Same procedure, different price: what US hospitals charge cash-paying patients

For the same outpatient procedure, a patient paying without insurance can be charged many times more at one hospital than at another. Take MRI of knee or other lower-limb joint, no contrast dye (code 73721): the cheapest tenth of 1,310 hospitals list $462 or less, the most expensive tenth $3,636 or more — 7.9 times as much. Across the 11 common procedures below, that gap ranges from 6.1× to 15.1×.

Every number is computed from the hospitals' own machine-readable price files (45 CFR 180.50), collected by SelfPayRates. Data as of Sep 24, 2026. Free to cite with a link to this page.

The gap, procedure by procedure

Each hospital counts once, at its lowest outpatient cash price for the code. P10 and P90: a tenth of hospitals charge less / more.

MRI of knee or other lower-limb joint, no contrast dye: median by state

Median of each hospital's lowest outpatient cash price, states with at least 10 hospitals whose prices come from at least 5 separate websites — so one hospital system cannot set a state's number. Lowest first. The typical price in South Carolina ($2,447) is 7.6× the typical price in New Jersey ($323).

MRI of knee or other lower-limb joint, no contrast dye: shopping around in the same metro

The largest metro areas in the data. “Saves” is the typical local price minus the lowest. In 9 of these 15 metros the lowest price is half the local median or less.

Method

  • Source. Since 2021 every US hospital must publish its standard charges, including the discounted cash price, in a machine-readable file (45 CFR 180.50). We read those files directly and keep every price exactly as published, with a link to its file.
  • One price per hospital. A hospital often lists several lines for one code. Each hospital counts once, at its lowest outpatient cash price for the code, so a hospital with many lines does not outweigh one with a single line.
  • Comparable prices only. Outpatient prices only; prices for both sides of the body, physician-only or technical-only components, and lines below $1 or below a tenth of the national median for the code (almost always a separate fee or a placeholder) are left out.
  • Percentiles, not extremes. The spread is the 90th percentile divided by the 10th. Hospital files contain occasional errors, and a single wrong line should not decide a headline, so we do not report the single lowest or highest price nationally.
  • States. A hospital system usually publishes the same price for all its hospitals from one website. A state is compared only when its prices come from at least 5 separate websites; the by-state CSV has every state.
  • What is not covered. Hospitals only — not freestanding imaging centers or labs, which are often cheaper. A cash price is a published charge, not a quote: a separate physician fee may apply.
