System Upgrade Scheduled for December 2018

December 10, 2018

Required system upgrades to the California Medicaid Management Information System (CA-MMIS) are scheduled to take place on December 16, 2018. Upgrades will begin during the regular daily maintenance period, which begins at midnight on Sunday, December 16, 2018 and will continue through 3 a.m.

During this window, the Medi-Cal website, Interactive Voice Response (IVR) System, telephone Automated Eligibility Verification System/Supplemental Automated Eligibility Verification System (AEVS/SAEVS) applications, Point of Service (POS) network and Provider Telecommunications Network (PTN) will be unavailable.

To reduce the impact on providers, upgrades are scheduled during a period when the systems are used less frequently.

A System Status Alert will be posted on the Medi-Cal website before the scheduled system upgrades. The alert will provide additional details, including the anticipated extended maintenance window timeframe.

Providers who subscribe to the Medi-Cal Subscription Service (MCSS) and select the “System Status Alert” option will receive an email notification when an alert is posted on the Medi-Cal website. Providers who have not yet subscribed are encouraged to do so by completing the MCSS Subscriber Form.
