Tennessee Code Title 71. Welfare § 71-6-117

(a) For purposes of this part, a person is not abused or neglected or in need of protective services if the person subject to care intentionally and willfully chooses or consents to engage in a religious method of healing in accordance with a recognized religious belief in lieu of medical treatment.

(b) This part does not require or authorize the provision of medical care to a terminally ill person if the person has executed an unrevoked living will in accordance with the Tennessee Right to Natural Death Act, compiled in title 32, chapter 11, and the provision of medical care would conflict with the terms of the living will.
