About The Functional Medicine MD
What is The Functional Medicine MD?
The Functional Medicine MD is a functional medicine and IV hydration clinic at 3020 Tazewell Pike in Knoxville, Tennessee. Dr. Lela Iduna founded it in 2018 and is its prescriber. She completed internal medicine training at Yale New Haven Hospital, is also certified in emergency medicine, and became certified by the Institute of Functional Medicine in 2015. The clinic serves Knox, Anderson and Blount counties.
Its main work is functional medicine and IV therapy. Services include IV hydration, IV vitamin therapy, chelation, stem cell injections, ozone therapy, laser pain therapy, Lyme disease services, microneedling, and functional testing such as ANS and nitric oxide testing. Its one anti-aging offer is an IV built on NAD, the only medication it names. It does not list weight loss, hormone or peptide treatment. Its Google rating is 4.4 from 53 reviews.
What does it cost?
It publishes most of its prices. The initial functional medicine appointment is $450 for a 60-minute visit, and a personalized follow-up is also $450. Further follow-ups run $225 to $338, spaced 6 to 12 weeks apart. A free 15-minute phone consultation comes first. IV therapy runs $99 to $350, and most IVs are $250. The anti-aging IV has no separate price, and Dr. Lela recommends monthly anti-aging IV treatments. Microneedling is $300, microneedling with PRP is $900, and laser pain therapy is $500 for 6 sessions. Stem cell injections and hyperbaric therapy are prices on request. The blood panel is $598 without insurance, against a typical price of $6,000. Medicare and Medicaid patients pay nothing for it, and other insurance carries a maximum out-of-pocket cost of $350.
In its own words: "We have not yet been accepted into an insurance network, so we can't bill your insurance." It offers a superbill you can submit to your insurer for out-of-network reimbursement. It accepts credit cards and health savings or flex spending cards.
What should you ask before you book?
Ask what the anti-aging IV costs per visit and whether a monthly plan changes the price. Ask whether the NAD IV is part of a medical program with physician review or a single infusion, since it does not say which. Ask whether the NAD is brand-name or compounded. Ask what testing at the first visit costs on top of the $450, because labs are priced separately. Ask whether the buy one, get one free anti-aging special is still running. Ask how a telemedicine "virtual visit" is priced, and how cancellations and rescheduling work, since it does not publish those terms.
Who is it a good fit for?
This is a good fit if you want functional medicine or IV therapy in Knoxville and are prepared to pay cash, since it is not in any insurance network. It is a weaker match if you want weight loss, hormone or peptide care, which it does not list.
