For the longest time, NY required it’s unique form (the C4) for claims submission (by mail only). As of 2019, they are now permitting the standard HCFA 1500 to be used, along with a Narrative component. We have done the necessary crosswalk from the C4 to the 1500, and enlarged the Accident Description area for your Narrative. Only use the Accident Description if you are planning to send the claim electronically, and the information will be automatically added to the electronic claim.
