Summary

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's requirements a crime. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing law sets forth specified coverage requirements for plan contracts and insurance policies, and limits the copayment, coinsurance, deductible, and other cost sharing that may be imposed for specified health care services. This bill would require a large group health care service plan contract or large group health insurance policy, except a specialized health care service plan contract or health insurance policy, that is issued, amended, or renewed on or after January 1, 2026, to include coverage for one portable high-efficiency particulate air (HEPA) purifier for an enrollee or insured who is pregnant or diagnosed with asthma or chronic obstructive pulmonary disease if the enrollee or insured is residing in or displaced from a county where a local or state emergency has been declared due to wildfires and the HEPA purifier is prescribed by the enrollee's or insured's health care provider. The bill would prohibit the cost of the HEPA purifier from exceeding $500, adjusted for inflation, as specified. 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. This bill would declare that it is to take effect immediately as an urgency statute.
