(a) Any physician, dentist, or other health care provider involved in the health care of a minor child may rely upon the authority of the agent named in a signed and acknowledged authorization to consent to health care for minor in the absence of actual knowledge that the authorization has been revoked or is otherwise invalid.
(b) Any consent to health care for a minor child given by an agent pursuant to an authorization to consent to health care for minor shall have the same effect as if the custodial parent making the authorization were present and acting on behalf of the parent's minor child. Any physician, dentist, or other health care provider relying in good faith on the authority of an agent shall be protected to the full extent of the power conferred upon the agent, and no person so relying on the authority of the agent shall be liable, by reason of reliance, for actions taken pursuant to a consent of the agent. (1993, c. 150, s. 1.)
