Common Questions

Are Flex Health and Sika Health both HSA-eligible?
Both support HSA/FSA and LMN evaluation flows for participating merchants. The underlying purchase still must satisfy the medical-care rules, and the account administrator makes the final decision.
Which has more brand partners?
Merchant directories and integrations change. Check whether your specific merchant currently offers Flex or Sika rather than relying on a fixed network-size claim.
Do I pay extra to use either?
Pricing depends on the platform product and merchant flow. Flex's current gym/studio reimbursement product lists a $15 customer LMN fee. Confirm both platforms' current terms at checkout.
Will my HSA card work at checkout?
It depends on the merchant integration. Some flows support direct HSA/FSA card checkout; others require payment with a normal card followed by reimbursement.
How do I track these purchases for my HSA?
Save the receipt and the LMN PDF from your Flex or Sika account. Upload both to HSA Trackr to keep a complete record.
