What Is Ketamine-Assisted Psychotherapy — and How Is It Different from Ketamine Infusions?

Ketamine has moved from anesthetic to one of the most discussed tools in psychiatry — but not all ketamine treatment is the same. The distinction between ketamine-assisted psychotherapy (KAP) and standalone ketamine infusions matters clinically, and it matters for patients trying to decide what kind of care they actually want.

What Ketamine-Assisted Psychotherapy Is

Ketamine-assisted psychotherapy, commonly abbreviated as KAP, pairs ketamine administration with structured psychotherapy sessions. The two components are not incidental to each other — the therapy is timed deliberately around the treatment, because ketamine produces a period of heightened neuroplasticity (the brain’s capacity to form new connections and patterns) that psychotherapy can work within. Research supports that this combination may produce more durable and meaningful outcomes than ketamine alone (National Center for Biotechnology Information).

At Cohen & Associates, KAP is delivered by Teri Callender, LCSW, PA-C, a psychiatric physician assistant and licensed clinical social worker who holds specific certification in ketamine-assisted psychotherapy. That certification matters. The integration of psychotherapy into ketamine treatment requires clinical training in both pharmacology and therapeutic technique — it is not simply a medication session with a check-in afterward.

How the Mechanism Works

Ketamine acts on the glutamate system — the brain’s primary excitatory neurotransmitter network — by blocking NMDA receptors. This mechanism is distinct from how traditional antidepressants work. SSRIs and SNRIs target serotonin and norepinephrine; ketamine targets a different pathway entirely, which is part of why it can produce effects in patients who have not responded to conventional medications (National Center for Biotechnology Information).

One of the downstream effects of this NMDA receptor activity is a surge in neuroplasticity. The brain becomes temporarily more receptive to forming new neural connections — new patterns of thought, emotional processing, and behavioral response (National Center for Biotechnology Information). Psychotherapy is designed to capitalize on exactly that window. When therapy is woven into the treatment course rather than offered separately, patients have a structured opportunity to work through the material that the ketamine experience surfaces.

How KAP Differs from a Ketamine Infusion Clinic

A ketamine infusion clinic administers the medication intravenously, typically in a series of sessions, and monitors the patient medically during and after each infusion. Some clinics offer a separate therapist referral; others do not. The medical benefit of infusions is real, and for some patients they are appropriate. But the therapeutic integration is not built into that model by default.

At Cohen & Associates, we do not offer standalone IV ketamine infusions. What we offer is a psychotherapy-centered approach in which the ketamine component — administered as nasal ketamine treatment — is embedded within a broader therapeutic relationship. This is not a minor procedural distinction. The research suggesting that KAP may outperform ketamine alone in terms of treatment durability points to the integrated relationship as the active variable (National Center for Biotechnology Information). Patients who come to us are not just receiving a medication; they are receiving a structured therapeutic process.

We also offer SPRAVATO® (esketamine nasal spray), the FDA-approved treatment for treatment-resistant depression, which is available through certified healthcare settings and requires medical supervision. SPRAVATO® and KAP serve different patient needs and involve different clinical protocols; our team can clarify which applies to your situation during an evaluation.

Who Is a Good Candidate for KAP

Ketamine-assisted psychotherapy may be worth exploring for patients who have treatment-resistant depression, persistent anxiety, or PTSD that has not fully responded to standard medications or conventional therapy. That said, KAP is not appropriate for everyone, and a comprehensive psychiatric evaluation is required before any treatment begins. Medical history, current medications, and overall psychiatric presentation all factor into candidacy.

For patients who feel emotionally stuck — who have tried medication adjustments and different therapists without finding lasting traction — KAP offers a different mechanism and a different therapeutic frame. It is not a last resort. It is a clinically grounded option with a growing evidence base, offered by providers with the specific training to deliver it properly.

Results vary by individual. We do not make outcome guarantees, and any discussion of treatment should include an honest conversation with your provider about what the evidence supports for your specific presentation.

Addressing the Cost and Access Question

We operate on a direct-care model, which means we do not bill insurance and do not accept insurance payments. Visits are paid at the time of service by debit/credit card, check, or cash. Patients may be partially reimbursed through their insurance provider as out-of-network care, and we provide invoices for that purpose upon request. Specific pricing for KAP is not listed on our website; we discuss costs transparently during the consultation process before any commitment is made.

We understand that cost is a real factor in whether people can access advanced psychiatric care. We believe the direct-care model — in which insurance companies are not intermediaries in treatment decisions — ultimately serves patients better, but we do not dismiss the financial question. Bringing it up during your consultation is appropriate and expected.

FAQ

Is ketamine-assisted psychotherapy the same as recreational ketamine use?

No. Ketamine administered in a clinical setting at therapeutic doses, under medical supervision, and integrated with structured psychotherapy is categorically different from recreational use. The dose, setting, intent, and clinical monitoring are all distinct. Johns Hopkins Medicine notes ketamine has been used safely in medical settings for decades.

How many sessions does KAP involve?

The number of sessions varies by patient and treatment plan. A comprehensive psychiatric evaluation comes first, and the protocol is built around individual needs rather than a fixed number. We discuss the treatment course in full before beginning.

Can KAP be combined with my current medications?

Potentially, yes — but this depends on your specific medication history and psychiatric profile. Some patients continue existing medications alongside KAP; others adjust under medical supervision. This is a clinical decision made on a case-by-case basis during your evaluation.

Do I need a referral to be seen at Cohen & Associates?

No referral is required. You can contact our office directly to schedule a new patient evaluation with one of our clinicians.

Is KAP covered by insurance?

We do not bill insurance directly. Patients may receive partial out-of-network reimbursement depending on their plan. We provide documentation to support that process.

Key Takeaways

• Ketamine-assisted psychotherapy integrates structured therapy sessions with ketamine treatment — it is not the same as a standalone infusion.
• The therapeutic window created by ketamine’s neuroplasticity effects is the mechanism that makes the psychotherapy integration clinically meaningful.
• At Cohen & Associates, KAP is delivered by a certified provider with dual training in psychiatric care and ketamine-assisted therapy.
• KAP may be appropriate for patients with treatment-resistant depression, anxiety, or PTSD who have not responded to standard treatment approaches.
• Results vary by individual; a comprehensive evaluation is required before any treatment begins.

For patients who have tried the standard options and are looking for something with a different mechanism and a clinical rationale behind it, ketamine-assisted psychotherapy may be worth a conversation. At Cohen & Associates, that conversation starts with a thorough evaluation — not a sales pitch.
