System Upgrades Scheduled for December 2019

Required system upgrades to the California Medicaid Management Information System (MMIS) are scheduled to take place on December 8, 2019. Upgrades will begin during an extended maintenance period, which begins at midnight on Sunday, December 8, 2019, and will continue through 9:30 a.m. The following may not be available during this window:

    Point of Service (POS) network leased line pharmacy transactions that require a Treatment Authorization Request (TAR)
    POS network leased line prior authorization transactions
    Pharmacy TAR (PTAR) and electronic TAR (eTAR) transactions through the Transaction Services area of the Medi-Cal website and Provider Telecommunications Network (PTN) transactions

Other applications may also be affected. To reduce the impact on providers, upgrades are scheduled during a period when the systems are used less frequently.


CA-MMIS Network Outage

The Medi-Cal website, website applications and transactions, have been affected by a temporary network outage that may impact providers using various CA-MMIS systems. We are working to resolve this problem as soon as possible. Please refer to this website for updates and problem resolution.
