Hospital Mergers & Acquisitions: Hospital Acquisition Due Diligence

The FTC and DOJ define the relevant geographic market by examining patient flow and referral patterns, not by administrative or political boundaries. A hospital in Queens may compete primarily with facilities within a 15-mile radius, or the market may extend further depending on specialty services and insurer networks. Courts have repeatedly held that hospitals cannot easily divert patients across long distances, which means local concentration matters far more than national scale. If the transaction significantly increases concentration in the relevant market, regulators will demand proof that efficiencies or other factors outweigh the competitive harm.

Parties often argue that consolidation will reduce duplicate services, improve supply chain management, and generate clinical synergies that benefit patients. Yet courts require that these efficiencies be merger-specific (achievable only through the transaction, not through less restrictive alternatives), quantifiable, and timely. In practice, efficiency claims rarely overcome a strong presumption of anticompetitive harm in a concentrated market. The burden is on the hospital defendants to prove that benefits will materialize, not on the FTC to disprove them.

In New York, a hospital merger typically triggers Department of Health review under Public Health Law Article 28. The agency examines the transaction's impact on access, quality, financial stability, and service availability in the affected regions. This review is separate from antitrust analysis and focuses on state-level public health policy rather than competition law. Parties must demonstrate that the combined entity will maintain or enhance service quality and access, particularly for vulnerable populations and safety-net services.

If the transaction involves significant capital investment, facility changes, or service relocations, CON approval becomes mandatory. The CON process requires submission of detailed documentation showing need, financial feasibility, and community benefit. Delays in CON review can extend transaction timelines by many months. Experienced healthcare counsel coordinates CON filings with antitrust strategy to ensure consistency across regulatory submissions.

Hospitals depend on Medicare and Medicaid reimbursement for a substantial portion of revenue. Any history of billing errors, coding violations, or compliance program deficiencies can expose the acquiring entity to liability. From a practitioner's perspective, the acquiring hospital inherits compliance risk unless the purchase agreement explicitly allocates liability to the seller or establishes escrow for indemnification claims. A single qui tam suit under the False Claims Act can result in treble damages and civil penalties, so careful compliance review and representation and warranty insurance are essential safeguards.

Hospital medical staffs operate under bylaws that govern credentialing, privileging, and peer review. A merger may trigger medical staff concerns about changes in governance, clinical decision-making, or employment terms. Physician employment arrangements, call schedules, and compensation models must be reviewed to identify contracts that terminate upon change of control or require renegotiation. These issues are often contested in litigation if physicians challenge the merger or feel disadvantaged by post-closing integration.
