Utilization Reviews (UR)

What is Utilization Review (UR)?

The utilization review process compares requests for medical services ("utilization") to treatment guidelines that are deemed appropriate for such services and includes the preparation of a recommendation based on that comparison. The Utilization Review Program applies only to claims that are adjudicated by the State Fund. The program applies to both physicians and facilities. L&I contracts with Comagine Health for Utilization Review. 


The utilization review process supports the agency's mission to purchase only proper and necessary care for injured workers.

Criteria used for review

Comagine Health uses the Department's Medical Treatment Guidelines.

  • When there are no Department Medical Treatment Guidelines available, Comagine Health utilizes InterQual criteria.
  • Initial clinical review is conducted by a registered nurse or therapist
    • does not meet guidelines or criteria, referred for physician review
    • physician reviewer unable to recommend approval
      • requesting physician has the opportunity to discuss the case
  • Comagine Health recommendations are sent to the L&I claim managers.
    • The claim manager will review the information and recommendation made by Comagine Health and will then decide whether to authorize or deny the request.
    • The claim manager will issue the final determination and inform the requesting provider.

Non-initiated claims

Comagine Health will review requests for treatment or procedures on non-initiated claims in the same manner as initiated claims.

  • Physicians and facilities must follow the same UR process, however, L&I's determination will be delayed until the claim has been initiated and assigned to a claim manager.
  • Decisions to proceed with appropriate medical care should be based on the providers' best clinical judgment and not on the status of the request.

UR Simplification (Group A Provider)

Those providers with 100% UR approval recommendations when they performed 10 or more reviews during the one year review period may be eligible to become a Group A Provider.

  • monitor's their quality of reviews.

Comagine Health, L&I's contracted UR vendor:

  • Review cases against L&I's Medical Treatment Guidelines or InterQual criteria, and
