A new report from the Physicians Advocacy Institute, prepared by Avalere Health, confirms what many physicians and provider organizations already feel in the market: independent physician practice is rapidly disappearing. The April 2026 PAI-Avalere report, Escalating Consolidation: The Rapid Expansion of Hospital and Corporate Control Over Physician Practices and Employment 2018-2026, tracks physician employment and practice ownership trends over an eight-year period. The numbers are striking.

As of January 1, 2026, 82% of physicians were employed by hospitals or corporate entities. Only 18% remained in physician-owned practice settings. The report also found that 63.9% of physician practices are now owned by hospitals or corporate entities. This is not a temporary market fluctuation. It is a structural shift in American healthcare.

The Key Numbers

According to the PAI-Avalere report:

• 82% of physicians are now employed by hospitals or corporate entities.
• 59.7% of physicians are employed by hospitals.
• 22.3% of physicians are employed by corporate entities, including insurers, private equity firms, and other corporate owners.
• 63.9% of physician practices are owned by hospitals or corporate entities.
• Corporate ownership of practices, at 33.2%, now exceeds hospital ownership, at 30.6%.
• From 2018 to 2026, 253,000 additional physicians became employees of hospitals or corporate entities.
• Over the same period, 85,000 additional physician practices were acquired by hospitals or corporate entities.

The rural data is equally important. By January 2026, 80.2% of rural physicians were employed by hospitals or corporate entities, and 67.8% of rural practices were owned by hospitals or corporate entities. The consolidation trend is not limited to major urban markets.

Why This Matters for Providers

For physicians and other healthcare providers, consolidation changes leverage. Independent practices historically controlled their operations, referral relationships, payer negotiations, staffing, clinical workflows, and compliance culture. As employment and ownership shift to hospitals, insurers, private equity platforms, and corporate entities, those decisions increasingly move away from the individual provider.

That can create operational efficiencies. But it also creates risk. Employed physicians may face productivity targets, coding pressure, referral expectations, payer alignment strategies, or documentation mandates set by non-clinical leadership. Independent providers competing against consolidated systems may face narrower networks, aggressive contracting pressure, reduced reimbursement leverage, and increased acquisition pressure.

For behavioral health, SUD, ABA, outpatient mental health, and specialty providers, the report is also a warning. The same market forces affecting physician practices are increasingly affecting non-physician provider sectors. Capital, payer control, platform growth, MSO structures, and acquisition strategies are reshaping provider independence across healthcare.

Corporate Ownership Brings Different Compliance Questions

The report does not separate all corporate owners by type, but it identifies the category as including insurers, private equity firms, and other corporate entities. That distinction matters. A hospital-owned practice, insurer-owned practice, private equity-backed platform, and founder-owned independent practice do not operate under the same incentives. Their compliance risks may differ as well.

Providers should pay close attention to:

• Who controls clinical operations;
• Who controls payer contracting;
• Whether compensation creates coding or utilization pressure;
• Whether referral patterns are being directed;
• Whether medical necessity determinations are clinically independent;
• Whether MSO or management fees are commercially reasonable;
• Whether physician judgment is protected in writing; and
• Whether the practice can survive payer audits, SIU investigations, and regulatory review.

The legal question is no longer only who owns the practice. The better question is who controls the decisions that affect patient care, coding, billing, referrals, documentation, and payer reimbursement.

Provider Call to Action

Physicians, behavioral health providers, SUD programs, ABA organizations, outpatient mental health providers, and other provider organizations should use the PAI-Avalere report as a reason to reassess their ownership, employment, MSO, payer, and compliance structures. Independent providers should evaluate whether they have enough contractual, operational, and compliance protection to remain viable. Employed or acquired providers should review whether clinical independence, documentation integrity, compensation terms, and audit responsibilities are clearly protected.

Bottom Line

The PAI-Avalere report confirms that physician practice has crossed a major threshold. Hospital and corporate control is now the dominant model. For providers, the strategic issue is not simply whether consolidation is good or bad. The issue is whether the provider understands the legal, financial, payer, and compliance consequences before independence is lost or control is transferred.
