Operating margins, losses, charity care, beds and staff for 137 Wisconsin hospitals, from the cost reports they file with Medicare, compared with the rest of the U.S.
Hospitals whose patient care cost more than it brought in, in their latest full-year report — fewer than the national share.
The median Wisconsin hospital kept 3.2% of its patient revenue after operating costs, against -1.6% nationally (#12 of 50 states). Excludes donations and investment income.
The cost of free or discounted care Wisconsin hospitals gave patients who qualified, in their latest full-year reports: 0.9% of the U.S. total of $35.6 billion.
99,622 full-time-equivalent employees across 137 hospitals with a cost report.
Charity care is reported at cost, not at list prices. The share is charity care as a part of the hospital's operating expenses.
The lowest operating margins among Wisconsin hospitals with a full-year report. A negative margin means patient care cost more than it brought in; donations, grants and investments can still cover the gap.
Latest fiscal year each hospital reported. Reports marked "partial year" cover only part of a year (for example after a change of owner) and are left out of the state totals. Click a column to sort.

Figures as reported to CMS (Hospital Provider Cost Report), not audited statements. Operating margin = net income from patient care ÷ net patient revenue; it excludes investment income, donations and grants. Charity care is the cost of free or discounted care for patients who qualify under the hospital's financial assistance policy. How to read these figures.
Median operating margin of each state's hospitals (patient care only)
Median operating margin in nearby states:
51 of 133 Wisconsin hospitals (38%) reported a loss on patient care in their latest full-year Medicare cost report, compared with 55% nationwide. The median operating margin was 3.2%, higher than the U.S. median of -1.6%. The operating margin leaves out donations, investment income and grants, so some of these hospitals still end the year in the black.
Wisconsin hospitals reported $322.5 million in charity care (the cost of free or discounted care for patients who qualify) in their latest full-year reports. The largest amounts came from University of Wi Hospitals & Clinics Authority ($40.8 million), Aurora St Lukes Medical Center ($32.3 million), Froedtert Mem Lutheran Hsptl ($26.3 million), Gundersen Luth Med Ctr ($18.9 million), Wheaton Franciscan Healthcare- All Saints ($12.2 million).
Wisconsin ranks 12 of 50 states by the median operating margin of its hospitals (1 = highest). A smaller share of its hospitals lost money on patient care than the U.S. as a whole (38% vs 55%).
University of Wi Hospitals & Clinics Authority in Madison reported the most net patient revenue: $3.4 billion in its latest full-year cost report, with 681 beds and an operating margin of -1.7%.
It is how much a hospital keeps from patient care after paying its operating costs, as a share of its patient revenue. A margin of 5% means the hospital kept 5 cents of every dollar it earned from patients; a negative margin means patient care cost more than it brought in. It excludes donations, investment income and grants.
