Add to that the confusing insurance requirements around "treatment resistance," and it's easy to feel stuck before you even start.
This guide breaks down exactly who qualifies for Transcranial Magnetic Stimulation (TMS), what disqualifies someone, and how the team at TMS Center Centennial helps Denver-area patients confirm eligibility, without the guesswork.
Key Takeaways
- TMS is FDA-cleared for adults with major depressive disorder and OCD, plus adolescents 15-21 as an adjunct treatment
- Qualification typically requires a current depressive episode and inadequate response to at least two antidepressants
- Head implants, certain neurological conditions, and active substance abuse can disqualify patients; many factors need case-by-case review
- Only a licensed psychiatrist or medical director can confirm eligibility—a personal consultation beats any online checklist
What Is TMS Therapy?
TMS is a non-invasive treatment that uses magnetic pulses to stimulate the dorsolateral prefrontal cortex. That brain region helps regulate mood and tends to be underactive in people with depression. The FDA first cleared TMS for adult major depressive disorder in 2008.
TMS Center Centennial uses BrainsWay's Deep TMS system, which relies on patented H-Coil technology built into a helmet-shaped device. Unlike earlier-generation figure-8 coils that target a narrower area, the H-Coil reaches broader and deeper neural networks associated with mood and anxiety circuits.
What a session actually looks like:
- No anesthesia or sedation required
- Patients stay awake and can drive themselves home immediately after
- Sessions take about 30 to 45 minutes in the office, depending on the protocol
- A full course typically spans four to six weeks, five days a week
Faster options are also available at TMS Center Centennial for patients whose schedules or clinical needs call for a quicker pace:
- Swift Deep TMS™ compresses a full course into roughly two weeks
- Theta Burst Stimulation shortens each session to about three minutes at no extra cost
Who Qualifies for TMS Therapy? Key Eligibility Requirements
Eligibility isn't a single yes-or-no checkbox. It's a combination of age, diagnosis, and treatment history that a psychiatrist reviews together.
Age and Diagnosis Requirements
Most TMS candidates are adults 18 and older with a confirmed diagnosis of major depressive disorder, including treatment-resistant depression. That said, the field has expanded recently.
In November 2025, the FDA cleared BrainsWay's Deep TMS system as an adjunct treatment for major depressive disorder in adolescents ages 15-21.
That clearance drew on real-world data from over 1,100 adolescent patients treated between 2012 and 2024, using standardized PHQ-9 scores after a full course of sessions.
Whatever your age, the diagnosis has to reflect a current depressive episode. Clinics typically document this using standardized rating scales like the PHQ-9 or HAM-D at intake, then again throughout treatment to track progress.
Treatment History Requirements
This is where most confusion lives. Insurance-defined criteria generally require:
- Inadequate response to at least two antidepressants from different drug classes
- Medications taken at an adequate dose for an adequate duration during the current episode (often six weeks or longer)
- A clear picture of those medication attempts (what you tried, at what dose, and for how long)
A history of psychotherapy is generally required as part of the clinical evaluation as well - you'll just need to tell us who you saw for therapy and roughly when.
If you haven't checked every box on that list, it's still worth reaching out - exceptions do exist, and a more in-depth medical evaluation can often open doors that a general checklist would close.
But there's an alternate path. If you can't tolerate antidepressant side effects, or a medical condition prevents you from taking medication at all, you may still qualify. Intolerance counts just as much as ineffectiveness in most clinical evaluations.
Additional Qualifying Scenarios
TMS isn't only for depression. Adults with OCD who haven't found adequate relief from medication, therapy, or both may qualify for Deep TMS as an FDA-approved adjunct treatment.
No article, including this one, can officially confirm your eligibility. Only a licensed psychiatrist or medical director can do that through a clinical evaluation.
At TMS Center Centennial, Dr. Cheryl Dasler, Psychiatrist, oversees that evaluation.
What Conditions Is TMS Approved to Treat?
The FDA has cleared Deep TMS for a specific, growing list of conditions. Knowing where the line sits matters, especially if you're hoping to use TMS for something outside its cleared scope.
FDA-cleared indications include:
- Major depressive disorder, including treatment-resistant depression (cleared 2013)
- OCD, as an adjunct treatment for adults (cleared 2018)
- Short-term smoking cessation aid for adults (cleared 2020)
- MDD with comorbid anxiety symptoms, sometimes called "anxious depression" (cleared 2021)
- Adjunct treatment for adolescent MDD, ages 15-21 (cleared 2025)
What's not on that list matters too. Generalized anxiety disorder, PTSD, and bipolar depression remain active areas of research rather than official FDA indications.
Studies on PTSD and GAD show encouraging early results, but sample sizes are small and evidence quality is still developing. Eligibility for these conditions depends heavily on provider judgment rather than a standard label.
For off-label concerns, many clinics pair TMS with other modalities. TMS Center Centennial, for example, treats depression, anxiety, PTSD, and OCD in a multidisciplinary model that combines Deep TMS with NeurOptimal neurofeedback and collaborative counseling through licensed therapist Carolyn Riviere.
When PTSD or anxiety is the primary issue—not a core depressive episode—that combined approach often makes more clinical sense than TMS alone.
Things We Need to Know About Before TMS Therapy
Some factors need a closer clinical look. Others are simple session prep. Here's how they break down.
Things we need to know about metal (separate removable items from implanted or permanent metal so they are not confused):
- Removable (earrings, necklaces, hearing aids, hairpins, and similar items around the head and neck): taken off before the session and not a disqualifier.
- Implanted or permanent (need a clinical evaluation): aneurysm clips or coils; cochlear implants; stents; metal within about 30 centimeters of the treatment area; retained bullet fragments or other ferrous metal fragments; tattoos containing inks formulated with metals; deep-brain stimulators, pacemakers, or vagus nerve stimulators.
Neurological factors requiring specialist clearance:
- History of seizures or epilepsy
- Brain tumors
- Traumatic brain injury
- Stroke
Other caution factors:
- Pregnancy or nursing
- Active substance abuse
- Active suicidality
- Psychotic depression, which is often better suited to treatments like ECT
Many of these "caution" items aren't automatic disqualifiers. A prior seizure decades ago, for example, doesn't necessarily rule someone out.
It means a physician needs to weigh the risk individually, which is why a generic online checklist can't replace a real medical screening. TMS Center Centennial's intake process reviews each factor against the patient's medical history before any treatment plan moves forward. Please raise anything you are unsure about during your evaluation.
How TMS Center Centennial Helps You Determine Eligibility
Figuring out eligibility on your own is frustrating. Here's what the process actually looks like when you work with a clinic that does this daily.
- Free consultation. The team reviews your psychiatric history, current medications, and what you've already tried. This first call, reachable at (720) 642-6555, is where most questions get answered.
- Medical evaluation. Dr. Cheryl Dasler, Psychiatrist, confirms diagnosis and screens for contraindications like implants or neurological risk factors.
- Insurance verification. TMS Center Centennial works with most major insurers, including Cigna, Anthem Blue Cross Blue Shield, TRICARE, United Healthcare, and Aetna. The team handles prior authorization paperwork on your behalf.
- Personalized treatment plan. The team builds a schedule around your diagnosis, whether that's standard Deep TMS, Swift Deep TMS, or Theta Burst Stimulation. Clinic-reported outcomes show roughly 89% of patients experience significant symptom reduction and 69% achieve complete remission.
There's also a personal layer to this clinic's approach. Clinical Director Rodney Placzek is a retired Army Sergeant Major who found his own recovery through TMS after military transition, personal loss, and years of struggling with traditional treatment.
That background shapes a genuinely veteran-friendly model, backed by TRICARE acceptance and staff who understand what military families are navigating. According to the Clinical TMS Society, most insurers now cover TMS for eligible patients, which makes that first consultation a lower-stakes step than many people expect.
Frequently Asked Questions
What are the requirements for TMS?
Candidates are generally adults 18+ (or adolescents 15–21 in select cases as adjunct care) with a diagnosis of major depressive disorder or OCD. Your clinician will also confirm an inadequate response to at least two prior antidepressants, with no disqualifying medical conditions.
Who is not eligible for TMS?
People with certain implanted or permanent metal near the head, a history of seizures, active substance abuse, or psychotic depression typically need individualized medical review rather than automatic exclusion. Things we need to know about metal: removable items such as earrings, necklaces, hearing aids, and hairpins are taken off before the session and are not a disqualifier. Implanted or permanent concerns that need evaluation include aneurysm clips, cochlear implants, stents, metal within about 30 centimeters of the treatment area, retained bullet fragments or other ferrous metal fragments, and tattoos containing inks formulated with metals. Pacemakers and other implants remain part of the safety review. Please raise anything you are unsure about during your evaluation.
What conditions is TMS approved for?
The FDA has cleared TMS for major depressive disorder, OCD as an adjunct treatment, smoking cessation, and anxious depression. Conditions like PTSD and generalized anxiety are still under active research.
How long does it take to see results from TMS?
Many patients notice improvement within two to four weeks of starting treatment, though the standard course runs four to six weeks. Full benefit is usually judged after the full course is complete.
Does insurance cover TMS therapy?
Most major insurers cover TMS for treatment-resistant depression, often requiring prior authorization. TMS Center Centennial accepts Cigna, Anthem BCBS, TRICARE, United Healthcare, and Aetna, and manages the authorization process for patients.
Can I continue taking my antidepressants during TMS treatment?
Yes - patients can continue their current medications during TMS, and most do. Staying stable on medications throughout the protocol is encouraged: keeping variables consistent makes it easier for the clinical team to tell what is actually working. If a medication change becomes necessary, it should be made under medical supervision, and preferably after the TMS protocol is complete rather than in the middle of it. Any changes should always involve the prescribing clinician, not be made independently. Your psychiatrist will review your current prescriptions as part of your evaluation and recommend the right plan for your situation.
