How to read this comparison.

The cash-pay price is what an uninsured patient would be charged at each hospital. It's the cleanest apples-to-apples comparison because it doesn't depend on your insurance plan.

The CMS rating is the federal quality composite, built from ~50 measures spanning safety, mortality, readmission, patient experience, and timeliness. A 5-star hospital may not be the best at every procedure, and a 3-star hospital can have a strong specific service line. Treat the rating as one input, not the answer.

For your specific insurance plan, prices can shift dramatically. Some hospitals negotiate steep discounts with one insurer and not another. Always check the plan-specific rate before you book.
