The documentation is the same information required for traditional paper claim forms. You must keep copies of all transaction receipts for each card purchase so that these can be provided to the administrator upon request. This includes itemized cash register receipts that list the merchant name, name of the item/product, date and amount (for items such as hearing aid batteries, contact lens solutions or over-the-counter medicines/drugs), insurance plan Explanation of Benefit (EOB) statements, and itemized statements (for vision or other healthcare expenses). (It does not include the credit card receipt.) For prescription drugs purchased at a pharmacy, this would include the pharmacy receipt (or you can request a printout from your pharmacy). Whenever possible, however, you should purchase prescriptions through any available mail-order service as this not only reduces your costs, it can also help reduce or even eliminate the documentation requirements. We recommend you keep all documentation in a separate envelope at home or work for the entire plan year.
