Can an HMO be Self-Funded?

Employers who are exploring level funding or captives often ask the same question early in the process: can we keep our HMO and still move into a self-funded model?

In most cases, no. An HMO is typically built on a capitated payment structure, which is fundamentally different from the fee-for-service claims model used in self-funded plans. That structural difference is the reason you generally cannot self-fund an HMO network like Kaiser.

Why you typically cannot self-fund an HMO

Most HMOs operate on capitation, meaning the health plan pays providers a fixed amount per member, per month, to cover a defined set of services. The financial risk and payment mechanics sit inside the HMO’s model.

Self-funding requires something else entirely, a claims-based, fee-for-service structure where the employer’s plan pays claims as they occur, supported by stop-loss protection and plan administration.

Those two models do not line up cleanly, which is why self-funding a traditional HMO is usually not an option.

The practical implication for employers with Kaiser or other HMOs

If your workforce is heavily enrolled in Kaiser, Sharp, or another HMO structure, moving into level funding or a captive often requires a network shift. That is not always a dealbreaker, but it is a real change management issue.

The alternative that often works, EPOs

For employers who want a more controlled network, but need a plan structure that can be self-funded, an EPO can be the bridge.

An Exclusive Provider Organization (EPO) is:

  • In-network only, similar to an HMO experience for employees
  • Structured like a PPO from a contracting standpoint, fee-for-service claims
  • Compatible with level funded, captive, and self-funded arrangements

One clean way to think about it is this: an EPO can preserve the simplicity of in-network-only care, but it sits inside a PPO-style claims model, which is what makes self-funding possible.

“An EPO is an in-network only product, but it’s a PPO, so it’s a fee-for-service contract model, and we can self-fund it.”

When moving from an HMO to an EPO makes sense

An HMO-to-EPO transition is usually worth evaluating when:

  • Your organization wants the transparency and cost controls that come with level funding or a captive
  • You are not locked into an HMO network as a cultural expectation
  • You want an in-network-only plan option that can still be self-funded
  • You need a smarter long-term approach than fully insured renewals

If your population is heavily PPO today, or you have flexibility in network preference, level funded or captive options tend to be much easier to implement.

What to evaluate before making the switch

A responsible evaluation should include:

  • Current enrollment split, HMO vs PPO
  • Network disruption risk, locations, provider access, employee sentiment
  • Claims history and underwriting fit for level funding or captive options
  • EPO availability and network strength in your geography
  • Communication plan for employees, especially if Kaiser is widely used

At Parker Insurance, we look at this as an engineering problem, not a sales pitch. The right solution depends on the group’s current coverage, demographics, and what employees will realistically accept.

FAQ: Self-Funding HMOs

Can you self fund Kaiser?

Generally, no. Kaiser is an HMO built on a capitated model, which does not align with the fee-for-service structure required for self-funding.

Can you self fund an HMO plan at all?

Typically not in the traditional sense. Most HMO models are capitated, and self-funding requires a claims-based fee-for-service contract structure.

What’s the closest option to an HMO in a self-funded plan?

An EPO is often the closest fit. It is in-network only like an HMO, but it is built on a PPO-style fee-for-service model that can be self-funded.

What is an EPO?

An Exclusive Provider Organization (EPO) is an in-network-only plan design. Members must use participating providers except for emergencies, but the plan is structured to support claims-based funding.

If we are currently on Kaiser, can we move to level funding?

Possibly, but it usually requires changing plan networks. Whether it is worth it depends on demographics, claims experience, and how “married” the workforce is to Kaiser.

What is the first step if we want to explore this?

Start with a feasibility review. The key is comparing your current HMO renewal against level funded and captive options that are realistic for your population, including EPO alternatives when needed.

EPOs and Other In-Network-Only Plans Are An Option

You generally cannot self-fund an HMO network, because the payment model is not built for it. If your goal is to move into level funding or a captive, the path is usually through a PPO-based structure, and in many cases, an EPO can deliver an HMO-like in-network experience while still supporting self-funding.
