Part 8: The Government Systems Most People Forget
VA, Military Health, and Indian Health Service
When people talk about U.S. healthcare, they almost always mean the civilian system — private insurance, employer benefits, Medicare, Medicaid. But three massive government systems operate in parallel, serving roughly 25 million people combined.
These aren’t insurance programs. They’re direct delivery systems — the government owns the facilities, employs the providers, and delivers the care.
Veterans Health Administration (VA) — The largest integrated delivery system in the United States. 171 medical centers, over 1,100 outpatient sites, approximately 9 million enrolled veterans. The VA employs its own doctors, runs its own hospitals, and operates its own EHR (they pioneered electronic health records with VistA in the 1980s, decades before the private sector caught up). It has unmatched expertise in PTSD, traumatic brain injury, polytrauma, and veteran-specific conditions.
Military Health System (DoD/TRICARE) — Healthcare for active-duty service members, their families, and military retirees — about 9.6 million beneficiaries. Hospitals and clinics on military bases provide direct care. TRICARE insurance fills in the gaps with civilian provider networks. The system’s primary mission isn’t just healthcare — it’s maintaining medical readiness for military operations.
Indian Health Service (IHS) and Tribal Health Programs — The most underfunded of the three. About 2.6 million American Indians and Alaska Natives receive healthcare through IHS-operated facilities, tribally operated programs, or urban Indian health organizations. The federal government has a treaty and trust obligation to provide this care. Per-capita IHS spending is a fraction of what the VA or Medicare spends. Health disparities are profound — life expectancy 5.5 years lower than the national average.
Why They Matter
These three systems are often invisible in mainstream healthcare conversations. But they represent fundamentally different models of care delivery — government-owned, government-operated, and government-funded — that test assumptions about integration, access, and efficiency in ways the private sector can’t.
The VA’s Nuka System of Care partnership with Alaska’s Southcentral Foundation is arguably the most patient-centered care model in the world. IHS tribal programs under self-determination are some of the most culturally competent. DoD’s unified command structure enables coordination that private systems envy. The lessons from these systems are underappreciated.
