Summary
California's Office of Health Care Affordability has issued draft regulations to implement AB 1415, legislation passed in fall 2025 that significantly expands regulatory oversight of private equity, hedge fund, and select management services organization transactions involving healthcare entities. The regulatory framework became effective January 1, 2026, requiring "noticing entities" to submit written notice to OHCA a minimum of 90 days before executing material transactions with covered healthcare providers.
The 90-day pre-transaction notice requirement represents a material operational constraint for deal execution in the California healthcare sector. Under the statute's framework, "material transactions" are defined broadly to encompass any transaction involving a sale, transfer, lease, exchange, option, encumbrance, or other conveyance of a material amount of healthcare entity assets, as well as any transaction that transfers control, responsibility, or governance of a material amount of assets or operations to one or more entities.
According to legal analysis from Polsinelli, the draft regulations expand OHCA's enforcement scope beyond the statutory language of AB 1415 itself. The firm noted that while the regulations implement the filing requirements established by statute, OHCA has used the regulatory process to revise additional requirements and procedures not explicitly captured in the legislation. This broader regulatory interpretation will capture a greater number of transactions throughout California, requiring investors to incorporate extended transaction timelines and comprehensive due diligence planning into deal structures.
Polsinelli characterized the initial regulatory draft as a "maximalist expansion" of OHCA's jurisdiction, suggesting the agency has interpreted its statutory mandate broadly. The firm expects further refinement and revision during the comment and finalization period, as the current draft contains language ambiguities and potential conflicts that will likely require resolution. For institutional investors and private equity managers focused on California healthcare acquisitions, the regulatory landscape now demands careful transaction structuring, extended planning horizons, and detailed engagement with state oversight mechanisms.
