This article covers the most common specific reasons HSA and FSA reimbursement claims are denied, along with what you can do to fix each situation.
Many claim denials come down to documentation that doesn’t meet your administrator’s specific requirements. These are often the most straightforward to resolve.
Some administrators deny LMN-based claims on the grounds that the signature must be handwritten rather than electronic. In most cases, this requirement is not supported by U.S. law.
Under the U.S. Electronic Signatures in Global and National Commerce Act (15 U.S. Code § 7001), a signature, contract, or record cannot be denied legal effect, validity, or enforceability solely because it is in electronic form. An LMN does not fall under any of the narrow exceptions to this rule (such as wills).
What we recommend:
Certain administrators flag claims when the address of the provider who signed the LMN is in a different state than the patient’s address. This doesn’t automatically disqualify your claim, but it can trigger a manual review or outright denial with some plans.
If this is the reason for your denial, contact Truemed. Depending on your administrator’s policy, there may be steps we can take to address this, or we can help you understand what documentation to provide when you appeal.
Some administrators only accept Letters of Medical Necessity signed by a Medical Doctor (MD), and will deny claims backed by an LMN from a Nurse Practitioner (NP) or other licensed provider. If your denial cites the provider’s credentials, reach out to Truemed. We can sometimes accommodate a request for an LMN signed by an MD to meet your administrator’s requirements.
Many states have adopted “full practice authority” allowing Nurse Practitioners (NPs) to sign letters of medical necessity. However, some states like Alabama, Mississippi, South Carolina, and Tennessee often require a physician (MD/DO) to sign your LMN. This is already considered within your Truemed flow and those states will always include an MD signature.
These denials relate to the product or service itself, either how it was categorized or how the medical necessity was documented.
HSA and FSA reimbursement requires that a product be used for the treatment or management of a diagnosed medical condition, not purely for prevention or general wellness. If your administrator determined that the product on your claim is preventive in nature, the claim may be denied even if you have an LMN.
To address this, the LMN needs to clearly connect the product to the treatment of a specific diagnosed condition. If you believe your situation meets this standard, contact Truemed to discuss whether your LMN can be updated to more clearly reflect the medical necessity.
This denial means the diagnosis listed on your LMN doesn’t clearly connect to the product you purchased. For example, a diagnosis focused on one health area may not be sufficient justification for a product in a different category.
In some cases, taking the Truemed qualification survey again can result in a more appropriate diagnosis being linked to your purchase. Contact Truemed to discuss whether a survey retake or an updated LMN would address this denial.
If you purchased multiple items in a single transaction but only some of them appear on your claim, or if certain products were left off, you may be able to add them.
How this happens: When a cart contains a mix of eligible and ineligible items, the claim submitted to your administrator may only reflect the items Truemed identified as eligible at the time of your qualification. If you believe an eligible product was left off, contact Truemed with your original order details.
What documentation is needed per product: Each item added to a claim needs to be supported by:
How to proceed: Email support@truemed.com with your order confirmation, the items you believe should be included, and any denial notice you received. Truemed will review whether the missing products can be added to your documentation and guide you on next steps with your administrator.
