Different Stories, Same Direction

Hawaii’s major health insurers began with different histories, but healthcare financing is moving toward tighter control over payment, data, networks, referral pathways, care management, and pieces of delivery infrastructure.

By Esther Yu Smith, MD | Healthcare governance analysis

UnitedHealthcare, Kaiser Permanente, and HMSA should not be treated as identical organizations. The public question is whether their different histories still protect patients, physicians, small practices, and rural communities as insurer governance becomes more closely tied to payment, data, networks, and care management.

News analysis

Hawaii’s largest health insurers do not share the same origin story. UnitedHealthcare grew out of the national managed-care industry, Kaiser Permanente developed from a prepaid medical model that joined financing and delivery, and HMSA began as a local nonprofit shaped by social workers trying to make medical care affordable.

Those histories still appear in public messaging, especially for HMSA, which describes itself as a local nonprofit health plan with deep Hawaii roots . Hawaii can respect that history while still asking how much it describes the organization’s present structure, especially as healthcare financing moves toward tighter control over payment, data, networks, referral pathways, care management, and pieces of delivery infrastructure.

UnitedHealthcare and the national corporate model

UnitedHealthcare is the clearest example of the national corporate model because it did not begin as a Hawaii institution. The company traces its roots to Charter Med, founded in Minnesota in 1974 by Richard Taylor Burke, and then to United Healthcare Corporation in 1977, when managed care was expanding as a way to organize benefits, build networks, administer claims, manage employer health costs, and control utilization. For current structure, the stronger source is UnitedHealth Group’s 2024 annual report , which describes the company’s major businesses as UnitedHealthcare and Optum.

From the beginning, UnitedHealthcare belonged to a business model that treated healthcare as something to be organized through scale, actuarial risk, contract design, employer accounts, administrative systems, data, and utilization management. It did not begin with island patients trying to find doctors, rural clinicians trying to keep practices open, or families trying to survive the cost of illness.

That origin helps explain what UnitedHealth Group has become: one of the largest healthcare companies in the world, with business segments that include UnitedHealthcare and Optum, its health services arm. UnitedHealth’s annual report describes Optum as spanning patient care, care management, wellness and consumer engagement, data and analytics, technology, pharmacy care services, and health care operations.

When a single corporate organization has influence over insurance coverage, provider networks, data systems, care management, pharmacy services, and other parts of healthcare administration, decision-making becomes concentrated within that organization rather than being distributed among independent insurers, physicians, hospitals, and patients.

Kaiser Permanente and the power of integration

Kaiser Permanente began from a different place. Its early history is usually traced to Dr. Sidney Garfield and Henry J. Kaiser , who developed prepaid medical care for workers and families and built a model that connected financing and care delivery more tightly than conventional insurance.

Kaiser grew from industry, employment, hospitals, worker productivity, and the practical need to organize care for large workforces, so its founding structure mixed medical logic with business logic from the start. Its model placed doctors, hospitals, prevention, and payment inside one coordinated system, which can solve a real problem in American healthcare, where patients are often bounced among insurers, offices, hospitals, authorizations, bills, portals, and phone trees until the care plan starts to look like a Rube Goldberg machine wearing a stethoscope.

Integration can make a system easier to coordinate, but it also concentrates the power to define the patient’s path. Kaiser Permanente describes itself as an integrated care system , and that structure distinguishes it from a conventional insurer. A system that coordinates the plan, doctors, hospitals, data, and care pathways may move more efficiently than a fragmented insurer, while giving patients and physicians fewer places to push back when the system’s decision does not fit the patient’s situation.

Kaiser now operates inside a national healthcare institution with regional administrations, legal departments, compliance systems, technology platforms, brand management, executive leadership, capital planning, standardized procedures, and layers of governance that can be difficult for local patients and clinicians to influence. In Hawaii, a thin specialist network, a closed panel, or a standardized process that fails to match island realities can leave patients with few practical alternatives.

HMSA and the test of difference

HMSA is the central Hawaii case because its public identity depends most heavily on being seen as different. According to a Kauai Now article marking HMSA’s 85th anniversary , HMSA began in 1938 after Margaret Catton, a nurse and social worker, proposed a nonprofit, community-based organization through which members could pool money to make medical care more affordable. The same account says HMSA opened with 671 members, mostly teachers and social workers.

That origin deserves respect because it came from people looking directly at a human problem. Families needed care, bills could ruin them, and a community-based nonprofit plan offered a practical way to make medical care more reachable.

The current HMSA board reflects the kind of leadership network often found at major statewide institutions. According to HMSA’s public leadership page , its directors include executives and leaders from finance, retail, hospitality, philanthropy, education, healthcare, and other sectors that play significant roles in Hawaii’s economy and civic life.

One example illustrates how interconnected those institutions can be. HMSA identifies Robert Harrison , chairman, president, and chief executive officer of First Hawaiian Bank, as chair of its board. Separately, First Hawaiian’s corporate governance disclosures list HMSA president and CEO Mark Mugiishi as a director of both First Hawaiian, Inc. and First Hawaiian Bank. The overlap does not imply wrongdoing, but it highlights how leadership circles among Hawaii’s largest organizations can intersect and reinforce one another.

Board composition decides which kinds of experience sit close to power. A board drawn from large institutions will tend to recognize reserves, employer relationships, reputation, compliance, market position, political risk, and institutional stability as urgent problems because those are the problems its members have been trained to see.

A rural physician looking at the same system sees a different set of risks: whether payment covers rent, staffing, malpractice, billing, supplies, payroll taxes, technology costs, prior authorization work, and the cost of living in Hawaii. A patient sees whether anyone is taking new patients, whether the specialist has an opening, whether the referral was approved, whether the office has enough staff to answer the phone, and whether there is any real recourse when the answer is no.

Why governance belongs in the access conversation

HMSA’s claim of difference has to be judged against this present structure, not only against its origin story. A local nonprofit insurer can become more like the national corporate model through governance, contracting power, data control, care management, administrative reach, and vertical integration, even while it continues to speak in the language of community.

Vertical integration sharpens the question because it blurs the old line between payer and provider. When one organization, or one closely connected set of organizations, gains influence over financing, network rules, referral pathways, quality metrics, data systems, care management, and delivery infrastructure, patients and physicians may not see how much the options have narrowed until the narrowing has already been built into the system.

The legal differences among these organizations are real, and Hawaii should not flatten them. UnitedHealthcare is part of a shareholder-driven national corporation, Kaiser is a national integrated healthcare system with a physician and delivery-system history, and HMSA is a local nonprofit insurer with a social-work origin.

Those differences should guide the analysis, but they cannot end it. Hawaii should judge these organizations by what they control now, what they are becoming, and whether patients, physicians, small practices, and rural communities have meaningful influence over the decisions that determine whether care remains available.

HMSA’s history explains why its public message still has force, but history is not governance. If HMSA asks Hawaii to see it as different from the national corporate healthcare model, Hawaii should ask what still makes it different in practice as its board, contracting power, administrative systems, data reach, and any future vertical integration move it closer to the same model it asks the public to look past.
