coordination of benefits should be submitted before you claim amounts under your HSA. This will allow you to make the most of your insurance benefits.
Depending on the type of expenses incurred, there are several ways you can submit your claim:
Transactions carried out using a payment card or through a healthcare professional aren't automatically submitted for reimbursement under an HSA. In both cases, if the expenses incurred aren't fully reimbursed, you'll have to pay your healthcare professional the difference, and then submit a claim for that amount.
Whether you're submitting a claim online or by mail, you must let us know which amounts you want to apply to your HSA. Outstanding amounts aren't automatically submitted to your HSA for reimbursement.
