Eligibility Guide

What's FSA Eligible? The Complete Guide

Short answer: an expense is FSA eligible when it's for the diagnosis, treatment, or prevention of a medical condition — the IRS "qualified medical expense" test. Everyday health products usually qualify; general-wellness and cosmetic items usually don't, unless a provider documents medical necessity.

How FSA eligibility actually works

Every eligibility question traces back to one definition: IRS Publication 502 and Section 213(d), which cover expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease. Products that treat or monitor a medical condition qualify. Products that promote general health — however genuinely healthy — usually don't.

Over-the-counter medicines and menstrual products no longer require a prescription to qualify. For borderline items — where a product could be either medical or general-purpose — a Letter of Medical Necessity from your provider can move it into eligible territory. And your plan administrator has the final say on any individual claim, so plan documents always trump a general rule.

The guides below go item by item: the verdict, the IRS reasoning, the edge cases, and what to do when a claim gets rejected.
