What the St. Louis numbers show
The widest gap in St. Louis: the same CMP costs 22.1× as much at one hospital as at another
MERCY HOSPITAL SOUTH reports $8 for a CMP; CHRISTIAN HOSPITAL NORTHEAST-NORTHWEST reports $174 for the same billing codes, in the same metro.
St. Louis prices run about 14% below the national middle
Comparing each of 33 procedures against the middle price across every other metro on this site, St. Louis's typical negotiated rate is lower on 25 of them. The median ratio is 0.86× the national middle.
Stress Test is St. Louis's biggest premium; C-Section its biggest bargain
Against the rest of the country, a Stress Test here runs 98% above the $329 national middle at $652, while a C-Section runs 94% below its $11,816 at $686.
Who runs the 7 St. Louis-area hospitals behind these prices
6 non-profit, with 1 not in CMS's general-information register. The largest is MERCY HOSPITAL ST LOUIS at 859 beds. Ownership matters to a price file: for-profit chains and non-profit systems publish self-pay cash prices at very different rates.
33 of 33 St. Louis procedures have a published self-pay cash price
The best-priced of them is a CBC at $18. Hospitals are not required to offer a cash price and most publish one only for outpatient imaging and lab work.
The St. Louis files behind this page span December 2025 to June 2026
Hospitals republish their Standard Charges file roughly once a year and each carries its own date, so these figures were not all filed at the same moment. Every hospital's own publication date is in its entry below.
How the negotiated, cash and chargemaster figures differ — and where each comes from — is
explained on the methodology page.
