Tennessee Code Title 34. Guardianship § 34-6-406

(a) A health care provider who has no actual knowledge of facts contrary to those stated in an authorization affidavit and who relies on a written instrument that is consistent with the requirements of this part and provides health care to an unemancipated minor shall not incur civil liability, criminal culpability, or professional disciplinary action for treating an unemancipated minor without legal consent if a reasonable health care provider would have relied on the written instrument under the same or similar circumstances. Nothing in this part requires a physician, dentist, mental health professional, or other health care provider to rely on a written instrument or to accept health care decisions from a person standing in loco parentis.

(b) An authorization affidavit does not confer dependency for health care coverage or insurance purposes.
