New York Claims Dispute & Statutory Guide

New York operates a statutory Workers' Compensation framework administered by the New York State Workers' Compensation Board (WCB) under Chapter 67 of the Consolidated Laws. Medical billing is strictly benchmarked to the Official New York State Workers' Compensation Medical Fee Schedule (12 NYCRR Part 329). Unpaid medical bill disputes are resolved administratively via Form HP-1 and Form HP-1J arbitration.
