This Act authorizes a pharmacist or pharmacy to decline to dispense a prescription drug or provide a pharmacy service to an “insured” if the amount reimbursed by an entity subject to the Act is less than the pharmacy acquisition cost. This Act also prohibits a pharmacy benefits manager from reimbursing a pharmacist or pharmacy for a prescription drug or pharmacy service in an amount less than the pharmacy benefits manager reimburses itself or an affiliate for the same prescription drug or pharmacy service.
