Breaking down U.S. hospital payor mixes
Understanding a hospital’s payor mix gives insight into the organization’s financial health and performance.
This Healthcare Insight reviews payor mix data for more than 5,700 U.S. hospitals and compares the results by hospital type, size, and location.
What is payor mix in healthcare?
Payor mix data represents the breakdown of revenues, charges, discharges, and patient days from different medical insurance payors. In the Definitive Healthcare HospitalView product, the proprietary calculation is based on a facility’s charge and revenue measures from the Medicare Cost Report.
What is the difference between payer and payor?
For the U.S. healthcare market, the terms “payor” and “payer” are often used interchangeably and have the same general meaning. The American Medical Association (AMA) recognizes “payor” as the preferable spelling.
Payor mix classifications
Payor mix breaks down into the following classifications: Medicare, Medicaid, and commercial/private/self-pay/other. Specifically, these payor mix categories are defined as:
Medicare: charges from beneficiaries who are 65 and older, or certain people under 65 with a disability, end-stage renal disease, amyotrophic lateral sclerosis, etc., and are part of the Medicare program.
Medicaid: charges from beneficiaries who are part of state Medicaid programs (also includes Medicaid Managed Care charges).
Commercial/private/self-pay/other: charges from any patients who have health insurance through their employer or marketplaces, those who do not have insurance or choose to self-pay, Medicare Advantage patients, and all other patients.
How is hospital payor mix calculated?
Using hospital revenue and charge data, we can estimate the allocation of revenue sources to derive individual hospital payor mixes. For example, if we know a hospital’s total patient revenue is $100 million, its Medicare revenue is approximately $25 million, and its Medicaid revenue is approximately $10 million, we could calculate a 25% Medicare, 10% Medicaid, and 65% commercial/private/self-pay payor mix.
What is the payor mix breakdown?
Results in the following analysis are aggregated from the most recent complete 12-month interval tracked in our database. The most recent full calendar year of data available for all hospitals at the time of publishing is for 2023. About half of the hospitals in our database have reported payor mix data for 2024 as of August 2025.
Commercial, private, and self-pay represent the largest payor group for U.S. hospitals with net patient revenue of more than $849 billion, or 69.9% of average payor mix.
Total net patient revenue for Medicare was more than $188 billion in 2023, or 15.5% of payor mix. Medicaid’s total net revenue was more than $177 billion or 14.6% of payor mix distribution.
In addition to revenue allocation, payor mix can also be analyzed by the percentage of patient days. For example, since Medicare patients represent an older population, patient cases might be more complex or patient comorbidities may lead to longer hospital stays.
Payor mix by total patient days breaks down as follows:
- Commercial/private/self-pay/other: 67.5%
- Medicare: 23.9%
- Medicaid: 8.6%

How has hospital payor mix breakdown changed year-to-year?
Medicaid enrollment increased with the expansion of the Affordable Care Act (ACA) and through the COVID-19 pandemic. In addition, the country faces an aging of the American population. With these factors potentially leading to larger Medicare and Medicaid populations, surprisingly, trends for Medicare and Medicaid payor mix show decreases in hospital patient days. Since 2014, the percentage of Medicare patient days decreased from 34.1% to 23.9% in 2023, and Medicaid patient days decreased from 13.0% to 8.6% in the same timeframe.
The percentage of commercial/private/self-pay patient days at U.S. hospitals has increased over the last 10 years from 53.0% in 2014 to 69.9% in 2023. In addition to rising healthcare costs, this could also reflect the increase in Medicare Advantage enrollment, which are Medicare Part C plans offered by commercial/private payors approved by Medicare.

What is the payor mix breakdown by hospital bed size?
Hospitals with 25 or fewer beds have the highest Medicare patient days, where more than 42% of patient days are for Medicare patients. In comparison, hospitals with more than 250 beds have more than two-thirds of patient days from commercial/private/self-payors.
The percentage of payor days generally correlates to hospital bed count, where the percentage of Medicare days declines and the percentage of commercial/private/self-pay days increases relative to a hospital’s number of beds. Facility specialties, insurance coverage, and hospital service area demographics likely contribute to these differences.

What is the payor mix breakdown by hospital type?
The highest percentage of Medicaid and commercial/private/self-pay patient days are at psychiatric hospitals and children’s hospitals, respectively. Rehabilitation hospitals have more than half of their patient days coming from private payors, while critical access hospitals had nearly half from this same group.

What is the payor mix breakdown by hospital location?
Comparing the payor patient days by hospital region shows fairly similar results. Some differences include the Northeast and Midwest having the highest percentage of Medicare days. Hospitals in the Midwest have the lowest average number of beds, and the analysis above shows that smaller hospitals tend to have higher Medicare patient days.
In addition, hospitals in the West and U.S. territories have the least Medicare days and the most Medicaid days. California, Hawaii, and Alaska, for example, have some of the highest Medicaid payor mixes by state, contributing to the regional result.
Southern hospitals have more payor days from commercial/private/self-payors. Some of the largest hospitals in the U.S. by beds are located in the south, and larger hospitals tend to have higher commercial/private/self-pay days, according to our analysis above.

Why does payor mix matter for commercialization?
Payor mix allocations help companies that sell and market to hospitals better segment and target accounts.
For example, if a durable medical equipment product is covered by Medicare, the sales team may want to prioritize hospitals with higher Medicare payor mixes. Or, if a new diagnostic test is not yet covered by insurance, the healthcare marketing team might first include hospitals with the highest commercial/private payor mixes in their email campaign.
