  • The County has 45 days to process an application for Medi-Cal/CMSP. If the applicant requests a disability determination, the process may take up to 90 days depending upon how quickly the applicant provides information and the doctors and hospitals submit medical records.
  • If the applicant disagrees with any action taken by the County, there is an appeals process known as a State Hearing. Look on the back of the Notice of Action for information on how to request a State Hearing.
