not a quote, a guarantee, or medical advice. It shows what hospitals have published for this code, so you can compare and ask informed questions — your actual cost depends on your insurance, the exact services performed, and the care setting.
