Key Takeaways
- • Private equity investment in physician practices and health care staffing companies has surged in recent years, with PE-backed entities playing a central role in driving out-of-network surprise medical billing that increased both in-network and out-of-network payments while exposing consumers to unexpected costs.
- • Private equity investor groups spent millions on lobbying efforts to block federal surprise medical billing legislation, delaying passage until Congress enacted the No Surprises Act in late 2020, demonstrating industry influence over health care policy.
- • The USC-Brookings Schaeffer Initiative white paper identifies private equity as a "divining rod for market failure," suggesting PE investment reveals and exploits existing structural weaknesses and legal loopholes in the U.S. health care system rather than necessarily creating problems de novo.
- • The analysis distinguishes between PE as an inherent problem versus PE as a symptom of deeper market dysfunction, questioning whether other capital sources—public equity, venture capital, health systems, and insurers—would similarly exploit health care market failures absent private equity involvement.
- • Proposed policy responses include increased transparency requirements for private equity ownership of physician practices to regulators and policymakers, alongside modifications to federal tax policy to address incentive structures enabling value extraction.
Summary
Institutional private equity investment in health care has expanded substantially, with particular concentration in physician practices and staffing companies, raising policy concerns that profit-driven capital may degrade patient care quality or elevate costs. The USC-Brookings Schaeffer Initiative for Health Policy, a collaborative research partnership between Brookings' Economic Studies Program and the USC Schaeffer Center for Health Policy & Economics, examined these dynamics in a white paper supported by Arnold Ventures.
A prominent case study illustrates the mechanisms of PE-driven market exploitation: private equity-backed physician staffing companies and air ambulance operators became primary drivers of out-of-network surprise medical billing, a practice generating unexpected financial burdens for consumers while simultaneously increasing both in-network and out-of-network payment rates across the system. Rather than passively accepting regulatory constraints, PE investor groups mounted substantial lobbying campaigns to obstruct federal legislation addressing these practices, successfully delaying congressional action until the No Surprises Act passed in late 2020.
The white paper's central analytical framework reframes the private equity question: rather than treating PE as an autonomous source of market harm, the authors characterize private equity investment as a "divining rod for market failure"—a mechanism that reveals and exploits pre-existing structural vulnerabilities and legal gaps in American health care. This distinction proves consequential for policy design. The analysis remains agnostic on whether private equity itself constitutes the core problem or whether alternative capital sources—including public equity investors, venture capital firms, health system operators, and insurance companies—would identically capitalize on the same market failures and regulatory loopholes in PE's absence.
The initiative identifies concrete policy levers for addressing harmful PE acquisitions, including mandatory transparency mechanisms enabling regulators and policymakers to track private equity ownership of physician practices, and targeted modifications to federal tax policy designed to constrain financial incentive structures that facilitate value extraction from health care operations. These recommendations reflect an evidence-based approach to health care policy grounded in rigorous analysis rather than categorical restrictions on PE participation in the sector.
