This section establishes an optional and nonexclusive procedure by which a patient or the patient's representative may exercise this right.
The physician shall document the basis for the DNR order or MOST in the patient's medical record. When the order is a MOST, the patient or the patient's representative must sign the form, provided, however, that if it is not practicable for the patient's representative to sign the original MOST form, the patient's representative shall sign a copy of the completed form and return it to the health care professional completing the form. The copy of the form with the signature of the patient's representative, whether in paper or electronic form, shall be placed in the patient's medical record. When the signature of the patient's representative is on a separate copy of the MOST form, the original MOST form must indicate in the appropriate signature field that the signature is "on file".
