Maximum Allowable Cost (MAC)
To assure the Maximum Allowable Cost (MAC) list accurately reflects market pricing and the availability of generic medications, Optum utilizes multiple sources to determine MAC pricing. The sources include de-identified market pricing benchmark data such as AWP and WAC, wholesaler information on market availability, and pharmacy information from inquiries.
The following states have passed legislation requiring workers’ compensation pharmacy benefit managers (PBMs) to provide a process for pharmacies to make an inquiry about MAC pricing for a specific medication and to provide for an appeals process: Arizona, Arkansas, Delaware, Georgia, Idaho, Kentucky, Louisiana, Maine, Minnesota, Mississippi, Montana, New Mexico, New York, Oklahoma, and Vermont.
If you represent a pharmacy that would like to receive information regarding our MAC pricing for a specific medication, please complete the MAC Inquiry form, along with a signed non-disclosure agreement, and email the documents to MACresolution@optum.com.
If you represent a pharmacy that would like to file an appeal or otherwise dispute our MAC pricing for a specific medication, please complete the MAC Dispute form along with a signed non-disclosure agreement, and email the documents to MACresolution@optum.com.
In accordance with requirements established by certain states, call 1-855-264-8815 with questions regarding MAC pricing.
