Requires health care service plans and health insurers to apply third-party patient assistance program payments toward enrollees' or insureds' cost-sharing requirements (copayments, coinsurance, deductibles) for enrollees or insureds with chronic diseases or terminal illnesses, effective January 1, 2025.

Limits application to health care service plans and health insurance policies issued, amended, delivered, or renewed on or after January 1, 2025, and exempts self-insured ERISA plans and health savings account-qualified high deductible health plans until minimum deductibles are satisfied.

Requires health care service plans and health insurers to report by October 1 each year the 25 most frequently prescribed drugs and 25 most costly drugs with patient assistance programs, plus aggregate dollar amounts collected from third-party patient assistance programs attributable to drug utilization.

Mandates the Department of Managed Health Care and Department of Insurance to report by March 31, 2034 on the impact of these provisions on drug prices and health care premium rates, with a recommendation on whether to delete the January 1, 2035 repeal date.

All new cost-sharing provisions and expanded reporting requirements automatically repeal on January 1, 2035, with original reporting provisions resuming thereafter.
