What documentation do I need in order to submit my eligible expenses for reimbursement?

You need to complete a Medical Reimbursement claim form (signed and dated) for each patient (including any dependent enrolled in an employer or union sponsored group health coverage plan that meets the ACA minimum value standard) along with supporting documentation for each expense such as an itemized bill from the provider and the Explanation of Benefits (EOB) from your insurance carrier.

If you are submitting through the website at www.iatsenbf.org:

  • You do not need to complete a claim form however all of the above will be required and you will also be required to check off a box certifying the following:
    • The submitted expenses have not been previously reimbursed and are not reimbursable under any other health plan coverage
    • The submitted expenses are qualified medical expenses as defined by the Internal Revenue Service under IRS Publication 502 (as described in our MRP Guidebook)
    • The submitted expenses are for a dependent enrolled in an employer or union sponsored group health coverage plan that provides minimum value (effective January 1, 2017)
    • If the reimbursements requested are for health insurance premiums, that those premiums were paid on a post-tax basis (eg. Not through a pre-tax flex spending account or pre-tax deductions made by you or your spouse’s employer through payroll deductions).
    • That all the information you have provided in support of the claim you are submitting is complete, true and correct and all charges for which you are requesting reimbursement were paid by you or your dependent, where applicable.

Please note: You must be enrolled in the Plan C-MRP both when the expense is incurred and when you submit a claim for reimbursement. To be eligible for reimbursement under the Plan C-MRP, your expense must be a qualified post-tax medical coverage premium or appear on the list of qualified unreimbursed medical expenses. Please refer to the Medical Reimbursement Guidebook for Plan C  and Plan R-MRP SPD  for a list of qualified expenses.

If you would like to have your payment directly deposited to your bank account, you must fill out a direct deposit form or go to our website, log into your account and click and the “change direct deposit information” tab to enter your banking information. Note, once an MRP direct deposit form/website request is received, a pre-notification file must be sent to your bank first. Once the pre-notification has been successfully sent and your bank confirms that the banking information submitted is correct, the next reimbursement you receive will be sent via direct deposit. The verification of the account can take up to two weeks and can take longer if the account information is not entered correctly the first time. Please be sure to update your direct deposit information immediately if your banking information changes. Direct deposit information cannot be updated over the phone. Your payment will be directly deposited to your account once the claim has been processed and a separate explanation of benefits will be sent via mail. The explanation of benefits is also viewable online via the website at www.iatsenbf.org.


Before you fill out the direct deposit form, be sure you know your bank’s routing number and your account number. If you have a checking account, this information can be found on the bottom of a check (see image).
