SB 1309 California Senate · 2025-2026 Regular Session

Health care coverage: lung cancer.

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 a crime. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing law requires a health care service plan contract or health insurance policy to provide coverage for all generally medically accepted cancer screening tests. This bill would require a health care service plan contract or health insurance policy, except as specified, that is issued, amended, or renewed on or after January 1, 2027, to provide coverage for followup screening or diagnostic services for lung cancer, as specified. The bill would prohibit a contract or policy from imposing a copayment, coinsurance, deductible, or any other form of cost sharing for this coverage. If a health care service plan contract or health insurance policy is a high deductible health plan, the bill would prohibit the contract or policy from imposing a deductible, coinsurance, or any other cost sharing on this coverage unless not imposing the deductible, coinsurance, or cost sharing would conflict with the federal requirements for high deductible health plans. Because a willful 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.
