HomeWelcome Participant

Welcome to Ameriflex

We're excited to be your partner in health savings. Tax-advantaged spending accounts allow you to set aside pre-tax dollars from your paycheck to reimburse yourself for a wide range of eligible medical expenses. With Ameriflex, you'll receive an Ameriflex Debit Mastercard® directly connected to your accounts, and access to an online participant portal that allows you to view transactions and account activity, review and update account information, file claims for reimbursement, and much more.

Your Ameriflex Debit Mastercard ®

You’ll receive your Ameriflex Debit Mastercard® linked to your Ameriflex account, which you can use to pay for eligible medical care and expenses. If you have multiple accounts, such as a flexible spending account and dependent care account, your card links to both accounts and knows which funds to pull from when you make a purchase.

New cards arrive in white unmarked envelopes for security purposes and typically arrive in 7-10 business days. Cards are automatically issued when you are enrolled in an account and are good for three years. The month of expiration, a new card will automatically be issued and mailed to the address on file. New cards do not need to be activated and are ready to use as soon as they arrive. If you lose your card, you can always request a complimentary replacement by logging into your Ameriflex account or the Ameriflex mobile app.

Want to pay for your medical expenses with even more ease? Add your Ameriflex Debit Mastercard® to your mobile device’s digital wallet for more seamless transactions.

Card Lost or Stolen?

If your Ameriflex Debit Mastercard® has been lost or stolen, you can order a replacement with just a few clicks in the participant portal. Log in to the portal, select the More tab at the top of the home page, then choose Debit Cards from the dropdown menu. Select the family member whose card is being replaced, then click the Report Card as Lost or Stolen and Issue a Replacement button to have a replacement sent to you.

Important: Once you request a replacement card, the old card is automatically deactivated and cannot be reactivated. Be sure the existing card cannot be found before requesting a replacement.

Download the Mobile App

If you have an Apple or Android device, be sure to download the Ameriflex mobile app. This is the quickest and easiest way to access your account on the go. The mobile app offers the same functionality as your online account in the participant portal.

When & Where to Use Your Card ®

Before you make a purchase, verifying that the expense is eligible under your plan’s rules is important. Flexible spending accounts (FSA) and health savings accounts (HSA) reimburse various expenses such as copays, dental and vision, prescriptions, etc. Health reimbursement arrangements (HRA) and dependent care accounts (DCA) reimburse specific expenses unique to those accounts. A Commuter Reimbursement Account (CRA) comes in two different options: a parking account and a parking account.

Most healthcare-eligible items must be considered “medically necessary” and treat a specific condition. Under recent legislation, some over-the-counter items, such as bandages, sunscreen, and first-aid supplies, have been approved. Verifying that items are eligible before making a purchase is crucial.

Eligibility Lists

Note: For Health Reimbursement Arrangements (HRAs), contact your employer for a complete list of eligible items, as each HRA account will cover different items.

Letters of Medical Necessity

The IRS requires third parties, such as Ameriflex, to verify the eligibility of the service or product. Items and services used to maintain or prevent a medical illness or injury are not eligible expenses. However, the same items and services can be considered eligible if used to treat or cure a medical illness or injury and is accompanied with a letter of medical necessity (LMN) from your primary care physician.

Your medical provider would need to complete a letter of medical necessity, which you would only need to submit once per plan year for a specific treatment. With this letter on file, Ameriflex can more easily process manual claims with your itemized receipt or help clear a substantiation request for a debit card transaction.

If you need to submit a Letter of Medical Necessity, download the Letter of Medical Necessity form, allow your provider to complete and sign it, and submit it directly to the Ameriflex claims team at claims@myameriflex.com. You may also submit the form along with your first claim request.

Accounts Overview

Submitting Claims

Your Ameriflex Debit Mastercard® will be your first line of defense, as a card swipe is technically submitting a claim. However, if you cannot use your card, you must pay the expense out-of-pocket first and then file a claim for reimbursement. You can file a claim to reimburse yourself or your provider via the Ameriflex Participant Portal or Ameriflex Mobile App. Whether submitting a claim to reimburse yourself or your provider, you must choose the account from which you would like the funds pulled and provide either an itemized receipt or an Explanation of Benefits that clearly shows:
  1. Name of the provider
  2. Name of the person who received the service or for whom the item was purchased
  3. The items or services that were rendered
  4. Date(s) of service or purchase
  5. Total patient responsibility or amount charged

Denied Card Transaction?

Understanding common card denials and how to resolve them can ensure smooth transactions and avoid unnecessary frustration when using your Ameriflex debit card. Common Card Denials
  1. Ineligible expense: The item or service is not an eligible expense per the IRS.
  2. Lack of documentation: Some expenses or accounts require itemized receipts or a full explanation of benefits. Confirm what documentation is required for the plan type reimbursement before attempting to use the card again for the expense.
  3. Insufficient funds: The transaction exceeds the existing balance in the account. Account balances can be checked in the participant portal or the Ameriflex App.
  4. Non-eligible merchant: The card is being used at a merchant that is not IIAS-compliant (Inventory Information Approval System) or does not have an eligible MCC (Merchant Category Code).
Here are some general steps to quickly identify the potential reason for a card denial and resolve the issue.
  1. Review your account information: Ensure your account details, including eligibility, balances, and card status, are accurate and up to date.
  2. Check eligible purchases: Always ensure the items and/or services you’re purchasing are covered by your benefits plan.
  3. Wait for system updates: Sometimes, waiting for the resolution may be necessary for technical or system-related issues.
  4. Confirm card information: Transactions may be denied if any information provided was incorrect such as the entered PIN. The active PIN for a card can be confirmed in the Ameriflex Participant Portal.
  5. Contact Ameriflex Participant Services: If you cannot resolve the issue, contact the Participant Services team for further assistance and clarification.

Denied Claim?

It’s frustrating when a claim is denied, but it might be an easy fix. Here are a few reasons why your claim might have been denied:
  • Wrong Document Type: Credit card or bank statements aren’t enough. Additionally, some items require a Letter of Medical Necessity (LMN) from your doctor. To avoid issues, always provide an itemized receipt, an Explanation of Benefits, or a Letter of Medical Necessity (if needed).
  • Missing details on itemized receipt or Explanation of Benefits (EOB): The receipt or EOB you submit must show the patient’s name, the provider’s/store name, the date of service/purchase, the type of service/purchase, and the amount charged.
  • Date of service falls outside of the plan year: The claim submitted has a date of service outside of the active plan year and any applicable run out or grace periods. Check that the claim is being submitted against the correct plan year.
  • Duplicate claim or card transaction: This occurs when the same expense or service is submitted more than once for reimbursement. This can include a previously submitted claim or a card transaction with the same service date and amount.

Following these steps can help resolve a denied claim and prevent future claims from denial:

  1. Read the denial explanation carefully: denial information is provided via email and is also available in the participant portal. For example: missing receipt, expense falls outside of plan year
  2. Gather additional or corrected information: Check your records and gather any missing or corrected documentation. For example, you may need a full explanation of benefits depending on the type of expense. Check that the documents show the required information and contain all pages.
  3. Resubmit the claim: Once everything is in order, resubmit the claim through the participant portal or mobile app. Be sure to include the updated documentation.

Frequently Asked Questions

A: FSA cards rely on how stores process purchases. Even if a store sells mostly FSA-eligible items, your card might not work due to technical issues. While FSAstore.com aims to prevent this by clearly marking eligible items that don’t require a doctor’s note, problems can still occur.   

 

Most retail stores and pharmacies use an IIAS (Inventory Information Approval System). When you use your Ameriflex Debit Mastercard® card to pay for prescriptions, over-the-counter items, or other expenses, the store’s system automatically tells us whether each item is FSA-eligible. The eligibility is based on how the items are coded in the store’s system, which the store itself sets up. Larger retail stores and pharmacies have this system in place, which makes it easier to transmit FSA-approved expenses to Ameriflex. Smaller retail stores, such as local pharmacies and retail chains, may or may not have the IIAS system, which is often dependent on the store.

A: There are a few reasons why a claim might be denied now, even if similar ones were approved in the past:

  • Ameriflex may review claims more carefully to ensure they meet all requirements.
  • Ameriflex may have updated their systems or processes for reviewing documentation, and they may now require stricter adherence to the rules.

A: If you’ve swiped your card and the transaction cannot be auto-verified at the point of purchase, this is usually because the merchant’s (e.g. hospital) payment terminal can’t distinguish if the transaction was for an eligible expense (e.g. surgery) or an ineligible expense (e.g. flowers from the hospital gift store). If Ameriflex cannot auto-verify your expense, you will receive a notification prompting you to log in to your account and provide additional documentation, such as an itemized receipt, Explanation of Benefits (EOB), or a letter of medical necessity. You can upload the documents through your Ameriflex Participant Portal or your Ameriflex Mobile App.

A:  We understand that with a dependent care account (DCA), funds become available as they accrue in your account. To make this process easier, you can set up recurring dependent care claims through your employee account, so you only need to submit a claim once a year. The simplest way to submit a dependent care claim is to fill out the claim form as follows and allow the provider to sign the claim form. In doing so, an itemized receipt is not needed. Once you have completed the form, you can submit the claim through your participant portal or the Ameriflex mobile app.

A: Your receipt or documentation may be missing key info, like:

  • Provider’s name
  • Dates of service (not the date you paid)
  • Description of the care provided
  • The amount charged
  • Future Dates: DCA expenses must be for care that has already happened. Claims for future care won’t be approved.
  • Ineligible Expenses: Only certain types of care qualify, like daycare, after-school care, or summer day camps. Things like tutoring, overnight camps, or school tuition aren’t eligible.
  • Provider Info Missing: The caregiver must provide their name, address, and their Tax ID or Social Security number.
  • Wrong Plan Year: The care must happen within your DCA plan’s dates.

A: Your FSA balance may show $0 at the start of the plan year because your employer hasn’t yet sent your enrollment and contribution details to Ameriflex. Once that information is received and processed, your funds will become available for use. If you don’t see updates after a while, check with your HR department to see the status of your payroll deposits. If you incur expenses before your account is funded, you may still be reimbursed as long as the expense was incurred within the current plan year dates.

A: This can happen because of how payment systems work. When you swipe your Ameriflex Debit Mastercard®, the amount is first authorized (put on hold), but the money isn’t sent to the provider until it’s settled. If something goes wrong during that second step, the provider may see it as denied—even though it looks pending in your account. Your transaction might still be showing as pending due to:

 

  • A technical issue on the provider/merchant side,
  • An incorrect provider/merchant system setup is causing issues with processing FSA payments,
  • A problem with how the expense was coded or processed by the provider/merchant,
  • Or the provider/merchant’s failure to post the transaction after five business days of the date of the original authorization. After five days, the authorization expires, and the previously held funds are returned to the participant’s account balance.

 

Even if you have enough money, the system has to confirm that the purchase meets FSA rules. If anything is off, the transaction might not go through. These processes are generally true across the credit/debit card industry and are not specific to Ameriflex.

A: If you leave your job, you typically lose access to your FSA funds unless you are eligible for and elect COBRA continuation coverage, which allows you to continue contributing to your FSA on an after-tax basis. It’s advisable to use any remaining FSA funds before your employment ends to avoid forfeiture.

A: There is no deadline for reimbursement of qualifying expenses. However, you must have incurred the expense after your account was opened.

A: HSAs can be moved to another employer and are transportable.  The HSA can also stay with Ameriflex under a Personal HSA.

A: Mail to:  Ameriflex HSA, ATTN: Banking Operations, PO BOX 876274, Kansas City, MO 64187-6274. (You should only send forms that require a physical check to be sent with them unless the Trustee/Custodian requires that an HSA Transfer or Rollover Form that is non-check related be submitted to a mailing address.
