California Governor Gavin Newsom has signed a pair of highly anticipated bills that will affect healthcare transactions involving private equity groups and hedge funds, effective January 1, 2026. The new legislation will expand the authority of the California Office of Health Care Affordability (“OHCA”) to review transactions previously excluded from reporting for their impact on healthcare costs and markets and will reinforce prohibitions on lay interference with the delivery of physician and dental services under the California’s corporate practice of medicine laws.

Last fall, private equity and hedge fund investors were given a reprieve from the prospect of increased oversight of healthcare transactions when California Governor Gavin Newsom unexpectedly vetoed Assembly Bill 3129 (AB 3129). That bill would have required review and approval by the California Attorney General of certain healthcare transactions involving private equity groups and hedge funds and imposed limitations on contractual relationships between investors and healthcare providers. On February 12, 2025, Senator Christopher Cabaldon (D-Sacramento) introduced Senate Bill 351 (SB 351), which revives aspects of AB 3129 relating to relationships between private equity groups and hedge funds and physician and dental practices, reinforcing California’s existing corporate practice of medicine and corporate practice of dentistry bars.

On August 31, the last day of its 2024 Legislative Session, the California Legislature approved Assembly Bill 3129 (Wood), which provides for notification to and review by the Attorney General of health care transactions involving private equity groups and hedge funds. This bill has been subject to intense lobbying, and its scope changed significantly in the month leading up to its passage. Governor Newsom is expected to sign the legislation in September. It is worth a comprehensive look at the final version of the bill, which will have a significant impact on future private equity transactions in California.

On May 16, 2024, the California Office of Health Care Affordability (“OHCA”) released proposed emergency regulations to update its existing rules for the reporting of certain health care transactions to OHCA for consideration of whether a Cost and Market Impact Review (“CMIR”) is warranted under the California Health Care Quality and Affordability Act. The current CMIR regulations became effective January 1, 2024, for transactions with a proposed closing date on or after April 1, 2024.

On November 28, 2023, the California Office of Health Care Affordability (“OHCA”) submitted proposed emergency regulations (the “Regulations”) on the reporting of certain transactions involving health care entities for review by the California Office of Administrative Law, the final step in the regulation process. The final Regulations, reflecting changes in response to public comments and those proposed by the Office of Administrative Law, were released on December 18, 2023, and will apply as of January 1, 2024, to covered transactions with a proposed closing date on or after April 1, 2024. Earlier articles covered the draft regulations and revised regulations, which parallels similar reporting regulations in nine other states, including Massachusetts, Washington, and Oregon. New York is proposing similar regulations for adoption in 2024.

This article will comment on the most recent changes to the Regulations and certain practical issues that must be considered in future transactions that will be subject to the reporting regime and cost and market impact reviews (“CMIR”).

In July of this year, the California Office of Health Care Affordability (“OHCA”) released draft regulations requiring the advance reporting of certain healthcare transactions that could affect the cost of healthcare or adversely impact the healthcare market in California. These reporting requirements implement provisions of amendments to the California Health and Safety Code enacted in 2022, which authorized OHCA to review proposed transactions and, if appropriate, undertake a detailed cost and market impact review (“CMIR”) to determine the potential impact on the health care economy of California.

On July 31, 2023, the California Office of Health Care Affordability (“OHCA”) released draft regulations concerning pre-transaction review of so-called “Material Change Transactions” as part of its legislative mandate to review transactions which could have potential impacts on the costs of health care in the State of California.  When approved, final regulations would be effective January 1, 2024. The draft regulations contemplate a dramatic expansion of state review of transactions affecting health care services.  The draft regulations are to be discussed at a public regulatory workshop to be convened by OHCA on August 15, 2023, at its Sacramento offices. OHCA will accept public comments on the draft regulations through August 31, 2023, submitted to CMIR@HCAI.CA.GOV.
