Illinois proposes expanded healthcare transaction reporting: Implications for corporate practice of medicine and private equity structures

The Illinois General Assembly is considering legislation that would significantly expand the state’s healthcare transaction reporting requirements. While the proposed bills do not directly amend Illinois’ Corporate Practice of Medicine (CPOM) doctrine, they signal increased state scrutiny of healthcare ownership, private equity involvement, and control structures–areas closely intertwined with CPOM compliance.

If enacted, the legislation could meaningfully impact physician groups, management services organizations (MSOs), hospitals, private equity sponsors, and other healthcare investors operating in Illinois.

Current Illinois healthcare transaction reporting requirements

Under Illinois’ existing health care transaction reporting framework, codified in Section 7.2a of the Illinois Antitrust Act (740 ILCS 10/7.2a), certain healthcare facility and provider organization transactions must be reported to the Illinois Attorney General. The current law, which took effect on January 1, 2024, applies to mergers, acquisitions, and contracting affiliations between two or more healthcare facilities or provider organizations not previously under common ownership.

Section 7.2a defines “provider organization” as an entity or organized group of persons representing 20 or more healthcare providers in contracting with health carriers or third-party administrators for the payment of healthcare services. This definition includes various physician practices, physician-hospital organizations, independent practice associations, provider networks and accountable care organizations, keeping in mind the 20-provider threshold, which in some circumstances can be challenging to apply.

Parties to a covered transaction must provide written notice to the Attorney General at least 30 days prior to closing. The existing framework focuses on transactions directly between healthcare facilities or provider organizations rather than upstream ownership changes or transactions merely involving such entities. Importantly, the current reporting requirements are scheduled to sunset on January 1, 2027, unless extended by the legislature.

Overview of the proposed legislation

HB 5000/SB 3463

Introduced on February 4 and 5, 2026, respectively, these companion bills would amend Illinois’ healthcare transaction reporting law by broadening the scope of transactions subject to notice and review by the Illinois Attorney General.

Key proposed changes include:

• Expanding covered transactions from those occurring “between” healthcare facilities or provider organizations to those “involving” them
• Capturing transactions involving entities that own or control healthcare facilities or provider organizations
• Potentially bringing private equity sponsors and parent entities within the reporting framework
• Defining healthcare provider and healthcare services

The broadened “involving” language is particularly significant. It suggests the Attorney General could assert jurisdiction over upstream ownership transactions and restructuring activities that currently may not trigger reporting requirements.

Why this matters for CPOM compliance

The Corporate Practice of Medicine (CPOM) doctrine is a legal principle that prohibits corporations and other business entities from practicing medicine or employing physicians to provide medical services. The underlying policy rationale is to ensure that medical decisions are made by licensed physicians exercising independent professional judgment, free from commercial pressures or lay interference.

Illinois maintains a longstanding CPOM doctrine, under which non-physicians generally may not practice medicine or exercise control over physicians’ clinical judgment. Importantly, it limits who may own a physician practice or other regulated healthcare entity to licensed personnel, thereby prohibiting non-licensed individuals from participating in ownership. While CPOM in Illinois is grounded in case law and professional licensing statutes rather than a single comprehensive statute, it shapes how healthcare entities must structure:

• Physician ownership arrangements
• MSO management agreements
• Fee structures
• Governance rights
• Control provisions

Although HB 5000 and SB 3463 do not amend CPOM directly, they reflect a broader policy focus on:

• Private equity influence in healthcare
• Ownership transparency
• Consolidation and affiliation activity
• The allocation of control over healthcare entities

Expanded reporting authority could give the Attorney General greater visibility into MSO-physician structures and other arrangements frequently used to comply with CPOM while allowing outside investment.

Healthcare stakeholders should note that increased transparency often precedes increased regulatory scrutiny.

Potential impact on key stakeholders

Physician groups

Independent physician practices considering affiliation, recapitalization, or MSO arrangements may face additional reporting obligations, even if the transaction does not involve a traditional facility merger.

Private equity sponsors

Private equity sponsors acquiring upstream interests in holding companies that control physician entities may fall within the expanded definition of “covered transactions.” The proposed legislation explicitly defines a "private equity company" as an entity that pools capital and acquires ownership interests, directly or indirectly, in Illinois healthcare entities, as well as out-of-state healthcare entities that generate $10 million or more in annual revenue from patients residing in Illinois.

This could affect:

• Platform roll-ups
• Add-on acquisitions
• Internal restructurings
• Minority recapitalizations

MSOs and management companies

MSO arrangements, particularly those involving long-term management agreements and financial control provisions, may receive closer regulatory attention if ownership changes trigger reporting requirements.

Hospitals and health systems

Affiliation agreements and joint ventures that previously fell outside the reporting framework may now require pre-transaction notice.

Broader national context

Illinois’ proposal aligns with a broader national trend of states increasing oversight of healthcare consolidation and private equity involvement in healthcare. Across multiple jurisdictions, legislatures and attorneys general have:

• Expanded transaction review statutes
• Lowered reporting thresholds
• Enhanced enforcement authority
• Examined MSO and physician control structures

Even where CPOM doctrine remains unchanged, states are leveraging transaction reporting laws as a regulatory entry point into ownership and control arrangements.

Practical considerations

Healthcare organizations and investors should begin evaluating:

1. Whether pending or planned 2026 transactions could trigger expanded reporting
2. How ownership and control structures are documented
3. Governance provisions that may attract regulatory scrutiny
4. MSO agreements and management fee arrangements
5. Transaction timelines in light of potential 30-day pre-closing notice requirements

Because the bills remain pending and it is early in the legislative session, prospects for passage remain uncertain. Stakeholders should monitor legislative developments closely. Notably, if either bill is enacted, the January 1, 2027, sunset date that currently applies to the reporting framework would be removed, extending the requirements, perhaps indefinitely. Implementing regulations or guidance from the Illinois Attorney General’s Office may also follow.

What to watch next

• Committee movement and amendments in the Illinois General Assembly
• Clarification of how “involving” will be interpreted
• Whether additional CPOM-related reforms are introduced
• Enforcement posture statements from the Illinois Attorney General’s Office

Expanded transaction review authority, even absent direct CPOM reform, may meaningfully shift the regulatory landscape for physician ownership and healthcare investment structures in Illinois.

The bottom line

HB 5000 and SB 3463 signal heightened scrutiny of healthcare ownership and control structures in Illinois. While the state’s CPOM doctrine remains intact, the proposed expansion of healthcare transaction reporting could increase oversight of MSO arrangements, private equity investments, and physician group affiliations. Given the early stage of the legislative session, prospects for passage remain uncertain, and the bills may be subject to significant amendment.

Healthcare providers, investors, and management entities should evaluate their transaction pipelines and governance structures in anticipation of potential regulatory changes.
