Your treatment path

How do you get to a treatment-resistant diagnosis?

Care isn't one straight line. Here's how the path branches — and when first-line treatment isn't enough, what your options are.

Comprehensive evaluation
History, symptoms, goals, and what's been tried before.
First-line treatment
Therapy and/or medication, matched to your diagnosis.
After 6–8 weeks — is it working?
If it's helping ✓
Continue & maintain
Ongoing medication management, therapy, and follow-up to protect your progress.
If it hasn't helped enough ✗
Treatment-resistant depression or anxiety
When two adequate trials — right dose, enough time — haven't worked, that's treatment-resistant.
What are the options now?

Frequently Asked Questions (FAQ)

Answers to common questions about psychiatric consultation, TMS therapy, Spravato (esketamine), and treatment-resistant depression at Exxceed Wellness in Hayward, CA. This is general education, not medical advice for your specific situation. If your question isn't answered here, please contact us.

General Psychiatric Care

What conditions does Exxceed Wellness treat?

We provide psychiatric care for depression and treatment-resistant depression, anxiety, OCD, and ADHD. Alongside medication management, we offer two interventional treatments, TMS and Spravato (esketamine), for depression that hasn't responded to standard care.

What happens at a first psychiatric consultation?

Your initial visit is a thorough evaluation. We review your history, current symptoms, past treatments, and goals, then discuss the options that fit your situation and build a treatment plan together. It is a conversation, not a quick screening.

Do you see patients in person or by telehealth?

Both. Our clinic is at 21297 Foothill Blvd, Ste 203, Hayward, CA, where in-office treatments such as TMS and Spravato are provided. In-person visits are by appointment only and we do not accept walk-ins. We also see patients by secure telehealth across California for services that can be delivered remotely, including consultations and medication management.

Do you provide medication management?

Yes. Starting, adjusting, and monitoring psychiatric medications is a core part of our care - on its own or alongside TMS or Spravato.

Do I need a referral to be seen?

No. You can schedule directly with our practice. A referral from another provider is welcome but not required.

TMS Therapy

What is TMS, and what conditions is it FDA-cleared to treat?

Transcranial magnetic stimulation (TMS) uses focused magnetic pulses to stimulate the brain regions involved in mood regulation. It is non-invasive, medication-free, and done in the office. TMS is FDA-cleared for major depression (including treatment-resistant depression), anxious depression, and, as an adjunct, OCD; our Magstim Horizon 3.0 carries these clearances. More detail: our TMS therapy page and TMS for OCD.

Does TMS hurt, and how many sessions will I need?

Most patients describe TMS as a tapping or knocking sensation on the scalp rather than pain; mild scalp discomfort is the most common side effect. A typical course is five sessions per week for about six weeks (roughly 30 to 36 sessions), followed by an individualized taper. More detail: what TMS actually feels like.

How long does a single TMS session take?

Active treatment can run from about 3 minutes with newer theta-burst (iTBS / Express) protocols to roughly 20 to 40 minutes for standard protocols. With check-in and setup, plan for a short in-office visit each time. More detail: how long a TMS session takes.

What is the difference between standard rTMS and iTBS?

Standard rTMS uses a figure-8 coil to target a focused area. iTBS, or theta-burst, is a faster stimulation pattern that delivers treatment in just a few minutes. We match the protocol to your diagnosis and coverage. More detail: theta burst and iTBS explained and deep TMS compared with standard rTMS.

Does insurance cover TMS in California?

TMS is often covered by California commercial plans for treatment-resistant depression, typically when there is a documented history of antidepressants that did not work. Plans generally require prior authorization, and we manage that process for you. More detail: California parity law and TMS coverage, how TMS prior authorization works, and plan guides for Aetna, Cigna, UnitedHealthcare, Anthem Blue Cross, and Medicare.

What happens after I finish my TMS course?

Many people maintain their improvement after completing a course of TMS. For others, occasional maintenance sessions or a relapse-prevention plan help protect the gains. We talk through what makes sense based on how you respond. More detail: maintenance and relapse prevention and coverage for maintenance or re-treatment.

Am I a candidate for TMS?

TMS is generally considered when depression has not improved after at least two antidepressant trials taken at an adequate dose for an adequate length of time. Candidacy also depends on your diagnosis, medical history, and safety screening, including metal implants near the head and any seizure history. We review all of this at your evaluation. More detail: who is a candidate for TMS and what counts as an adequate antidepressant trial.

How long does TMS take to work?

Most people who respond begin noticing change during the middle weeks of the course rather than in the first few sessions, and improvement often continues for a period after the final treatment. Response varies from person to person, and some people do not respond. We track symptoms with rating scales throughout so progress is measured rather than guessed. More detail: how long TMS takes to work.

What are the side effects of TMS?

The most common side effects are scalp discomfort at the treatment site and headache, which usually ease within the first week or two. TMS does not require sedation or anesthesia and does not carry systemic medication side effects such as weight gain or sexual dysfunction. Seizure is a rare risk, which is why screening beforehand matters. More detail: TMS side effects and what to expect.

How much does TMS cost, and what if you are out of network with my plan?

For most patients with commercial insurance or Medicare, TMS is billed to insurance rather than paid out of pocket, so what you owe depends on your deductible, copay, and coinsurance. We verify your benefits before you begin so the expected cost is clear in advance. If we are out of network with your plan, a superbill may allow partial reimbursement. More detail: TMS cost in California and out-of-network superbills.

What happens if my insurance denies TMS?

A denial is frequently a documentation issue rather than a final answer. Most denials turn on whether the record clearly shows enough medication trials at an adequate dose and duration. California law also gives you appeal rights, including independent medical review. We prepare and submit the appeal paperwork for you. More detail: how TMS appeals work in California and how long approval usually takes.

Does TMS treat OCD or anxiety?

TMS is FDA-cleared as an adjunct treatment for OCD in adults, and there is a separate clearance for anxious depression, meaning depression that occurs with prominent anxiety. That is not the same as treating generalized anxiety on its own, and insurance rules differ by condition. More detail: TMS for OCD, TMS for anxious depression, and whether insurance covers TMS for OCD.

TMS or Spravato: how do I choose, and can I do both?

The right choice depends on your treatment history, schedule, transportation, and how you tolerate each option, rather than on a fixed ranking. Some people are candidates for both, and in selected cases the two are used in sequence or together. We talk through the tradeoffs with you before deciding. More detail: TMS compared with Spravato and whether TMS and Spravato can be combined.

What if TMS does not work for me?

Not responding to TMS does not mean you are out of options. The next step depends on whether you had a partial response, no response, or stopped the course early, and may involve adjusting the protocol, moving to a different interventional treatment, or revisiting your medication strategy. More detail: what to do if TMS did not work and what happens if neither TMS nor Spravato works.

Spravato & Ketamine

Do you offer ketamine therapy?

We offer Spravato (esketamine), an FDA-approved nasal-spray form of ketamine for treatment-resistant depression, given under monitoring in our clinic. We do not provide IV, intramuscular, or compounded oral ketamine. If you are researching ketamine for depression, Spravato is the ketamine-class treatment available here. More detail: our Spravato page and how esketamine works in the brain.

Is Spravato the same as ketamine?

Spravato is esketamine, the S-enantiomer of ketamine. It is FDA-approved specifically for treatment-resistant depression and is given as a nasal spray in a certified setting. This differs from racemic IV ketamine, which is used off-label for depression. More detail: how esketamine works in the brain.

How does a Spravato session work, and how long does it take?

You self-administer the nasal spray in our office under supervision, then stay for monitoring. Because of how Spravato can affect you, you are observed for at least two hours after each dose, so plan for roughly two to two and a half hours per visit. More detail: what to know before your first session.

Can I drive after a Spravato session?

No. You cannot drive for the rest of the day after each Spravato session, so you will need to arrange a ride home. More detail: dissociation, monitoring and planning your schedule.

How many Spravato sessions will I need?

The induction phase is typically twice a week for about four weeks. After that, sessions are spaced out into an individualized maintenance schedule based on your response. More detail: who is a candidate for Spravato.

Is Spravato covered by insurance?

Spravato is often covered for treatment-resistant depression with prior authorization. We help manage the prior-authorization process and verify your benefits before treatment begins. More detail: how Spravato prior authorization works, how to verify your benefits, and plan guides for Aetna, Cigna, UnitedHealthcare, Anthem Blue Cross, and Medicare.

Am I a candidate for Spravato?

Spravato is FDA-approved for treatment-resistant depression in adults, meaning depression that has not improved after at least two antidepressant trials at an adequate dose and duration, and for depressive symptoms in adults with major depression and acute suicidal thoughts or behavior. It is taken alongside an oral antidepressant rather than instead of one. Candidacy also depends on blood pressure, medical history, and whether you can arrange not to drive afterward. More detail: who is a candidate for Spravato and what counts as an adequate antidepressant trial.

How does Spravato actually work in the brain?

Esketamine acts on the glutamate system, a different pathway from the serotonin-focused mechanism of most antidepressants. That difference is why it can help some people who have not responded to standard medications. Response still varies between individuals. More detail: how esketamine works in the brain.

What is dissociation, and should I be worried about it?

Some people feel detached, floaty, or as though time is moving differently during a session. This is a recognized, usually short-lived effect that typically settles within about two hours, which is exactly why you stay in the office and are monitored. Blood pressure is also checked because it can rise temporarily. Tell us what you experience so we can adjust. More detail: dissociation, panic and planning your schedule.

How much does Spravato cost, and what if you are out of network with my plan?

For most patients with commercial insurance or Medicare, Spravato is billed to insurance rather than paid out of pocket, so your share depends on your deductible, copay, and coinsurance. There can be separate charges for the medication and for the monitoring visit. We verify benefits before you begin. If we are out of network, a superbill may allow partial reimbursement. More detail: Spravato cost in California and out-of-network superbills.

What happens if my insurance denies Spravato?

Spravato almost always requires prior authorization, and most denials come down to whether the record documents enough prior antidepressant trials at an adequate dose and duration. Denials can be appealed, and California gives you appeal rights including independent medical review. We prepare the paperwork. More detail: what insurers require in California and how long approval usually takes.

Can I stay on my antidepressant, and can I do Spravato and TMS?

Yes to the first: Spravato is designed to be used together with an oral antidepressant, not as a replacement. As for combining interventional treatments, some people are candidates for both Spravato and TMS, either in sequence or together in selected cases. That decision depends on your history and response. More detail: whether TMS and Spravato can be combined and using both for treatment-resistant depression.

Spravato or TMS: which should I try first?

Neither is automatically first. Spravato requires in-office monitoring and someone to drive you home; TMS requires more frequent visits over several weeks but no sedation or driving restriction. Treatment history, schedule, transportation and coverage all factor in. More detail: TMS compared with Spravato and how the schedule and side effect profile differ.

What if Spravato does not work for me?

A limited or absent response does not mean you are out of options. Next steps depend on how many sessions you completed and whether there was any partial improvement, and may include adjusting the oral antidepressant, moving to TMS, or revisiting the diagnosis. More detail: what to consider if Spravato did not work and what happens if neither Spravato nor TMS works.

Treatment-Resistant Depression

What is treatment-resistant depression?

Treatment-resistant depression generally means depression that has not improved after at least two different antidepressants taken at an adequate dose for an adequate length of time (often 6 to 8 weeks each). Only a clinician can determine this, so the best next step is an evaluation rather than self-diagnosis.

Spravato or TMS: which is right for me?

There is no one-size-fits-all answer. The right choice depends on your treatment history, lifestyle, side-effect tolerance, insurance coverage, and clinical judgment. In some cases the two can be sequenced or combined under clinical supervision. We help you weigh the options during a consultation.

What should I do if my depression starts coming back after treatment?

A returning symptom is a signal, not a setback to face alone. Reaching out early, when sleep, energy, or mood first start to slip, gives us the most options, from adjusting your plan to considering maintenance treatment. Contact us promptly if you notice warning signs.

Anxiety, OCD & ADHD

Can you help with anxiety?

Yes. We treat anxiety with evidence-based options, including medication such as SSRIs, SNRIs, or buspirone and structured therapy approaches. TMS is not FDA-cleared for generalized anxiety, though it is sometimes considered off-label; we discuss what fits your situation.

Do you treat OCD?

Yes. OCD care combines psychiatric medication management, evidence-based ERP (exposure and response prevention) therapy delivered by telehealth, and, for OCD that hasn't responded to those, focal TMS on our Magstim Horizon 3.0 (FDA-cleared as an adjunct for OCD; this is not BrainsWay's Deep TMS). We determine the right approach based on your symptoms and history.

Do you offer ADHD assessment and treatment?

Yes. We provide comprehensive adult ADHD evaluations using a clinical interview, validated rating scales, and history, in our Hayward office or by California telehealth, along with treatment and medication management when appropriate.

Fees, Insurance & Getting Started

Do you accept insurance?

We work with a range of insurance providers, and interventional treatments like TMS and Spravato are often covered for treatment-resistant depression with prior authorization. Coverage varies by plan, so we verify your benefits before your appointment. You can also read how to verify your benefits before starting TMS or Spravato.

What if I do not have insurance?

We offer flexible self-pay options and will discuss costs upfront so you can make an informed decision about your care. See our guide to TMS therapy cost in California.
