Missouri Revised Statutes Title XIII. Correctional and Penal Institutions § 219.066. Medical and dental treatment authorized, when

1. Except in case of emergency, the division shall not authorize or permit any major surgery to be performed upon or general anesthetic to be administered to any child committed to the division unless specific written consent thereto shall first have been obtained from the parent or guardian of such child, or, in the absence of such consent, from the court which vested legal custody of such child in the division or any court that has jurisdiction.

2. Upon the recommendation of an attending physician, psychiatrist, surgeon or dentist, the division may authorize medical, psychiatric, surgical, or dental care and treatment as may be required by the child. If the care and treatment is contrary to the religious tenets and beliefs of such child, the treatment of the child may be authorized by the division only upon the specific written consent of the parent or guardian of the child, or, in the absence of such consent, upon the specific written order of the court which vested legal custody of the child in the division or any court that has jurisdiction.

3. When the child has been placed by the division in a residential child caring facility, other than one administered by the division, the person or persons administering such facility shall have the authority to provide the child with necessary medical, psychiatric, surgical, or dental care only to the extent that such authority has been delegated to such persons with respect to particular children and subject to the same limitations as are applicable to the division under sections 219.011 to 219.086.
