US Healthcare System: 3 Competing Goals, Explained Simply

Last updated 7 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

The US healthcare system is judged against three goals: access, cost and quality. In plain terms: can people get care, who pays for it and how well does it work? The country spent $15,474 per person on health in 2024, and 26.7 million people went all of 2025 uninsured.

The goals can pull against each other, but improving one does not have to mean sacrificing another. They are also easy to confuse: a reform can cost the federal government more while costing the country less, because moving a bill is not the same as shrinking it. Government insurance, tax rules and payments to providers connect all three goals, so the details of a reform matter as much as its label.

Three goals, measured separately

Access means being able to obtain needed care, not simply being counted as insured. The Organisation for Economic Co-operation and Development (OECD) evaluates access through the affordability, availability and use of services, and evaluates care quality through safety, effectiveness and responsiveness to people’s needs.

Cost also needs a definition: a patient’s bill, a government budget and the nation’s spending are different totals. Quality asks what the care accomplishes and how safely it is delivered, rather than how expensive it is.

The Institute for Healthcare Improvement’s Triple Aim calls for simultaneous improvement in care experience and population health while reducing per-person costs. That is a goal for improvement, not a law that every change must help one aim by damaging another. Avoiding an unnecessary service is a different kind of cost reduction from making needed care harder to obtain.

Why coverage comes from several places

The coverage picture is a mixture, with employer plans the largest source.

These Census Bureau categories overlap because people can have more than one type of coverage during a year.

Medicare covers people age 65 or older who meet citizenship or residency requirements, with earlier eligibility possible for people with disabilities or end-stage renal disease. End-stage renal disease means permanent kidney failure requiring regular dialysis or a kidney transplant. Medicare’s Part D prescription-drug plans are run by private insurers that follow rules set by Medicare. Public financing and private administration can therefore coexist within one program.

Medicaid covers eligible low-income adults, children, pregnant women, older adults and people with disabilities; states administer it under federal requirements, with joint state and federal funding.

A 1943 ruling held that qualifying employer contributions for group medical and hospital insurance were not taxable income to workers, according to a Congressional Research Service history. President Lyndon B. Johnson signed the legislation establishing Medicare and Medicaid on July 30, 1965. The Affordable Care Act, enacted in March 2010, added premium tax credits and expanded Medicaid to cover all adults under an income limit, an expansion not all states have adopted. Premium tax credits help eligible households pay their monthly premiums for Marketplace plans, the health plans people can compare and enroll in through HealthCare.gov.

These layers help explain why the United States has several routes to coverage rather than one central insurer.

Access means more than an insurance card

The Census Bureau estimated that 26.7 million people, or 7.9 percent, were uninsured throughout 2025, not statistically different from 2024. That measure identifies a coverage gap; it does not show whether everyone with insurance could obtain affordable treatment.

A premium is the monthly payment for health insurance. A deductible is the amount paid for covered care before the plan starts paying, although certain services, including Marketplace preventive benefits, are covered before it is met. A copayment is a fixed payment for a covered service, usually made when the service is received. Coinsurance is a percentage of the allowed cost of a covered service, generally paid in addition to any deductible still owed. An insured household can therefore owe more than its premium.

Choice of insurer is not the same as unrestricted choice of clinician. Exclusive provider organizations cover services only from doctors, specialists or hospitals in the plan’s network, except in an emergency, while health maintenance organizations generally limit covered care to contracted providers with an emergency exception.

A coverage expansion also does not itself put a hospital closer to someone’s home. In a review of five urban hospital closures, the Government Accountability Office found that available services shifted or decreased in all five communities; two hospitals retained outpatient services and three stopped providing care. This is a finding about selected communities, not a count of shortages nationwide.

The Commonwealth Fund’s US health-system profile describes disparities in care and outcomes affecting racial and ethnic minority groups, low-income families and rural populations. Equity asks who still faces the barriers when a national average improves.

The cost of care, and who pays it

The Centers for Medicare & Medicaid Services (CMS) reports that national health spending reached $5.3 trillion in 2024, or $15,474 per person and 18 percent of gross domestic product. Its national accounts include care goods and services, public health activities, administration, insurance expenses unrelated to medical care and health-related investment. The per-person figure is a national accounting average, not an annual bill sent to each resident.

Those spending shares answer who paid, whereas the Census coverage shares answer who was insured.

Private insurers use premium revenue to pay covered claims and administrative expenses, including taxes and fees. Employer premium contributions are excluded from employee gross income and are not subject to federal income or payroll taxes, according to the Congressional Research Service’s private insurance primer.

Medicare hospital insurance is financed by payroll taxes paid by employees, employers and self-employed people, along with other sources. Medicare doctor and drug benefits are financed through funds authorized by Congress, beneficiary premiums and other sources. Whether an insurer or a public program pays, the money traces back to premiums, payroll taxes and other public funds. Changing the payer changes the route the money takes; whether the total rises or falls is a separate question.

The Commonwealth Fund’s US profile identifies relatively limited direct drug-price regulation and complex rebate arrangements as contributors to high pharmaceutical spending. Studies show that when physicians consolidate with hospital systems, spending and prices can increase and care quality may be the same or lower, the Government Accountability Office found; the effect on access to care is unclear. That evidence does not mean every merger has the same effect, but it challenges the assumption that combining providers automatically improves value.

In testimony on May 12, 2022, Congressional Budget Office (CBO) Director Phillip Swagel described five illustrative options for a Medicare-based single-payer system, in which a single public or quasi-public plan pays for care. Across those options, CBO projected that federal health subsidies in 2030 would increase by $1.5 trillion to $3 trillion, while national spending would range from $0.7 trillion lower to $0.3 trillion higher than under the then-current law. This historical comparison illustrates how costs can move to the federal budget without rising by the same amount for the country. It is not a current forecast for a new bill.

Quality is more than spending or new technology

The OECD’s Health at a Glance 2025 reports that US mammography screening in 2023 was among the highest, alongside Denmark, Sweden and Finland, at 80 percent or more among women ages 50 to 69. The Commonwealth Fund’s US profile also reports lower life expectancy and higher avoidable death rates than peer countries. A health system can have strengths in particular services while performing poorly on broader outcomes.

The OECD identifies differences in smoking, alcohol use and obesity, as well as income, education and living environments, as influences on cross-country health outcomes. Life expectancy is consequently an important result to examine, but it is not a report card on medical treatment alone.

How government can change the tradeoffs

Two existing Medicare policies show different approaches: one changes how providers work together, and the other changes what the program pays for selected drugs.

Under Medicare’s Shared Savings Program, groups of doctors, hospitals and other providers called accountable care organizations, or ACOs, coordinate care and try to avoid unnecessary services and medical errors. An ACO that both delivers high-quality care and spends health care dollars more wisely may be eligible to share in the savings it achieves for Medicare. For performance year 2024, the most recently reconciled year reported by CMS, ACOs earned $4.1 billion in shared savings and saved Medicare $2.5 billion. The provider payments and Medicare savings are separate reported results, not two labels for the same amount.

Medicare’s first negotiated prices for 10 selected drugs became effective on January 1, 2026. CMS estimated that had those prices been in effect during 2023, they would have saved $6 billion in net covered prescription-drug costs, or 22 percent, after rebates and certain fees and payments. That is an estimate using an earlier year, not a tally of money already saved in 2026.

The Emergency Medical Treatment and Labor Act requires Medicare-participating hospitals offering emergency services to screen for emergency conditions and provide stabilizing treatment or an appropriate transfer, regardless of ability to pay. This protects emergency access, but its purpose and reach differ from comprehensive insurance.

Universal coverage and the choices ahead

Universal coverage describes who is covered; single payer describes an arrangement for financing that coverage. Swagel’s 2022 testimony described single payer as one of various ways to achieve near-universal coverage. For comparison, Germany’s compulsory insurance system uses nongovernmental sickness funds, health-insurance organizations that pay for covered care, financed through wage contributions shared by employers and employees.

Physicians for a National Health Program, an organization advocating single-payer reform, proposes a public or quasi-public plan covering medically necessary care while delivery remains largely private. Its proposal would eliminate premiums, copayments and deductibles and make coverage portable rather than tied to employment or a provider network. In that design, a public insurer does not require the government to own the hospitals or employ every doctor.

The organization argues that a single payer would reduce the complex billing and cost-tracking work retained when providers deal with multiple payers. It proposes taxes based on ability to pay, negotiated drug and supply prices, and annual hospital budgets instead of billing for each service or item. It also acknowledges that shrinking administration would require job-transition support and retraining for affected workers. The organization points to traditional Medicare as an existing US example of public insurance, while acknowledging its high cost sharing and gaps in coverage. Pointing to an existing public program does not establish that every proposed benefit expansion would finance itself.

In an October 2025 paper, Tax Foundation economists Will McBride and Alex Durante said fully eliminating the employer insurance tax exclusion would mean a major tax increase for workers and described a cap as a more incremental reform. That approach seeks to limit the incentive for especially expensive employer plans while preserving more of the existing tax benefit.

In Senate testimony on May 19, 2021, Michael F. Cannon, the Cato Institute’s director of health policy studies, argued that government interventions inhibit entry, cost consciousness and competition. He proposed giving consumers more control over health dollars, including through expanded health savings accounts, so they would benefit personally from lower prices and demand price competition. A health savings account holds tax-exempt funds to pay or reimburse certain medical expenses, with eligibility requirements for contributions. He also urged repeal of certificate-of-need laws, which he argued protect existing providers from competition, and changes to clinician licensing that would allow new forms of care delivery. Certificate-of-need laws require state approval for new health facilities or specified expansions of services, with the stated aim of controlling duplication and costs. Cannon cited a California experiment in which cost-conscious consumers prompted high-cost hospitals to reduce hip and knee replacement prices by 37 percent over two years. His example concerns particular procedures and a specific payment design, not proof that expanding savings accounts would reproduce the same result throughout health care.

Cannon further argued that rules limiting what insurers can charge, intended to protect patients with preexisting conditions, do not end discrimination but shift it into the design of plan benefits. That is his criticism of the protections, not proof that removing them would guarantee affordable care to someone with expensive needs.

In CBO’s modeled single-payer options, people would use more care, but demand would rise more than supply, leaving more unmet demand in the form of delays and forgone care. Broader insurance and lower patient bills do not make provider capacity unlimited. Conversely, provider competition has less practical meaning where a patient cannot afford the bill or reach an alternative.

Coverage decisions underway

The budget reconciliation law enacted on July 4, 2025, commonly known as the One Big Beautiful Bill Act (Public Law 119-21), changed Medicaid and other health programs. Beginning January 1, 2027, the law requires states to make Medicaid eligibility for certain adults depend on community engagement, unless a state opts to start sooner. CMS also calls it a work requirement.

The rule covers nonpregnant adults ages 19 to 64 who are not entitled to or enrolled in Medicare and are in the Medicaid adult group or certain demonstration programs providing health coverage. Affected adults can meet the requirement through 80 hours per month of work, community service or qualifying work programs, half-time education, combined activities, or monthly income of at least the federal minimum wage multiplied by 80 hours.

CMS lists exclusions including pregnancy and postpartum coverage, certain caregivers for children under 14 or people with disabilities, and medical frailty or special medical needs that significantly impair the ability to comply. Having a medical condition does not, by itself, guarantee that the implementing rules exclude someone.

Massachusetts, other states and the District of Columbia, joined by the governors of Kentucky and Pennsylvania, have sued Mehmet Oz, who leads CMS, in federal court. The court’s order in the case, Commonwealth of Massachusetts v. Oz, names three points at issue: the definition of “medically frail,” a 12-month look-back period for assessing claims of medical frailty, and a work requirement on the short-term hardship exception.

Judge Richard G. Stearns denied the states’ request for a preliminary injunction, an order they sought before the case is decided, on July 29, 2026. The July 29, 2026 denial was without prejudice and did not pause implementation of the community-engagement requirement, which begins January 1, 2027, unless a state opts to start sooner for applicable individuals. His analysis began and ended with one factor, irreparable harm, rather than deciding the merits, meaning whether the states’ challenge should succeed. The states had argued that the staff time and money needed to comply with CMS’s change in rules could not be recovered.

Summary judgment is a decision without trial when the undisputed facts entitle one party to judgment as a matter of law. The plaintiffs filed a response on summary judgment on September 28, 2026. The court’s schedule, entered on August 6, 2026, set a hearing for October 20, 2026.

The premium tax credit generally applies to incomes from 100 to 400 percent of the federal poverty line, subject to other eligibility rules. The federal poverty line is an annual dollar income guideline based on family size. Congress removed that upper limit temporarily, for tax years 2021 through 2025, the IRS says. The IRS describes the expansion only for those years, so a household with income above the limit should not assume it still qualifies and should check before choosing a plan. For 2026 coverage, the enhanced premium tax credits ended after 2025; the IRS says households with income above 400 percent of the federal poverty line are not eligible for the premium tax credit, subject to the other eligibility rules.

A HealthCare.gov application can identify eligibility for Marketplace savings or Medicaid and the Children’s Health Insurance Program, and eligible applicants can compare plans and enroll. Use the official application and plan information to check eligibility, covered providers and personal costs.

When a reform promises savings, ask whose bill falls and where the remaining cost goes. When it promises access, ask whether needed providers and services are available.
