Yes, in many cases you can use a Health Savings Account (HSA) or Flexible Spending Account (FSA) to pay for a WHILL device. Since WHILL Models are FDA-cleared Class II medical devices, they generally qualify as eligible medical expenses under IRS guidelines.
To ensure coverage, check with your HSA/FSA administrator, as they may require a Letter of Medical Necessity from your healthcare provider. Always confirm with your plan provider before purchase to avoid unexpected denials.
