The process

  • An eligibility worker (EW) will be assigned to process each application. If additional documents or proof of circumstances are needed, the EW will request them via mail.
  • The applicant will receive a letter, called a Notice of Action, letting him/her know if benefits have been approved or denied.
  • 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.
