SB 61 prohibits a health plan issuer from imposing – on a prescription insulin drug – cost sharing in an amount that exceeds $35 for a 30-day supply. The prohibition applies as follows: (1) only to health plan issuers that provide coverage for prescription insulin drugs and (2) regardless of the amount or type of insulin needed to fill a covered person’s prescription. Under the bill, cost sharing must be charged on a per-prescription-fill basis.
