The Slow Erosion of the Traditional Provider Network

Why It Matters

The erosion of traditional networks challenges insurers’ core value proposition and forces them to innovate or lose employer business, reshaping cost structures across the U.S. health‑care market.

Key Takeaways

• Small‑employer self‑funding grew 10 points, reaching 27% in 2025
• Level‑funded coverage surged to 37% of small firms by 2025
• Employers now see cash prices undercutting contracted rates after price‑transparency rules
• UnitedHealthcare projects up to 750,000 new self‑funded members this year
• Direct‑contracting deals, like Northwell‑32BJ, signal growing network‑free alternatives

Pulse Analysis

The migration toward self‑funded and level‑funded health plans is reshaping employer risk appetite. Small employers, once reliant on fully insured policies, have embraced self‑funding at a 10‑point rise over the past decade, while level‑funded options now cover more than a third of this segment. This shift gives employers direct claim visibility, exposing the limited price leverage traditionally offered by insurer‑maintained provider networks. As a result, cost‑containment strategies such as high deductibles and narrow networks face heightened scrutiny.

Price‑transparency regulations introduced in 2024 have amplified employer scrutiny by revealing stark disparities in negotiated rates versus cash prices. Data shows many networks fail to deliver the assumed discount advantage, prompting employers to explore alternatives like reference‑based pricing, cash‑pay programs, and direct contracts with health systems. High‑profile pilots—Northwell Health’s direct‑contracting with the 32BJ Health Fund, Mark Cuban’s Cost Plus Wellness platform, and AdventHealth’s internal narrow‑network model—illustrate a growing appetite for network‑free solutions that promise predictable costs and greater provider choice.

Looking ahead, the momentum is likely to intensify. UnitedHealthcare projects up to 750,000 new self‑funded members this year, while CMS plans to allow non‑network plans on the ACA marketplace starting in 2028. Incumbent carriers are responding by launching hybrid offerings—designated orthopedic networks, ICHRA products, and transparent, no‑deductible plans—to retain employer loyalty. The convergence of regulatory change, employer cost pressure, and emerging direct‑contracting models suggests a gradual but irreversible erosion of the traditional provider network, compelling insurers to re‑engineer their value propositions or risk marginalization.
