Cal. Welfare and Institutions Code § 14412

(a) The enrollment of a Medi-Cal beneficiary in the prepaid health plan shall not be terminated except for loss of eligibility, for good cause as determined by the department, or at the request of the beneficiary. (b) Enrollment shall be terminated at the request of the Medi-Cal beneficiary, to the extent required by federal law. (c) Any Medi-Cal beneficiary enrolled in a prepaid health plan who would remain eligible for Medi-Cal program benefits for three additional months pursuant to Section 14005.8 shall remain enrolled in the prepaid health plan and shall not receive a Medi-Cal card unless disenrollment is requested by the beneficiary, and the request is submitted in accordance with state and federal law. (d) It is the intent of the Legislature that the department shall develop such policies and procedures to maximize continuity of care for persons enrolled in prepaid health plans and to insure that the eligibility determination or redetermination process does not unnecessarily interfere with such enrollment or create gaps in the delivery of health services.
