I made a corset and paid for it myself, but I'd like to know about part of the money being refunded.

Your application may be covered by insurance. If you are eligible for insurance after the content review, the medical expenses will be paid at a later date (approximately 3 months after the application), excluding the copayment. However, please note that the payment will not be made if two years have passed since the day following the day on which the medical expenses were paid.
