Traditional HSA/FSA spend
HSA spend methods

Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) let you set aside pre-tax dollars for healthcare costs. However, their applications have traditionally been limited to expenses such as co-pays, deductibles, and basic medical supplies like sunscreen and bandages—leaving many meaningful health investments out of reach.
