Variable copay plans sound good on paper. The idea is simple: charge different copays for higher quality providers, and people will naturally move toward the lower cost options, helping to “bend the cost curve.”

In reality, these designs can make things more complicated for members without tackling the real drivers of healthcare cost. Instead of smarter benefits, we end up with a more confusing experience: one that puts members squarely in the middle of a system they were never meant to navigate on their own.

At the same time, employers are feeling real pressure to act. In Aon’s 2026 Employer Benefits Survey, 62% of respondents ranked “manage healthcare cost and trend” as their number one benefit priority for 2026, up from 38% in 2024 and 33% in 2023. The urgency is growing, but variable copays on their own may not be the answer.

If we truly want to lower costs and improve outcomes, plan sponsors and carriers need to bring quality and cost data directly into the experience of choosing and using care, especially inside the PPO and HDHP plans most people are already in. That means better provider directories, simpler and more visible incentives, stronger primary care, and clearly lower out of pocket costs when members pick higher value providers.

Here’s why variable copay plans may be a short-term fix, and what a better path and long-term strategy looks like.

The Limits of Variable Copay Plans
On the surface, variable copay designs are straightforward: members pay different copays depending on the provider, and that price signal is supposed to steer them toward “better value” options.

But three big issues show up in the real world.

1. They lean too hard on behavioral economics
Variable copays lean on the idea that small, well timed financial “nudges” will reliably
change behavior. In practice, they struggle to:

• Change the fact that most people follow their doctor’s referral, not a price signal in a benefits grid
• Overcome the belief that “more expensive must mean better care”
• Stop people from delaying or skipping needed care because the rules feel confusing or risky

We’ve seen a version of this movie before. Early on, many expected HDHPs to fundamentally change how people used healthcare. They did shift some behavior, but not nearly as much—or as cleanly—as hoped, and there were unintended consequences along the way.

Variable copays risk repeating that pattern: modest behavior shifts at the edges, mixed member responses, and more forgone care. On their own, that’s not a reliable recipe for bending the cost curve.

2. They put members in the middle of clinical decisions
Most people don’t shop for healthcare the way they shop for flights or hotels. When a primary care physician or specialist says, “Go to this lab,” or “Use this imaging center,” they usually go where they’re told.

Variable copays intend to steer members into that referral pathway:

• “You can go where your doctor wants you to go, but you’ll pay more.”
• “If you want to pay less, call this number or use this tool, then go back and
  change your referral.”

That’s a heavy lift for someone who may already be in pain, worried about a diagnosis, or just short on time. Instead of feeling supported, members can feel punished for doing what their doctor recommended, especially if they only find out about the higher copay at the front desk or when the bill arrives.

In the end, the member becomes the go between for financial incentives, plan rules, and clinical decisions. That’s not a fair or effective role to put them in.

3. They move cost around without tackling the real problem
Variable copays also tend to operate at the edges. They change who pays what share of the bill, but they don’t:

• Change contracted rates with providers
• Address the fact that prices for the same service can vary wildly within the same network
• Reduce low value or unnecessary care

So, the hospital that charges three times the benchmark price for an MRI can keep doing exactly that. The only question is whether the member, the plan, or both feel more of that cost. That’s not bending the cost curve; it’s reshuffling the pain.

What Members Actually Need: Integrated Quality and Cost Data
If we want people to choose higher value care, they need something more basic and more powerful than variable copays: clear, trustworthy information on quality and cost, built right into how they find providers and schedule care.

That starts with reimagining provider directories and digital front doors.

1. Provider directories have to move past “name, address, specialty”
Most provider directories are still glorified phone books. They tell members who is in-
network, but not how good the care is or what it’s likely to cost them.

To actually help people make better choices, directories need to function as decision
tools that show:

• Quality: clinical quality measures, complication and readmission rates, appropriateness of care, and when possible, patient reported outcomes
• Cost: expected allowed amounts for this member’s plan, plus comparisons to
  local benchmarks
• Total episode value: where we can, indicators of total episode cost and outcomes (for joint replacement, maternity, cardiac care, etc.), not just one-off visit prices
• Access and experience: appointment availability, telehealth options, patient experience ratings, language, race and ethnicity, and location

With that kind of information, members aren’t flying blind. They can see who’s more likely to deliver better, more culturally competent care at a lower total cost, and employers can line up incentives behind those choices.

Right now, though, most organizations are only partway there. According to Aon’s 2026 Employer Benefits Survey, only 36% of employers are actually steering to higher value providers through plan design. There’s a lot of room to move from concept to execution.

2. Incentives have to be visible at the point of choice
If a plan wants to steer members to higher value providers, those incentives should be obvious and immediate:

• Built into the directory: when someone searches for a provider, those with better quality and cost profiles are clearly tagged (for example, “Preferred,” “Best value,” “Lower out of pocket for you”)
• Clear about out-of-pocket impact: members should see, in the same view, “Estimated cost to you: Y with Provider B”
• Simple and consistent: intead of a maze of tiers and obsure copay rules, stick to a pattern, like lower coinsurance or deductible free coverage when members choose designated high value providers

That’s a very different experience from handing members a chart of variable copays and asking them to guess which providers land in which tier.

How This Works in the PPO and HDHP Plans You Already Have
The good news: we don’t need to rip and replace everything. Traditional PPO and HDHP plans can support strong, value-based steerage when they’re paired with better data and better tools.

At the same time, it’s worth noting that most employers are still operating within these traditional designs. Aon’s 2026 Employer Benefits Survey shows that only 16% of employers have rolled out an alternative health plan. For everyone else, the work has to happen inside the chassis they already have.

1. PPOs with built in value steering
In a PPO environment, plans can:

• Identify preferred providers or centers of excellence based on clear quality and cost metrics
• Surface those preferences directly in the search experience
• Offer meaningful lower member cost sharing for those providers, such as:
  o Reduced copays for office visits and outpatient care
  o Lower coinsurance or waived deductibles for select procedures at preferred facilities
• Align referral patterns by giving PCPs and specialists access to the same quality and cost information, so their recommendations naturally point to the preferred network

The key difference from variable copays is that members can see, in one place, the connection between provider choice, quality, and what they’ll actually pay.

2. HDHPs with real navigation, not just higher deductibles
HDHP members are already very cost sensitive. They’re often paying out of pocket until they hit a sizable deductible. But simply exposing them to more cost doesn’t automatically lead to smarter decisions.

With integrated quality and cost data, HDHPs can:

• Give members personalized, real time estimates before they schedule care
• Highlight higher value providers where the member will pay less for care that’s as
  good or better
• Pair these tools with proactive support such as nurse lines, care advocates, or AI
  powered guides fueled by real-time claims data who can help when someone
  gets a new diagnosis or referral

The goal isn’t to punish member decisions after the fact; it’s to make good choices the easy, obvious ones from the start.

From Shifting Costs to Sharing Information
Variable copay plans were built with the tools available at the time: copays, tiers, and network rules. They were an understandable attempt to influence behavior. But in a world where we can surface real time data at the point of decision, they can feel like blunt instruments compared to what is possible today.

To truly bend the cost curve while protecting the member experience, employers and
health plans should:

• Invest in richer provider directory data that actually reflects quality and cost
• Embed that data across the member journey: search, referrals, scheduling instead of hiding it in separate tools
• Use simple, visible incentives inside standard PPO and HDHP structures that clearly reward high value choices

When members can see which providers deliver better outcomes at lower total cost—and when their benefits clearly reward those choices—we stop putting them in the middle and start putting them in control.

Right now, variable copay plans mostly rearrange who pays and when, without consistently addressing the underlying drivers of cost. They add friction for members, but in many cases, they don’t reliably steer people to better, more affordable care.

The real opportunity is to move away from benefit tweaks and toward data driven steerage: surfacing clear, trusted information on quality and cost in the tools people already use to find care and then backing that up with lower out-of-pocket costs for higher value choices inside familiar PPO and HDHP designs.

Leaders should be watching how quickly enhanced provider directories, digital navigation, and integrated price/quality transparency are evolving and pushing their health plan and navigation partners to show what’s live for their population today, not just what’s on a future roadmap.

From here, the next steps for organizations are straightforward:

• Revisit variable copay and tiered designs to ensure they create more value than confusion
• Set clear expectations with carriers and vendors around plan specific quality and cost data in provider search
• Pilot simple, visible incentives that make higher value providers the default, lower
  cost choice

If employers make cost and quality differences visible, steer people toward high value providers, and strengthen primary care as the front door to the system, they really can bend the cost curve. The goal is simple: make it easy and financially attractive for members to choose better care without putting them in the middle of an already complex system.
