The decision of a caregiver to consent to or to refuse medical, dental, or mental health care for a minor child shall be superseded by any contravening decision of the parent having legal custody of the minor child; provided, however, that the decision of the parent does not jeopardize the life, health, or safety of the minor child. If at any time the parent or legal guardian disagrees with the decision of the caregiver or chooses to make any healthcare decisions for the minor child, then the parent must revoke the power of attorney for care of a minor child and provide the health care provider written documentation of the revocation.
