No, Health Net and MHN are not exactly the same—but as of January 2024, all MHN behavioral health services are fully integrated into Health Net. If you’re a member or provider, this means you now access mental health and substance use services directly through Health Net, not MHN.
Understanding this change is important because it affects how you find behavioral health support, submit claims, and contact customer service. In this post, you’ll learn what happened, why the change occurred, and exactly what to do next. We’ll also answer common FAQs and link you to official Health Net resources.
What Was MHN? (Managed Health Network)
MHN, or Managed Health Network, was the behavioral health subsidiary of Health Net for decades. MHN administered all mental health and substance use disorder services for many Health Net plans, using its own provider portal, workflows, and branding.
- Services included: Therapy, psychiatry, addiction treatment, Employee Assistance Programs (EAPs), and crisis intervention.
- Who used MHN? Health Net members needing behavioral health or EAP services.
- How to access? Through the MHN portal, using MHN provider directories, and the MHN phone line.
Why Did Health Net and MHN Merge Branding ?
On January 1, 2024, Health Net announced that all behavioral health administration would transition from MHN’s platform to Health Net’s own systems and portals.
This change was made to streamline care, simplify access, and ensure consistency across all Health Net products (including Commercial, Medi-Cal, Medicare, and Ambetter plans).
- All new Health Net ID cards issued after January 1, 2024, dropped the MHN logo.
- All behavioral health services are now listed under “Health Net Behavioral Health.”
- The old MHN provider portal and processes were officially shut down by August 2025.
