The Healthcare Org Chart Nobody Gave You
A Guide to How U.S. Healthcare Is Actually Organized
If you’ve ever tried to understand how American healthcare works, you’ve probably hit the same wall everyone hits: it’s not one system. It’s dozens of overlapping structures — corporate entities, clinical networks, payment models, facility types, and government programs — all tangled together in ways that don’t follow any clean logic.
A single health system might be a not-for-profit corporation that owns hospitals, employs 3,000 physicians, operates an insurance plan, runs federally funded community health centers, has joint-venture surgery centers with an orthopedic group, participates in three different Medicare payment experiments, and recently signed an affiliation agreement with the Mayo Clinic.
That’s not unusual. That’s normal.
This series breaks down the 30 organizational models that make up U.S. healthcare, organized across 9 categories. Each post answers four questions:
What is it? A clear definition with no jargon left unexplained.
Why does it exist? The specific problem it was created to solve.
How is it organized? Where it sits relative to everything else — who owns it, who it reports to, who it contracts with.
What are the tradeoffs? Every model has strengths and weaknesses. There are no perfect structures.
The 9 Categories
Part 1: Independent Providers & Practice Models — From the solo family doctor running their own show to the 500-physician multi-specialty group. Where most physicians actually work.
Part 2: Integration & Network Models — The structures that connect independent providers into something bigger: CINs, IDNs, IPAs, PHOs, MSOs, and franchise models. This is where the alphabet soup lives.
Part 3: Hospital & Facility Types — Not all hospitals are the same. Academic medical centers, community hospitals, rural critical access hospitals, safety-net hospitals, FQHCs, specialty hospitals, and physician-owned hospitals each exist for different reasons and operate under different rules.
Part 4: Post-Acute Care — What happens after the hospital. Skilled nursing facilities, home health agencies, hospice organizations, and long-term acute care hospitals. This is where most healthcare dollars are won or lost under value-based care.
Part 5: Behavioral Health — Community mental health centers, psychiatric hospitals, and substance use disorder treatment facilities. A parallel system that’s chronically underfunded and increasingly critical.
Part 6: Ambulatory & Outpatient — Surgery centers, urgent care clinics, and retail clinics. Where care is migrating away from the hospital.
Part 7: Value-Based & Risk Structures — ACOs, Medicare Advantage, Medicaid managed care, risk-bearing provider organizations, and bundled payments. The payment models layered on top of everything else.
Part 8: Government Delivery Systems — The VA, military health system, and Indian Health Service. Three massive systems that operate parallel to civilian healthcare.
Part 9: Emerging & Non-Traditional Models — Payer-provider convergence (Optum, CVS Health), direct primary care, concierge medicine, virtual-first care, and employer clinics. The new entrants reshaping the landscape.
Part 10: The Map — How all 30 models layer together. The capstone that ties the full series into a single framework.
Who This Is For
If you work in healthcare and need to explain your industry to a board member, an investor, a new hire, or a partner from another sector — this series gives you the language.
If you’re entering healthcare from tech, finance, or consulting — this is the orientation nobody provided.
If you build products for healthcare — this is why your platform needs to flex across organizational boundaries.
