Cal. Welf. & Inst. Code § 14008.7

If the applicant or beneficiary does not cooperate in the manner described in subdivisions (b) and (c) of Section 14008.6 to establish paternity and medical support orders against the noncustodial parents of each of the children for whom Medi-Cal services are requested or received, without good cause, as described in Section 11477.04, the applicant or beneficiary shall be ineligible for aid under this chapter or Chapter 8 (commencing with Section 14200). An applicant’s or beneficiary’s refusal to cooperate shall not effect the eligibility of the child or children. If otherwise eligible, the child or children may be granted Medi-Cal or continue to receive Medi-Cal.
