Checking coverage
Can a health account pay for it?
HSA stands for health savings account. FSA stands for flexible spending arrangement. These accounts set aside money with tax benefits for eligible medical costs.
To begin
The purpose of the expense matters
IRS guidance, as of September 2026, allows medical spending for weight loss to treat a disease, such as obesity, that a physician has specifically diagnosed.
Under that rule, spending solely for better general health does not qualify, as of September 2026.
The IRS is the federal tax agency. Ask the person running your account whether it can pay this expense and what proof it needs.
Look a little closer
Ask what paperwork the account needs
A note that explains why a diagnosed disease requires your care is called a letter of medical necessity. Ask the person running your account who must write it.
As of September 2026, IRS rules do not demand paperwork bearing that title. The person running your account may still ask for the letter as proof of the medical purpose.
Would this exact expense be eligible under my account’s terms?
What record of the diagnosis is needed?
Which receipt and payment details must I keep?
Must my doctor write the letter, or can another licensed person treating me write it?

Check extras on their own
As of September 2026, a watch or health sensor does not qualify merely because it tracks health; its primary use must be diagnosing or treating a specific disease.
Ask about a bundled device separately from the medicine or visit. A broad wellness label does not settle the account’s decision.
Chapter recap
Keep this in mind.
Get the account’s documentation rules before counting on its funds. Keep the care invoice and any supporting records together.
