Any recipient receiving care in a nursing facility under this chapter, as part of a certified special treatment program for persons with mental illnesses, or as a part of a mental health therapeutic and rehabilitative program approved and certified by a local mental health director, is entitled to be temporarily absent from those facilities. The department may develop regulations establishing the periods of time and conditions under which temporary absences shall be permitted. These regulations shall require that absences be in accordance with an individual patient care plan and also provide for absences due to hospitalization for an acute condition. The limits on temporary leaves of absence established by the department by regulation shall not be less than 30 days per year.
During these temporary absences, the department shall reimburse the facility for the cost of maintaining the vacant accommodations at a rate to be determined by the department which shall be less than the normal reimbursement rate.
