No pharmacy benefit manager shall prohibit or penalize a pharmacist or pharmacy from disclosing to an individual purchasing a prescription medication information regarding: the cost of the prescription medication to the individual, or the availability of any therapeutically equivalent alternative medications or alternative methods of purchasing the prescription medication, including but not limited to, paying a cash price; or charge or collect from an individual a copayment that exceeds the total submitted charges by the pharmacy for which the pharmacy is paid. If an individual pays a copayment, the pharmacy shall retain the adjudicated costs and the pharmacy benefit manager shall not redact or recoup the adjudicated cost.
