Transition Information
MHN Transition to Health Net
Effective January 1, 2024, behavioral health services transitioned to Health Net of California, Inc. (Health Net) from MHN. Members did not experience any changes to their behavioral health benefits as a result of this change.
Medi-Cal Changes
As of January 1, 2024, California Health & Wellness Plan members in Amador, Calaveras, Inyo, Mono, and Tuolumne counties transitioned to Health Net Community Solutions, Inc., (Health Net) and members in Imperial County transitioned to Community Health Plan of the Imperial Valley (CHPIV). As a result of this transition, the administration of behavioral health services for these members also transitioned to Health Net.
Members who transitioned to Molina receive behavioral health benefits from Molina's behavioral health network and will not be managed by Health Net. For detailed information on the 2024 Medi-Cal Department of Health Care Services contract transition in Los Angeles County, refer to the 2024 DHCS Medi-Cal Transition – Health Net and Molina Healthcare membership-sharing Q&As. This resource provides helpful information on member transitions from Health Net to Molina.
