From the NYS Workers' Compensation Board:
Effective May 2, 2022, Board-authorized and out-of-state health care providers must submit all Prior Authorization Requests (PAR) through OnBoard, which will automatically route the request to the appropriate claim administrator for review. Paper forms can no longer be faxed, emailed, or mailed directly to NYSIF for approval. The type of PAR a health care provider can submit varies by profession and is outlined on the Board's website.
