from this program

For fiscal year 2026, CMS reports a Total HAC Score of 0.1774 for San Dimas Community Hospital and a payment reduction decision of No.

A cut would have taken about $138K estimate 1% of about $13.8M, this site’s estimate of what traditional Medicare pays it for inpatient stays in a year. Its score was 0.2025 under 0.3799, the lowest score CMS cut.

Likely range $105–173K

Its score was at or below CMS’s line, so this program did not cut its Medicare payments 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 63% 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 MRSA down to the national median (0.641) would lower the score the most: by 0.4100, to −0.2326. 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.

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; 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.

Figure 3. The cut is a cliff, not a slope: this hospital’s score, 0.2025 under the lowest score CMS cut, costs it nothing; 0.2025 higher, the cut would have been about $138K by this site’s estimate, the same as at CMS’s highest score, 2.3133.

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, 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.

Figure 4. No HAC cut this year; 1% of the hospital’s whole inpatient payment would have been about $138K by this site’s estimate. The readmissions and value-based adjustments, on the base alone, came to −$233K and −$71K.

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 0.1774 and a payment reduction decision of No.

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.

How much cushion?

Staying at or under CMS’s line keeps about $138K out of this program’s cut, this site estimates: a score a hair over would cost all of it.

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.

Its infections, year by year

This hospital’s infection rate against prediction for each calendar year Care Compare published one, on each measure with at least two years of results (black), over the nation’s middle hospital (gray). Below the dashed line at one, fewer infections than predicted. Each year is measured against the same fixed baseline, not against other hospitals, so unlike the score they can all improve at once.
