Understanding how hospitals are financed through various insurance payors provides critical insights into their financial stability and operational focus. This comprehensive review examines the distribution of payor types across thousands of U.S. hospitals, offering an in-depth look at how funding sources vary by hospital size, type, and geographic location.
Hospitals derive their revenue from a mix of payors, including government programs like Medicare and Medicaid, as well as private insurers and self-paying patients. Grasping the nuances of this payor mix is essential for stakeholders aiming to optimize revenue streams, develop targeted marketing strategies, or implement efficient payment systems. This analysis leverages data from the Definitive Healthcare HospitalView product, which utilizes information from the Medicare Cost Report to provide a detailed picture of hospital revenue sources.
What Is Hospital Payor Mix?
Payor mix refers to the proportion of hospital revenue generated from different types of insurance payors. It encompasses metrics such as total charges, revenue, discharges, and patient days attributable to each payor category. This data is typically calculated based on a hospital’s charge and revenue figures, with tools like the Medicare Cost Report serving as a foundation for these estimations. By understanding the distribution of revenue across payor types, hospital administrators and analysts can better assess financial health and identify areas for growth or improvement.
Difference Between Payer and Payor
In the context of the U.S. healthcare system, the terms “payor” and “payer” are often used interchangeably. However, the American Medical Association (AMA) officially favors the spelling “payor.” Both terms refer to entities—whether government programs or private insurers—that finance healthcare services for patients. Clarifying this terminology is important for accurate communication and documentation within healthcare data analysis.
Payor Mix Classifications
Hospital payor mixes are generally categorized into three broad groups:
-
Medicare: Revenue from patients aged 65 and older or certain younger individuals with disabilities, including those with end-stage renal disease or amyotrophic lateral sclerosis. These patients are covered under the Medicare program.
-
Medicaid: Revenue derived from state-sponsored programs providing coverage for low-income individuals and families. This category also includes Medicaid Managed Care charges.
-
Commercial, Private, Self-Pay, and Other: This group includes revenue from patients with employer-sponsored insurance, marketplace plans, those who pay out-of-pocket without insurance, Medicare Advantage enrollees, and other miscellaneous payors.
Calculating Hospital Payor Mix
Estimating a hospital’s payor composition involves analyzing revenue and charge data. For example, if a hospital reports a total patient revenue of $100 million, with approximately $25 million from Medicare and $10 million from Medicaid, the payor distribution would be roughly 25% Medicare, 10% Medicaid, and 65% from private or self-pay sources. This breakdown helps identify dominant revenue streams and potential vulnerabilities.
What Is the Typical Payor Mix Breakdown?
Based on recent data covering the full year of 2023, hospitals’ revenue distributions reflect the predominance of private insurance, which accounts for nearly 70% of total net patient revenue—approximately $849 billion. Medicare revenue topped $188 billion, representing about 15.5% of the payor mix, while Medicaid contributed over $177 billion, or roughly 14.6%.
In addition to revenue figures, payor mix can be analyzed through patient days, revealing patient demographics and complexity. Since Medicare patients tend to be older with more comorbidities, they often require longer hospital stays, influencing the patient day distribution:
- Commercial/private/self-pay/other: 67.5%
- Medicare: 23.9%
- Medicaid: 8.6%

How Has the Hospital Payor Mix Changed Over Time?
The distribution of payor types has evolved notably over recent years. Medicaid enrollment expanded significantly due to the Affordable Care Act (ACA) and the COVID-19 pandemic, while the aging U.S. population has increased demand for Medicare services. Interestingly, despite these trends, the proportion of hospital days attributed to Medicare and Medicaid has decreased: Medicare patient days declined from 34.1% in 2014 to 23.9% in 2023, and Medicaid days fell from 13.0% to 8.6%. Conversely, the share of patient days covered by private insurance has grown from 53.0% to nearly 70% during the same period.
This shift may be partly driven by the rise in Medicare Advantage plans, which are private plans approved by Medicare but managed outside traditional fee-for-service arrangements. These trends demonstrate the dynamic nature of hospital funding sources and the importance of adapting revenue strategies accordingly.

Payor Mix by Hospital Bed Size
Hospital size influences the payor composition significantly. Smaller hospitals—those with 25 or fewer beds—see over 42% of their patient days from Medicare, reflecting their role in serving aging or complex patient populations. Larger hospitals, especially those with more than 250 beds, derive the majority of their patient days from private payors, exceeding two-thirds of total days.
Generally, as hospital size increases, the proportion of Medicare days decreases while private insurance days increase. These differences are influenced by the hospital’s specialty, geographic location, and the demographic characteristics of the surrounding community.

Payor Mix Variations by Hospital Type
Different hospital types tend to have distinct payor profiles. Psychiatric hospitals report the highest percentage of Medicaid days, aligning with their patient populations. Children’s hospitals, on the other hand, see a larger share of days from private payors, reflecting the insurance coverage typically available for pediatric care. Rehabilitation hospitals tend to have more than half of their patient days covered by private payors, while critical access hospitals have nearly half from this group.

Regional Differences in Payor Mix
When comparing regions across the U.S., payor distributions remain relatively stable, but notable differences exist. The Northeast and Midwest regions have higher percentages of Medicare days, possibly due to older populations and hospital types prevalent in these areas. Conversely, the Western states and U.S. territories, such as California, Hawaii, and Alaska, show higher Medicaid proportions, influenced by state-level policies and demographics.
Hospitals in the South tend to have a larger share of days from private payors, correlating with the presence of some of the country’s largest hospitals by bed count, which often serve diverse and insured populations.

Why Payor Mix Matters for Healthcare Commercialization
Understanding a hospital’s payor composition is vital for healthcare companies aiming to improve their market targeting and sales strategies. For instance, if a medical device or diagnostic test is predominantly covered by Medicare, sales efforts might focus on hospitals with higher Medicare payor percentages. Conversely, for products not yet covered by insurance, targeting hospitals with substantial private payor populations could be more effective.
Accurate payor analysis supports strategic planning, product positioning, and risk assessment, ultimately enhancing revenue growth and market penetration.
