Once you or your employer contributes funds to a health savings account, those funds are yours to keep and use on qualified health care expenses. If you decide to enroll in a medical flexible spending account the following year, you may not enroll in the Consumer-driven Health Plan option that same year. The HSA that you had previously will remain open, and your funds will remain available for your use; however, you will be responsible for the monthly retail fee that the state has been paying while you were an active HSA account holder. The HSA administrator will deduct these administrative fees from your HSA funds each month. You may also choose to transfer your HSA balance to another entity to serve as custodian of the account.
