Eligibility & Coverage FAQs

Written by Caeli's benefits team. If we haven't answered your question, the extension's in-app chat is staffed by humans.

Can I buy the NiaCel® 400 with my HSA or FSA?
With a Letter of Medical Necessity, yes. The IRS treats many wellness products as "general wellness" by default; an LMN from a clinician documents the medical purpose and converts the purchase into a qualified medical expense. Caeli automates the LMN flow inline during checkout.
What is a Letter of Medical Necessity (LMN), exactly?
A short note from a licensed clinician naming the product, the medical condition it treats, and the duration of treatment. It's a single page. Caeli's telehealth partners issue one through an intake that runs concurrently with merchant checkout — under 3 minutes from your side.
What if I get audited?
Caeli vaults your LMN, the itemized receipt, and your symptom intake together for the full 7-year IRS audit window. If your HSA administrator or the IRS asks, you forward one folder.
Does my wellness stipend (LSA) cover this?
Maybe — LSA coverage is set by your employer's plan, so it varies by person. Caeli reads your employer's LSA categories and tells you whether you can pay this way — often with no paperwork. If you have both an LSA and an HSA, Caeli steers you to spend the LSA first (it can expire) and protect the HSA (it compounds).
Does Caeli ever see my medical records?
Only the intake answers you choose to share with the telehealth clinician. Caeli itself does not store diagnoses; we store the LMN as the clinician issues it.
