OH SB160

Health plan issuers are prohibited from making mid-plan-year changes to prescription drug coverage, including increasing cost-sharing, moving drugs to more restrictive formulary tiers, removing drugs from formularies, or adding prior authorization requirements

Drugs may only be removed from formularies mid-year if the FDA issues a safety warning, the manufacturer discontinues production, or the manufacturer removes the drug from U.S. sale

Insurers retain the right to require substitution of generic equivalents or interchangeable biological products, even when these become available during a plan year

Protections do not apply to drugs whose wholesale acquisition cost increases by more than 5% plus the rate of inflation compared to the previous plan year's average

Violations are classified as unfair and deceptive insurance practices under Ohio Revised Code section 3901.21
