Tap into a $147B+ HSA/FSA market that’s still underused

- Perfect for high-intent wellness ecommerce. Supplements, wearables, recovery tools, and more can be eligible when used to treat specific conditions.
- Medpaid connects the dots. Eligibility rules, LMNs, telemedicine, and HSA/FSA payments sit in one platform built for ecommerce.

Compliance center: HSA/FSA, telemedicine, and LMNs for ecommerce
Give your legal, compliance, and payments teams confidence that HSA/FSA payments are being handled correctly—with telemedicine workflows, Letters of Medical Necessity (LMNs), and audit-ready documentation built into Medpaid.
Informational only. Not legal, tax, or medical advice. Merchants should consult their own counsel and plan administrators when making compliance decisions.
How does Medpaid use telemedicine and LMNs for HSA/FSA eligibility? ▾
For products that may be eligible when medically necessary, Medpaid offers a structured health assessment that collects product-specific, clinically relevant information. Licensed providers review each assessment and can issue a Letter of Medical Necessity (LMN) when appropriate. This documentation supports plan substantiation that the expense is primarily for medical care rather than general wellness.
What can merchants safely say on product pages about HSA/FSA eligibility? ▾
Best practice is language such as “May be eligible with HSA/FSA when medically necessary; LMN may be required.” Avoid “guaranteed eligible”, “IRS-approved”, or explicit disease-treatment claims unless you have the regulatory posture and substantiation to back those claims.
How does Medpaid keep checkout compliant with mixed carts? ▾
Medpaid supports a cart-routing pattern where only eligible items flow through the HSA/FSA pathway. Real-time SKU validation and split-tender logic help ensure non-eligible items stay on standard payment methods. Eligibility checks and routing events can be logged for audit support.
How is customer privacy handled for assessments and LMNs? ▾
Telehealth interactions use secure communication methods, with controlled access to LMNs and assessment data. Medpaid collects the minimum necessary information to support clinical review and eligibility documentation, keeping clinical details within Medpaid systems and out of your storefront analytics tools.
Who is responsible if customers misrepresent information in a health assessment? ▾
Customers must attest that their information is accurate and complete. Providers make clinical decisions based on that information, and reimbursement outcomes are ultimately decided by plan administrators or custodians. Merchants should avoid tax advice and direct customers to their HSA/FSA administrator for questions about reimbursement.
