N.Y. Comp. Codes R. & Regs. tit. 11, § 217-1.2
(a) A claim for payment of medical or hospital services submitted on paper shall be deemed complete if it contains the minimum data elements set forth in this Part. If the minimum data elements set forth are not present or accurate, the payer may, but need not, adjudicate the claim if the payer can determine, based on the information submitted, whether such claim should be paid or denied. Even if the claim is deemed complete, a payer may, pursuant to the provision of section 3224-a(b) of the New York Insurance Law, request specific additional information, distinct from information on the claim form, necessary to make a determination as to its obligation to pay such claim.
(1) In the case of a medical claim submitted on the national standard form known as a CMS 1500 (previously known as HCFA 1500 [New York State]) and its successors, attached as an appendix, (see Appendix 26 of this Title), the claim shall contain at least the items in the following fields of the claim form, except as provided in paragraph (2) of this subdivision:
1a. Insured's I.D. Number
(b)
9. Other Insured's Name (if appropriate)
9a. Other Insured's Policy or Group Number (if appropriate)
9b. Other Insured's Date of Birth and Gender (if appropriate)

24F. $ Charges
24G. Days or Units (if appropriate)
33. Personal Identifying Number of the particular practitioner rendering the care plus, if practicing in a group, the Identifying Number of the group as well
(2) For items listed in paragraph (1) of this subdivision with the notation "(if appropriate)", the generic nature of the standard claim form produces some instances when the information is not relevant in a particular instance. In those cases, the payer shall not insist upon completion of that item if the information is not relevant to the situation of that particular practitioner or patient or the information will not be used by the payer. If an item is not applicable at all, it should be left blank rather than inserting a notation that it is not applicable.
(c)
84. Remarks (to report ZIP code for ambulance pick-up) (if appropriate)
