Vertical Integration Drives Higher Healthcare Costs and Limits Patient Choice

Patient Cases Illustrate Cost Shifts
After a failed in-vitro fertilization cycle, Anne Hug, a radiology professor, was told she needed a uterine polyp removed. Guidelines allow the procedure in a doctor’s office with local numbing, and her physician initially estimated about $3,000. The hospital system that owned the practice later redirected her to a freestanding surgery center it acquired in 2025, where the bill rose to roughly $6,000. Hug declined anesthesia, received brief cervical numbing, and completed the removal in minutes, yet was forced into a higher-priced venue.
A separate patient, identified only as Ari H., switched to an Aetna plan that automatically enrolled him in the insurer’s specialty pharmacy network. His three high-cost specialty drugs, previously subsidized by manufacturer copay assistance, now required him to pay the full deductible and out-of-pocket maximum, with the assistance funds flowing back to the insurer. He described the situation as “double-dipping.”
Both stories show how vertically integrated health systems can steer patients toward more expensive settings or pharmacy networks, even when clinical guidelines suggest cheaper alternatives.
Background and Context
Over the past decade, the United States has seen rapid consolidation of health-care entities. Hospitals now own physician practices, insurers purchase pharmacy benefit managers and specialty pharmacies, and private-equity firms frequently acquire and later sell these assets to larger systems. 82 % of physicians are employed by hospitals, corporate insurers, or private-equity-backed entities, and UnitedHealth Group reported employing around 10,000 primary-care physicians in 2024, not counting its 80,000 “affiliated” physicians.
Regulatory oversight hinges on the 1976 Hart-Scott-Rodino Act, which requires reporting of mergers above a threshold that this year stands at $133.9 million. Many hospital-insurer deals exceed the threshold, while most physician-practice acquisitions fall below it, allowing consolidation to proceed with limited antitrust scrutiny.
Data and Statistics
- Physician employment: 82 % employed by hospitals or corporate entities.
- UnitedHealth staffing: ~10,000 primary-care physicians; 80,000 affiliated physicians.
- Merger reporting threshold (2025): $133.9 million.
- Study of 275 hospital-physician practice deals: 99 % below the reporting threshold.
- FTC enforcement (Trump administration, second term): 8 actions or suits against health-care mergers.
- Justice Department cases: 2, targeting hospital-insurer contracts.
- 2025 settlement with UnitedHealth’s $3.3 billion Amedisys acquisition: divestiture of 164 home-health and hospice locations.
- FTC settlement with Caremark (July): required greater transparency and patient choice; similar agreements reached with Express Scripts and pending with Optum.
Official Statements & Responses
Daniel Guarnera, director of the FTC’s Bureau of Competition, emphasized that “the FTC has made healthcare competition one of our top priorities.” He noted the agency relies heavily on complaints and news reports to identify smaller mergers that escape the reporting threshold.
Criticism & Opposition
Zack Cooper, an associate professor of public health and economics at Yale, warned that “antitrust laws aren’t fit for purpose at this point, and the agencies that enforce them are under-resourced.” He added that the primary gain was improved “operational throughput,” a financial metric rather than a clinical benefit.
Why It Matters
The consolidation of hospitals, insurers, physician practices, and pharmacies creates incentives for patients to receive care in higher-priced settings and to use insurer-mandated pharmacy networks, often without clinical justification. Proposed “site-neutral payment” policies—where providers receive the same reimbursement regardless of location—could mitigate forced referrals to costly venues, but such regulations remain under review by the White House’s Office of Management and Budget. As vertical integration expands, patients may face rising out-of-pocket costs and reduced autonomy in choosing where and how to receive care.
