Everything you need to know about Questions to Ask Before Choosing a TMS Clinic — how it works, what it costs, and how to find a provider who actually knows what they're doing.
The TMS Patient Buyer's Guide
Everything to know before your first consult — questions to ask, what to expect, and how to compare providers.
Most people book the first TMS clinic that takes their insurance. That’s a reasonable instinct, but it can also be the difference between a strong response and a so-so course. The clinic you pick controls the device, the protocol, the targeting method, who delivers the sessions, and what happens if the first round doesn’t work — and those choices matter a lot.
Here’s the question list to bring to your consultation. Most can be answered in 30 seconds. If a clinic dodges any of these, that’s a signal in itself.
On the Device and Technology
1. What device do you use? Several manufacturers have FDA-cleared TMS devices for depression in the U.S., including Neuronetics (NeuroStar), BrainsWay, MagVenture, and Magstim. They have different coil designs, different protocols, and slightly different evidence bases. There’s no single “best” — but the answer should come quickly and confidently.
2. Do you offer theta-burst (iTBS) protocols, standard 10 Hz rTMS, or both? iTBS is faster (3-9 minutes) and was shown to be non-inferior to standard 10 Hz rTMS for depression in a large trial in The Lancet (2018). If a clinic only offers one, ask why and whether the other might fit your situation better.
3. Do you offer deep TMS (dTMS) for OCD? BrainsWay’s Deep TMS system (2018) and MagVenture’s system (2020) have FDA clearance for OCD. If you’re being treated for OCD, ask which device the clinic uses and whether it is cleared for that indication; otherwise the protocol would be off-label.
4. How do you target the treatment area — 5-cm rule, F3 method, or neuronavigation? Neuronavigation (using your own MRI to pinpoint the exact spot) is being studied as a way to improve outcomes, though the evidence is still developing and it’s not universal. The 5-cm rule and the F3/EEG method are both reasonable; what you don’t want is a vague answer.
On the Protocol and Course
5. How many sessions in a standard course, and how often per week? Standard depression: 30-36 sessions, 5 days a week. iTBS: similar count, faster sessions. Anything wildly different deserves an explanation.
6. What’s the first session like — and how long does it take? The first session includes motor threshold mapping and is typically 60-90 minutes. Subsequent sessions are 20-37 minutes (or 3-9 for iTBS). If they say “30 minutes from day one,” they may be skipping the threshold mapping — not a great sign.
7. How often do you re-measure motor threshold during the course? Practices vary. Ask how the clinic decides when to remap and adjust the dose.
8. Do you offer accelerated TMS (multiple sessions per day) or SAINT-style protocols? Stanford’s SAINT/SNT protocol compresses treatment into 5 days with 10 sessions per day and has reported promising results in small trials. The SAINT Neuromodulation System was FDA-cleared in 2022. Not every clinic offers it — but if your timeline is tight, it’s worth asking.
On Who Actually Delivers the Treatment
9. Who’ll be in the room with me during each session — a psychiatrist, a tech, or no one? Most clinics have a trained TMS technician operating the device, with a physician supervising. Some insurers, such as Aetna, require a psychiatrist (or psychiatric nurse practitioner) to be immediately available during sessions. Ask how supervision works at the clinic.
10. Who is the supervising psychiatrist, and how often will I see them? Expect to see them at intake, mid-course (week 2-3), and end-of-course at minimum. If the supervising MD is “off-site” and you only meet on day one, the quality of the rest of your care depends on the technicians.
11. What’s the technician’s TMS-specific training? Look for clinics where techs have completed device-specific training from the manufacturer and have meaningful experience.
On Outcomes and Tracking
12. How do you measure my response — PHQ-9, MADRS, clinical interview? Good clinics use a validated scale at intake, mid-course, and end-of-course. PHQ-9 is the most common. If they don’t formally track, you can’t know whether you’re responding.
13. What’s your published or internal response rate? Real clinics know this number. Published real-world studies have reported roughly 50-60% response and about a third or more remission for depression (for example, Carpenter et al., 2012). Be skeptical of clinics quoting 80%+ — that’s either cherry-picked or marketing.
14. What happens if I don’t respond to the first course? Standard options: change the protocol (e.g., switch from 10 Hz to iTBS or to deep TMS), change the target (try the right side or use neuronavigation), extend the course, or refer to ECT/Spravato/ketamine. A clinic with no plan B is a clinic that hasn’t seen many non-responders.
On Insurance and Cost
15. Do you handle prior authorization for me? Good clinics do prior auth in-house. If they push prior auth back to you, expect delays.
16. What’s my expected out-of-pocket cost — including deductible, copays, and any fees? Get a written estimate. Costs range widely: from a few hundred dollars with good insurance to well over ten thousand dollars for a full self-pay course.
17. Do you offer payment plans or sliding-scale fees if insurance denies? Many clinics will work with you. If they don’t, ask whether they have referral relationships with research clinics offering subsidized treatment.
On Long-Term Planning
18. What’s your maintenance and re-treatment policy? A substantial minority of responders lose benefit within a year and may need maintenance sessions or a re-treatment course. Ask: How do you decide when maintenance is needed? Is re-treatment covered by insurance for prior responders? How do you handle relapse?
Bonus Soft-Signal Questions
These don’t have right answers but tell you a lot about the clinic culture:
- “Can I tour the treatment room before I commit?” Any reputable clinic will say yes immediately.
- “What’s your policy if I’m 5 minutes late?” A reasonable clinic builds buffer in. A clinic that strictly enforces is one that will be inflexible elsewhere too.
- “Will I have the same technician each day?” Continuity matters — you build rapport and they notice subtle changes in how you’re doing.
- “What’s your emergency protocol if I have a worsening of suicidal thoughts during treatment?” They should have a clear answer involving the supervising psychiatrist and a crisis pathway.
Red Flags to Walk Away From
- No supervising psychiatrist or one you’ll never meet.
- Pressure to pre-pay the entire course before insurance auth.
- No standardized outcome measures. “We can just tell when you’re doing better” is not an acceptable answer.
- No clear plan B if you don’t respond to the first course.
- Marketing that promises specific outcomes (“We have an 85% response rate”). Real medicine doesn’t promise.
- Pushing add-on treatments (“you’ll need our $500 brain training program too”) that aren’t part of standard TMS care.
How to Use This List
You don’t need to ask all 18 questions. Pick the 6-8 that matter most for your situation:
- If you’re being treated for OCD: focus on questions 3, 4, 9 (deep TMS device, targeting, supervising MD).
- If insurance is tight: focus on 15, 16, 17 (prior auth, costs, payment options).
- If you’ve failed prior TMS: focus on 4, 8, 14 (advanced targeting, accelerated protocols, plan B).
- If you want maximum confidence in the clinic: ask 1, 2, 9, 12, 13 (device, protocols, staffing, outcome tracking).
The right clinic answers these in plain language without dodging. The wrong clinic gets defensive or vague. You’ll be in their chair five days a week for over a month — pick well.
