Deep TMS is FDA-cleared for OCD in adults who have not responded adequately to medication and therapy. It uses the H7 coil to stimulate the medial prefrontal cortex and anterior cingulate, with a brief symptom provocation before each session. The course is about 29 sessions over six weeks. In the pivotal trial, 38 percent of patients responded versus 11 percent on sham.
Stedfast Psychiatry offers Deep TMS for OCD at Palm Beach Gardens. The OCD protocol uses a different coil than the depression protocol, targets a different circuit, and begins each session with a brief symptom provocation. This page explains how it works, what the trial that led to clearance showed, and who is a candidate.
Who it is for
Deep TMS for OCD is cleared as an adjunct treatment for adults with OCD, meaning it is added to, not substituted for, your existing medication and therapy. Candidates have typically tried at least one or two SSRIs at the high doses OCD requires, often with clomipramine or an antipsychotic augmentation, and have completed or attempted exposure and response prevention therapy, with symptoms that remain moderate to severe on the Yale-Brown Obsessive Compulsive Scale. People with OCD and depression together are common and are good candidates; the H7 protocol has shown benefit for both. TMS is not a first-line OCD treatment and is not a replacement for therapy, which remains the most durable intervention. Contraindications are the same as for depression: metal in the head, implanted devices, and seizure history.
How it works
OCD involves overactivity in a loop connecting the orbitofrontal cortex, anterior cingulate cortex, striatum and thalamus. Where depression treatment targets the left dorsolateral prefrontal cortex, OCD treatment targets the medial prefrontal cortex and dorsal anterior cingulate, structures on the midline that sit deeper than a figure-8 coil can reach. The H7 coil was designed for this target. Stimulation at 20 Hz is delivered at 100 percent of the leg motor threshold, since the leg motor area is adjacent to the target. The distinctive feature of the OCD protocol is symptom provocation: before each session the technician spends three to five minutes deliberately triggering your obsessions, using a personalized script developed with your psychiatrist, so that the circuit being treated is active when stimulation begins. The pivotal trial showed that stimulation during provocation produced significantly better results than stimulation alone, consistent with the principle that TMS modifies circuits most effectively when they are engaged.
In the pivotal multicenter trial of 99 patients with treatment-resistant OCD, 38.1 percent of those receiving active Deep TMS responded at six weeks versus 11.1 percent on sham, and 45.2 versus 17.8 percent at one-month follow-up.

What to expect
The OCD course is five sessions a week for six weeks, about 29 sessions in total, with each session taking about 25 minutes including provocation. On day one we measure your leg motor threshold and build your provocation script: a list of specific triggers, from contamination cues to intrusive thoughts to checking urges, rated by how much distress they cause. Each session begins with the technician presenting triggers until your distress reaches a moderate level, then the 18-minute stimulation begins. Your Y-BOCS score is tracked weekly. Improvement typically appears in weeks three to five and continues after the course ends; in the trial, response rates were higher at one-month follow-up than at the end of treatment.
Benefits
- The first and most studied FDA-cleared device treatment for OCD
- Adds to medication and therapy rather than replacing them
- No systemic side effects, no sedation, drive yourself
- Benefit continued to grow in the month after the course ended in the pivotal trial
- Treats comorbid depression alongside OCD in many patients
Risks and side effects
Headache was the most common side effect in the OCD trial, reported by about a third of patients in both the active and sham groups, which suggests much of it came from sitting still with a helmet rather than from stimulation. Scalp discomfort and facial twitching are expected. The provocation step causes temporary distress by design; it is brief, it is controlled, and most patients find it comparable to a therapy exposure. Seizure risk is in the same rare range as the depression protocol, under 0.1 percent per course. No cognitive side effects were observed.
Cost and insurance
Coverage for TMS for OCD is less uniform than for depression. A growing number of commercial plans cover it, typically after documented failure of two SSRI trials at adequate dose and a course of exposure and response prevention, with a Y-BOCS score of 20 or higher. Other plans still classify it as investigational, and Medicare in Florida does not currently cover TMS for OCD. Our TMS coordinator will check your plan and, where coverage is denied, pursue an appeal citing the FDA clearance and published evidence. For self-pay, ask our TMS coordinator for current self-pay rates.
Why OCD needed a new treatment
Standard OCD care is an SSRI at a dose higher than used for depression, continued for at least 12 weeks before judging response, plus exposure and response prevention therapy. SSRIs help 40 to 60 percent of patients, and the typical improvement is a 20 to 40 percent reduction in symptoms, not remission. Clomipramine is somewhat more effective but harder to tolerate. Adding an antipsychotic helps about a third of non-responders. ERP is the most effective treatment, but it requires a trained therapist, significant time and the willingness to confront feared situations repeatedly. After all of that, a substantial minority of patients are still severely impaired. Before 2018 the next option was deep brain stimulation, a neurosurgical procedure. Deep TMS fills the gap between medication and surgery.
The Carmi trial
The evidence that produced the clearance is a multicenter, double-blind, sham-controlled trial published in the American Journal of Psychiatry in 2019 by Lior Carmi and colleagues. Ninety-nine adults with OCD who had failed at least one SSRI trial were randomized to active or sham Deep TMS with the H7 coil, 20 Hz, five sessions a week for six weeks, each preceded by individualized symptom provocation. At six weeks, 38.1 percent of the active group had responded, defined as a 30 percent or greater drop in Y-BOCS, versus 11.1 percent of the sham group. At one-month follow-up the figures were 45.2 versus 17.8 percent. The mean Y-BOCS reduction was 6.0 points on active treatment versus 3.3 on sham. Adverse events were similar between groups, with headache the most common.
What real-world data add
A 2021 post-marketing analysis in the Journal of Psychiatric Research pooled 219 patients treated at 22 clinics with the H7 protocol in ordinary practice. After 29 sessions, 58 percent met the response criterion and 72 percent had at least a partial response, defined as a 20 percent Y-BOCS reduction. Average time to response was about 20 sessions. These figures are higher than the trial, which is typical for open-label registries, and they suggest that completing the full course matters.

Building your provocation script
On day one, you and your psychiatrist list the obsessions and compulsions that drive your OCD and rate each on a 0 to 10 distress scale. Contamination fears might be provoked by touching a doorknob or looking at an image of a public restroom. Harm obsessions might be provoked by reading a sentence describing the feared outcome. Checking might be provoked by being told the stove may have been left on. The technician uses the script to raise your distress to about 4 to 7 out of 10 before stimulation starts, then asks you to resist any compulsion during the session. The script is adjusted as your symptoms change, and it often doubles as a map for exposure therapy afterward.
Combining TMS with your existing OCD care
You continue your SSRI or clomipramine throughout the course. If you are in ERP therapy, we coordinate with your therapist so that exposures continue; many patients find exposures easier during and after TMS. If you have not done ERP, we recommend starting it, and we can connect you with ERP-trained therapists in Palm Beach County. Stedfast's psychiatrists manage your medication and your TMS course together, so dose changes and TMS scheduling are coordinated by one team.

Frequently asked questions
Does TMS work for OCD?
Yes, for a meaningful share of patients who have not responded to medication and therapy. In the pivotal trial, 38 percent responded to active Deep TMS versus 11 percent to sham, rising to 45 percent a month later. Real-world data from 22 clinics showed 58 percent reaching response after a full course. OCD is a stubborn condition and TMS is not a cure, but it is the only device treatment with FDA clearance and a positive randomized trial.
How is the OCD protocol different from the depression protocol?
Three ways. It uses the H7 coil, which targets the medial prefrontal cortex and anterior cingulate rather than the left dorsolateral prefrontal cortex. It is dosed against the leg motor threshold rather than the hand. And each session begins with a personalized symptom provocation so that the OCD circuit is active during stimulation. The course is slightly shorter, about 29 sessions over six weeks, without a taper phase.
What is symptom provocation and why is it needed?
Symptom provocation means deliberately triggering your obsessions for three to five minutes before stimulation. You and your psychiatrist build a script of triggers, from images and words to touching a feared object. The goal is moderate distress, not panic. The pivotal trial compared stimulation with and without provocation and found that provocation produced significantly better results, because TMS modifies a circuit most effectively while that circuit is engaged.
Can I do TMS instead of exposure therapy?
We do not recommend it. Exposure and response prevention remains the most effective and durable OCD treatment, and TMS was cleared as an adjunct, not a replacement. The best outcomes come from combining them: TMS appears to make the brain more responsive to exposure work. If you have tried ERP and found it intolerable, TMS may lower your symptoms enough to make therapy feasible, and we can connect you with ERP-trained therapists.
Will TMS help my OCD and my depression at the same time?
Often. Most OCD patients have significant depressive symptoms, and the H7 protocol has shown improvement in depression scores alongside OCD scores in trial and registry data. If depression is your more severe problem, your psychiatrist may recommend the depression protocol first. If OCD dominates, the OCD protocol usually addresses both. In some cases we sequence the two protocols.
Does insurance cover TMS for OCD?
Some commercial plans do, usually after two SSRI trials at OCD-level doses and a course of exposure and response prevention, with a documented Y-BOCS score of 20 or higher. Other plans still consider it investigational, and Florida Medicare does not cover it. Our TMS coordinator checks your plan before you commit and pursues appeals where coverage is denied. Self-pay is available; ask our coordinator for current rates.
How long do the results last?
The trial followed patients for one month after treatment and found that response rates continued to rise during that month, suggesting the effect consolidates after the course ends. Longer-term data are limited. Many patients maintain improvement for months to years, particularly when they continue medication and apply ERP skills. If symptoms return, a shorter retreatment course can be given.
