Tennessee Code Title 33. Mental Health and Substance Abuse and Intellectual and Developmental Disabilities § 33-8-202

(a) If a child with serious emotional disturbance or mental illness is sixteen (16) years of age or older, the child has the same rights as an adult with respect to outpatient and inpatient mental health treatment, medication decisions, confidential information, and participation in conflict resolution procedures under this title except as provided in part 3 of this chapter, or as otherwise expressly provided in this title. If the child's parent, legal guardian, legal custodian, or treating professional believes that the child's decision to terminate treatment, other than a request for discharge under chapter 6, part 2 of this title, will have severe adverse effects on the child, the conflict resolution procedures under chapter 2, part 6 of this title shall be used.

(b) An outpatient facility or professional may provide treatment and rehabilitation without obtaining the consent of the child's parent, legal guardian, or legal custodian.
