Self-insured employers cover roughly two-thirds of the 165 million Americans with job-based coverage, yet they continue to face steep and rising health costs despite a decade of federal transparency efforts. According to interviews with employers, benefits consultants, claims administrators, and legal and policy experts, price disclosure alone has not given most companies the leverage to negotiate lower prices.
In theory, organizations that pay medical claims directly should have the clearest view into spending. In practice, they depend on third-party administrators, or TPAs, to build provider networks and process claims. The arrangement can work when incentives align, experts said, but often the TPA’s financial interests diverge from the employer’s.
Several market specialists pointed to fee structures that can drive costs up rather than down. One commonly cited charge is a shared savings fee. A legal expert described a hypothetical scenario in which a provider issues a $100,000 bill, a TPA negotiates it down to $1,500, then bills the employer $30,000 for securing the discount. The employer would see a $31,500 claim, and, as the expert put it, “I don’t think they really tell you that $30,000 of that is a fee.”
Even when employers receive itemized fee information, options remain constrained. Large national carriers have acquired many independent administrators and bundled specialty vendors, leaving few alternative partners. Changing TPAs can also require switching provider networks, a move that often meets resistance from employees.
Experts highlighted potential fixes, including tighter contract terms that cap fees and guarantee access to data, stronger transparency rules with meaningful enforcement, and clearer guidance on whether administrators share fiduciary responsibility for prudent plan spending. Each path has limits. Enforcement attention tends to flow to the largest employers, and information alone does little when there is no credible alternative to negotiate against.
A subset of self-insured employers has tried stepping outside the prevailing model. Some have struck direct contracts with local health systems. Others have shifted to fully insured arrangements or guided workers to Affordable Care Act marketplaces with defined employer contributions. These strategies can work, but they typically require a geographically concentrated workforce, significant administrative capacity, or a stable individual market.
Self-insured employers and transparency limits
Congress enacted new transparency provisions for pharmaceutical benefit managers this year in the Consolidated Appropriations Act of 2026. The measures require extensive disclosures to employers and restrict some PBM fee practices. Experts say that to materially reduce costs, rules must extend beyond disclosure. They argue for enforcement mechanisms that do not assume every employer has the leverage and resources to police its own rights, and for reforms that reach beyond PBMs to address an industry landscape where consolidation can leave employers with little practical ability to take their business elsewhere.
