Certain services, including Durable Medical Equipment, require approval from either the claims adjuster or the Utilization Review department as outlined in the Utilization Review Guide. Failure to obtain prior authorization may result in WSI not providing coverage for the service.  Prior authorization approval is not a guarantee of payment; reimbursement is dependent upon the final liability determination of the claim.

Submitting a Prior Authorization Request

The Post Injection Pain Response form is a tool for providers to utilize when requesting authorization for additional injections. The form contains pertinent information WSI requires for additional injections. The intent of the Post Injection Pain Response form is to supplement the documentation. Its use is not mandatory and it does not replace the UR-C form.

Submitting a Retrospective Authorization Review Request

  • Review the Utilization Review Guide to determine if prior authorization is required
  • Submit a bill for processing if prior authorization was deemed necessary
  • Complete the Medical Bill Appeal (M6) form upon receipt of a denied charge, which will initiate the retrospective authorization review process
  • Fax the M6 form and supporting documentation to: 701-328-3765 or 866-356-6433

Criteria for a Retrospective Authorization Review

WSI will allow a retrospective authorization review if the provider can demonstrate one of the following:
  • Provider was not aware the condition was, or likely would be, covered by WSI
  • Injured worker's claim status on date of service included: denied, presumed closed, or a claim not filed
