SB 40: Health care coverage: insulin.

The bill aims to improve health care coverage by regulating insulin costs. It prohibits health care service plans and insurance policies from imposing copays, coinsurance, or deductibles higher than $35 for a 30-day supply of insulin, unless it is medically necessary. Starting in 2026, health care service plans and insurance policies cannot impose step therapy as a prerequisite for insulin coverage. Large group plans must include at least one insulin form in each drug type in their formulary. The $35 cap can be higher for tier 3 insulin if the formulary is grouped into tiers. Additionally, the bill requires reimbursement for costs mandated by the state, but excludes reimbursement for certain costs.
