Maryland: exempt

Not subject

Maryland’s hospitals are exempt from this program’s cut.

For fiscal year 2026, CMS reports a Total HAC Score of −0.5056 for MedStar Union Memorial Hospital and a payment reduction decision of N/A.

Maryland’s hospitals are scored but not subject to the reduction. 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 20% of the other 2,928 scores CMS published (higher is worse).

CMS’s note on the payment reduction: Maryland hospitals are waived from receiving payment adjustments under the Program.

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 CDI down to the national median (0.346) would lower the score the most: by 0.0279, to −0.5335. Try it in the what-if

Figure 1. Of its 5 measures with a value, this hospital is above the national median on 2; CDI added the most to its score.

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.

Added from the rounded z‑scores CMS published, the parts make −0.5056; CMS reports −0.5056. The small difference is rounding.

CMS reports a Total HAC Score of −0.5056 and a payment reduction decision of N/A (not subject to the reduction).

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.

Each measure weighs 1 ÷ 5 of the score.

Interactive what-if at https://paidandpenalized.org/hacrp/hospital/210024/

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.

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.

Figure 4. 4 of its 4 infection measures ended lower than they started.
