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 WHOOP 4.0 Wearable Health & Activity Tracker with my HSA or FSA?

Yes. This product qualifies as a medical expense — pay with your HSA or FSA card and you're done.

Do I need a doctor's note or LMN to buy the WHOOP 4.0 Wearable Health & Activity Tracker?

No — this product qualifies as a medical expense on its own. Pay with your HSA or FSA card; no letter required.

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).
