AZ SB1413

Limits cost sharing for prescription insulin drugs to a maximum of $100 per 30-day supply across all health insurance plans (including medical service corporations, health care services organizations, disability insurers, blanket disability insurers, and accountable health plans).

Defines "prescription insulin drug" as any prescription medication prescribed by a health care professional to treat diabetes that contains insulin.

Applies the $100 cap regardless of the amount or type of insulin required to fill a subscriber's or enrollee's prescription.

Preserves insurers' ability to impose deductibles, coinsurance, and other cost sharing for diabetes equipment and supplies, with the insulin cost limit as the sole exception.

Amends six sections of Arizona Revised Statutes (20-826, 20-1057, 20-1342, 20-1402, 20-1404, and 20-2325) to implement consistent insulin cost-sharing restrictions across all health insurance product types.
