Will Medi-Cal continue to accept non-standard and proprietary electronic claim formats after September 22, 2003?
Yes. Submitting claims using the new 837 4010A1 electronic format is not mandatory at this time. Providers who submit claims using Computer Media Claims (CMC) proprietary formats may continue to do so. However, there will be a phase-out period for non-standard and proprietary electronic claim formats in the future. Providers will be notified of the time frame for the phase-out period in a future Medi-Cal Update and on this Web site.
