Pharmacy services; prohibit insurers and PBMs from requiring persons to obtain exclusively through pharmacies that they own.

HB 558 prohibits health insurers and pharmacy benefit managers (PBMs) from requiring patients to use only pharmacies they own for prescription drugs. It specifically bans insurers/PBMs from charging higher costs (like increased copays or deductibles) or offering lower reimbursements to independent pharmacies when patients choose them over insurer-owned pharmacies. The bill also prevents insurers/PBMs from denying preferred network status to independent pharmacies that agree to standard terms. This directly affects patients seeking pharmacy choice and independent pharmacies competing for reimbursement under health plans.
