Important updates to HWMG’s Administrative Manual for Participating Providers
This notice is to advise you of updates to our Administrative Manual for Participating Providers effective June 1, 2020, which amends certain terms of your Participating Provider Agreement. HWMG is the third-party administrator and local provider network for HMAA and self-insured clients.

This manual is for all provider types and specialties. Changes from the prior version include the following:
  • Modifications to the Credentialing and Recredentialing Process to streamline recredentialing.

  • Modifications to Requests for Reconsideration related to utilization review denials for medical services and prescription drugs.

  • Modified deadline in Dispute Resolution to dispute a determination related to administrative matters. We have also added the option to submit requests using our appeal request form.

  • Other administrative changes for clarity and consistency.

To obtain the most up-to-date version of our Administrative Manual and precertification forms, please visit our website at hwmg.org/providers , or contact us to obtain a copy. Should you have any questions, please feel free to contact us Monday through Friday, 8 am to 4 pm HST. Mahalo for your support and continued participation!
