The bill prohibits a health insurance carrier from excluding or limiting a drug under a health benefit plan and from moving the drug to a disadvantaged tier in the plan formulary if the drug was covered at the time the covered person enrolled in the plan. A carrier may not increase the amount that a covered person pays for a copayment, coinsurance, or deductible or set limits while the covered person is covered by the health benefit plan for drugs that were covered when the person became covered under the plan.
If a carrier uses a tiered plan, the carrier may not move a drug to a disadvantaged tier under specified circumstances.
A carrier may limit coverage for a drug or biosimilar product if a provider prescribes a generic drug or biosimilar product to treat the covered person's medical condition instead of the originally-prescribed drug and the covered person agrees.
