Flexible Spending Accounts (FSAs) and Health Savings Accounts (HSAs) reimburse you for eligible medical expenses — but only if you can produce an itemized receipt. Here's what your receipt needs to include, which items qualify, what to do when the original receipt is lost, and how to avoid the most common reimbursement-denied mistakes.
The short version
An FSA/HSA reimbursement receipt needs five pieces of information:
- Date of purchase
- Merchant name (pharmacy, store, clinic)
- Itemized description of each product or service
- Amount paid for each item
- Total amount paid
Credit card statements don't qualify. They show that something was bought at CVS for $42.18, but not that the $42.18 was for FSA-eligible items. That's why you need the itemized receipt.
What counts as an FSA/HSA-eligible expense?
The IRS publishes a list of qualified medical expenses in Publication 502. The major categories:
- Prescription medications — anything requiring a doctor's prescription
- OTC medications — pain relievers, allergy medication, cold and flu remedies, etc. (no prescription needed since 2020 thanks to the CARES Act)
- Medical devices — thermometers, blood pressure monitors, glucose meters, CPAP supplies, contact lens solution, etc.
- First aid supplies — bandages, antiseptics, hot/cold packs
- Menstrual care products — pads, tampons, cups (added to eligibility in 2020)
- Vision care — prescription eyewear, contact lenses, eye exams, LASIK
- Dental care — fillings, crowns, cleanings, orthodontia
- Medical co-pays and deductibles — at the doctor's office, urgent care, hospital
- Mental health services — therapy, psychiatry co-pays
Items that aren't eligible (but commonly assumed to be): vitamins and supplements (unless prescribed), gym memberships (unless prescribed for a medical condition), cosmetic procedures, toiletries, food (even "medical food" unless specifically prescribed).
Receipts that work for FSA/HSA
CVS receipts
CVS receipts mark eligible items with codes next to the price (often "F" for FSA-eligible). The receipt also shows the prescription details separately when applicable. CVS receipts are the gold standard for FSA/HSA reimbursement because the eligibility codes are pre-applied.
If you lost your CVS receipt, you can check your ExtraCare account history online, the CVS app, or generate a replacement CVS receipt that matches your card statement.
Walgreens receipts
Walgreens receipts identify FSA-eligible items with similar codes. MyWalgreens members have purchase history available online and in the app. Same general workflow as CVS.
Pharmacy receipts (chain or independent)
Any pharmacy receipt with itemized line items and dates works. Insurance EOBs (Explanation of Benefits) also qualify for prescription co-pays — you don't always need the pharmacy receipt if you have the EOB.
Big-box stores (Walmart, Target, Costco)
Walmart, Target, and Costco receipts work for OTC items if they include itemized lines showing what you bought. The receipt doesn't need to have FSA-eligibility codes pre-applied — you can identify the eligible items yourself when submitting.
Doctor's office and clinic receipts
Co-pay receipts from medical providers, urgent care, hospitals, and specialists all qualify. They typically show the date of service, patient name, services rendered, and amount paid.
What doesn't work
- Credit card statements alone — show the transaction but not what was purchased
- Order confirmations without itemized detail — "Amazon order #12345 — $89.34" isn't enough; you need the items list
- Photos of receipts that are illegible — administrators reject smudged or partially visible receipts
- Handwritten receipts without a merchant name — must be from a recognised provider
- Receipts older than the plan year + grace period — most FSAs only cover the current plan year plus a short grace period
What to do when you lose an FSA receipt
If your original is gone, you have a few options ranked by what your administrator will accept:
- Check the merchant's loyalty account or app. CVS ExtraCare, MyWalgreens, Target Circle, and the Costco app all preserve purchase history with FSA codes intact.
- Contact the merchant for a reprint. Pharmacies in particular can reprint at the counter if you have your card or member ID. Allow time for this — it's not always immediate.
- Request an EOB from your insurer. For prescription co-pays, the EOB serves the same purpose as the pharmacy receipt.
- Generate a replacement receipt. If the above options don't work and you have the date, items, and amount from your card statement, generate a CVS receipt matching the actual transaction. Note: the items must match what you actually bought — your administrator can request additional verification.
Common reasons administrators reject claims
- Receipt doesn't show date. Pretty common with poorly preserved paper receipts.
- Receipt total doesn't match claim amount. Even a $1 mismatch triggers rejection.
- Items aren't FSA-eligible. The most common rejection. People confidently submit vitamins, supplements, and general toiletries that don't qualify.
- Receipt is for an expense outside the plan year. Claim was submitted late or for a pre-plan-year purchase.
- Receipt is for someone else. FSA expenses must be for the participant, their spouse, or qualifying dependents.
FSA "use it or lose it"
FSA funds typically don't roll over — unused balance expires at year end (some plans offer a $640 carryover or a 2.5-month grace period). If you're approaching the deadline with funds remaining, the FSA Store and Amazon's FSA section list eligible items you can buy quickly. After purchase, submit your receipts before the administrator's filing deadline (often March 31 of the following year).
HSAs are different — funds roll over indefinitely, and there's no deadline pressure. But you still need itemized receipts to substantiate withdrawals at tax time.
Bottom line
FSA and HSA reimbursement requires itemized receipts with date, merchant, items, and amounts. CVS and Walgreens pre-apply eligibility codes, making them the easiest receipts to submit. If your original is lost, check the store loyalty account first, contact the merchant second, and generate a replacement matching your actual transaction as a last resort.
