Transition to Availity Essentials for enhanced self-service options

Starting August 20, 2025, the MHN provider portal at MHN.com (providers.mhn.com) and the email-based claims submissions on the Research and Review web page will no longer be available. To ensure seamless operations, we encourage you to transition to the Availity Essentials provider portal for your secure online self-service needs.

Why switch to Availity Essentials?

Availity Essentials brings a wide range of streamlined options to simplify your provider interactions, offering flexibility and real-time results. Key self-service features include:

  • Submit and track claims with up to 24 months of historical data available.
  • Modify and resubmit claims as needed.
  • Access detailed remittance data for easier reconciliation.
  • Check member benefits and eligibility details.
  • Submit initial prior authorization (PA) requests for Ambetter HMO/PPO, Employer Group HMO/POS, and Wellcare by Health Net members starting July 1, 2025, for select services.
  • For Medi-Cal providers, receive PCP notifications about member admission, discharge, and hospital transfers.
