Typically, functional lab tests are considered alternative medicine and aren't covered by insurance. As a holistic practitioner, I don't offer insurance billing services, but you can request statements or use receipts for potential reimbursement from your insurance carrier. You can pay for lab fees upfront using an HSA, and I recommend keeping receipts for your records.
While out-of-pocket expenses may seem challenging, investing in functional lab testing has personally saved me time, money, and frustration on my health journey. Your health is valuable, and the cost of functional care is an investment in your well-being.
