Designing a Flexible Provider Network for Self-Funded Plans

Self-funded employers, third-party administrators (TPAs), regional carriers and benefits consultants rarely serve one uniform population. A workforce spread across three states, a client base split between urban and rural markets, or a membership that shifts every renewal cycle all run into the same wall: a single, fixed network was never built to flex with any of it.

Regulators have already caught up to this problem from the other direction. The National Association of Insurance Commissioners has spent the last decade tightening network adequacy standards specifically because narrow, one-size-fits-all networks left members without reasonable access to care. A flexible network design solves that same access problem from the plan sponsor’s side: instead of forcing a population into whatever a single network happens to cover, the network is assembled around the population.

This guide covers how to design a flexible provider network in practice: combining core, wrap and complementary coverage, deciding when to tier or narrow, building for multistate or dispersed populations, and weighing the build, rent and blend paths available to get there.

How to design a flexible provider network: Combining core, wrap and complementary coverage

A flexible network design is rarely one network. It is usually three layers working together, each solving a different problem.

A core network is the primary contracted network a plan runs on day to day: the hospitals, health systems and physician groups that cover the bulk of the population in its main service area.

A wrap network is a supplemental layer added on top of the core to fill specific gaps, usually geographic, without renegotiating the core contract itself.

A complementary network adds a specialty or service line the core network is thin on, such as behavioral health, musculoskeletal care or high-cost specialty facilities, so the plan does not have to pay out of network for services its core network was never built to cover well.

Combining the three lets a plan sponsor keep the stability and pricing of an established core network while patching exactly the gaps that matter for its own population, instead of buying a bigger, more expensive network to solve a problem that only exists in a handful of zip codes or a single service line.

MagnaCare’s provider network can be rented in full or in pieces specifically for this purpose. A plan can lease core coverage, add wrap access for out-of-area members, or layer in a complementary network for a specific specialty gap, all without building any of it from the ground up.

When to tier a network and when to narrow it

Once the core, wrap and complementary layers are in place, the next design decision is how tightly to steer members within them. Tiering and narrowing both push utilization toward higher-value providers, but they solve different problems and carry different risks.

Tiering keeps the full network available but splits it into cost-sharing levels, so members pay less at preferred, higher-value providers and more everywhere else. It works well when a plan wants to influence behavior without restricting access, and it is often the lower-friction starting point for a population that has not been steered before. MagnaCare’s tiered benefit design applies this model against its own preferred provider organization (PPO) network, letting the plan sponsor choose which providers land in which tier.

Narrowing removes lower-value providers from the network entirely rather than pricing around them. It produces deeper savings but only works where the remaining network is genuinely adequate: enough provider density, enough specialty coverage and enough geographic reach that members are not left without a real in-network option. A narrow network built in a market with thin provider competition tends to create exactly the access complaints that draw regulatory attention. Before narrowing, pull claims data on where members actually receive care today and map it against the proposed network footprint, not the other way around.

A useful rule of thumb: tier first in a market with strong provider density and mixed population needs, and reserve narrowing for a defined subset of the population, a specific specialty, or a market where the data clearly supports it.

Designing coverage for multistate and dispersed populations

A single regional core network rarely travels well. Peterson-KFF’s research on employer network strategy found that direct contracting, one of the more common ways employers try to build coverage themselves, reached only a small share of large self-funded employers as of its most recent count, in large part because building adequate provider relationships in every market a population touches is slow and resource-intensive.

For plans with members outside a core network’s primary footprint, whether that is a handful of remote employees, a multistate workforce or a fund with members scattered across several locals, the faster path is layering in wrap or leased coverage in the specific markets that need it, rather than rebuilding a national network from scratch.

MagnaCare has built this specifically for multistate coverage: a plan can run on MagnaCare’s core network in its primary service area and add national provider partners for members located elsewhere, without a separate implementation for each state. See how this works for multistate populations in more detail.

Build, rent or blend: Weighing the tradeoffs

Every flexible network design eventually comes down to one decision: build the network directly, rent access to one that already exists, or blend the two.

Building a network through direct contracting gives a plan the most control over rates and provider relationships, but it takes time, requires in-house contracting expertise, and is only practical at a meaningful scale. It is also the least common path: direct contracting reached 8 percent of large self-funded employers as of the most recent Peterson-KFF data cited above.

Renting or leasing a healthcare network trades some of that control for speed. A leased network gives immediate access to an established, credentialed provider base and a working rate structure, with no contracting timeline to manage.

Blending the two, an owned or leased core network with rented wrap and complementary layers added where the population actually needs them, is usually the fastest route to a network that is genuinely built around a specific population rather than a generic national footprint. For a closer look at how to weigh these options against a plan’s own priorities, see how to evaluate healthcare network solutions.

MagnaCare’s network can support any point on that spectrum. A plan can lease the full network, rent only the pieces it is missing, or combine a leased core with a wrap layer for out-of-area members, assembling a custom design without the multi-year timeline that direct contracting requires.

Frequently asked questions

How does a wrap network differ from a leased network?

A wrap network is added on top of an existing core network to fill specific gaps. A leased network is a full network access arrangement that can serve as the core itself. A plan can lease a network and still add a wrap layer on top of it if the leased network has its own coverage gaps.

How long does it typically take to add wrap coverage to an existing core network?

Because a wrap network uses provider relationships that are already contracted and credentialed, adding one is measured in weeks rather than the months or years direct contracting can take. Timelines vary based on how many markets are involved and how quickly eligibility and claims routing can be updated on the plan’s side.

Can a flexible network design combine more than one leased network?

Yes. Plans with members in several distinct markets sometimes lease more than one regional network rather than relying on a single national wrap, particularly when provider quality or contract terms vary meaningfully by region. The tradeoff is more vendor relationships and claims paths to manage, which is where a single partner offering multiple network configurations under one contract simplifies administration.

What happens to network flexibility if a self-funded plan switches TPAs?

Network access and TPA administration are not automatically tied together. A plan that owns or leases its network directly, rather than relying on whatever network its TPA happens to bundle in, can generally carry that network access through a TPA transition. This is worth confirming in the network contract itself before a TPA change is underway, not after.

Turning network flexibility into a working strategy

Designing a flexible network is not a one-time project. Populations shift, new markets get added and provider performance changes, so the layers that make up a network need to be revisited as the plan evolves, not locked in at renewal and left alone.

MagnaCare operates its provider network directly, which means the organization a plan contracts with is the same one managing provider relationships, credentialing and rate negotiation. Combined with à la carte rental options across core, wrap and complementary coverage, self-funded employers, TPAs, regional carriers and consultants can assemble a network that fits a specific population without taking on the operational burden of building one from scratch.
