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 generally prohibits a health care service plan, excluding a Medi-Cal managed care plan, or health insurer from subjecting antiretroviral drugs that are medically necessary for the prevention of HIV/AIDS, including preexposure prophylaxis or postexposure prophylaxis, to prior authorization or step therapy. Under existing law, a health care service plan or health insurer is not required to cover all of the therapeutically equivalent versions of those drugs without prior authorization or step therapy if at least one is covered without prior authorization or step therapy.
This bill would instead prohibit a health care service plan, excluding a Medi-Cal managed care plan, or health insurer from subjecting antiretroviral drugs, drug devices, or drug products that are medically necessary for the prevention of HIV/AIDS to prior authorization or step therapy. The bill would require a health care service plan contract or health insurance policy issued, amended, or renewed on or after January 1, 2027, that covers non-self-administered antiretroviral drugs, drug devices, or drug products that are approved by the United States Food and Drug Administration (FDA) for the prevention of HIV/AIDS as a medical benefit to also include those non-self-administered antiretroviral drugs, drug devices, or drug products as an outpatient prescription drug benefit. Because a willful violation of these provisions by a health care service plan would be a crime, this 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.
