Median: half of hospitals filed less, half more — and it is a price some hospital actually filed. Average of the middle 60%: the mean of the prices between the 20th and 80th percentiles. We never publish the plain average, the lowest or the highest price: the extremes in hospital price files are chargemaster artefacts, not prices anyone pays.

The same distribution cut by the kind of hospital. Hospital type and ownership come from CMS; a hospital counts as part of a system when its price file is shared with at least one other hospital under the same brand. The national median is $304.

Cash price vs list price

Median list price (chargemaster)$482
Median cash price$304
Cash as a share of list, median hospital65%

At the typical hospital, asking for the cash price cuts the list price by about 35%. The share is the median of each hospital’s own cash ÷ list ratio, over hospitals that filed both — not the ratio of the two medians above.

The same procedure, inpatient

1,784 hospitals filed a usable inpatient cash price for this code. The median is $300 and the average of the middle 60% is $314; most fall between $146 and $558.

Cash price percentiles, inpatient, across 1,784 hospitals. Each figure is a price a hospital filed. 10th: one in ten hospitals charges less; 25th: a quarter charge less; Median: half charge less; 75th: three quarters charge less; 90th: nine in ten charge less.

The most expensive tenth of hospitals charges at least 8.2× what the cheapest tenth charges ($99 vs $807).

Of the 1,963 hospitals that filed this code inpatient, 1,784 gave a usable cash price; 100 carried a plausibility flag, 0 filed a number their own filing marks as not a price, 0 gave an estimate, and 79 a list price only.

How complete is this

2,520 of the 3,956 hospitals with a price file in our corpus (64%) filed a usable outpatient cash price for this code, and those are the hospitals every figure on this page is computed from.

  • Since our last snapshot: there is no earlier snapshot at least 90 days older than this one yet.

We last checked these hospitals’ price files for changes between September 4, 2026 and September 25, 2026; the figures were computed September 25, 2026 from filings loaded through September 25, 2026. The percentiles and averages use only the “counted” row.

Method

Source
The machine-readable price files every U.S. hospital is required by CMS to publish, parsed per hospital. Nothing is surveyed, sampled or modelled.
What counts
One cash (self-pay) price per hospital for this code and setting. A hospital’s own filing can rule its number out — a placeholder, a “not applicable” note, a list price standing in for cash — and our plausibility checks can flag a price far below what every other hospital files. Both kinds are disclosed above and excluded from the statistics; on the compare tool a flagged price is still shown.
Statistics
Percentiles are discrete: each is a price some hospital filed. The average is the mean of the prices between the 20th and 80th percentiles. We never publish the plain mean, the minimum or the maximum. A state needs 10 hospitals and a segment 20 to show a figure; otherwise the row shows its count and no number. Medicare is the national unadjusted OPPS rate where one exists.
Names
Procedure names on these pages are our own plain-language titles, not the AMA’s copyrighted CPT descriptors. The code is the identity.

The full rules — sources, statistics, thresholds, limitations — are on the methodology page.
