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 $3,631.

Cash price vs list price

Median list price (chargemaster)$5,030
Median cash price$3,631
Cash as a share of list, median hospital60%

At the typical hospital, asking for the cash price cuts the list price by about 40%. 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

270 hospitals filed a usable inpatient cash price for this code. The median is $3,521 and the average of the middle 60% is $2,765; most fall between $462 and $5,472.

Cash price percentiles, inpatient, across 270 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.

$246$538$3,521$4,711$7,940

The most expensive tenth of hospitals charges at least 32× what the cheapest tenth charges ($246 vs $7,940).

Of the 299 hospitals that filed this code inpatient, 270 gave a usable cash price; 22 carried a plausibility flag, 0 filed a number their own filing marks as not a price, 0 gave an estimate, and 7 a list price only.

How complete is this

389 of the 3,956 hospitals with a price file in our corpus (10%) filed a usable outpatient cash price for this code, and those are the hospitals every figure on this page is computed from.

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.
