cut from its FY2026 Medicare inpatient payments, this site estimates estimate
For fiscal year 2026, CMS reports a Total HAC Score of 1.6627 for Louis A Weiss Memorial Hospital and a payment reduction decision of Yes.
That is 1% of about $19.3M, this site’s estimate of what traditional Medicare pays it for inpatient stays in a year plus the teaching payments Medicare makes on its Medicare Advantage patients’ stays: about $206 per traditional Medicare stay.
Likely range $147–242K
Its score was above CMS’s line, so CMS cut its Medicare inpatient payments by 1% for the year. The score compares hospitals with each other; it is not a grade of the quality of care.
CMS cut scores of 0.3799 and above.
Each year CMS cuts the hospitals with the highest quarter of scores, those above the 75th percentile, so the line moves with other hospitals’ scores.
Higher than 98% of the other 2,928 scores CMS published (higher is worse).

Where the score came from
CMS scored this hospital on 5 of the 6 measures. On every measure a lower value is better. Each row puts the hospital among every hospital with a value: the gray columns are those hospitals, the tall tick is the national median, and the hatched ends score the same as CMS’s floor or cap.
Bringing PSI 90 down to the national median (0.9623) would lower the score the most: by 0.5017, to 1.1610. Try it in the what-if

How the parts add up
CMS adds the z‑scores and divides by the number of measures scored, so each measure counts the same. Each bar below is one z‑score divided by 5; a bar right of zero raised the score and one left of zero lowered it.
(2.3255PSI 90+1.8691CLABSI−0.2990CAUTI+2.1931CDI+2.2251MRSA)÷5measures=1.6627Total HAC Score
Added from the rounded z‑scores CMS published, the parts make 1.6628; CMS reports 1.6627. The small difference is rounding.
This hospital’s score is 1.2835 above 0.3792, the highest score CMS marked No. (This site recomputes.)

The money is a cliff
This program’s cut doesn’t grow with the score. Over CMS’s line, CMS cuts 1% of what traditional Medicare pays a hospital for inpatient stays that year, and of the teaching payments Medicare makes on its Medicare Advantage stays; at or under the line, this program cuts nothing.
The chart draws what the cut would be for this hospital at any Total HAC Score, from this site’s estimate of its payments, with its own score marked.
Under the axis, every Total HAC Score CMS published: 306 of the 2,929 scored within 0.1 of CMS’s line, on one side or the other.

The money, line by line
This site estimates what traditional Medicare pays the hospital for a year of inpatient stays, and the teaching payments Medicare makes on its Medicare Advantage patients’ stays, from CMS’s FY2026 payment files, then applies Medicare’s three hospital quality programs: the readmissions and value-based adjustments to the base payment, and the HAC cut last, as the law sets.
The readmissions and value-based programs adjust only the base payment: the DRG rates times the hospital’s cases, and a Medicare-dependent hospital’s add-on. The HAC cut comes last and takes 1% of everything left, teaching, low-income-patient, outlier, capital and uncompensated care payments included.

Whole dollars, so every line adds up; the estimate is not that precise. Each likely range spans the middle 80% of the misses this site’s estimate made for similar hospitals (or for a wider group, where there were too few) when it was checked against their FY2024 cost reports: one year’s check, not a promise of how often a hospital’s actual figure lands inside.

CMS’s line: between 0.3792 and 0.3799
The faint ticks are CMS’s line in earlier years under the same formula, from about 0.300 (FY2022) to about 0.375 (FY2024). The line moves every year, so a hospital can cross it without changing anything.
CMS reports a Total HAC Score of 1.6627 and a payment reduction decision of Yes.
Estimate: a changed measure’s z‑score is this site’s recompute, which can differ slightly from CMS’s. How this site estimates
A what-if shows the formula’s arithmetic, not what a hospital could realistically change or how. CMS’s real result also depends on other hospitals.
Bring all to the national median lowers each measure above its national median to that median and leaves the measures CMS assigned as they are.
What would it take?
Getting under CMS’s line would keep about $193K, this site estimates: the whole cut, however far under the score lands.
From CMS’s values, one measure at a time, with every other measure held at CMS’s value.

Among hospitals with a Yes or No payment decision, CMS cut those with a published Total HAC Score of 0.3799 or higher and none at 0.3792 or lower. Maryland’s hospitals are scored but not subject to the reduction.
Held fixed: every other hospital’s results, CMS’s line, and each measure’s mean, spread, floor and cap as this site fits them to CMS’s published values.
Year by year
Where this hospital’s score fell among every hospital’s, each year CMS published one. A score near the top is among the highest; the shaded band is where CMS cut. Places compare across years even where CMS changed how it builds the score.
