The following information outlines important facts that J8 providers should know about EDI and the J8 implementation:

    • Because you currently submit claims through one of the available NSVs, WPS is working with each NSV to :
      • Ensure there is no disruption in service to providers
      • Develop communications so that providers will know what to expect at cutover
    • As your current connectivity through an NSV will remain in place, connectivity via bulletin board system is not required.
    • You can use your current submitter IDs for J8

    • Electronic billers will not need to change their current connectivity to WPS
