Each adult day health care provider shall establish a grievance procedure under which participants may submit their grievances. Such procedure shall be approved by the department prior to the approval of the certification. The department shall establish standards for such procedures to insure adequate consideration and rectification of participant grievances. A provider shall make written findings of fact in the case of each grievance processed, a copy of which shall be transmitted to the participant. If the Medi-Cal participant has an unresolved grievance, the fair hearing provided in Chapter 7 (commencing with Section 10950) of Part 2 of this division shall be available to resolve all grievances regarding care and administration by the adult day health care provider. The findings and recommendations of the department, based on the decision of the hearing officer, shall be binding upon the adult day health care provider.
