California Code, Welfare and Institutions Code - WIC § 14093.09

(a) No child in foster care shall be required to enroll in a Medi-Cal managed care plan. A foster child may be voluntarily enrolled in a Medi-Cal managed care plan only when the county child welfare agency with responsibility for the care and placement of the child, in consultation with the child's foster caregiver, determines that it is in the best interest of the child to do so and the department determines that enrollment is available to the child.

(b) Whenever a foster child is placed in an out-of-county placement, the county child welfare agency with responsibility for the care and placement of the child shall determine, in consultation with the child's foster caregiver, if the child should remain in, or has enrolled in, a Medi-Cal managed care plan in the county where the child will be placed or in the county with responsibility for the care and placement of the child, as long as the department determines that enrollment is available for the child.

(c) The State Department of Health Services shall establish for Medi-Cal managed care plans urgent disenrollment procedures that provide for disenrollment of foster children in out-of-county placements within two working days of receipt by the department's enrollment contractor, or the department, if the department has no enrollment contractor, of a request for disenrollment made by the child welfare services agency, the foster caregiver, or other person authorized to make medical decisions on behalf of the foster child.

(d) Medi-Cal managed care plans shall process and pay appropriately documented claims submitted by out-of-plan providers for services provided to foster children in out-of-county placements while they are Medi-Cal members of the plan. This section shall not be construed to prevent a plan from requiring prior authorization for nonemergency services consistent with the plan's established policies and procedures.
