Illinois Enacts Legislation Enhancing Oversight of Private Equity Investments in Health Care

On August 7, 2026, Illinois became the latest state to tighten scrutiny of private equity in health care. Governor JB Pritzker signed House Bill 5000 (“HB 5000”) into law, amending the state’s existing health care transaction law framework (the “Prior Framework”)¹ to bring PE-backed deals more explicitly within its regulatory reach. Effective January 1, 2027, the law joins a growing wave of state-level action—including in Massachusetts and California—aimed at expanding oversight of PE investments in the health care industry.²

Key changes from the legislation are outlined below:

1. Expansion of Covered Transactions. Under the Prior Framework, a 30-day pre-closing notice to the state Office of the Attorney General was required for any merger, acquisition, or contracting affiliation between two or more health care facilities or provider organizations (together, also called “health care entities”). HB 5000 expands this requirement to require notice of transactions involving two or more health care facilities or provider organizations. This includes transactions where the parties to the transaction are entities that directly or indirectly own or control a health care facility or provider organization – “including if parties to the covered transaction are private equity companies.”

   The explicit reference to PE companies in the statutory text of HB 5000 signals the state’s increased focus on overseeing PE involvement in health care. “Private equity company” is broadly defined to mean any company that collects investments and owns (directly or indirectly, completely or partially) an ownership share of either (i) an Illinois health care entity or (ii) an out-of-state health care entity that generates at least $10 million from Illinois patients.

   Moving forward, PE investors transacting in the state should carefully review notice requirements under the Illinois health care transaction law. The breadth of this definition means that fund-level minority investments in health care portfolio companies may be captured, and PE sponsors should evaluate whether such transactions trigger notice obligations.

2. New Definitions. The Prior Framework defined “provider organization” as an entity “in the business of health care delivery or management that represents 20 or more health care providers in contracting with health carriers or third-party administrators for the payment of health care services.” However, it left the terms “health care provider” and “health care services” undefined, creating uncertainty about which providers and service types fell within scope.

   HB 5000 closes this gap by adding the following definitions:

   “Health care provider” means an individual or entity duly licensed or legally authorized to provide health care services.

   “Health care services” means health care services or products rendered or sold by a health care provider within the scope of the health care provider’s license or legal authorization. The term includes, but is not limited to, hospital, medical, surgical, dental, vision, and pharmaceutical services or products.

   These definitions materially expand the universe of entities potentially subject to review. The inclusion of pharmaceutical services or products and dental and vision services means that dental service organizations, pharmacy benefit management companies, and similar entities may now qualify as “provider organizations” if they represent 20 or more providers in payer contracting. Entities that previously concluded that they fell outside the Prior Framework’s reach should reassess their exposure.

3. Removal of Sunset Date. The Prior Framework included a January 1, 2027 sunset date, after which its requirements would automatically expire. HB 5000 eliminates this provision, establishing the health care transaction law as a permanent feature of Illinois’s regulatory landscape absent future legislative action to repeal or amend it.

***

HB 5000 represents a meaningful expansion of Illinois’s health care transaction oversight regime, consistent with a growing state-level trend toward PE-specific regulation. For PE sponsors, the law raises the stakes for transaction planning: broader notice triggers, an expansive definition of covered investors, and the removal of the sunset provision collectively signal that Illinois intends sustained, active oversight. Health care entities and investors transacting in Illinois should monitor implementation guidance from the Attorney General’s office and ensure they are prepared to comply before the January 1, 2027 effective date.
