Is weight-loss programs FSA eligible?
Sometimes — weight-loss programs are FSA eligible only when treating a diagnosed condition, with a letter of medical necessity.
A program to treat diagnosed obesity, hypertension, or heart disease can qualify with a doctor's letter. General fitness or appearance-driven dieting doesn't — and food itself (meal-plan deliveries) almost never qualifies even with a letter.
Before you buy: get the letter first
- Ask your doctor for a letter of medical necessity that names the condition and why this is treatment, and keep it on file.
- Then pay with your FSA/HSA card or file a claim with the letter attached. Buying before you have the letter risks a denied claim.
Does the same answer apply to an HSA?
Yes. FSAs and HSAs share the same qualified-medical-expense rules (IRS Publication 502), so eligibility is identical. The difference is the deadline: FSA money is forfeited at the end of the plan year, while HSA money never expires.
