Common questions about Momentous
Are Momentous products HSA or FSA eligible?
All 77 Momentous products Caeli lists qualify for HSA or FSA, 7 outright and 70 with a letter of medical necessity.
Do you need a letter of medical necessity for Momentous?
70 of the Momentous products Caeli lists need one. These are dual-purpose items, which become eligible when a clinician ties them to a documented condition. Caeli can arrange the letter as part of checkout.
How does Caeli handle the letter of medical necessity for Momentous products?
At checkout, Caeli runs a short telehealth intake for the Momentous product in your cart. A clinician reviews it and, where the product fits a documented condition, issues the letter, which Caeli files with your receipt. No doctor's visit, and the purchase goes through as an HSA or FSA expense.
What is a letter of medical necessity, and how do I get one for Momentous?
A note from a licensed clinician saying an item treats or manages a specific condition — which is what makes a dual-purpose Momentous product HSA or FSA eligible. Caeli gets you one in about three minutes: a licensed provider reviews a few questions and signs it, and it stays valid for 12 months, for that product and similar ones.
What qualifies for a letter of medical necessity on Momentous products?
A documented condition the Momentous product helps treat or manage — the clinician decides, against what you describe in the intake. For what Caeli lists here that is usually metabolic & nutritional support. You do not need a diagnosis in hand to start; the questions are the diagnosis step.
Can I split a Momentous purchase between my HSA or FSA card and a credit card?
Yes. At checkout Caeli charges the eligible amount to your benefit card and puts the rest on a regular credit card, in one order, and you can combine funds from more than one benefit account the same way. The receipt is stored in your Caeli account for reimbursement or an audit.
