# Mail a health insurance claim packet online

Use Health Insurance Claim Packets when you need more than a generic PDF upload. It helps you turn a reimbursement claim, mailed supporting-document packet, or claim reprocessing follow-up into a clean packet with a cover page, claim letter, summary page, exhibit index, and supporting records in print order.

## How it works
1. **Choose the packet type** - Start with Health Insurance Claim Packets and select whether this is a new claim, requested-document packet, reprocessing request, or accident or COB follow-up.
2. **Enter the claim details** - Add the patient, member ID, provider, service dates, claim number, and the short summary you want the payer to read first.
3. **Upload the exhibits** - Attach the claim form and any supporting bills, EOBs, records, or payer letters.
4. **Review before mailing** - PostalForm generates the final packet PDF so you can confirm the cover page, claim letter, summary, exhibit order, and mailing details before checkout.


## Use this workflow when
- A payer asked you to mail a claim form, bills, and records instead of uploading them in a portal.
- You are filing an out-of-network reimbursement claim and want the packet organized before mailing.
- The insurer asked for more documents after the initial filing.
- You need to mail a reprocessing or accident or coordination-of-benefits follow-up tied to a specific member and claim.

## What the workflow builds
- Cover page with the packet type, member, payer, provider, and enclosed exhibits.
- Main claim letter that explains what the packet is for and what action you want from the payer.
- Claim summary page with the member details, service dates, sender details, and mailing context.
- Exhibit index so the packet reads like one organized submission instead of a loose stack of scans.

## What to include
- The completed claim form, reimbursement form, or insurer packet.
- Itemized bills, receipts, or provider statements.
- EOBs, denial letters, or request-for-information letters when relevant.
- Medical records, referrals, or payer correspondence if the insurer asked for them.

## Why this converts better than a generic upload flow
Searchers looking for a health insurance claim packet, mailed reimbursement claim packet, or mail health insurance claim online usually do not want to assemble the packet manually. They need the filing to feel organized and credible. [Health Insurance Claim Packets](/forms/health-insurance-claim-packets) gives them that structure without needing to merge pages, write a cover letter from scratch, or guess at packet order.

## Avoid delays
- Mail to the claims or document-review address the payer gave you, not a general customer-service address.
- Keep the member ID, claim number, and service dates visible in the packet summary.
- Attach copies, not originals, unless the payer explicitly asks for originals.
- Review the final PDF before mailing so the cover letter and exhibit order match the actual packet.


## FAQs
- **Can I use this for out-of-network reimbursement claims?** Yes. The workflow is built for reimbursement claim packets, mailed supporting-document packets, and claim follow-ups.
- **Can I attach multiple supporting PDFs?** Yes. Upload the claim form plus bills, EOBs, letters, and other records, and the packet builder will append them behind the generated letter and summary pages.
- **Will I see the packet before checkout?** Yes. The preview is part of the flow so you can review the assembled packet before mailing.
