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 disability insurers by the Department of Insurance. Existing law imposes various requirements and restrictions on health care service plans and disability insurers, including, among other things, a requirement that every group health care service plan contract or disability insurance policy that is issued, amended, or renewed on or after January 1, 1990, offer coverage for the treatment of infertility, except in vitro fertilization. This bill would require large and small group health care service plan contracts and disability insurance policies issued, amended, or renewed on or after July 1, 2025, to provide coverage for the diagnosis and treatment of infertility and fertility services. With respect to large group health care service plan contracts and disability insurance policies, the bill would require coverage for a maximum of 3 completed oocyte retrievals, as specified. The bill would revise the definition of infertility, and would remove the exclusion of in vitro fertilization from coverage. The bill would also delete a requirement that a health care service plan contract and disability insurance policy provide infertility treatment under agreed-upon terms that are communicated to all group contractholders and policyholders. The bill would prohibit a health care service plan or disability insurer from placing different conditions or coverage limitations on fertility medications or services, or the diagnosis and treatment of infertility and fertility services, than would apply to other conditions, as specified. The bill would make these requirements inapplicable to a religious employer, as defined, and specified contracts and policies. Because the violation of these provisions 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.
