Workers’ Comp Fax Number: NY WCB and How to Find the Right Office
NY WCB publishes 877-533-0337 for centralized fax filings. Check the form’s permitted channel: CMS-1500 medical billing requires electronic submission.
There is no national workers’ comp fax number. Your state Board, insurer, employer and medical provider can each handle a different part of a claim. Match the recipient and the document before choosing a number.
New York’s Workers’ Compensation Board publishes 877-533-0337 for centralized document fax submissions. Its current form-specific rules still determine what you may fax. We checked the official sources on October 7, 2026; re-check the official page the day you send.
New York WCB: a published fax with form-specific limits
| Recipient | Published fax | Use |
|---|---|---|
| NY Workers’ Compensation Board, centralized document intake | 877-533-0337 | Send permitted Board documents |
The link opens the HIPAA flow because claim packets can contain medical information. Complete the BAA before uploading PHI. For an insurer’s request, confirm the insurer’s own destination; the Board fax does not automatically forward documents to your claims adjuster.
The Board’s Subject Number 046-909, issued in 2017, describes centralized fax intake and asks senders to use one submission method to avoid duplicates. Include the requested case identifiers, organize the pages and confirm that the document reached the case file. Check the latest form instructions before using this older general guidance.
CMS-1500 billing must follow the electronic process
The current CMS-1500 overview says treating providers must submit the universal medical billing form electronically through a Board-approved submission partner from August 1, 2025. A faxed copy does not replace that process.
This distinction matters: a Board contact fax can be valid while a particular billing form requires another channel. Providers should check the current electronic submission requirements, partner arrangements and acknowledgment process. Do not send a duplicate paper packet merely because a general fax number is available.
Find the recipient for your document
Read the request letter or current form first. Identify who needs the document and why:
- A Board filing goes through the Board’s permitted submission process.
- An insurer’s document request goes to the claims unit named in the request.
- Treatment authorization or medical billing may use a dedicated electronic workflow.
- An employer’s copy is separate when the instructions require it.
Ask the receiving office to confirm the destination if the letter and the public page disagree. Have the form name and case reference ready when you call. A third-party directory cannot tell you whether a particular form is accepted.
Prepare and send the packet
Use the current version of the form and complete the required signatures and dates. Place attachments in a clear sequence. Check that the case reference remains legible and that scans include all page edges. Keep an exact copy for your records.
For permitted fax submissions containing PHI, use SingleFax HIPAA fax, execute the electronic BAA and review the recipient and preview before sending. The flow shows its own price quote. A cover sheet should contain routing details and page count; keep clinical information in the required documents.
Save the receipt, then confirm acceptance with the relevant Board or insurer. Successful transmission does not establish a compensable claim, authorize treatment or guarantee payment. If the office requests another page, send the specific correction under its instructions rather than repeatedly sending the full packet.
