How to Access

To access InterWest's Workers Compensation network, carriers need to sign a Health Care Network Access Agreement. Carriers are welcome to use their own contract form if they prefer, as long as the language of the contract is consistent with the manner in which InterWest does business and the arrangements the company has with providers participating in the network.

Carriers who utilize the InterWest network are expected to:

  • Make reference to InterWest on Explanations of Review (EORs) as the WC network used to reprice claims
  • Designate an individual whom InterWest can contact for assistance in resolving EOR and other issues
  • Update the InterWest Provider Directory on a regular basis and stay current with negotiated rates
