I’ve spent the last several months mapping how U.S. healthcare is actually organized. Thirty models across five layers, from the solo family physician to the $370 billion vertical empire of UnitedHealth Group.

The throughline I didn’t fully see until I was done: every organizational model in American healthcare was created to solve a coordination failure. And every one of them, in solving it, created a new boundary that produced a different coordination failure.

Physicians couldn’t negotiate alone, so they formed IPAs. The IPA solved the negotiating problem and created a data fragmentation problem. Hospitals and physicians needed unified managed-care contracts, so they built PHOs. The PHO solved the contracting problem but didn’t produce real clinical integration. Independent providers needed value-based contracts without merging, so they invented the CIN. The CIN solved the participation problem but created a governance problem.

Every solution works. Every solution leaves a gap. That gap creates the next model. It’s been running for forty years.

So where does this end? I see three possible futures. All three are already underway.

Future 1: Convergence Through Ownership

Optum employs or affiliates with roughly 90,000 physicians. CVS Health owns Aetna, Oak Street Health, Signify Health, MinuteClinic, and Caremark. Humana owns CenterWell clinics, home health, and pharmacy.

Let me be direct about this one: what these companies are doing is not integration. It’s annexation. They’re buying the pieces of the healthcare value chain one acquisition at a time and calling it coordination.

Inside the walls, it works. An Optum physician referring to an Optum specialist, with the patient insured by UnitedHealthcare, creates seamless coordination. Data flows. Incentives align.

But the math breaks at the edges. Even Optum, with 90,000 physicians, covers roughly 9% of the practicing workforce. The U.S. has over a million doctors. The solo family physician in rural Ohio isn’t getting acquired. The critical access hospital that’s the only facility for 50 miles isn’t joining Optum’s network. Vertical integration solves coordination for the patients inside the fortress and leaves everyone else with the same fragmentation they’ve always had.

And there’s a regulatory ceiling that’s getting lower every year. The FTC sued US Anesthesia Partners. The DOJ is blocking hospital mergers. State AGs are investigating PE-backed rollups. There is a political limit to how much healthcare a handful of corporations can own.

I respect the operational ambition. I don’t think it scales to a country of 330 million people.

Future 2: Federated Networks With Shared Risk

CINs, ACOs, and the enablement platforms that support independent physicians represent a more democratic alternative. Don’t merge. Align. Share data, follow common protocols, split the savings.

About 480 MSSP ACOs now cover 11 million Medicare beneficiaries. Clinically integrated networks let independent physicians participate in value-based contracts while keeping their practices. Enablement platforms provide the analytics and care management that small practices can’t build alone.

I have more sympathy for this future than the first one. It preserves physician independence. It doesn’t require massive capital. It works with existing structures.

But I’ve watched enough federated networks up close to know their failure mode. The physician champion who drove CIN participation retires and nobody replaces the energy. The health system anchor gets a new CEO who decides employed physician growth matters more than network maintenance. The shared savings pool has one bad year and three practices quietly disengage. I’ve seen a thriving CIN hollow out in 18 months after a single leadership change.

Federated networks are elegant when they work. They’re fragile by design, because they depend on sustained voluntary commitment from parties with different economics and different priorities.

Future 3: Platform-Mediated Coordination

This future doesn’t have a single company building it yet. It’s an architectural pattern emerging at the intersection of foundation models, ambient computing, and healthcare’s slow progress on interoperability.

The theory: if no entity can see the full patient picture across all 30 organizational models, the solution isn’t a bigger entity or a better network. It’s an intelligence layer that sits between the patient and the system. One that persists across care transitions, synthesizes data from multiple sources, and acts on behalf of the patient regardless of which organizational model they’re inside at any given moment.

Not an entity. Not a network. A layer.

It doesn’t require ownership, formal agreements, or physicians giving up independence. It works with the existing stack. And the technology to build it became viable at a useful quality level approximately 18 months ago.

The counterargument is earned: healthcare is littered with the corpses of technology platforms that were going to fix coordination. Google Health. Microsoft HealthVault. Haven. The pattern is consistent: technology overlaid on the system without changing incentives is a dashboard nobody uses.

This might be different. Or it might be Google Health with better language models. I’ll make the case for why I think it’s different, but I owe the graveyard its respect.

Where I Stand

I don’t think Future 1 gets us there. It concentrates power without reaching the majority of patients and providers who will never be inside a conglomerate’s walls.

I don’t think Future 2 gets us there alone. It’s the right instinct — align without owning — but the governance overhead and fragility are real constraints, not solvable objections.

Future 3 is the only architecture I see that scales without consolidation, works for independent providers, and puts the patient at the center. But it only works if it’s built on a payment model that rewards health over volume. The intelligence layer without value-based economics is an app. Value-based economics without the intelligence layer is a spreadsheet.

The endgame isn’t one of these futures. It’s the interaction between them.

But if the answer involves a platform, the immediate question is: why haven’t the entities that already exist just built one?

You’ve now read about 30 distinct organizational models across 9 categories. If your head is spinning, that’s normal. American healthcare’s organizational complexity is not a bug — it’s the natural result of a system that evolved incrementally over 100 years, with each new model created to solve a specific problem without replacing the ones that came before.

Here’s how to think about it all.

Layer 1: The Base — Where Physicians Practice

At the bottom are the practice models: solo practitioners, small groups, large single-specialty groups, multi-specialty groups, and faculty practice plans. This is where physicians actually see patients. Everything else is built on top of this layer.

Bottomline: About 50% of U.S. physicians still work in practices of 10 or fewer doctors. The base of American healthcare is smaller and more fragmented than most people realize.

Layer 2: The Connective Tissue — Networks and Integration

Above the practice layer sit the structures that connect independent providers into coordinated entities: CINs, IDNs, IPAs, PHOs, MSOs, and franchise/affiliation models. These exist because individual practices lack the scale, data, and infrastructure to participate in modern healthcare delivery and payment.

Bottomline: The spectrum from independence (IPA) to full integration (IDN) represents a fundamental tradeoff between autonomy and coordination. Most of American healthcare sits in the messy middle.

Layer 3: The Facilities — Where Care Happens

The physical infrastructure: AMCs, community hospitals, CAHs, safety-net hospitals, FQHCs, specialty hospitals, and physician-owned hospitals on the inpatient side. ASCs, urgent care clinics, and retail clinics on the outpatient side. SNFs, home health agencies, hospice organizations, and LTACHs on the post-acute side. CMHCs/CCBHCs, psychiatric facilities, and SUD treatment facilities for behavioral health.

Bottomline: Care is migrating from higher-cost to lower-cost settings — from hospital to ASC, from SNF to home health, from ER to urgent care. This migration is the dominant structural trend in healthcare delivery.

Layer 4: The Payment Models — Who Bears Risk

Layered on top of all the delivery infrastructure are the payment and risk structures: ACOs, ACO REACH, Medicare Advantage, Medicaid MCOs, risk-bearing provider organizations, and bundled payment programs. These don’t replace the delivery structures — they sit on top of them, reshaping incentives.

Bottomline: Payment models are the most powerful force reshaping healthcare organization. When you change how money flows, you change how care is delivered. Every organizational innovation in the past 15 years has been driven by the shift from fee-for-service to value-based care.

Layer 5: The New Entrants — Disrupting from Outside

Payer-provider convergence entities (Optum, CVS Health), DPC, concierge medicine, virtual-first primary care, and employer clinics represent models that route around the existing system’s limitations rather than working within them.

Bottomline: The most disruptive entrants are the vertical integrators — UnitedHealth/Optum, CVS/Aetna — who are assembling the full value chain under one corporate roof. They’re not playing within the existing structure. They’re building a parallel one.

The Government Parallel

Running alongside all of this are three massive government delivery systems — the VA, the Military Health System, and the Indian Health Service — that operate under completely different rules, funding mechanisms, and governance structures.

Why It Matters

The practical implication of all this complexity is that no single product, policy, or partnership strategy works across the entire healthcare system. A technology platform designed for an IDN won’t fit a solo practice. A payment model that works in California’s delegated market won’t work in a state where IPAs don’t exist. A care delivery innovation from an AMC won’t translate to a CAH.

Understanding which organizational model you’re dealing with — and which layer of the stack you’re operating in — is the prerequisite for doing anything effective in healthcare.

That’s the map. Use it well.

The physician still bills insurance for all clinical services. The retainer pays for the enhanced access and wellness services that insurance doesn’t cover.

What It Is

A concierge practice charges patients an annual retainer for premium access — but unlike DPC, it still bills insurance for clinical care. The retainer subsidizes small panels and extended services; insurance pays for the medicine.

Why It Exists

Affluent patients want guaranteed access, unhurried appointments, and a physician who knows them deeply. Physicians want smaller panels and better economics without giving up insurance revenue. Concierge medicine serves both.

The Tradeoffs

The upside: Exceptional access. Dual revenue streams (retainer + insurance). Reduced burnout for physicians. Patients love the experience.

The downside: Creates a two-tier system. When a physician converts to concierge, 1,500 patients lose their doctor so that 500 can have a premium experience. Retainer fees are not HSA-eligible. Limited to affluent markets.

The Bottom Line

Concierge medicine works for the people who can afford it. The ethical question — should access to your doctor depend on your ability to pay a retainer? — has no clean answer. But the model’s persistence and growth suggest there’s strong demand from both patients and physicians.

What It Is

About 1,800 DPC practices charge a flat monthly membership ($50–$150) for unlimited primary care. No insurance billing. No coding. No prior authorizations. Typically 400–800 patients per physician versus 2,000+ in traditional practice.

Why It Exists

Insurance-based primary care has become unsustainable for many physicians. Twenty-minute visit slots. 2,000+ patient panels. Hours of documentation for every hour of patient care. DPC strips all of that away and rebuilds the physician-patient relationship from scratch.

The Tradeoffs

The upside: Zero admin burden. Small panels. Longer visits. Transparent pricing. Physician autonomy. Evidence suggests DPC reduces total cost of care by keeping patients out of ERs and specialist offices.

The downside: Inaccessible to low-income patients. Doesn’t cover hospitals, specialists, or emergencies (patients need separate catastrophic coverage). Exists entirely outside the insurance system — no population health reporting, no quality measurement infrastructure. Inherently small-scale.

The Bottom Line

DPC is the purest expression of primary care idealism in American medicine. It proves that when you remove insurance overhead, primary care can work beautifully. The question is whether a model that serves 600 patients per doctor can address a country with 330 million people who need primary care.

Nuka exists because an Alaska Native tribal organization took control of its healthcare from the federal government and rebuilt it from scratch.

What It Is

The IHS is a federal agency providing healthcare to approximately 2.6 million American Indians and Alaska Natives through IHS-operated facilities, tribally operated programs (under Self-Determination contracts), and urban Indian health organizations.

Why It Exists

The federal government has a trust responsibility and treaty obligation to provide healthcare to federally recognized tribal nations. AI/AN populations face extreme health disparities — life expectancy 5.5 years lower than the national average — often in remote areas with no private healthcare infrastructure.

The Tradeoffs

The upside: Tribal self-determination empowers local control and cultural competence. The Nuka model is globally recognized. Community-based approach addresses social determinants in context.

The downside: Chronically and severely underfunded — IHS per capita spending is a fraction of other federal programs. Recruitment in remote locations is extremely difficult. Annual Congressional appropriations (not an entitlement) create funding uncertainty.

The Bottom Line

IHS is simultaneously the most underfunded federal healthcare system and the source of some of the most innovative delivery models in the world. The Nuka System of Care proves what’s possible when tribal communities have control, funding, and the freedom to redesign care from the patient outward.

These are not healthcare companies that offer insurance. They’re conglomerates that control the full value chain — from the premium dollar to the exam room to the pharmacy counter.

What It Is

A payer-provider convergence entity is an organization where a health insurer has acquired or built a provider delivery system, creating vertical integration across insurance and care delivery.

Why It Exists

When you control both the insurance premium and the care delivery, you eliminate the adversarial friction between payer and provider. You can direct patients to your own lower-cost sites of care. You combine claims data with clinical data. You capture margin at every step.

The Tradeoffs

The upside: Aligned incentives. Data advantage. Full value chain economics. Nearly impossible competitive moat.

The downside: When the company paying for care also delivers care, the conflict of interest is structural. Market power concerns are significant. FTC scrutiny is increasing. Organizational complexity is enormous.

The Bottom Line

Payer-provider convergence is the most powerful structural force reshaping American healthcare right now. If you work in healthcare and you’re not thinking about how Optum, CVS Health, and Humana are vertically integrating, you’re not seeing the board clearly.

What It Is

The VA is a direct-care, government-owned-and-operated delivery system. It’s the healthcare arm of the Department of Veterans Affairs, funded through Congressional appropriations, not insurance billing.

Why It Exists

The federal government has a legal and moral obligation to provide healthcare to military veterans. The private sector was never designed to serve the unique clinical needs of veterans: polytrauma, PTSD, traumatic brain injury, Agent Orange exposure, Gulf War illness, military sexual trauma, and veteran homelessness.

The Tradeoffs

The upside: Largest integrated delivery system in America. Unmatched expertise in veteran-specific conditions. Pioneered EHR and telehealth at national scale.

The downside: Access challenges (wait times, geography). Government bureaucracy. The Oracle Cerner EHR modernization has been plagued by delays, cost overruns, and patient safety concerns.

The Bottom Line

The VA is the proof of concept for integrated, government-run healthcare in America. Its successes (care coordination, research, population health) and failures (access delays, EHR modernization) offer lessons for everyone building large-scale delivery systems.

Under a bundled payment, the hospital receives one payment that covers the surgery and everything that happens in the 90 days after — including where the patient recovers and whether they end up back in the hospital.

What It Is

A CMS model where providers accept a single, prospectively set payment for an entire episode of care — typically a hospitalization plus 90 days of post-acute care.

Why It Exists

Fee-for-service reimburses each service independently with no coordination incentive. Bundled payments create accountability for the whole episode, particularly the post-acute period where the biggest cost variation exists.

The insight: two hospitals might charge similar amounts for a hip replacement surgery. But one discharges to home health (cost: $4,000) while the other discharges to a SNF (cost: $18,000). The bundled payment makes the hospital care about that difference.

The Tradeoffs

The upside: Creates accountability for the full episode. Incentivizes appropriate post-acute placement. Growing evidence of cost savings.

The downside: Providers bear risk for events outside their control. Requires sophisticated analytics. Post-acute partners resist utilization management that cuts their volume.

The Bottom Line

Bundled payments are the most intuitive value-based payment model: one price, one episode, one accountable entity. The biggest impact comes from post-acute optimization — getting patients to the right (lower-cost) recovery setting.

That’s a risk-bearing provider organization. It’s the endpoint of the value-based care spectrum.

What It Is

Any provider entity — medical group, IPA, health system — that accepts delegated financial risk from a payer. It receives capitation and manages total cost and quality for an assigned population.

Why It Exists

Payers delegate risk to providers because providers are closer to the point of care. When a medical group bears financial risk, it has direct incentive to eliminate waste, invest in prevention, coordinate care, and keep patients out of the ER and hospital.

The Tradeoffs

The upside: Maximum alignment of clinical and financial incentives. Provider controls utilization. Surplus from efficient management flows to the provider. Drives genuine care model innovation.

The downside: Financial risk — one bad flu season, one cluster of high-cost cancer cases, and the surplus evaporates. Requires actuarial, analytics, and care management sophistication. Creates incentive to undertreat.

The Bottom Line

Risk-bearing is not for the faint of heart or the under-capitalized. But it’s where the incentives are most aligned with keeping patients healthy. If you want to understand where healthcare is heading, study California’s delegated model — it’s been running this experiment for 30 years.

What It Is

A Medicaid MCO is a health plan that contracts with a state Medicaid agency to provide Medicaid benefits in exchange for a per-member, per-month capitated payment. Unlike MA (which CMS runs nationally), each state designs its own Medicaid managed care program.

Why It Exists

States adopted MCOs to make Medicaid budgets predictable (fixed monthly payments instead of open-ended fee-for-service), improve care coordination for medically complex populations, and leverage managed care tools for people with significant social determinant challenges.

The Tradeoffs

The upside: Budget predictability. Care coordination for complex populations. Can integrate physical health, behavioral health, and long-term services.

The downside: Capitation rates are often inadequate, squeezing provider reimbursement. Fifty different state programs mean fifty different rule sets. Prior authorization can impede access for vulnerable populations. Publicly traded MCOs extracting profit from Medicaid dollars is politically contentious.

The Bottom Line

Medicaid managed care is a $400+ billion market that doesn’t get the attention it deserves. If you’re building for healthcare’s most vulnerable populations, you need to understand how MCOs work, because they control the dollars and the networks.

What It Is

An MA organization is a health plan that receives a fixed monthly payment from CMS for each enrolled beneficiary and provides all Medicare Part A and B benefits. It bears full insurance risk. Many MA plans add supplemental benefits — dental, vision, hearing, gym memberships — to attract enrollment.

Why It Exists

Traditional Medicare is fee-for-service with no care coordination infrastructure. MA plans use managed care tools — provider networks, prior authorization, case management — to coordinate care and manage costs. The capitated payment model creates an incentive to keep people healthy.

When a health system owns its own MA plan (Kaiser, UPMC, Geisinger), it controls both the insurance premium and the delivery system. That’s maximum alignment.

The Tradeoffs

The upside: Full capitation incentivizes prevention. Supplemental benefits attract beneficiaries. Provider-owned MA creates total payer-provider alignment.

The downside: Prior authorization is a constant source of friction. Risk adjustment coding incentives create upcoding concerns. MA plans cost CMS more per beneficiary than traditional Medicare, which is politically contentious.

The Bottom Line

MA is the single most consequential trend in Medicare. Over half of beneficiaries have chosen it. It’s restructuring the economics of healthcare delivery for seniors. But the overpayment question — does CMS pay MA plans more than traditional Medicare would have cost? — is the political time bomb.

What It Is

A CMS Innovation Center model that allows organizations to take capitation-like risk for attributed Medicare fee-for-service beneficiaries. It includes explicit health equity requirements and is the successor to the controversial Direct Contracting model.

Why It Exists

MSSP’s shared savings were seen as too gentle to drive real transformation. REACH was designed to attract organizations willing to take full risk and bring capital, technology, and operational capabilities that traditional providers lack.

The Tradeoffs

The upside: Stronger incentives. Attracts investment. Health equity focus. Pathway to full-risk population health in traditional Medicare.

The downside: Non-provider participation raises concerns about profiteering from Medicare. Some entities have failed financially (CareMax went bankrupt). Critics call it backdoor Medicare privatization. Future administrations may kill the program.

The Bottom Line

REACH is where the policy tension between innovation and protection is most visible. It’s either the future of Medicare transformation or a dangerous experiment in privatization. The answer probably depends on who’s running CMS.

That’s it. That’s the ACO.

What It Is

An Accountable Care Organization is a group of providers that voluntarily takes shared accountability for the quality and total cost of care for a defined Medicare population. About 480 MSSP ACOs cover 11+ million Medicare beneficiaries.

The ACO itself is typically an LLC that sits alongside the participating provider organizations. It doesn’t own hospitals or practices — it coordinates contracts, quality reporting, and shared savings distribution.

Why It Exists

The ACA created ACOs in 2010 as the primary vehicle for moving Medicare from fee-for-service to value. The logic: if providers share in the savings from reducing unnecessary utilization and keeping patients healthy, they’ll invest in prevention and care coordination.

How It’s Organized

The ACO contracts with CMS and is responsible for a population of attributed beneficiaries. “Attribution” means Medicare looks at which primary care doctor a patient saw most often and assigns that patient to the doctor’s ACO.

Inside the ACO, the actual work happens through care managers, data analytics teams, and clinical protocols that try to prevent ER visits, reduce hospital readmissions, and manage chronic disease. The organizational infrastructure that does this work is often a CIN.

The Tradeoffs

The upside: Shifts incentives toward health. Encourages investment in prevention and care management. Can be built on existing structures.

The downside: Shared savings alone may not fund the transformation needed. Attribution is imperfect — patients can see any doctor they want, but the ACO is accountable for their costs. Administrative burden is significant.

The Bottom Line

ACOs are the most important structural experiment in Medicare. They’re not revolutionary — they’re evolutionary, layering shared accountability on top of fee-for-service. The results are modest but real: MSSP ACOs have generated billions in cumulative savings. The question is whether modest savings are enough to justify the complexity.

Walmart tried the same model at scale — and shut down all its health clinics in 2024.

What It Is

A retail clinic is a small healthcare facility inside a retail store (pharmacy, grocery) staffed by nurse practitioners or physician assistants. Limited menu: vaccinations, basic screenings, strep, UTIs, pink eye.

Why It Exists

A large portion of primary care visits are for simple, protocol-driven conditions that don’t require a physician. Co-locating with pharmacies maximizes convenience: diagnose and fill the prescription in one stop.

Retail clinics also serve a strategic purpose for their parent companies. CVS Health owns Aetna (insurance), MinuteClinic (primary care), and CVS Pharmacy (medications). The clinic is the entry point that connects a customer to the broader CVS Health ecosystem.

The Tradeoffs

The upside: Maximum convenience. Transparent pricing. Walk-in access. Integrated with pharmacy.

The downside: Very narrow scope. No ongoing patient relationship. Siloed from the patient’s medical records. Walmart Health’s closure demonstrated the model’s financial fragility when pushed beyond its niche.

The Bottom Line

Retail clinics work for simple, protocolized care. They don’t work as comprehensive primary care — Walmart proved that. The model’s future is probably as a strategic entry point for vertically integrated health companies (CVS/Aetna), not as a standalone business.

What It Is

Direct care at Military Treatment Facilities on bases, supplemented by the TRICARE insurance program that contracts with civilian provider networks. Operated by the Defense Health Agency.

Why It Exists

The military needs doctors who can deploy to combat zones, medics who can treat battlefield trauma, and hospitals that can surge during wartime. TRICARE supplements with civilian care where MTFs can’t meet all needs.

The Tradeoffs

The upside: Comprehensive coverage at minimal cost. Maintains medical readiness. Unified DHA improving standardization.

The downside: MTF quality varies. TRICARE network adequacy can be poor. Transition from military to VA care at separation is fragmented.

The Bottom Line

The MHS is healthcare designed for a purpose beyond healthcare: military readiness. That mission shapes its structure, its capabilities, and its limitations.

What It Is

Virtual-first primary care companies deliver most care through video, chat, and asynchronous messaging, with selective in-person access through owned clinics or partner locations. Amazon One Medical, Firefly Health, Carbon Health, and Galileo are leading examples.

Why It Exists

Traditional primary care has access problems: your PCP is booked three weeks out, only sees patients during business hours, and spends 15 minutes per visit. Virtual-first models use technology to provide faster, more continuous access.

The Tradeoffs

The upside: Dramatically faster access. Lower cost structure. Asynchronous messaging enables ongoing (not episodic) care. Attractive to younger, digitally native populations.

The downside: You can’t do a physical exam through a screen. Building trust and relationships is harder virtually. Most virtual-first companies aren’t yet profitable. State-by-state licensure requirements create regulatory complexity.

The Bottom Line

Virtual-first primary care proves that access is the biggest unmet need in primary care. The question isn’t whether digital care has a role — it clearly does. The question is whether it can replace the in-person relationship, or whether it’s a complement. The market is still figuring that out.

What It Is

About 14,000 urgent care clinics operate nationally, providing walk-in care for non-emergency acute conditions. Extended hours, basic diagnostics (X-ray, labs), no appointment needed.

Why It Exists

Urgent care fills the gap between a primary care office that’s booked weeks out and an ER that’s overcrowded and overpriced. For conditions that need attention today but aren’t emergencies, urgent care is the right-sized solution.

The Tradeoffs

The upside: Convenient, fast, affordable relative to ER.

The downside: No longitudinal relationship with patients. Episodic care that can fragment the patient’s medical record. Variable quality.

The Bottom Line

Urgent care is simple: right-size the care setting to the problem. Not everything needs an ER. Not everything can wait for a PCP appointment. Urgent care sits in the middle.

What It Is

About 6,100 Medicare-certified ASCs perform same-day surgical procedures — orthopedic, ophthalmologic, GI, pain management, and increasingly cardiac and spine. No overnight stays.

Why It Exists

Hospital outpatient departments carry enormous overhead: a sprawling campus, 24/7 staffing, emergency capabilities, teaching infrastructure. ASCs strip all that away. Purpose-built facilities with focused operations, lower overhead, and faster throughput. CMS actively shifts procedures to ASCs to reduce total spending.

The Tradeoffs

The upside: Dramatically lower cost. Higher patient satisfaction. CMS is expanding the ASC-approved procedure list every year.

The downside: Cherry-picks healthy patients. Can’t handle complications requiring overnight stays. Creates revenue tension with hospitals.

The Bottom Line

ASCs are the clearest example of site-of-service economics in healthcare. The same procedure costs dramatically less when you remove the hospital’s overhead. This is one of the few areas where the policy direction is unambiguous: CMS wants more care in ASCs.

What It Is

SUD treatment facilities provide specialized care for addiction across a continuum: outpatient counseling, intensive outpatient programs, residential treatment, and medically managed detox. Medication-assisted treatment — buprenorphine, methadone, naltrexone — is the gold standard for opioid addiction.

Why It Exists

Addiction affects roughly 46 million Americans. For most of history, it was treated as a moral failure, not a medical condition. SUD treatment facilities exist to provide evidence-based treatment in a system that’s still catching up to the science.

The Tradeoffs

The upside: Life-saving treatment. MAT/MOUD is highly evidence-based. Peer support models are uniquely effective. Expanding funding through Medicaid and SAMHSA.

The downside: Fragmented from mainstream healthcare. Quality varies wildly. For-profit chains have faced fraud scandals. Methadone regulations create access barriers, especially in rural areas.

The Bottom Line

SUD treatment is healthcare’s most stigmatized sector. The organizational challenge isn’t clinical — the treatments work. It’s structural: integrating addiction treatment into mainstream healthcare, expanding access in rural areas, and ensuring quality in a sector where bad actors have exploited vulnerable patients.

What It Is

Inpatient psychiatric facilities provide 24-hour psychiatric care in secure environments for patients in acute mental health crises. They range from psychiatric units within general hospitals to standalone psychiatric hospitals.

Why It Exists

After deinstitutionalization closed most state hospitals in the 1960s–80s, the plan was to replace institutional care with community-based treatment. The community treatment infrastructure was never adequately built. The result: a catastrophic shortage of psychiatric beds.

The Tradeoffs

The upside: Essential safety and stabilization. Prevents harm during acute episodes. Structured therapeutic environment.

The downside: Severe national bed shortage. The Medicare IMD exclusion blocks Medicaid funding for facilities with more than 16 psychiatric beds — a policy designed for the era of state institutions that now restricts capacity expansion. For-profit chains face quality and safety allegations.

The Bottom Line

Psychiatric inpatient care is a system in crisis. The bed shortage is real, the consequences are visible in every ER, and the financing barriers (especially the IMD exclusion) are structural. This is one of the most urgent capacity problems in American healthcare.
