Medi-Cal Web Transaction Services Downtime Scheduled for January 2019

January 23, 2019

Required system upgrades to the California Medicaid Management Information System (CA-MMIS) are scheduled to take place on January 27, 2019. Upgrades begin during the regular daily maintenance period, which begins at midnight on Sunday, January 27, 2019, and continues through 5 a.m. During this window, Medi-Cal web transactions services 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 (SSA) 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.
