If a conservatee requires medical treatment and the conservator has not been specifically authorized by the court to require the conservatee to receive medical treatment, the conservator shall, after notice to the conservatee, obtain a court order for that medical treatment, except in emergency cases in which the conservatee faces loss of life or serious bodily injury. The conservatee, if he or she chooses to contest the request for a court order, may petition the court for hearing which shall be held prior to granting the order.
