Ketamine Therapy Cost: Pricing by Type, Insurance Coverage, and What to Expect

Ketamine therapy for depression typically costs $400 to $800 per IV infusion, so the standard initial series of six infusions over two to three weeks runs $2,400 to $4,800 before maintenance boosters. Most insurers do not cover IV ketamine for depression because that use is off label, while Spravato (esketamine nasal spray), the FDA-approved form for treatment-resistant depression, is often covered after prior authorization.

Ketamine therapy has gone from a niche psychiatric intervention to a widely available treatment in a short period of time. That expansion brought wide pricing variation and marketing that does not always make clear what you are paying for. A clinic charging $600/session and one charging $1,200/session may be offering very different levels of care, or nearly the same care at different price points driven by location and overhead.

A price only makes sense next to the delivery method, the protocol, the monitoring and the evidence behind it, so the sections below take each of those in turn and end with how to judge whether a specific clinic's pricing reflects genuine value. For a complete overview of how ketamine works and which conditions have the strongest evidence, see our Ketamine Therapy Guide.

How Much Does Ketamine Therapy Cost for Depression?

Ketamine for depression costs $400 to $800 per IV infusion at most US clinics, and $2,400 to $4,800 for the usual first series of six infusions. Intramuscular (IM) ketamine injections run $200 to $500 per session. At-home sublingual ketamine prescribed by telehealth costs $200 to $400 per month. Spravato, the esketamine nasal spray, is the one option that insurance commonly pays for.

The total depends on three things: which delivery method you use, how many maintenance sessions you need after the first series, and whether the clinic bundles psychiatric evaluation and integration therapy into its fee. The ketamine therapy treatment guide explains how the drug acts on NMDA receptors and glutamate signaling, and the broader depression treatment overview shows where ketamine sits next to antidepressants, psychotherapy, TMS and ECT.

Cost by Delivery Method

Ketamine reaches the bloodstream in five common ways, and each one carries a different price, protocol, insurance status and level of medical supervision. The table compares them side by side.

The clinic-based routes (IV, IM and Spravato) cost more per session because a licensed clinician watches you during and after each dose. The home routes cost less per dose, but the dose that reaches the bloodstream is less predictable and nobody is monitoring blood pressure or dissociation while you take it.

IV Infusion: The Standard and Its Costs

IV ketamine remains the most studied delivery method and the one most clinics use as the benchmark protocol for treatment-resistant depression (TRD), bipolar depression, PTSD, and chronic pain. The sub-anesthetic dose is typically 0.5 mg/kg infused over 40 minutes, though protocols vary by clinic and indication.

The standard initial series is 6 infusions over 2-3 weeks, which costs $2,400-$4,800 for the series alone. After the initial series, most patients who respond need booster infusions at intervals ranging from monthly to quarterly to maintain the response. For a good responder on quarterly boosters, annual maintenance adds $1,600-$3,200/year on top of the initial series.

The fee should include the ketamine medication itself (inexpensive as a generic), IV line placement, monitoring during the infusion (continuous pulse oximetry, blood pressure checks, a nurse or provider present), and time in a recovery area for 30-60 minutes post-infusion. Many clinics also include pre-infusion psychiatric assessment in the initial consultation fee ($150-$300) and provide integration support resources, though dedicated integration therapy sessions typically cost extra.

How much does a ketamine infusion cost for chronic pain?

Ketamine infusions for chronic pain usually cost more per session than depression infusions, because pain protocols for conditions such as complex regional pain syndrome (CRPS), fibromyalgia and neuropathic pain often use longer infusions and higher total doses, which means more chair time and staff time. Anesthesiologists and pain medicine physicians run most of these protocols. The chronic pain treatment guide covers the alternatives, and our post on ketamine for chronic pain reviews the evidence by condition.

Spravato (Esketamine): The Insurance Path

Spravato is the S-enantiomer of ketamine administered as a nasal spray. The FDA approved it in 2019 for treatment-resistant depression (defined as failure of two adequate antidepressant trials) and in 2020 for depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior. In January 2025 the FDA expanded the TRD indication to include use as monotherapy, without an oral antidepressant alongside it, according to the agency's supplemental approval letter.

Because it is FDA-approved for depression, Spravato is the ketamine-class treatment that insurers most often cover, subject to formulary rules and prior authorization. Commercial plans and Medicare can cover it for approved indications, which makes it the most accessible ketamine option for insured patients with TRD. No insurer is obliged to cover it for every patient, so coverage depends on your plan and documented treatment history.

Spravato is administered under the REMS (Risk Evaluation and Mitigation Strategy) program, which requires that patients receive it in a certified healthcare setting and be monitored for at least 2 hours after each dose. It cannot be taken home and self-administered. Patient cost-sharing after insurance typically runs $10-$100/session for patients with commercial insurance who have met their deductible, but out-of-pocket can reach $600-$900+ per session for patients with high deductibles or high coinsurance.

Does Insurance Cover Ketamine Infusions?

Insurance rarely covers IV ketamine infusions for depression, because generic ketamine is FDA-approved only as an anesthetic, and its use for depression, PTSD or anxiety is off label. Most ketamine infusion clinics are therefore cash pay. Spravato is the main exception, and some plans reimburse parts of the visit around an infusion even when the infusion itself is not covered. Our separate post on ketamine therapy and insurance goes deeper into plan types.

How do you get Spravato approved by insurance?

1. A prescriber documents a diagnosis of major depressive disorder and at least two adequate antidepressant trials that did not work, which is the FDA definition of treatment-resistant depression.
2. The prescriber or the treatment center submits a prior authorization request with that history to your plan.
3. You receive the drug at a REMS-certified treatment center, which bills the drug and the observation time, sometimes under different parts of your benefit.
4. If the plan denies the request, the prescriber can appeal with additional records, such as pharmacy fills and chart notes that show each prior antidepressant trial.

Can you use an HSA, FSA or superbill for ketamine?

Out-of-pocket ketamine treatment prescribed for a diagnosed condition generally counts as a medical expense that a health savings account (HSA) or flexible spending account (FSA) can pay, under the medical care definition in IRS Publication 502. Confirm with your plan administrator before you pay. Some clinics also provide a superbill, an itemized receipt with diagnosis and procedure codes, that you can submit for partial out-of-network reimbursement of the psychiatric evaluation or office visit.

At-Home Ketamine Telehealth

Several telehealth companies offer ketamine prescriptions for sublingual troches (lozenges) that patients take at home. A prescribing provider conducts a virtual assessment, a compounding pharmacy ships the troches, and the platform provides digital support materials. Costs typically run $200-$400/month in subscription form.

The trade-offs are concrete: sublingual bioavailability for ketamine is about 20-30%, compared to 100% for IV. The dose reaching your bloodstream at therapeutic timing is less predictable. There is no medical monitoring during the session. Most telehealth platforms do not provide integration therapy; they provide app-based guided sessions that substitute for it.

For patients with mild-to-moderate depression who have not tried ketamine before and want a lower-cost entry point, telehealth troches are a reasonable starting option to discuss with a clinician. For treatment-resistant cases or significant psychiatric history, IV at a clinic with psychiatric oversight is the more appropriate choice.

Geographic Price Variation

Ketamine clinic pricing correlates strongly with real estate and local healthcare market costs. In major metropolitan areas (New York, Los Angeles, San Francisco, Chicago), expect to pay $600-$800 per IV infusion. In mid-sized cities and suburban markets, $400-$600 is more typical. In rural areas or lower cost-of-living markets, $350-$500 is possible.

This variation reflects overhead, not efficacy. The ketamine itself costs roughly $5-$20 per dose as a generic. What you are paying for is the facility, monitoring staff, provider time, and the clinical infrastructure. A higher-priced clinic is not necessarily delivering a better ketamine experience, but it may be providing better psychiatric integration, more robust monitoring, or more experienced practitioners.

To compare local options, start with the state lists for ketamine clinics in California, Texas or Florida, then ask each clinic for its per-infusion price and what that price includes.

Who Provides Ketamine Therapy, and How That Affects Price

Ketamine clinics are run by several kinds of clinicians, and the clinic model shapes both price and what you get for it. Anesthesiologists and certified registered nurse anesthetists (CRNAs) run many infusion clinics and bring airway and sedation expertise. Psychiatrists and psychiatric nurse practitioners run others and bring diagnostic assessment and medication management. Emergency physicians and pain medicine physicians also operate infusion clinics.

An anesthesia-led clinic may price lower per infusion but refer out for psychiatric care, while a psychiatry-led clinic may charge more and include evaluation and follow-up. Ketamine-assisted psychotherapy (KAP), where a licensed therapist works with you before, during and after dosing, costs more again because it adds therapist time. The psychedelic therapy guide explains how KAP relates to psilocybin and MDMA research.

Does Ketamine Work? The NNT Data

For treatment-resistant depression specifically, ketamine has some of the strongest short-term response data in psychiatry. Response rates (50%+ reduction in depression scores) within 24 hours of the first infusion run 50-70% across major studies. This rapid onset is unusual; SSRIs take 4-8 weeks to show effect.

The Number Needed to Treat (NNT) for ketamine in TRD is estimated at approximately 5-7 for short-term response, meaning that for every 5 to 7 patients treated with ketamine instead of a comparison condition, one additional patient responds. For comparison, the NNT for SSRIs in non-resistant depression is commonly put at 7-9 for a partial response. Ketamine’s NNT advantage narrows or disappears for maintenance at 6-12 months, where the durability data is weaker.

Murrough et al., 2013 (American Journal of Psychiatry, a two-site RCT of 73 patients randomized 2:1, with 47 receiving ketamine) compared a single IV ketamine infusion to midazolam as an active placebo in TRD. Response rate at 24 hours was 64% for ketamine vs. 28% for midazolam. This remains one of the landmark controlled trials in the field.

A larger head-to-head trial followed. In ELEKT-D, Anand et al. (New England Journal of Medicine, 2023) randomized 403 patients with nonpsychotic TRD to IV ketamine or electroconvulsive therapy, and 55.4% of the ketamine group responded compared with 41.2% of the ECT group, which met the trial's test for noninferiority.

Comparison to Other TRD Treatments

IV ketamine and ECT cost about the same for an initial series, while transcranial magnetic stimulation (TMS) costs more up front but is more often covered by insurance. For Spravato, the ESCAPE-TRD trial by Reif et al. (New England Journal of Medicine, 2023) found remission at week 8 in 27.1% of patients on esketamine compared with 17.6% on extended-release quetiapine, each added to an SSRI or SNRI. Our comparisons of TMS versus ketamine and Spravato versus IV ketamine go further, and the TMS treatment guide covers protocols and coverage rules.

What Will Ketamine Treatment Cost in the First Year?

The first year of IV ketamine for depression typically costs $4,000 to $8,000 for someone who responds and continues on quarterly boosters. That figure combines the $2,400-$4,800 initial series with $1,600-$3,200 of maintenance infusions, plus a one-time consultation of $150-$300 at clinics that charge for it separately. The table adds up the main paths using the prices stated above.

Integration therapy adds $150-$250 per session if you choose it. Patients who do not respond after the initial series usually stop there, so the series price is also the cost of finding out whether ketamine helps you.

Red Flags in Ketamine Clinic Pricing

Pricing red flags that suggest a clinic is cutting corners: no psychiatric evaluation before starting (ketamine is contraindicated in active psychosis and uncontrolled hypertension); no monitoring during infusions; sessions shorter than 35-40 minutes (sub-therapeutic for depression); pressure to pre-purchase large session packages without a trial; no protocol for what happens if you have a difficult dissociative experience.

Pricing red flags in the other direction: clinics charging $1,500+ per IV infusion without being able to articulate what is included beyond the standard monitoring. Integration therapy bundled at high prices without clarity on credentials of the integration provider. Wellness add-ons (IV vitamins, NAD+ co-infusions) priced on top of an already premium session fee without evidence they improve ketamine outcomes.

What Should Be Included in the Cost

A well-priced ketamine infusion at $500-$700 should include: psychiatric or medical intake evaluation; pre-infusion vital signs and IV placement; the infusion itself with continuous monitoring by a licensed clinician present; post-infusion recovery time with monitoring until you meet discharge criteria; and a follow-up check-in (in person or by phone) after your first session.

Integration therapy (processing the psychological content of ketamine experiences) is best practice but is often not included in the base fee. It is also not strictly required to get antidepressant benefit from ketamine, which is primarily a neurobiological effect rather than a psychedelic processing effect. Budget an additional $150-$250/session if you choose to work with a therapist specializing in integration.

What should you ask a ketamine clinic before paying?

1. What does the per-infusion price include, and which items (consultation, integration, add-ons) are billed separately?
2. Who places the IV, who is in the room during the infusion, and who decides when you can go home?
3. What dose and infusion length does the clinic use for your condition, and how does it adjust them?
4. Can you pay per session for the first series instead of buying a package, and what is the refund policy?
5. Does the clinic coordinate with your psychiatrist or therapist, and will it provide a superbill?

How to Compare Ketamine Clinics on Regenerated.com

The national directory of ketamine therapy clinics lists infusion clinics, psychiatry practices and Spravato treatment centers by state and city, and Regenerated.com is free for patients to use. Listing order is not paid ranking. Featured slots are labeled and capped, and Verified means a clinic completed credential checks, not that it spent more. Inclusion in the directory is not an endorsement, so use the list to build a shortlist and then put the questions above to each clinic.

The guide to Featured, Verified and organic listings explains each label in detail. If you are comparing ketamine with magnetic stimulation, the TMS clinic directory uses the same rules.

The Bottom Line

Ketamine therapy costs $400 to $800 per IV infusion and $2,400 to $4,800 for a first series, which makes it expensive relative to oral medications and comparable in cost to other neuromodulation treatments for TRD. For the right patient (failed 2+ adequate antidepressant trials, significant functional impairment), the speed and size of the short-term response data make a reasonable case for the cost, though durability beyond a few months is less certain. For patients with insurance-eligible TRD, Spravato is the most financially accessible ketamine-class option. For those without insurance coverage and with the means to pay out of pocket, IV infusion at a supervised clinic remains the most evidence-backed delivery method.

Frequently Asked Questions

How much does ketamine therapy cost per session?

Ketamine therapy costs $400 to $800 per IV infusion session at most US clinics. IM injections run $200 to $500, and Spravato (esketamine nasal spray) carries a patient cost-share of $600 to $900 or more per session for people with high deductibles. At-home sublingual troches cost $50 to $150 per dose, or $200 to $400 per month by subscription. Location matters too, from $350 to $500 in rural areas up to $600 to $800 in major metros such as New York, Los Angeles, San Francisco and Chicago.

What does a full course of ketamine treatment cost?

A full initial course of IV ketamine is typically 6 infusions over 2 to 3 weeks and costs $2,400 to $4,800. Patients who respond often continue with boosters, and quarterly boosters add roughly $1,600 to $3,200 per year, bringing a typical first year to $4,000 to $8,000. Integration therapy, if you add it, runs an extra $150 to $250 per session, and some clinics charge $150 to $300 for the first consultation.

Does insurance cover ketamine therapy?

Insurance usually covers Spravato, the FDA-approved esketamine nasal spray, for treatment-resistant depression and for major depressive disorder with acute suicidal ideation or behavior, after prior authorization. IV ketamine infusions and at-home ketamine are used off label for depression, so most plans do not cover them and patients pay out of pocket. HSA or FSA funds and superbills for out-of-network reimbursement can offset part of the cost.

How well does ketamine work for depression?

Across major studies, 50 to 70 percent of patients with treatment-resistant depression respond within 24 hours of a first IV infusion. In the Murrough et al. (2013) trial, 64 percent responded to ketamine versus 28 percent to midazolam at 24 hours, and in ELEKT-D (2023) 55.4 percent responded to ketamine versus 41.2 percent to ECT. The advantage narrows for maintenance at 6 to 12 months, where durability data is weaker.

What conditions is ketamine therapy used for?

Ketamine therapy is used mainly for treatment-resistant depression, and clinics also use it off label for bipolar depression, PTSD, anxiety and chronic pain conditions such as CRPS and fibromyalgia. Spravato, the esketamine nasal spray, is FDA-approved for treatment-resistant depression and for major depressive disorder with acute suicidal ideation or behavior. Evidence is strongest for depression and thinner for the other uses, so ask a clinician how the data apply to your condition.

Is at-home ketamine as effective as IV at a clinic?

At-home ketamine is not equivalent to IV ketamine at a clinic. Sublingual troches have roughly 20 to 30 percent bioavailability compared with 100 percent for IV, so the dose that reaches the bloodstream is less predictable, and no one monitors you during the session. For treatment-resistant depression or a significant psychiatric history, IV ketamine at a clinic with psychiatric oversight is the more appropriate choice than a telehealth subscription.
