Warren Bill Would Bar Private Equity and Insurers from Owning Medical Practices

Sen. Elizabeth Warren, joined by 12 other Democratic lawmakers, has introduced bicameral legislation that would prohibit for-profit corporations—private equity funds and insurers among them—from owning medical practices. The bill also targets management services organizations, the back-office entities that increasingly run the business side of clinics, barring them from controlling those offices. It is modeled on an Oregon law that took effect this year and has already been used by physicians in Eugene to block a corporate takeover. Enforcement is layered across three paths: the FTC, state attorneys general, and a private right of action for physicians carrying treble damages, paired with mandatory divestment—teeth that backers say earlier corporate-practice-of-medicine laws lacked.

The push responds to a steep consolidation of the industry. Private equity’s health care investment climbed from $5 billion in 2000 to $104 billion in 2024, and as of this year 82 percent of physicians work for hospitals or other corporate entities, up 20 points from 2019. Research cited by the sponsors links private equity ownership to higher costs and worse patient outcomes, particularly in nursing homes, since the profit motive tends to override patient care.

The timing is tied to affordability pressure: employers expect health-plan costs to rise about 11 percent per worker in 2027, and ACA plan costs are also projected to jump. The bill aims to keep medical decision-making with doctors rather than Wall Street investors.
