Citi Benefits Handbook
At any time, up until June 30 of the following plan year, you may be reimbursed for eligible expenses up to the total amount you elected to contribute for the plan year. In order for a claim to be deemed an eligible expense to be reimbursed, you must provide any pertinent documentation to establish that a claim is eligible for reimbursement, which may include documentation that a service provided in connection with a claim was medically necessary. Note: If your 2019 claims deadline falls within the National Emergency, your deadline will be recalculated to allow an additional four months to submit claims for reimbursement from the end of the National Emergency.
Regardless of whether a claim is paid or reimbursed, if you increase your contributions during the plan year because of a qualified change in status, you may pay for claims or be reimbursed for claims from the increased amount only for expenses incurred after the date of the qualified change in status.
