(b) Where the attending physician or attending nurse practitioner has reason to believe that there is another parent or a non-custodial parent who has not been informed of a decision to issue an order not to resuscitate the minor, the attending physician or attending nurse practitioner, or someone acting on behalf of the attending physician or attending nurse practitioner, shall make reasonable efforts to determine if the uninformed parent or non-custodial parent has maintained substantial and continuous contact with the minor and, if so, shall make diligent efforts to notify that parent or non-custodial parent of the decision prior to issuing the order. 3. A parent or legal guardian may consent to an order not to resuscitate on behalf of a minor only if there has been a written determination by the attending physician or attending nurse practitioner, with the written concurrence of another physician or nurse practitioner selected by a person authorized by the hospital to make such selections given after personal examination of the patient, that, to a reasonable degree of medical certainty, the minor suffers from one of the medical conditions set forth in paragraph (c) of subdivision three of section twenty-nine hundred sixty-five of this article. Each determination shall be included in the patient's medical chart. 4. (a) A parent or legal guardian of a minor, in making a decision regarding cardiopulmonary resuscitation, shall consider the minor patient's wishes, including a consideration of the minor patient's religious and moral beliefs, and shall express a decision consenting to issuance of an order not to resuscitate either (i) in writing, dated and signed in the presence of one witness eighteen years of age or older who shall sign the decision, or (ii) orally, to two persons eighteen years of age or older, one of whom is a physician or nurse practitioner affiliated with the hospital in which the patient is being treated. Any such decision shall be recorded in the patient's medical chart.

(b) The attending physician or attending nurse practitioner who is provided with the decision of a minor's parent or legal guardian, expressed pursuant to this subdivision, and of the minor if the minor has capacity, shall include such decision or decisions in the minor's medical chart and shall comply with the provisions of paragraph (b) of subdivision four of section twenty-nine hundred sixty-five of this article.

(c) If the attending physician or attending nurse practitioner has actual notice of the opposition of a parent or non-custodial parent to consent by another parent to an order not to resuscitate a minor, the physician or nurse practitioner shall submit the matter to the dispute mediation system and such order shall not be issued or shall be revoked in accordance with the provisions of subdivision three of section twenty-nine hundred seventy-two of this article.
