FTC and DOJ Finalize Heightened Antitrust Review Standards for Cross-Market Hospital Mergers

WASHINGTON — The Federal Trade Commission (FTC) and the Department of Justice (DOJ) Antitrust Division issued finalized joint merger enforcement guidelines on Monday, establishing heightened scrutiny and presumptive anti-competitive thresholds for cross-market hospital acquisitions, physician practice rollups, and private equity healthcare investments.

The regulatory framework, announced jointly by FTC Chair Lina Khan and Assistant Attorney General Jonathan Kanter, responds to extensive empirical healthcare economics data demonstrating that regional health system consolidations have consistently resulted in 15 to 25 percent increases in commercial inpatient and outpatient procedure prices without measurable improvements in clinical quality of care.

Targeting Serial Acquisitions and Cross-Market Leverage Under the new guidelines, antitrust enforcers will explicitly evaluate the cumulative impact of serial acquisitions—known as "roll-up" strategies—where private equity firms or regional health conglomerates purchase dozens of independent specialty clinics, outpatient surgery centers, and imaging practices below statutory Hart-Scott-Rodino filing thresholds.

"For decades, corporate healthcare consolidators have bypassed regulatory review by acquiring independent practices one at a time, eventually monopolizing regional provider markets and driving up insurance premiums for working families," FTC Chair Lina Khan said in Washington. "These finalized guidelines make clear that serial acquisitions designed to eliminate local competition will face aggressive federal antitrust challenges."

New Multi-Hospital Bargaining Thresholds The guidelines establish that cross-market mergers involving hospital systems operating in adjacent geographic areas will be evaluated for enhanced insurer bargaining leverage, anti-tiering contract clauses, and all-or-nothing contracting provisions that force employer-sponsored health plans to accept premium increases across entire networks.

Healthcare industry trade associations argued that hospital mergers are essential to maintaining financial stability for distressed rural facilities and integrating electronic health record systems. However, federal antitrust economists countered that preserving competitive labor markets for registered nurses and clinical specialists requires vigorous enforcement against monopsony employer power.

State attorneys general from twenty-four states announced plans to adopt the federal evidentiary standards in parallel state antitrust enforcement actions targeting localized clinical acquisitions.
