Quick answers

Did CA AB 539 pass?

No. CA AB 539 passed the legislature but was vetoed. Latest recorded action (2026-09-20): Vetoed by Governor.

What is CA AB 539 about?

Existing law, the Knox-Keene Health Care Service Plan Act of 1975, provides for the licensure and regulation of health care service plans by the Department of Managed Health Care and makes a willful violation of the act a crime. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing law provides that a health care service plan or a health insurer that authorizes a specific type of treatment by a health care provider shall not rescind or modify this authorization after the provider renders the health care service in good faith and pursuant to the authorization. This bill would require an approved prior authorization for a health care service requested by an in-network provider to remain valid for at least one year from the date of approval, or the period requested by the treating provider if less than one year. Because a violation of the bill by a health care service plan would be a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
