Who Pays, Who Delivers, Who Regulates, Who Supplies: A Functional Map of American Health Care and the Connections Between Its Parts

Why a Map and Not a List

Most descriptions of the U.S. health care system start with a list: hospitals, physicians, insurers, government programs, drug companies. A list is accurate but does not explain how the system works, because what matters is how the pieces connect. A patient's single office visit touches an insurer, a clinic, a licensing board, an accrediting body and a supplier of tests and drugs, often without the patient seeing any of them. This paper groups the parts of the system by function into four groups, describes each briefly and then gives most of its pages to the links between them, because those connections are what newcomers usually describe wrong. The four groups follow the approach of our textbook, which treats financing, delivery and regulation as interlocking subsystems (Shi & Singh, 2022).

The Four Groups

Financing: who pays. Money enters the system from employers and employees through private insurance premiums, from taxpayers through Medicare, Medicaid and other public programs, and from patients directly through deductibles, copayments and bills they pay themselves. National health spending reached about $4.5 trillion in 2022, and private insurance, Medicare and Medicaid together paid the largest shares of it (Martin et al., 2024).

Delivery: who provides care. Care is delivered by a wide range of organizations: acute care hospitals, group and solo medical practices, federally funded health centers, nursing homes, agencies that send nurses and aides into the home, retail and hospital pharmacies, and many more. Most delivery organizations in the United States are privately owned, either nonprofit or for-profit, while some, such as Veterans Affairs hospitals and county hospitals, are government owned.

Regulation: who sets and enforces the rules. Federal agencies such as the Centers for Medicare & Medicaid Services attach conditions to Medicare and Medicaid payment that every participating provider has to satisfy. States license health professionals and facilities. Private accrediting organizations, such as The Joint Commission, survey hospitals against standards, and accreditation can be used to show that a hospital meets federal conditions.

Supply: who sells into the system. Pharmaceutical companies, device manufacturers, distributors and technology vendors sell products that delivery organizations use and that payers often pay for.

The four groups are not separate worlds. The same organization can sit in more than one: a large insurer may own physician practices, a hospital system may run its own health plan, and the federal government both pays for care through Medicare and delivers it directly through Veterans Affairs hospitals. These overlaps are part of why the connections described next matter so much. When one organization pays for care and also delivers it, the usual tension between payer and provider over price and volume moves inside a single company, and decisions that would otherwise be negotiated in public become internal choices that patients and regulators rarely see.

The Connections

Financing to delivery: payment shapes what is delivered. Payers do not simply pay bills; the way they pay changes what providers do. When a payer pays a fixed amount per hospital admission, a hospital earns more by shortening stays. When a payer pays for each service, a practice earns more by providing more services. Students often describe insurers as passive check writers, but payment methods are one of the strongest forces in the system.

Regulation to delivery: rules attached to money. Much federal regulation of hospitals works through payment. A hospital that wants Medicare patients must meet Medicare's Conditions of Participation. This is why a federal agency that does not own or license a single hospital still shapes how almost every hospital operates.

Regulation to regulation: public and private overlap. The connection between a private accreditor and a federal agency surprises most newcomers. Accreditation by an approved organization can be accepted as evidence that a hospital meets federal conditions, so a private organization's survey effectively does a public job.

Supply to financing: prices flow through to premiums. When drug or device prices rise, insurers pay more, and those costs return to employers and employees as higher premiums and to taxpayers through public programs. Patients see this connection only at the pharmacy counter.

Delivery to financing: providers negotiate. Large hospital systems negotiate prices with private insurers, and the prices they win depend partly on their market power. The same procedure can be paid at very different prices depending on who is paying and who is providing it.

Patients and all four. Patients connect to every group, often at once. One visit can involve a premium paid months earlier, a copay at the desk, a licensed clinician, an accredited facility and a drug made by a supplier.

What the Map Explains

The map explains why changing one part of the system rarely stays in one part. A new payment rule changes how hospitals deliver care; a new drug changes premiums; an accreditation standard changes hospital staffing. It also explains why the system is so hard for patients to see. The connections that matter most, such as payment methods, negotiated prices and accreditation, happen out of their view.

The map has limits. It leaves out public health agencies, which protect whole populations rather than treat individuals, and it simplifies the many forms of insurance into one financing box. It also cannot show change over time. The system did not arrive at this shape by design; it grew through decades of decisions by professions, employers and governments (Starr, 1982). A map drawn fifty years ago would look different, and one drawn after the next major policy change will too. Still, a newcomer who understands these four groups and the connections between them can place almost any news story about health care into the system and ask the right first question: who pays, and how does that payment shape what happens next?

For a student entering health care administration, this question is a habit worth building. Most of the problems an administrator faces, from a staffing shortage to a denied claim, sit at one of the connections on this map rather than inside a single group, and solving them usually means working with people in another group who see the same problem from the other side.
