When you receive a bill from ASCENSION SAINT THOMAS HOSPITAL, you are typically seeing the hospital's “chargemaster” rate — its published list price for each service.

What does this actually mean for your bill? Chargemaster rates are rarely what patients pay. If you have insurance, your insurer has negotiated a separate rate — often 40–60% less than the listed price. If you are uninsured, you may be able to negotiate directly with the hospital or request financial assistance. The chargemaster-to-Medicare ratio is a useful reference point for understanding listed pricing, but it does not represent what most patients will owe out of pocket.

ASCENSION SAINT THOMAS HOSPITAL is a voluntary non-profit - private acute care hospitals facility with a CMS quality rating of 3/5 stars. Note: CMS quality ratings measure patient outcomes and experience, not pricing. A hospital with high listed prices may provide excellent care, and pricing data alone should not be used to evaluate the quality of a healthcare provider.
