A pharmacy benefit manager may neither prohibit a pharmacist or pharmacy from, nor penalize a pharmacist or pharmacy for, informing a covered individual about:
(1) The cost of a prescription drug;
(2) The amount of reimbursement that the pharmacy will receive for dispensing the prescription drug;
(3) The cost and clinical efficacy of a more affordable alternative prescription drug, if one is available; and
(4) Any differential between the amount a covered individual would pay under the covered individual’s prescription drug benefit and a lower price the covered individual would pay for the prescription drug, if the covered individual obtained the prescription drug without making a claim for benefits on the covered individual’s prescription drug benefit.
