(b) If an attending physician or attending nurse practitioner of a patient in a general hospital or mental hygiene facility determines that a patient lacks capacity because of mental illness, the attending physician or attending nurse practitioner who makes the determination must be, or must consult, for the purpose of confirming the determination, with a qualified psychiatrist. A record of such consultation shall be included in the patient's medical record.

(c) If the attending physician or attending nurse practitioner determines that a patient lacks capacity because of a developmental disability, the attending physician or attending nurse practitioner who makes the determination must be, or must consult, for the purpose of confirming the determination, with a physician, nurse practitioner or clinical psychologist who either is employed by a developmental disabilities services office named in section 13.17 of the mental hygiene law, or who has been employed for a minimum of two years to render care and service in a facility operated or licensed by the office for people with developmental disabilities, or has been approved by the commissioner of developmental disabilities in accordance with regulations promulgated by such commissioner. Such regulations shall require that a physician, nurse practitioner or clinical psychologist possess specialized training or three years experience in treating developmental disabilities. A record of such consultation shall be included in the patient's medical record.

(d) A physician or nurse practitioner who has been appointed as a patient's agent shall not make the determination of the patient's capacity to make health care decisions. 2. Request for a determination. If requested by the agent, an attending physician or attending nurse practitioner shall make a determination regarding the principal's capacity to make health care decisions for the purposes of this article. 3. Notice of determination. Notice of a determination that a principal lacks capacity to make health care decisions shall promptly be given: (a) to the principal, orally and in writing, where there is any indication of the principal's ability to comprehend such notice; (b) to the agent; (c) if the principal is in or is transferred from a mental hygiene facility, to the facility director; and (d) to the conservator for, or committee of, the principal. 4. Limited purpose of determination. A determination made pursuant to this section that a principal lacks capacity to make health care decisions shall not be construed as a finding that the patient lacks capacity for any other purpose. 5. Priority of principal's decision. Notwithstanding a determination pursuant to this section that the principal lacks capacity to make health care decisions, where a principal objects to the determination of incapacity or to a health care decision made by an agent, the principal's objection or decision shall prevail unless the principal is determined by a court of competent jurisdiction to lack capacity to make health care decisions. 6. Confirmation of lack of capacity. (a) The attending physician or attending nurse practitioner shall confirm the principal's continued incapacity before complying with an agent's health care decisions, other than those decisions made at or about the time of the initial determination made pursuant to subdivision one of this section.
