State Compliance

​We are committed to ensuring compliance with all state legislative and regulatory requirements related to the provision of pharmacy and ancillary services.

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 are a pharmacy who 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

If you are a pharmacy who 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

In accordance with requirements established by certain states, call 1-855-264-8815 with questions regarding MAC pricing.

Links to the MAC Inquiry Form and MAC Dispute Form are located at the bottom of this page, as is a Non-Disclosure Agreement. If you have general questions regarding our MAC pricing, please email us at

Step Therapy Law

In response to Kentucky Senate Bill 140 from 2022 (Acts Ch. 19), Optum Workers’ Compensation and Auto No-fault (Optum) notes that it has some standard point-of-sale adjudication processes in place with network pharmacies that may rely on certain step therapy recommendations. In doing so, Optum complies with relevant portions of amended KRS 304.17A-163. Optum processes workers’ compensation pharmacy transactions in Kentucky and complies with the medical treatment guidelines and pharmaceutical formulary as adopted by the Kentucky Department of Workers’ Claims.

Some of Optum’s insurer, self-insured employer and third-party administrator clients may also have custom step therapy protocols in place which differ from Optum’s standard point-of-sale adjudication processes. Optum does not handle step therapy exception requests or appeals for our clients, and health care professionals should contact the responsible insurer, self-insured employer or third-party administrator for more information on their specific exception request or appeal processes. Given this, reporting for those exception requests or appeals is also outside of the scope of Optum’s services as a workers’ compensation PBM. 

New York

Pharmacy ​network ​designation 

Pursuant to the New York State Workers’ Compensation Law and Regulations of the New York State Workers’ Compensation Board (NYS-WCB), a carrier or self-insured employer may designate one or more independent pharmacies, pharmacy chain, or pharmacy benefit manager for injured workers to obtain outpatient prescription medications.

For New York injured workers you can use our Tmesys retail pharmacy network and home delivery to provide pharmacy services. To ensure full compliance, as required, Tmesys files information with the NYS-WCB on a regular basis. Additionally, you can send notifications for utilizing a network pharmacy for work-related injuries to your employees. This notification includes information about participating network pharmacies and a locator tool for the Tmesys network. 

Under Board regulations, each pharmacy within the network is required to have a sufficient inventory so that it may service claimants without undue delay. Each designated pharmacy must also either be a remote pharmacy or be open for business hours that are regular and customary in the community.

More information on these pharmacy network programs, including specific regulatory compliance requirements, are contained in Chapter V of Title 12 NYCRR Subchapter M Part 440 of the New York Regulations.
