CA-MMIS Upgrade November 6, 2016

November 2, 2016

Required systems upgrades to the California Medicaid Management Information System (CA-MMIS) are scheduled to take place during the first weekend of November. This is an upgrade of the hardware where many Medi-Cal services run. Upgrades will start during the regular daily maintenance period, which begins at midnight, and will continue through an extended maintenance window on November 6. During this window, providers will be unable to submit transactions.

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 the Friday 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.
