The listed chargemaster rate is $37,558, while Medicare reimburses $4,207 for the same procedure — a ratio of 8.9x (Source: CMS IPPS Provider Summary, FY2024).

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.

MERCY HOSPITAL ST LOUIS 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.
