Does HSA cover weight-loss medication?
Weight-loss medication is HSA-eligible when a physician prescribes it to treat a specific diagnosed disease — such as obesity, hypertension, or heart disease — but not when it's taken for general health or appearance.
What flips the answer
- Covered when
A physician prescribes the medication to treat a specific diagnosed disease such as obesity, hypertension, or heart disease.
- Not covered when
The product is taken for general weight loss or appearance without a diagnosed condition.
- Not covered when
It's an over-the-counter diet supplement bought for general health with no physician recommendation.
The IRS treats weight-loss treatment as medical care only when it's prescribed to treat a specific disease diagnosed by a physician. Under that rule, prescription weight-loss drugs ordered to treat diagnosed obesity or another disease the excess weight is causing are qualified medical expenses you can pay from an HSA or FSA.
By contrast, medications, supplements, or programs taken just to lose weight for general health or to look better are explicitly excluded, even if a doctor generally endorses losing weight. The deciding factor is a documented diagnosis and a treatment purpose, not the drug itself.
Over-the-counter diet pills and supplements are the weakest case: dietary supplements for general health are not eligible, and OTC weight-loss products typically require a physician's recommendation tying them to a diagnosed condition to qualify. Keep a Letter of Medical Necessity to substantiate borderline purchases.
