Taxpayers pay for prisoner health care in the United States. The government is constitutionally required to provide medical care to incarcerated people, and that obligation is funded through federal, state, and local budgets. The total cost of incarcerating a single federal inmate averaged $44,090 per year in fiscal year 2023, with health care consuming a significant share of that figure.
Why the Government Is Legally Required to Pay
The obligation traces back to a 1976 Supreme Court case, Estelle v. Gamble, which established that “deliberate indifference to serious medical needs of prisoners” violates the Eighth Amendment’s ban on cruel and unusual punishment. The reasoning is straightforward: when the government takes away someone’s freedom, it also takes away their ability to seek medical care on their own. That creates a duty to provide it.
This duty applies broadly. It covers prison doctors who ignore a patient’s symptoms, guards who intentionally delay someone’s access to treatment, and staff who interfere with prescribed care. The standard isn’t perfection. Simple negligence or a disagreement about the best treatment doesn’t rise to a constitutional violation. But intentionally ignoring a serious medical problem does, and inmates can sue over it in federal court.
How the Cost Splits Between Federal, State, and Local Government
The level of government that runs the facility generally pays for health care inside it. Federal prisons are funded through the Bureau of Prisons budget, which drew from roughly $6.9 billion in total budgetary resources in fiscal year 2026. State prisons pull from state general funds. County jails rely on local budgets, which often means county taxpayers bear the cost directly.
One major restriction shapes how this money flows. The Social Security Act, which created Medicaid in 1965, includes what’s known as the “inmate exclusion policy.” It prohibits federal health insurance programs, including Medicaid and Medicare, from covering medical care for people in correctional facilities. The only exception is hospitalizations lasting more than 24 hours. So even if an inmate was enrolled in Medicaid before being locked up, that coverage is suspended (not canceled) for the duration of their incarceration. The state or county picks up virtually all routine health costs instead.
This creates an enormous financial burden. States can’t tap into the federal matching funds that Medicaid normally provides, so they’re paying 100 cents on every dollar of care delivered behind bars.
Private Companies That Deliver the Care
Many state and local governments don’t run health services in-house. Instead, they contract with private corporations. Two of the largest prison health care companies in the country are owned by private equity firms, and they operate across multiple states. The business model centers on winning a fixed-price contract and keeping costs below that amount.
This structure has drawn serious scrutiny. A 2019 CNN investigation found that one major provider’s focus on “cost containment” contributed to patient deaths. In Alabama, another company employed just 15 physicians to cover a contract serving 25,000 prisoners. When the financial incentive is to spend as little as possible on care, the quality of that care often suffers. Lawsuits, investigations, and legislative hearings over inadequate prison health care have become routine in many states.
What Inmates Pay Out of Pocket
At least 35 states authorize charging inmates co-payments or other fees for medical visits. These fees are small in absolute terms, typically $2 to $13, but they represent a much larger share of a prisoner’s income than a co-pay does in the outside world. A 2017 study found that 14 states charge medical co-payments that, relative to prison wages, would be equivalent to charging a minimum-wage worker over $200 per visit.
The effects are predictable. When Illinois charged a $5 co-pay, more than 60 percent of prisoners reported avoiding medical care because of the cost. Illinois eliminated the fee in 2019. California has also ended its $5 co-pay. Texas, which once charged a notorious $100 fee per medical visit, reduced it to $13.55. These fees are typically deducted from an inmate’s commissary account, the small balance they accumulate through prison jobs or money sent by family. When someone earns pennies per hour, even $5 is a meaningful deterrent.
Emergency care, chronic disease management, and mental health crises are generally exempt from co-pays. The fees apply mostly to sick calls, the prison equivalent of a walk-in doctor visit.
Why Costs Keep Rising
The prison population is aging, and that’s the single biggest driver of escalating health care costs behind bars. Older inmates cost two to three times more than younger inmates by commonly cited government estimates, though some state-level analyses put the figure at three to nine times as much. Chronic conditions like diabetes, heart disease, and hepatitis C are far more prevalent in prisons than in the general population, partly because many inmates had limited access to preventive care before incarceration.
Mental health and substance use disorders add another layer. A large share of the incarcerated population has at least one behavioral health condition, and providing adequate psychiatric care and medication is expensive. Specialty care, including surgeries and cancer treatment that require transport to outside hospitals, can generate enormous bills for a single inmate.
A Policy Shift Already Underway
The strict wall between Medicaid and incarceration is starting to crack. Through a federal program called Section 1115 demonstration waivers, the Centers for Medicare and Medicaid Services now allows states to use Medicaid funds for health care services delivered to inmates shortly before their release. The goal is to improve the transition back into the community, particularly for people with substance use disorders and serious mental illness who are at high risk of overdose, relapse, or emergency hospitalization in the weeks after leaving prison.
As of now, 18 states have received approval for these reentry demonstrations: Arizona, California, Colorado, Hawaii, Illinois, Kentucky, Maryland, Massachusetts, Montana, New Hampshire, New Mexico, North Carolina, Oregon, Pennsylvania, Utah, Vermont, Washington, and West Virginia. The programs vary in scope, but they generally cover behavioral health treatment, care coordination, and medication management starting 30 to 90 days before an inmate’s release date. This doesn’t change the fundamental rule that Medicaid won’t pay for routine care during incarceration, but it does represent the most significant federal policy shift on this issue in decades.
