UnitedHealth's Ambitious Acquisition Threatens Medicare Advantage Competition

Thesis
A Dangerous Consolidation of Power
UnitedHealth Group’s proposed acquisition of Amedisys represents a dangerous consolidation of power in the Medicare Advantage market, one that threatens to stifle competition and harm patients. This deal, if approved, would further entrench UnitedHealth’s dominance in a system already rife with anti-competitive practices. The federal government must intervene to block this merger, preserving what little competition remains in a sector increasingly controlled by a handful of corporate giants.
Evidence
The Growing Monopoly in Medicare Advantage
UnitedHealth, already the largest player in Medicare Advantage, has systematically expanded its reach through acquisitions and vertical integration. The Amedisys deal would give it control over a significant portion of home health services, a critical component of patient care. According to STAT News (2025-08-11T16:54:19+00:00), this move follows a pattern of aggressive consolidation that has drawn scrutiny from antitrust regulators.
UnitedHealth’s Optum division already owns physician groups, surgery centers, and pharmacy benefit managers. Adding Amedisys’s home health services would create a near-monopoly in some regions, leaving patients with fewer choices and higher costs. The company’s own filings show its Medicare Advantage enrollment has grown by double digits annually, further squeezing out smaller competitors.
Counterpoint
The Efficiency Argument
Proponents of the merger argue that consolidation improves efficiency, reducing administrative overhead and streamlining care. They claim that integrated systems like UnitedHealth’s can deliver better outcomes at lower costs, benefiting both patients and taxpayers. Some industry analysts, including those cited in the STAT News report, suggest that blocking the deal could disrupt care coordination and slow innovation in home health services.
Rebuttal
Efficiency at What Cost?
While efficiency gains sound appealing, they often come at the expense of competition—and ultimately, patients. Research from the American Economic Review shows that hospital mergers, for example, frequently lead to higher prices without measurable improvements in care quality. UnitedHealth’s track record suggests a similar outcome: its growing market share has coincided with rising premiums and narrower provider networks.
The idea that monopolies drive innovation is a myth. True innovation thrives in competitive markets, where multiple players vie to improve services. UnitedHealth’s dominance risks creating a stagnant system where patients have no alternatives when care quality declines.
Implications
A System on the Brink
If this merger proceeds, it will set a dangerous precedent for further consolidation in health care. Smaller providers will struggle to compete, and regional monopolies could become the norm. Patients, particularly seniors reliant on Medicare Advantage, will face fewer choices and less leverage over their care.
The stakes extend beyond this single deal. The Biden administration has made antitrust enforcement a priority, but this case will test its resolve. Allowing UnitedHealth to absorb Amedisys would signal open season for further acquisitions, eroding what remains of competition in health care.
Recommendations
How to Stop the Bleeding
First, the Federal Trade Commission must block this merger outright. The combined entity’s market share in key regions would violate antitrust guidelines, and regulators should act decisively.
Second, Congress should revisit Medicare Advantage payment structures to discourage consolidation. Current reimbursement rates incentivize large insurers to dominate markets rather than compete on quality.
Finally, states should strengthen oversight of vertical integration in health care. California’s recent laws limiting insurer-owned provider networks offer a model for other states to follow.
The time to act is now. Once competition vanishes, it rarely returns.
