August 19, 2025 | 5-minute read

We make it easy to submit FSA claims and stay informed

Whether you're new to a flexible spending account (FSA) or a longtime account holder, filing a claim doesn’t have to be complicated. We give you clear information about the steps involved, helping you avoid delays in getting reimbursed. 

Choose the filing option that’s best for you

There are several ways to file a flexible spending account claim:

  • Online through optumbank.com or the Optum Bank mobile app
  • By mail 

All options start by signing in to your online account. From there, navigate to the claims section. To file by mail, find and download the claims form you need, fill it out and mail it to us. To file online, follow the prompts.

What to include for faster FSA claim reimbursement

Providing the right information is critical to getting your FSA claim approved, so make sure you include the following:

  1. Name of provider
  2. Name of patient (who received the item/service)
  3. Description of service
  4. Date of service (not the date payment was made)
  5. Amount charged (not the amount paid as this could differ from amount charged for eligible service/item)

Once you’ve entered all requested information and provided all required documentation, carefully review your claim, then submit it. 

Track the status of your flexible spending account claim online

After submitting your FSA claim, you can track its status by signing in to your account. You’ll also be able to:

  • View your FSA account balance.
  • Set up alerts and reminders for your FSA.
  • Find other account information and tools.

Use your payment card and skip the claims process

When you use your Optum payment card to pay for FSA-eligible expenses, many purchases are automatically approved. This helps reduce paperwork and speed up processing. See your plan details for specific information. 

Support for every type of FSA expense

Whether you have a health care, dependent care or limited purpose FSA, we’re here to help you use your flexible spending account benefits with confidence. For more information, visit our flexible spending account page.

Find answers to common questions about FSA claims

Filing and submitting claims

Typically you need an itemized receipt that includes the provider’s name, patient’s name, date(s) of service, description of the service or item and the total amount charged. This information is often found on an itemized receipt or an explanation of benefits (EOB).

It depends. See your plan’s details for guidelines on eligible health care, dental and vision expenses that can be reimbursed. 

Use our expense eligibility tool or the expense checker on our mobile app. 

Yes, just make sure that each expense is clearly documented.

Documentation and receipts

You need an itemized receipt showing the name of the provider and the person who received the service, the date and description of the service and the amount charged.

It depends. Sometimes an EOB is required, especially for insurance-related expenses.

If you lose a receipt, try one of the following:

  • See if you can get a copy of the receipt from the store or provider. 
  • Request an EOB from your insurance carrier if the expense went through insurance.  
  • Contact your FSA administrator for guidance.

Timing and processing

Most FSA claim reimbursements are processed within a few business days.

For information, check your plan details.

Yes, but only if the expenses were incurred while you were covered and within the deadlines for the plan year.

Claim denials and fixes

Denials are often the result of missing or incorrect documentation. If your claim is denied, you’ll get instructions on how to correct and resubmit your claim.

Your FSA claim may be closed, so it’s important to respond promptly.

Yes, simply follow the appeal instructions provided in your denial notice.
