In-office, psychiatrist-led, cash-pay
Ketamine Therapy
A monitored intranasal ketamine program for adults with depression, anxiety, PTSD, OCD, and bipolar depression, delivered in-office under continuous psychiatric supervision, with no take-home medication.
What this is
Ketamine is an anesthetic medication with a decades-long safety record. At lower doses, evidence has grown since the early 2000s that it can rapidly reduce symptoms of depression, anxiety, PTSD, and related conditions, often within hours, and often for people who have not responded to conventional treatments.
Dr. Mike Mah offers compounded intranasal ketamine, administered in-office, under continuous in-room monitoring during the session. The medication is prepared for each patient by a licensed California compounding pharmacy and shipped directly to the office. Patients never handle or transport the medication themselves, and none of it goes home with them.
This is not SPRAVATO® (esketamine), which is a separate FDA-approved medication billed through insurance. Both are intranasal ketamine derivatives. Both have their place. If SPRAVATO is a better fit for you, Dr. Mike Mah will tell you.
Who this is for
The program is designed for adults (18+) whose psychiatric symptoms have not fully responded to standard treatment, or who want to explore ketamine as part of a broader treatment plan. It is appropriate for people with:
- Major depression, including treatment-resistant depression
- Bipolar depression, when stable on a mood stabilizer with a treating psychiatrist
- Severe or generalized anxiety
- PTSD or complex trauma symptoms
- OCD
- Persistent suicidal thoughts, in coordination with your treating provider
Also appropriate for patients already in therapy who feel stuck or want to deepen their work. Ketamine opens a window of neuroplasticity that can make therapeutic insight and change more accessible.
You do not need a diagnosis of "treatment-resistant" anything to be considered. What matters is a careful medical and psychiatric evaluation, an honest conversation about whether ketamine is the right next step, and clear alignment on goals.
When ketamine is not appropriate. Certain conditions make ketamine unsafe or ineffective, including current mania or psychotic symptoms, uncontrolled cardiovascular disease, active substance use disorder involving ketamine or related substances, pregnancy, and specific medication interactions. The evaluation covers this in detail. Dr. Mike Mah will decline to treat if it is not safe, and will help you find the right alternative.
What sets this program apart
Psychiatrist-led
The evaluation, treatment plan, and ongoing decisions are made by Dr. Mike Mah, a board-certified psychiatrist who understands the full mental health picture. This is not a franchise operation or an anesthesiologist-run infusion clinic.
Continuous in-room supervision
A psychiatric nurse practitioner remains in the treatment room with the patient from the first dose through discharge, supervising continuously, holding space, and available in real time. This is a more attentive standard than the “check-in from the next room” model that most cash and Spravato clinics use.
In-office only, no take-home
Every dose is administered and observed in the private treatment room. No take-home ketamine. No mail-order lozenges. No telehealth-only prescribing.
Personalized dosing
The dose is tailored to each patient and adjusted across sessions based on response and tolerability. SPRAVATO, by comparison, is given in fixed doses.
Trauma-informed protocol
For patients with a trauma history, a modified protocol variant with an adjusted starting dose and additional preparation before treatment begins.
Flexible scheduling
Standard induction is twice a week for four weeks. When twice a week is not workable, a once-weekly induction can be arranged.
Prepared, guided, integrated
Every session starts with a brief mindfulness practice and intention-setting. Dr. Mike Mah does not provide ketamine-assisted psychotherapy (KAP) during sessions, but the office has close referral relationships with KAP-trained therapists in the community for patients who want preparation and integration work alongside treatment. Your own therapist is also welcome to join in-office or via Zoom.
Transparent pricing
Fees are on this page. No sticker shock at consult. No hidden package upsells. Cash-only, so the office is not fighting insurance and not surprising patients with denials.
Continuity of care
If Dr. Mike Mah is your treating psychiatrist, this is one thread in a coherent plan. If you were referred by an outside psychiatrist, he keeps them in the loop and coordinates on medications so nothing falls through the cracks.
How a session works
Approximately two hours, arrival to discharge
Check-in
Vital signs, a brief interval check, and a moment to review your intention for the session.
Preparation
Guided mindfulness and intention setting, tailored to each patient. Eye mask provided; bring your own headphones and music. The room is dim, quiet, and private.
Administration
Intranasal ketamine, self-administered under direct supervision. The dose is prescribed in advance by Dr. Mike Mah.
Monitoring
You remain reclined for 60 to 90 minutes. A psychiatric nurse practitioner stays in the room with you the entire time. Vital signs are checked at intervals.
Recovery
A brief check-in once you have returned to baseline. Discharge criteria met.
Pickup
A designated adult accompanies you home. They may drive, or ride with you in a rideshare. You will not drive or operate machinery until the following morning.

Pricing
Cash-pay, payment at the time of service, credit or debit card on file. No insurance is billed for ketamine sessions. On request, the office provides a paid medical receipt suitable for HSA or FSA reimbursement per your plan's rules.
Intake, evaluation & clearance
Psychiatric evaluation with Dr. Mike Mah. The required first visit before treatment sessions can begin. The same flat intake fee whether or not you arrive with clearance from an outside psychiatrist. Referrals from outside providers streamline the visit but do not reduce the fee.
Ketamine treatment session
Approximately 2 hours in-office. Psychiatric nurse practitioner in the room the entire session. Includes medication. Cadence and total number of sessions is determined with Dr. Mike Mah based on response and tolerability.
Card on file is required. Cancellations or reschedules under 48 business hours, or no-shows, are charged a $350 late cancellation/reschedule/no-show fee. Dedicated PMHNP time and prepared medication cannot be redirected on short notice.
For referring providers
Psychiatrists, primary care physicians, and psychotherapists: referrals are welcome. If you have a patient you would like to consider for in-office intranasal ketamine, contact the office and Dr. Mike Mah will send the Referring Psychiatrist Clearance form.
With a completed clearance, your patient's ketamine intake and evaluation is a streamlined clinical visit. You remain your patient's primary psychiatric provider. Dr. Mike Mah coordinates on medications, keeps you updated on treatment response, and does not initiate or adjust psychiatric medications outside the ketamine protocol without discussion.
Frequently asked questions
No. SPRAVATO® is esketamine, an FDA-approved intranasal medication billed through insurance under a REMS (Risk Evaluation and Mitigation Strategy) program, restricted to treatment-resistant depression and depression with acute suicidal ideation. What Dr. Mike Mah offers is compounded intranasal ketamine, an off-label use of a different (though related) molecule, cash-pay, appropriate for a broader range of psychiatric indications, and available without insurance prior authorization. Both are legitimate. If SPRAVATO is the right treatment for you, Dr. Mike Mah will tell you. Many psychiatrists in West Los Angeles offer SPRAVATO.
Intravenous ketamine is the most-studied route. Intranasal ketamine has grown in use because it is less invasive, does not require IV access or an anesthesiologist, and can be dosed more flexibly across sessions. Both routes can be effective. Intranasal is appropriate for most patients seeking outpatient ketamine care. Some patients ultimately do better with IV, and Dr. Mike Mah will refer you to a trusted IV clinic if that is the case.
For ketamine sessions specifically, no. Ketamine treatment is cash-pay. The office does not provide CPT-coded superbills for ketamine, because there is no clean code for compounded intranasal ketamine and Dr. Mike Mah will not use codes designed for other medications. A paid receipt for HSA or FSA reimbursement is provided. For general psychiatric care with insurance, patients can be seen at Century City Psychiatry, Dr. Mike Mah's insurance-based group practice.
No. A designated adult is required to accompany you at discharge. That person can drive you, or can ride with you in a rideshare, but you will not travel home alone. You cannot drive, cycle, or operate machinery until at least the morning after treatment. Please arrange this in advance.
Standard induction is two sessions per week for four weeks (eight sessions), followed by weekly consolidation sessions for about four more weeks, then maintenance every two to four weeks based on your response. A once-weekly induction schedule is also available for patients who can't do twice-weekly: a slower response trajectory, but a legitimate alternative with good evidence behind it.
Ketamine works faster than any traditional antidepressant. Some patients notice a shift within 24 hours of the first session. Most responders show clear improvement within three to four weeks.
We reassess at session eight (around week four). If you're responding, we move to the consolidation and maintenance phases. If you're not, we talk honestly about stopping and discuss alternatives such as SPRAVATO, TMS, ECT, or medication adjustments. We'd rather stop than keep charging for a treatment that isn't working for you.
Almost always, yes. Standard antidepressants (SSRIs, SNRIs, atypicals), mood stabilizers, antipsychotics, and stimulants are all compatible with ketamine. A few specifics worth flagging at your intake:
- MAOIs require an individualized risk-benefit discussion before proceeding.
- Lamotrigine: continue as usual, no interaction.
- Regular benzodiazepines may blunt ketamine's antidepressant effect, and we may hold them on session mornings.
- Cannabis and alcohol: hold for 24 hours before each session.
Bring your full medication and supplement list to your intake visit so we can review everything together.
The psychiatric nurse practitioner will guide a brief mindfulness practice at the start of each session and check in with you afterward, but does not provide psychotherapy during the ketamine experience itself. Patients are strongly encouraged to work with a psychotherapist for preparation and integration around treatment. If you already have a therapist, they are welcome to join in-office or via Zoom during your session with a signed release. If you do not, the office can help connect you with community therapists trained in ketamine-assisted work.
Yes, in most cases. Bipolar depression is a legitimate indication for ketamine treatment, provided you are stable on a mood stabilizer and under the care of a treating psychiatrist. Current mania or a mixed episode is an exclusion. The evaluation covers this carefully.
It depends. An active substance use disorder, particularly involving ketamine, dissociatives, opioids, or stimulants, is a contraindication. A history of substance use in stable recovery, with appropriate support, is often compatible with ketamine treatment. This is a case-by-case conversation with Dr. Mike Mah.
Common and usually short-lived: dissociation (feeling disconnected from your body or surroundings), transient increases in blood pressure and heart rate, nausea, dizziness, and drowsiness. Less common: prolonged perceptual changes, unpleasant emotional experiences, transient cognitive effects. Uncommon but serious: manic activation in vulnerable patients, worsening of psychiatric symptoms, urinary or bladder symptoms with repeated use, and rare cardiovascular events. Full details are reviewed in informed consent, which you receive before you consent to treatment.
The FDA issued a warning in October 2023 about compounded ketamine, primarily focused on at-home and telemedicine-only ketamine where no clinician is present to monitor for adverse outcomes. That warning is a real concern, and it is the reason this program does not send any ketamine home with patients, does not offer telehealth ketamine, and requires every dose to be administered under continuous in-room PMHNP supervision in the office.
No. The practice does not offer an after-hours or on-call phone service. For medical emergencies, call 911 or go to UCLA Ronald Reagan Medical Center. For mental-health crises after hours, call or text 988. For non-urgent questions, contact the office during business hours.
Getting started
Contact the office to schedule an intake. Please have your current medication list, treating psychiatrist's contact information (if applicable), and the name and phone number of the person who will accompany you at discharge.
Plan for about one week between the intake visit and your first treatment session. Compounded ketamine is prescribed for each patient individually and shipped to the office, so the gap reflects standard pharmacy turnaround.
