In our efforts to continue to collaborate on the delivery of quality healthcare to our Members, we hereby inform you of the revised OptumRx Provider Manual ("Manual"), which replaces andsupersedes the previous versions of OptumRx’s and Catamaran’s respective manuals, and is now available at the following location:

The Manual is incorporated into your pharmacy agreement(s) with OptumRx and Catamaran. Whether you are contracted directly or indirectly through a PSAO or chain, as a participating network pharmacy provider you are responsible for understanding and complying with all of the Manual’s terms and conditions. Failure to comply with the Agreement and Manual may result in disciplinary action, up to and including termination from all pharmacy networks. Network pharmacy providers shall routinely consult the Manual to ensure compliance.

OptumRx will continue to require pharmacies meet specific credentialing requirements. Catamaran previously communicated these requirements beginning in 2014, however as you are aware, Catamaran was acquired by OptumRx in July 2015 and as a result, the new entity is now communicating the requirement will be continued with the new combined organization.

Beginning January 1, 2016, several updates will be made to our pharmacy benefits. UnitedHealthcare seeks to make prescription drugs and supplies accessible and affordable to members through our Prescription Drug List (PDL) and benefit programs.The tables below provide a summary of these changes as well as a list of alternatives.
