Top 20 Health Systems by Total Revenue
Of course given its status as an integrated health plan, Kaiser takes the total revenue crown. But if you’re looking at mostly patient services revenue (the next table), HCA reigns supreme by a wide margin over its nonprofit and for-profit counterparts.

Top 20 Health Systems by Patient Revenue
You can see all of the typical names here on the patient revenue side (excluding Kaiser, which hasn’t completed its audit, nor do I think they break out the patient revenue generated on the provider side of the business). Advocate has secured its spot in the top 3 given its recent merger with Atrium and the second year of combined financials. Ascension slid into 4th given its asset sales, and so on.

Top 20 Health Systems by Patient Revenue Growth
Several names on the list saw spikes or drops in revenues from divestitures or portfolio add-ons. Novant Health comes to mind here in tacking on several Tenet hospitals. BJC just merged with Saint Luke’s. Wellstar merged with August University Health System. On the other side of the growth equation, Tenet and Ascension come to mind as notable players who either saw no revenue growth, or declines in patient revenue growth stemming from hospital divestitures for portfolio realignment purposes. Health systems like Henry Ford and Prime Healthcare picked up a material amount of Ascension’s book of business. I covered Ascension’s whole 2024 portfolio realignment here.

The Full List
Here’s the full list of 80 or so health system names updated through calendar year 2024. The names highlighted in orange either just announced a significant merger, or closed on in recent years. For instance, Northwell-Nuvance, BJC-Saint Luke’s, Sanford-Marshfield, and Kaiser/Risant-Cone-Geisinger as a few examples.
