N.Y. Workers' Comp. Law § 314
The right to compensation including medical care and funeral expenses under the provisions of this article shall be barred unless written claim is filed with the chairman within ninety days after injury or, if death results therefrom, within ninety days after death; except that if death shall occur more than one year after the injury, the right shall be barred unless prior written claim based on the injury has been timely filed. If disability or death is caused by a disease that is included among the diseases enumerated in section forty, then the claim may be filed within the time and in the manner provided in section forty.
Failure to file written claim as required may be excused by the chairman on the ground that, for good and sufficient reason, claim could not be filed on time.
