Insurance is the purest form of the cost transfer system. It does not "manage risk." It prices risk, manufactures denial, and delays payment — systematically transferring cost to those least able to litigate. The arithmetic foundation of this system is collapsing: administrative costs exceed the medical costs themselves, denial rates reach 19%, and the appeal rate is only 0.2%.
This is not a "market outcome." This is institutional design.
The first principle of insurance is risk pooling: many people collectively bear the losses of a few. But the business model of for-profit insurance is completely different: revenue comes from premiums; profit comes from the difference between premium income and medical expenditure. This means every denial, every delay, directly converts into profit.
The US Senate Finance Committee Democrats' investigation reveals this logic: "When for-profit insurers use administrative tools such as prior authorization and claim denials to create barriers to care, they are also generating revenue and profit by retaining control of premium dollars not used to pay medical claims, even if only temporarily." This creates an incentive for profit-driven insurers to impose administrative barriers on patients and providers — even when this may endanger patient care and lead to worse health outcomes — in order to retain premium dollars for as long as possible.
In 2024, among ACA marketplace plans sold on HealthCare.gov, insurers denied 19% of in-network claims. In 2023, in-network denial rates ranged from 1% to 54%, varying by insurer and state.
But what truly reveals the nature of the system is the appeal data: fewer than 1% of denied claims were appealed, and of those appealed, 56% of insurers upheld the original decision. In other words: the vast majority of denials are never challenged, because patients do not know how to appeal, or cannot afford to appeal.
US Senate Finance Committee data shows that insurers retain "administrative costs and profits" of nearly USD 1,000 per enrollee per year, while rules designed to recover this money return only about USD 200.
Denial is only the first layer. The second layer is delayed payment.
The US spends over USD 370 billion annually on healthcare administrative costs, nearly 10% of total spending — and research shows that more than half of that is wasted. Administrative costs have more than tripled since 2020, processing over 9 billion medical claims annually, at an average administrative cost of USD 12–19 per claim.
Hospitals reported spending over USD 25 billion on claims adjudication in 2025, with an estimated USD 18 billion of that being avoidable administrative work to overturn improper denials.
The American Medical Association's survey shows doctors and staff spend an average of 13 hours per week completing prior authorization requests, with 40% of doctors having staff dedicated exclusively to prior authorization. And ultimately, 96% to 98.5% of prior authorization requests are eventually approved — meaning the entire process is almost entirely administrative waste.
Prior authorization was once used only for extremely expensive interventions. Now even the simplest generic drugs require it.
The AMA survey found:
- 82% of doctors say prior authorization always or often delays patients' access to necessary care
- Nearly 30% of doctors report that prior authorization has led to serious adverse events for patients, including 8% reporting disability, permanent physical impairment, or death
- 61% of doctors fear that unregulated use of AI tools by payers will increase prior authorization denials
UnitedHealth Group's AI tool nH Predict was found by a Senate investigation to have pushed post-acute care denial rates from 8.7% to 22.7% within three years.
UnitedHealth Group reported USD 447.6 billion in revenue and USD 12.05 billion in profit in 2025 — the most profitable payer in the industry. Its operating margin was 4.2%, leading Cigna's 3.2%.
The source of these profits is not "better risk management." It is systematic denial and delay.
UnitedHealth Group spent USD 11.7 million on federal lobbying in 2025, up 71% year-over-year. America's Health Insurance Plans (AHIP) spent USD 5.3 million on lobbying in Q1 2026, a quarterly record. The entire insurance industry spent USD 173 million on federal lobbying in 2025.
Insurance is only half the cost transfer system. The other half is the financialization of healthcare providers.
Private equity has invested over USD 1 trillion in US healthcare over the past decade. These funds convert hospitals, nursing homes, and physician practices into financial products through leveraged buyouts, profit maximization, and sale of real estate assets.
Real Estate Investment Trusts (REITs) buy hospital real estate through sale-leaseback transactions, then lease it back on long-term contracts. These are typically triple-net leases, transferring the burden of taxes, insurance, and maintenance to the hospital tenant.
BMJ research found that hospitals acquired by REITs saw total fixed assets decrease by 31.0% and building assets decrease by 40.8%, while their risk of closure or bankruptcy was more than five times higher — 25.3% of REIT-acquired hospitals closed or filed for bankruptcy, compared to only 4.3% in the control group.
Steward Health Care is the typical case: private equity firm Cerberus sold its hospital real estate to a REIT, then leased it back. When the REIT raised rents, Steward could not pay, filing for bankruptcy in May 2024 — and two hospitals in Massachusetts closed within a year.
| Dimension | Pharmaceuticals | Healthcare | Insurance |
|---|---|---|---|
| Revenue driver | Lifelong medication | Volume of tests, procedures | Premium income minus medical payout |
| Structural incentive | Prefer chronic | Prefer more | Prefer to pay less |
| Cost transfer mechanism | Patent monopoly | Fee-for-service | Denial, delay |
| Evidence manipulation | Ghostwriting | Surrogate endpoints | AI batch denials |
| Financialization | REITs, private equity | Hospital chains | Insurer stock buybacks |
| Structural output | 400,000 deaths | 30% spending unnecessary | 19% denial rate |
These are not three systems. This is one system, with three faces.
"Costs must not be transferred to the voiceless vulnerable."
The cost transfer chain of the insurance system:
- Patients: pay premiums first, then are denied, then pay out of pocket — paying three times.
- Doctors and hospitals: forced to spend tens of billions of dollars overturning improper denials, costs ultimately passed to patients.
- Taxpayers: fund Medicare and Medicaid, while paying for the administrative waste of for-profit insurers.
- Future generations: inherit the debt of today's healthcare spending.
This is not a "market outcome." This is institutional design.
The Structural Diagnosis
Suffering is not a "side effect." Suffering is the product itself.
The machine must end. Not because of moral awakening, but because of arithmetic constraints. The US spends over USD 370 billion on healthcare administrative costs, more than half of which is wasted. The system's operating cost has exceeded its return.
The end is not "fixing" it. The end is replacing the incentive structure that produces it: from "the more you deny, the more you profit" to "the more you deliver care, the more you are rewarded."
