View full detailsCommon HSA/FSA Questions
Short, plain-English answers your shoppers need—organized by what they’re most likely to ask first.
How does using HSA/FSA save me money?
HSA/FSA funds are pre-tax. Paying with these accounts (or reimbursing after purchase) uses dollars that aren’t subject to income tax—often resulting in up to 40% savings depending on your tax situation. Always check your plan rules.
Which products are eligible?
Eligibility is determined for each shopper via a quick online assessment, and a Letter of Medical Necessity (LMN) is part of the process to qualify for payment or reimbursement with pre-tax HSA/FSA dollars. Products that commonly qualify are labeled to help you find them faster.
What is a Letter of Medical Necessity (LMN)?
An LMN is a provider’s letter stating a product is medically necessary for your condition. Complete our brief assessment; if approved, your LMN is issued digitally and typically valid for 12 months. You’ll receive it by email and can access it anytime in the Medpaid patient portal.
How do I get a copy of my Letter of Medical Necessity (LMN)?
Log in to the Medpaid patient portal. Your username is the email you used at checkout. If you haven’t set up your account yet—or need to reset—select “Forgot password” to create or reset your password. Once signed in, you can download your LMN anytime.
Pay with HSA/FSA vs. Reimbursement—what’s the difference?
Pay with HSA/FSA: Complete the quick assessment to obtain an LMN and, once qualified, pay at checkout with your HSA/FSA card.
Reimbursement: Pay with any card, complete the assessment to obtain an LMN, then submit your receipt and LMN to your HSA/FSA administrator for repayment. Step-by-step help: How to pay with HSA/FSA.
How fast is the approval process?
The assessment takes less than 1 minute, and determinations are typically made in seconds. Approved LMNs are emailed immediately.
What information do I need for the assessment?
Basic contact info, a short description of your symptoms or goals, and (optionally) relevant history. No lengthy medical records are required for most shoppers.
Can I use a regular credit card and get reimbursed later?
Yes. Keep your receipt and LMN. Submit both to your HSA/FSA provider for reimbursement according to your plan’s rules and timelines.
Are there any fees or extra costs?
The LMN is complimentary when taken with an associated purchase. If you prefer an individual LMN without a product purchase, a marginal fee may apply.
How long does my LMN last?
LMNs are typically valid for 12 months from the date of approval unless your plan specifies otherwise.
I don’t have an HSA or FSA. Can I still purchase?
Absolutely. You can purchase with any card. If you later open an HSA/FSA and your item qualifies with an LMN, reimbursement may be possible per plan rules.
HSA and FSA accounts are U.S. benefit types; availability may differ outside the U.S.
