Public vs. Private Insurance
The U.S. runs four parallel insurance systems side by side — the VA for veterans, Medicare for seniors and the disabled, Medicaid for low-income Americans, and private insurance for most working-age people. They differ in who pays, how they're run, and — most importantly — what outcomes they produce. Where comparable data exists, here's how they stack up.
VA (Veterans Health)
- Who it covers
- Veterans who qualify by service & priority group
- Model
- Integrated, government-run system; salaried providers
- Often outperforms private care on quality & satisfaction
Medicare
- Who it covers
- Adults 65+, some disabled, end-stage renal disease
- Model
- Federal insurance; fee-for-service (Parts A/B) + private Advantage (Part C)
- Low admin overhead; high satisfaction
Medicaid
- Who it covers
- Low-income adults, children, disabled, some elderly
- Model
- State + federal; state-run with federal matching funds
- Improves access & financial security; outcomes vary by state
Private Insurance
- Who it covers
- Employer-sponsored & marketplace enrollees
- Model
- Insurer-managed; premiums, networks, deductibles
- Highest admin cost; broadest provider choice
Satisfaction & overhead compared
Two measures where public coverage consistently outperforms private: patients rate public programs more highly, and public programs spend far less on administration.
Patient satisfaction
% rating overall care 8–10 (CAHPS-style surveys)
Administrative overhead
% of spending consumed by administration (lower is better)

| Metric | VA | Medicare | Medicaid | Private | Note |
|---|---|---|---|---|---|
| Patient satisfaction (% 8–10) | 87% | 82% | 78% | 76% | CAHPS overall rating |
| Admin overhead (% of spending) | ~3% | ~2% | ~5% | ~13% | Lower = more dollars reach care |
| Quality composite (relative) | High | High | Moderate | Moderate | VA often matches or beats private (JAMA, RAND) |

| Preventable hospitalizations | Low | Moderate | Moderate–High | Moderate | Access & continuity drive this |
| Amenable mortality (lower better) | Low | Low–Moderate | — | Moderate | Deaths preventable with timely care |
Key findings
Public programs lead on value
Medicare and the VA spend a far smaller share on administration than private insurers, so more of each dollar reaches actual care.
VA tops satisfaction & quality
Despite misconceptions, the VA consistently matches or outperforms private insurance on patient satisfaction and on clinical quality measures for chronic disease, cancer screening, and preventive care.
Medicaid improves access, outcomes vary
The Oregon Health Insurance Experiment (RCT) found Medicaid increased utilization, reduced financial strain, and improved mental health; physical-health gains were mixed and vary by state implementation.
Private costs the most per dollar
Private insurance carries the highest overhead and profit margin, yet does not consistently deliver better outcomes than public coverage — a core driver of the U.S. affordability problem.
Methodology & sources
Satisfaction — Approximate share of enrollees rating overall care 8–10 on CAHPS-style surveys. Sources: VA Survey of Healthcare Experience of Patients (SHEP), CMS CAHPS for Medicare & Medicaid, KFF employer health survey.
Admin overhead — Share of spending consumed by administration. Sources: CMS Trustees Report (Medicare ~2%), MACPAC (Medicaid ~5%), CBO, and KFF/Woolhandler & Himmelstein analyses of private insurer overhead (~12–17% including profit). VA overhead is low due to its integrated, salaried-provider model.
Quality composite — Relative ranking based on peer-reviewed comparisons (e.g., JAMA, Annals of Internal Medicine, RAND) finding the VA meets or exceeds private-sector benchmarks on chronic-disease management, cancer screening, and preventive care.
Medicaid outcomes — Drawn from the Oregon Health Insurance Experiment (a rare RCT) and ACA expansion studies: increased utilization, reduced financial strain, improved mental health; physical-health gains mixed and state-dependent.
