How to Prepare Insurance Claim Documents for Faxing

This guide is for individuals sending paperwork for their own claim or helping a family member. Start with the request your insurer sent you: the documents and submission method depend on the policy, claim type and stage of the claim.

1. Identify what the insurer is asking for

First, decide whether you are reporting a new claim, providing information for an existing claim, correcting a document or appealing a decision. These tasks may use different forms and submission channels.

Check your insurer's letter, claim portal or current form for the document list, reference number, destination and deadline. A claims fax number should not be assumed to handle appeals, medical records or every insurance product.

Fax is one submission option where your insurer accepts it. Some insurers also provide a claim-specific upload link. For example, Progressive describes sending a link for sharing photos, videos and documents after a claim is reported. Use the channel specified for your case.

2. Gather the required documents

Use this table as an organizing checklist, then match it to your insurer's actual request.

For a property claim, supporting evidence may include an inventory, repair estimates and receipts. The NAIC's property-claim guidance recommends documenting losses and keeping receipts.

For a personal medical reimbursement claim, your plan may request a member claim form, itemized bills and receipts. As one specific example, the Aetna International claim form asks for those attachments, a signed authorization and the member ID on each submitted document. Follow your own plan's requirements rather than treating this example as a universal checklist.

If your insurer requests records you do not have, our medical records request checklist can help you prepare a request to the provider that holds them.

3. Make the packet easy to route

If your insurer supplies a required cover page, use it. Otherwise, a short cover sheet can tell the claims team what the packet contains and which file it belongs to.

Include the recipient or department, verified fax number, your name and callback details, the date, the claim reference if assigned, and the total page count including the cover sheet. Use the Fax.Plus cover sheet templates if you need a starting point.

Keep the subject brief and put detailed personal or medical information in the requested forms rather than repeating it on the cover sheet. A simple accompanying message could read:

Re: Claim [claim number], requested supporting documents
I am submitting the documents requested in your letter dated [date]: [document list]. This fax contains [number] pages, including this cover sheet. Please add these documents to the claim file. You can reach me at [callback number] if anything is missing or unreadable.

Where the insurer requests an identifier on each page, add it in a clear margin without covering text, signatures or barcodes. A cover sheet helps with routing; it does not replace the insurer's claim form or required authorization.

4. Create a clear, complete fax copy

For scanned paper documents

Scan every relevant side of each document. Keep pages upright, capture all edges and check small print at normal viewing size. Place small receipts on a plain full-size background so the details remain readable. Keep the originals.

Use the insurer's approved upload or other requested channel for original color photographs, videos or files whose detail needs to be preserved. Do not substitute a faxed image when the insurer asks for the original file.

For completed PDF forms

Save a separate copy for faxing with the filled fields and annotations fixed into the printable page. One practical method is to use Print → Save as PDF or Microsoft Print to PDF, then reopen the new file and check every answer and signature. Follow the Fax.Plus PDF preparation instructions.

Keep the original file too. If the insurer requires a verifiable digital signature or a particular signing process, follow that requirement before creating a fax copy; a printed signature image does not preserve the original file's digital verification.

5. Arrange and check the final packet

Follow any order the insurer specifies. Otherwise, a practical sequence is:

1. Cover sheet or accompanying note.
2. Insurer's reference page, if requested.
3. Completed claim form or response.
4. Supporting documents in the order listed in your note.

Review the assembled packet once more. Check the reference numbers, dates, required signatures, page orientation and total count. Remove accidental duplicates and unrelated pages while preserving everything the insurer requests.

If the packet exceeds a sending limit, ask the claims team how it wants the documents divided or submitted. Keep the claim reference and part numbering clear if it authorizes multiple transmissions.

6. Send with Fax.Plus and save your record

For occasional sending, our guide to sending a fax without a subscription explains the Free-plan allowance and prepaid credit options.

Once the packet is ready, open Fax.Plus, enter the verified recipient number with its country code, and attach the documents in the intended order. Review the destination and attachments before sending. Our guide to faxing a form covers the sending workflow.

Check that your packet fits your plan. On Free, the combined limit is 30 pages and 30 MB per fax, as described in the sending-limit instructions.

After sending, save the confirmation report from Sent alongside the exact packet you submitted. This gives you a useful record of the destination, transmission time and result. Use your claim portal or contact the claims team to check that the documents have been added to the correct file. See our fax confirmation guide for what the report establishes.
