Value-based contracts require a different network.

Most organizations approach the shift to value-based care as a payment model change. It is. But it's also a network infrastructure change — and that second part gets underestimated almost every time.

A network built for fee-for-service is volume-driven, specialty-heavy, and organized around the largest health systems in a market. That design makes sense when you're trying to maximize covered lives, minimize access complaints, and keep employers from pulling their business. It is the wrong network for accepting financial risk on a population.

We have seen organizations sign capitated contracts, begin attributed population management, and then discover — three months into the arrangement — that their PCPs aren't willing to accept the care coordination expectations, their specialists don't close the referral loop, and nobody in the network has any experience with HEDIS measure management. The payment model changed. The network didn't. That mismatch is expensive to fix after you're in the contract.

FFS vs. value-based: what changes in the network

In a fee-for-service model, adequacy is the standard. Sign enough providers of each type to pass time-and-distance thresholds. Patient volume routes wherever it routes. Claims come in, claims get paid. Nobody has to agree on anything beyond the fee schedule.

Value-based care changes all of that. The model requires attributed population management — you have a defined population of members who are assigned to specific PCPs, and you are financially accountable for their total cost of care and quality outcomes. That means you need PCPs who will accept attribution, actively manage their panels, coordinate referrals to in-network specialists, and report quality data back to the plan. Adequacy as a concept doesn't describe this. Engagement does.

The panel size problem is real and underappreciated. A PCP who is paneled with twelve plans and carrying 2,800 patients is not a meaningful network partner for value-based care. They are managing volume. They don't have capacity for the proactive outreach, the care gap closure calls, the care management referrals that a risk arrangement requires. You need willing and capable PCPs with actual panel capacity. That list is smaller than your adequacy roster suggests.

Specialists matter differently in a value-based network, too. The key question is whether they close the loop — do they send discharge summaries, communicate with the referring PCP, document to diagnosis rather than just to encounter? A specialist who generates high volumes of downstream testing and referrals but communicates nothing back to the primary care team is a liability in a risk arrangement. In FFS, they're just a provider.

What to assess before signing a value-based contract

If you're evaluating whether your existing network can support a value-based arrangement — or building a new one specifically for a risk contract — here is what actually matters:

• PCP panel capacity and attribution methodology. How many of your PCPs have open panels? How many are actively accepting new Medicare Advantage or Medicaid patients? Attribution works differently across plans and contracts — understand how members will be assigned and whether your PCPs have capacity to absorb them.
• EHR and HIE connectivity. Can your PCPs receive care gap alerts electronically? Can you share population health data with their practice management systems? A PCP who works out of a paper-based system or an EHR that doesn't interface with your HIE is a limited partner in a value-based arrangement, regardless of how good a clinician they are.
• Current quality program participation. PCMH designation, ACO participation, Bridges to Excellence recognition — these signal that the practice has already built the infrastructure for quality reporting. Practices that have never participated in a quality program will require more onboarding time and more ongoing support.
• Willingness to participate in care coordination protocols. Ask directly. Some physicians are enthusiastic about collaborative care models. Others want to practice independently and view care coordination expectations as administrative burden. Know which you're contracting with before the arrangement starts.
• Historical performance on HEDIS or comparable measures. If you can access performance data — through a prior plan relationship, through an ACO's public reporting, through state Medicaid quality data — use it. Past quality performance is the best predictor of future quality performance.

Building the network differently

If you're building a new network specifically for a value-based or risk arrangement, the structure should reflect the model from the beginning. That means a few things that are different from a standard adequacy build.

Tier the provider panel from the start. Separate preferred providers — high quality, care coordination willing, panel capacity available — from standard network providers who meet adequacy requirements but aren't positioned for active population management. Use contract language to establish quality incentive thresholds for preferred tier participation. Give providers a reason to be preferred partners, not just network participants.

Build smaller, deliberately. Eighty highly engaged PCPs outperform two hundred indifferent ones for risk-based work. A smaller, higher-quality network is operationally easier to manage, produces better quality outcomes, and creates stronger provider relationships. Adequacy filings may require a minimum number of providers — but beyond the minimum, density without engagement is noise.

Plan for the transition honestly. If you're inheriting an FFS network and converting it to support a value-based arrangement, expect attrition. In our experience, 20 to 30 percent of providers will disengage — either formally terminating or effectively going inactive — when care coordination expectations are introduced. That attrition is manageable if you plan for it. It is a crisis if it surprises you six months into a capitation arrangement.

Adequacy gets you approved. Engagement is what makes a value-based network actually work.

If you're building a network for the first time in a risk arrangement, build it for engagement, not just coverage. The adequacy filing is a floor. The value-based performance is built on what's above it — and the providers who will do that work are identifiable before you contract, if you know what to look for.
