Uncompensated care is the sum of medical services that hospitals and other providers deliver but never get paid for. It consists of two parts: charity care, where the provider knowingly treats someone without expecting payment, and bad debt, where the provider bills a patient but ultimately cannot collect. In 2013, the national tab for uncompensated care was estimated between roughly $75 billion and $85 billion, with government programs offsetting about two-thirds of that cost. The rest falls on hospitals themselves, on privately insured patients through higher prices, and on taxpayers at the federal, state, and local levels through a tangle of programs that few people outside health policy circles fully understand.
Charity Care Versus Bad Debt
The distinction between the two halves of uncompensated care matters more than it might seem. Charity care is intentional: a hospital decides in advance, or shortly after treatment, that it will not bill a patient, usually because the patient meets income thresholds set by the hospital’s financial assistance policy. Bad debt is the opposite experience. The hospital sends a bill, expects to be paid, and eventually writes off the balance after collection efforts fail. From the hospital’s ledger these look like different line items, but from the patient’s perspective the difference can be enormous. A patient whose care is classified as charity faces no collection calls, no lawsuits, no credit damage. A patient whose identical bill is classified as bad debt may face all three before the hospital finally gives up.
Hospitals have some discretion in how they categorize a given case, and accounting standards have shifted over time. Some hospitals are more aggressive about reclassifying accounts from bad debt to charity care after the fact, which can inflate their reported community benefit numbers. That gray area is one reason policy researchers often lump the two together under the single heading “uncompensated care” when studying the financial health of the hospital sector.
The National Price Tag
The most thorough estimate of uncompensated care across all provider types pegged the total at between $74.9 billion and $84.9 billion in 2013. That study found that at least 65 percent of providers’ uncompensated care costs were offset by government payments, with Medicaid contributing about $13.5 billion and Medicare about $8 billion in dedicated subsidies.1Health Affairs. Uncompensated Care For The Uninsured In 2013: A Detailed Investigation Those numbers have shifted since 2013, particularly after the Affordable Care Act’s coverage expansions, but the basic structure remains: the federal government picks up the largest share, states and localities contribute a significant slice, and hospitals absorb whatever is left.
The trajectory over decades has not been a smooth upward line. Rapid growth in uncompensated care from 1983 to 1986 was followed by modest growth through 1990, another spurt in the early 1990s, and a leveling off through the mid-1990s.2PubMed. A profile of uncompensated hospital care, 1983-1995 Each swing coincided with changes in insurance coverage, Medicaid payment policy, and the broader economy. Recessions push more people into uninsured status, which pushes more hospital visits into the uncompensated column.
Why Insurance Status Is the Biggest Driver
If you want to predict whether a hospital visit will end up as uncompensated care, the single strongest variable is whether the patient has insurance. A study of Florida hospitals found that patients with no coverage were nearly 39 times more likely to have an outstanding hospital balance than patients with some form of insurance. After researchers controlled for income, demographics, and the circumstances of admission, the odds jumped even higher, to roughly 74 times more likely.3PubMed. Determinants of the uncompensated care burden of rural and urban hospitals in Florida That finding is from a Florida-specific dataset and older data, but the underlying dynamic has not changed: insurance transforms an unpayable bill into a mostly-paid claim.
This is why discussions about uncompensated care inevitably circle back to the uninsured. Even underinsured patients, people who have coverage with high deductibles or narrow networks, generate some bad debt. But the sheer scale of uncompensated care is driven overwhelmingly by visits where no payer exists at all. Hospitals in communities with larger uninsured populations carry heavier loads, and safety-net hospitals that serve low-income areas absorb a disproportionate share.
Federal Programs That Offset the Cost
The federal government does not write a single check labeled “uncompensated care reimbursement.” Instead, it channels money through several programs that partially cover the gap. The largest are Disproportionate Share Hospital (DSH) payments through both Medicaid and Medicare. These are add-on payments directed to hospitals that treat a high share of low-income or uninsured patients. Safety-net hospitals rely on DSH payments to help cover uncompensated care costs and the shortfall between what Medicaid actually pays and what care costs to deliver.4PubMed Central. Disproportionate-Share Hospital Payment Reductions May Threaten The Financial Stability Of Safety-Net Hospitals
How well these payments are targeted is another question. Research has found that little is known about how Medicaid DSH payments are allocated across hospitals or whether the money reliably reaches the facilities with the greatest uncompensated care burden.5PubMed. Variation And Changes In The Targeting Of Medicaid Disproportionate Share Hospital Payments Some states distribute DSH funds broadly, while others concentrate them in a few large urban safety-net systems. When Congress reduced DSH payments through the 1997 Balanced Budget Act, researchers studied whether hospitals responded by cutting back on the amount of uncompensated care they provided, a question that gets at whether DSH funding actually enables charity care or simply subsidizes hospital finances more generally.6PubMed Central. Medicaid Disproportionate Share Hospital payment: how does it impact hospitals’ provision of uncompensated care?
State and Local Contributions
Below the federal layer, states and localities spend billions of their own money caring for the uninsured. One estimate put the combined state and local contribution at roughly $9.9 billion, with the bulk, about $7.7 billion, coming from tax appropriations for indigent care programs. An additional $2.2 billion flowed through state and local public assistance programs.7Health Affairs. What Is Uncompensated Care and Who Pays for It? These programs vary wildly from state to state. Texas, for example, has historically operated large county hospital districts funded by local property taxes, while other states fold indigent care into their Medicaid programs or fund it through general revenue.
The patchwork nature of state funding means that where you live shapes how much uncompensated care your local hospital can absorb and how visible the cost is to taxpayers. In states with generous programs, some of the cost is explicitly budgeted and debated. In states with minimal programs, the cost is more likely to show up as hospital losses or higher charges to insured patients.
The Cost-Shifting Debate
One of the most persistent claims in health policy is that hospitals recoup uncompensated care losses by charging privately insured patients more, a practice called cost shifting. The logic sounds straightforward: if Medicare and Medicaid underpay, and uninsured patients cannot pay at all, hospitals make up the difference by inflating prices for commercial insurers, who then pass those costs along as higher premiums. Insurance industry groups have long pointed to cost shifting as a major driver of premium growth.
The evidence, however, is considerably messier than the theory. A comprehensive review of cost-shifting studies concluded that policymakers should view hospital and insurance industry claims of inevitable, large-scale cost shifting with skepticism. While some cost shifting does occur in response to changes in public payment rates, it is just one of many possible hospital responses, and it does not happen dollar for dollar.8PubMed Central. How much do hospitals cost shift? A review of the evidence Hospitals may also respond to revenue shortfalls by cutting costs, reducing services, or simply running thinner margins. A historical analysis of cost-shifting patterns since 1980 found that cost-shifting pressures fluctuate over time and across markets, and that hospitals can absorb some degree of cost-shifting pressure through increased efficiency.9PubMed. The cost-shift payment ‘hydraulic’: foundation, history, and implications
So yes, privately insured patients and their employers likely bear some portion of uncompensated care costs through higher prices. But the relationship is not the simple hydraulic that industry talking points suggest. Market power, negotiating dynamics between hospitals and insurers, and hospital management decisions all mediate how much cost actually gets shifted and to whom.
How Medicaid Expansion Changed the Picture
The Affordable Care Act’s Medicaid expansion, which allowed states to extend coverage to adults earning up to 138 percent of the federal poverty level, was designed in part to reduce uncompensated care. The early evidence showed that it worked, at least in the states that adopted it. In expansion states, uncompensated care costs dropped from about 4.1 percent of hospital operating costs to 3.1 percent. Researchers estimated that if non-expansion states had also expanded Medicaid, their uncompensated care costs would have fallen from about 5.7 percent to 4.0 percent of operating costs.10PubMed. Uncompensated Care Decreased At Hospitals In Medicaid Expansion States But Not At Hospitals In Nonexpansion States
The benefits were not evenly distributed across all hospitals. Within expansion states, safety-net hospitals that had been carrying the heaviest uncompensated care loads saw the largest reductions. The Medicaid expansion significantly reduced hospital provision of uncompensated care in 2014, and DSH hospitals within expansion states saw reductions beyond those experienced by non-DSH hospitals.11PubMed Central. The ACA Medicaid Expansion, Disproportionate Share Hospitals, and Uncompensated Care That pattern makes sense: the patients who gained Medicaid coverage were disproportionately the same patients who had been generating uncompensated care at those hospitals.
A comparison of Washington (which expanded Medicaid) and Idaho (which did not expand until later) found that expansion was associated with lower uncompensated care costs per hospital bed, alongside higher Medicaid revenue.12PubMed. The effect of medicaid expansion on hospital finances: evidence from Washington and Idaho The tradeoff, however, is that Medicaid typically pays hospitals less than commercial insurance and sometimes less than the cost of care. Hospitals gained paying patients but at Medicaid rates, so the net financial effect was more complicated than simply plugging a hole.
Emergency Departments and the Legal Mandate to Treat
The Emergency Medical Treatment and Labor Act, known as EMTALA, requires any hospital that accepts Medicare (which is nearly all of them) to screen and stabilize anyone who shows up at the emergency department, regardless of ability to pay. EMTALA does not pay for the care it mandates. It simply requires that hospitals provide it. This federal mandate means that emergency departments serve as the de facto safety net for millions of uninsured Americans, a role that generates a substantial share of hospital uncompensated care.
Research on emergency department payment patterns found that declining overall payment rates were threatening the ability of EDs to continue providing care to all comers, and that cost shifting to fund care for the uninsured was becoming an increasingly untenable financing strategy.13PubMed. Declining payments for emergency department care, 1996-1998 This tension has not eased. Emergency departments remain the most expensive setting for delivering uncompensated care, and the mandate to treat without a corresponding mandate to fund creates a structural gap that every other financing mechanism is trying, imperfectly, to fill.
Nonprofit Hospitals and Their Tax-Exempt Bargain
About half of all community hospitals in the United States are nonprofit, which means they are exempt from federal, state, and local taxes. In exchange, they are expected to provide community benefits, including charity care. The question of whether nonprofit hospitals hold up their end of this bargain has become increasingly contentious. One analysis estimated that the total value of tax exemptions enjoyed by nonprofit hospitals was about $28 billion in 2020, while total charity care costs at those same hospitals came to roughly $16 billion.14Health Affairs. What Is Uncompensated Care and Who Pays for It?
Nonprofits point out that charity care is only one component of community benefit, which can also include medical education, research, subsidized health services, and community health improvement activities. Critics counter that many nonprofit hospitals spend less on charity care than for-profit hospitals in the same markets, and that the community benefit reporting framework is loose enough to let hospitals count activities that primarily benefit their own bottom line. The gap between $28 billion in tax breaks and $16 billion in charity care is not proof that nonprofits are freeloading, but it does raise fair questions about whether the public is getting a good return on the exemption.
Community Health Centers as the Other Safety Net
Hospitals are not the only providers absorbing uncompensated care. Federally Qualified Health Centers (FQHCs) serve as the primary care safety net for millions of low-income and uninsured Americans. These community-based clinics receive federal grants specifically to enable them to treat patients regardless of ability to pay, and the proportion of a center’s patient mix that is uninsured is the key driver of how much uncompensated care it provides.15PubMed Central. When Patients Govern: Federal Grant Funding and Uncompensated Care at Federally Qualified Health Centers
Federal investment in FQHCs has translated into measurably more care for the uninsured. An analysis of funding trends from 1996 to 2006 found that an additional $500,000 in federal grants translated into about 540 more uninsured patients treated at a given health center.16PubMed. Funding growth drives community health center services FQHCs also tend to deliver care more cheaply than emergency departments, making them a more efficient vehicle for absorbing uncompensated care. But their capacity is limited. When grant funding stalls or gets cut, uninsured patients often have no alternative except the hospital ED, which circles back to the more expensive setting.
When Hospitals Pursue Patients for the Bill
Not all uncompensated care stays uncompensated quietly. Before a hospital writes off a balance as bad debt, it may pursue the patient aggressively. Some of the nation’s largest hospitals have adopted what researchers call extraordinary collection actions: lawsuits, wage garnishments, and liens against patients’ property for unpaid medical bills.17BMJ Open. Characteristics of US hospitals using extraordinary collections actions against patients for unpaid medical bills: a cross-sectional study Federal rules require nonprofit hospitals to notify patients and observe waiting periods before taking these steps, but the rules do not ban the practices themselves.
State-level protections vary enormously. Most states, 38 of them, do not exceed the federal standard on billing and collections practices. Only three states fully prohibit the sale of medical debt to third-party collectors, and just a handful impose other restrictions such as prohibiting debt sales for low-income patients or while a patient is current on a payment plan.18The Commonwealth Fund. State Protections Against Medical Debt: A Look at Policies Across the U.S. in 2025 For patients caught in this gap, the line between uncompensated care and medical debt is not an accounting abstraction. It is the difference between a forgiven balance and a garnished paycheck.
The irony is that aggressive collection often recovers little money relative to the financial and reputational cost. Many patients pursued through lawsuits or wage garnishment are low-income and would have qualified for charity care if they had navigated the financial assistance application process. Several high-profile investigations in recent years have revealed hospitals suing patients who were, on paper, eligible for free care. That pattern has pushed more hospitals to screen for financial assistance eligibility before sending accounts to collections, though the practice is far from universal.
How Uncompensated Care Hits Rural Hospitals Differently
Rural hospitals face a version of the uncompensated care problem that is structurally harder to solve. They tend to serve smaller, older, and lower-income populations, and they lack the volume of commercially insured patients that urban hospitals use to cross-subsidize unpaid care. A rural critical access hospital with 25 beds simply cannot spread losses the way a 500-bed urban medical center can. When a single uninsured patient requires an expensive surgery or a lengthy stay, the financial impact on a small rural facility can be severe in a way that would barely register on a large system’s balance sheet.
Rural hospitals are also less likely to benefit from DSH payments, since the allocation formulas tend to favor larger facilities with higher absolute numbers of low-income patients. A rural hospital might serve a community where half the population is uninsured but still receive less DSH funding than an urban hospital with a lower percentage of uninsured patients but far more total discharges. This mismatch has contributed to a wave of rural hospital closures, particularly in states that did not expand Medicaid. When a rural hospital closes, the uncompensated care it was providing does not disappear. It migrates to the next nearest facility, to emergency medical services covering longer transport distances, or it goes undelivered entirely.
What Happens to Uncompensated Care Costs That Nobody Covers
After government subsidies, tax exemptions, and whatever cost shifting the market will bear, a residual amount of uncompensated care remains truly uncompensated. Hospitals absorb this as an operating loss. For large, financially healthy systems, the loss is manageable, a line item that cuts into margins but does not threaten survival. For smaller or financially fragile hospitals, particularly those in low-income communities where uncompensated care is highest, the loss can be existential.
Hospitals respond to chronic uncompensated care losses in ways that rarely make headlines but affect patients directly. They may reduce staffing, defer maintenance, cut service lines that lose money (behavioral health and obstetrics are common casualties), or avoid investing in technology. Over time, these responses degrade the quality and availability of care in exactly the communities that generate the most uncompensated care, creating a feedback loop in which the most vulnerable populations have access to the most financially stressed providers. Coverage expansions like Medicaid can interrupt that cycle, but they do not eliminate it, because even Medicaid pays below cost in many states, and some portion of the population remains uninsured regardless of the policy environment.
