WSI offers several options for submitting a request for medications, which require prior authorization. A provider should refer to the WSI Formulary/Medication Restrictions list to identify which medications require prior authorization.
To request prior authorization of a medication, a provider may select one of the following options:
- Contact WSI Customer Service at 701-328-3800 or 800-777-5033 to speak with a pharmacy technician
- Obtain the Provider’s Request for Medication Prior Authorization (M11) form from the WSI website and fax to 888-786-8695
- Utilize CoverMyMeds® to submit a request to WSI
WSI requires supporting medical documentation for authorization of certain medications, e.g. brand name medications. Once WSI receives and reviews all of the necessary information, the requesting party will receive notification of the authorization status.
