Welf. & Inst. Code, § 14124.795

It is the intent of the Legislature to comply with federal law requiring that when a beneficiary has other available health coverage or insurance, the Medi-Cal program shall be the payer of last resort. Notwithstanding any other provision of law, any carrier described in Section 14124.70, including automobile, casualty, property, and malpractice insurers, shall enter into an agreement with the department to permit and assist the matching of the department’s Medi-Cal eligibility file against the carrier’s claim files, utilizing, if necessary, social security numbers as common identifiers for the purpose of determining whether Medi-Cal benefits were provided to a beneficiary because of an injury for which another person is liable, or for which a carrier is liable in accordance with the provisions of any policy of insurance. The carrier shall maintain a centralized file of claimants’ names, mailing addresses, and social security numbers or dates of birth. This information shall be made available to the department upon the department’s reasonable request. The agreement described in this section shall include financial arrangements for reimbursing carriers for necessary costs incurred in furnishing requested information.
