Medi-Cal eligibility must be renewed at least once every twelve months. However, certain circumstances may require individuals to report changes in their situation sooner. For example, if a person's income, household size, or residency status changes, they should report these changes as they may affect eligibility. Additionally, some individuals may qualify for "continuous eligibility," which allows coverage to continue without annual renewal for a set period. It is important for beneficiaries to stay informed about their renewal dates and to respond promptly to any notifications from the California Department of Health Care Services regarding their eligibility status. For detailed information about renewal processes and timelines, it is beneficial to visit the official Medi-Cal website, where one can find valuable resources and guidance.
