The most common thing people say when they first hear about TMS therapy is: “I wonder if I qualify.” It’s the right question — and it has a clearer answer than most people expect. TMS therapy is FDA-cleared for a specific patient population, and the criteria that define that population are well-established, clinically grounded, and directly tied to the evidence base that earned TMS its regulatory approval and insurance coverage (PMC). At WHOA Wellness in Richmond, VA, our consultation process is built around answering this question honestly and specifically for each patient who comes to us.
The Primary Criteria: What FDA Clearance Actually Specifies
TMS therapy is FDA-cleared for adults with major depressive disorder — a condition characterized by persistent low mood, loss of interest in previously meaningful activities, fatigue, cognitive difficulty, sleep and appetite changes, and in some cases thoughts of death or self-harm — who have not achieved satisfactory improvement from prior antidepressant medication (Mayo Clinic; PMC). That “not achieved satisfactory improvement” clause is the clinical core of TMS candidacy, and it deserves some unpacking.
Satisfactory improvement, in clinical terms, means a meaningful reduction in depressive symptoms that allows the patient to function at a level reasonably close to their baseline. Partial improvement — the edge taken off the worst symptoms but persistent struggles with concentration, motivation, energy, or mood — does not constitute satisfactory improvement for TMS candidacy purposes. Nor does improvement that was accompanied by side effects significant enough to require discontinuation. Both scenarios, and more, typically meet the threshold that defines TMS as an appropriate next step.
Most insurance plans require documentation of at least one to two failed antidepressant trials before approving TMS. An adequate trial means the medication was taken at a clinically appropriate dose for a sufficient duration — generally six to eight weeks — without producing adequate relief. If you discontinued a medication early due to intolerable side effects before completing a full trial, that history is relevant and worth discussing during your consultation, as it affects both candidacy determination and insurance documentation.
Who Fits the Profile
The patients who tend to be the clearest candidates for TMS are those with a documented history of major depressive disorder and one or more antidepressant trials that did not produce the relief they needed. That history is common. Research consistently shows that approximately one in three people with major depressive disorder do not achieve adequate relief from first-line antidepressant medications (Mayo Clinic).
Within that group, several presentations make TMS particularly worth pursuing. Patients who have experienced significant medication side effects — weight gain, sexual dysfunction, emotional blunting, cognitive dulling — and want a treatment that does not carry those systemic effects are often strong candidates. Patients who have achieved only partial improvement on antidepressants and are still struggling to function at work, in relationships, or with basic daily tasks may find that TMS addresses what medication left unresolved. Patients with medical conditions that complicate ongoing medication use, or older adults who face particular challenges with medication tolerability, are also within the population TMS was designed to serve.
TMS is also FDA-cleared for adults up to age 86, which matters clinically: older patients have often managed depression for years or decades and face a compounded challenge when antidepressants interact with other medications or produce side effects that are harder to tolerate with age. Our TMS for depression treatment page outlines who typically qualifies in greater detail.
Contraindications: Who Should Not Receive TMS
TMS is not appropriate for everyone, and those contraindications are specific. The primary safety concern involves metal implants in or near the head. Cochlear implants, deep brain stimulators, aneurysm clips or coils, and certain other metallic devices near the skull are contraindications because the magnetic field generated during TMS can interact with them. Standard dental fillings, braces, and joint replacements elsewhere in the body are not contraindications.
A history of seizures or epilepsy is also a contraindication, because TMS can lower the seizure threshold — even though seizures during TMS are extremely rare, occurring in less than 0.01% of sessions overall. Patients with bipolar disorder require careful psychiatric evaluation before TMS is considered, as the treatment protocol may need to be adapted.
During your consultation at WHOA Wellness, we conduct a thorough medical and psychiatric history review specifically to identify any contraindications. This is not a checkbox exercise — it is a careful clinical screening that determines whether TMS is both safe and likely to be beneficial for your specific situation. Results vary by individual, and not every patient who meets the general candidacy criteria will be an ideal fit given their full history.

What Candidacy Looks Like in Practice
The practical question most patients are really asking is: based on what I’ve been through, does TMS make sense for me to explore? The answer usually becomes clear by reviewing three things: your diagnosis, your medication history, and any medical factors that could affect safety.
If you have a confirmed or likely diagnosis of major depressive disorder, have been on at least one antidepressant without achieving the relief you needed, and don’t have metal implants near your head or a seizure history, you are almost certainly worth evaluating further. The formal determination of candidacy happens during your consultation — not before — because it requires a complete review of your history, not just a general checklist applied from a distance.
At WHOA Wellness, we verify your insurance coverage as part of the consultation process. Most major insurance plans — including Aetna, United Healthcare, Cigna, Medicare, Anthem, and many Medicaid plans — cover TMS therapy for patients who meet clinical criteria. Coverage typically requires documentation of prior antidepressant trials, which we help compile and submit during the prior authorization process. There is no obligation to proceed after your consultation, and there is no cost associated with the candidacy evaluation itself.
What Happens After You’re Confirmed as a Candidate
Once candidacy is confirmed and insurance coverage verified, your first TMS session includes a process called motor threshold mapping — a brief, painless calibration procedure in which small, single pulses are delivered while your hand is observed for minor, involuntary movement. This establishes the precise stimulation parameters appropriate for your brain, ensuring that subsequent sessions are personalized to your physiology rather than based on a generic protocol.
From there, your sessions follow a consistent structure: 20 to 40 minutes in a comfortable reclining chair with the Brainsway Deep TMS helmet positioned over your head. You remain fully awake and alert throughout. You can listen to music, read, or simply rest. Most side effects, if any, are mild and resolve within the first week. You can drive yourself home and return to your normal activities immediately after each session.
A full treatment course runs 30 to 36 sessions over six to eight weeks, five days per week. Consistency matters — each session builds on the neuroplastic changes initiated by the ones before it. Most patients begin noticing changes in energy and motivation before emotional symptoms fully lift, typically around weeks three to four, with mood improvements following in weeks four through six. To understand what your first appointment will look like from start to finish, our guide on what to expect at your first TMS consultation walks through every step.
Frequently Asked Questions
Do I need a referral from my psychiatrist or primary care doctor to be evaluated for TMS? No referral is required to schedule a consultation at WHOA Wellness. You can contact us directly, and we will conduct the candidacy evaluation during your appointment. If you are currently working with a psychiatrist or other mental health provider, we encourage coordination — but it is not a prerequisite to getting started.
What if I’m not sure whether my antidepressant trial was long enough to count? Duration and dose both matter in evaluating whether a prior medication trial meets the clinical threshold. If you took a medication for fewer than six weeks, or at a dose below the therapeutic range, it may not satisfy the documentation requirements. This is exactly the kind of history we review during consultation — we can help you assess whether your prior trials qualify and what documentation exists to support them.
Can I be evaluated for TMS if I’ve never been formally diagnosed with major depressive disorder? TMS candidacy requires a confirmed diagnosis of major depressive disorder. If you haven’t received a formal diagnosis but believe your symptoms fit the clinical picture, a consultation at WHOA Wellness includes a review of your symptom history that can inform that determination. We’ll be direct about whether your presentation fits within the scope of what we treat and, if not, how to pursue a formal diagnostic evaluation.
I’ve been on antidepressants for years and they’ve helped somewhat. Does that mean I don’t qualify? Partial improvement that still leaves you struggling significantly is worth discussing. Clinical candidacy is not simply about whether a medication did anything — it’s about whether it produced adequate relief. If you are still experiencing symptoms that meaningfully affect your functioning, quality of life, or sense of wellbeing despite ongoing medication, that history is worth bringing to a consultation.
How soon can I start TMS once candidacy is confirmed? Following candidacy confirmation, the main variable is prior authorization from your insurance carrier, which typically takes one to two weeks once complete documentation has been submitted. Our team manages that process and keeps you informed throughout. Once authorization is received, we schedule your first session promptly.
