Where the debate stands
Insurers that also own physician groups, pharmacy benefit managers and care delivery assets have faced bipartisan criticism all year. At January hearings, lawmakers from both parties questioned the CEOs of the largest insurers on how integration affects access to care. In February, Sens. Elizabeth Warren and Josh Hawley introduced the Break Up Big Medicine Act. It would bar a company from owning both an insurer or PBM and a provider or management services organization, give violators one year to comply, and appoint a trustee to sell assets if divestiture does not happen.
No major law has passed. But Democrats have reportedly discussed breakup proposals if they win the House in November, and public attention keeps rising. UnitedHealth reported more than $447 billion in revenue last year, and a July 2025 report counted nearly 2,700 companies in its structure.
The evidence is mixed
Research does not point in one direction. A federal inspector general report in May found that enrollees without financial assistance in vertically integrated Part D plans paid lower premiums but nearly 40% more out of pocket for the drugs studied. A September study of nearly 300 ambulatory surgery centers acquired by UnitedHealthcare found no decline in procedure volume or quality and lower negotiated facility prices. Policymakers on both sides will use these findings selectively.
Why hospital leaders should care
In some markets, a major insurer is also a large employer of physicians and a direct competitor for outpatient volume. That affects referral patterns, site-of-care steering and contract negotiations. A forced breakup could release physician groups, surgery centers and home health agencies into the market, creating acquisition or partnership opportunities. Continued growth of integrated companies, by contrast, would deepen competition for primary care relationships.
- Map your exposure. Identify which local physician groups, surgery centers and post-acute providers are owned by insurers, and how much of your volume they influence.
- Track referral leakage. Measure where patients attributed to insurer-owned practices receive imaging, surgery and specialty care.
- Prepare for divestitures. Decide in advance which assets you would want if they came to market and how you would fund them.
- Engage on policy. Make sure lawmakers hear how integration affects your patients and contracts, using local data.
