Which health systems have the most revenue?
Net patient revenue is what hospitals collect for patient care after discounts and contractual allowances, as reported on their Medicare cost reports. The table ranks systems by the sum of their member hospitals' net patient revenue and adds two ratios computed by DataPorium: revenue per bed, and net income as a share of net patient revenue. Net income includes other income such as investment returns and donations [1].

Ratios computed by DataPorium. Star ratings are the average Medicare overall rating (1 to 5) of the system's rated hospitals.
What stands out
HCA's revenue is 1.8 times CommonSpirit's, and its $15.54 billion of net income is larger than the next five systems' combined net income of $6.87 billion [1]. Academic systems earn the most per bed: Mayo Clinic ($4.54 million) and Mass General Brigham ($4.26 million) bring in roughly three times HCA's $1.53 million [1]. Universal Health Services has the lowest revenue per bed in the top 15, $0.63 million; only 29 of its 151 hospitals are short-term acute care hospitals [1].
Ratings point the other way from size. The three for-profit chains in the top 15 average 2.22 to 2.94 stars across their rated hospitals, while Mayo Clinic, Mass General Brigham and Cleveland Clinic average above 4 [1].

How we ranked the health systems
- Health system: two or more hospitals under one home office or common ownership in the official Medicare ownership and cost report records, completed with a 2023 list of US health systems; current ownership records win when the two disagree. DataPorium tracks 761 systems [1].
- Hospitals and beds: active Medicare-certified hospitals of each system (hospital list as of April 1, 2026), of every type: acute care, critical access, psychiatric, rehabilitation, long-term care and others [1].
- Revenue and income: from each member hospital's latest full-year Medicare cost report (data as of March 5, 2026); for most hospitals that is the fiscal year ending in 2025, for some it is 2024 [1]. These figures cover the hospitals only and are not the same as the revenue the companies report to investors.
- Per-bed and margin ratios: computed by DataPorium from the figures in the table.
