Do I need a doctor's note or LMN to buy the Mobilizer Knee?

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).

The smart play

Multi-wallet

Spend FSA first. Put the rest on credit and shoebox it for deferred HSA reimbursement.

Spend your FSA first — it resets yearly. Cover the rest on credit and shoebox it for deferred reimbursement years later from your (still-compounding) HSA.

The magic, behind the scenes

Instant telehealth, in-checkout

If a product ever needs clinical documentation, Caeli handles the intake inline — under 3 minutes, no extra tab.

Credit-card → shoebox → HSA later

Pay with a credit card to stack points. Caeli auto-vaults the receipt and signed LMN so you can reimburse from your HSA decades from now — keeping the principal compounding tax-free the whole time.

Direct-from-merchant routing

Every order ships straight from the original retailer. Caeli never marks up the product — same price you'd pay without us.
