How Much Does Ketamine Therapy Cost in 2026?
By the TMS Nearby editorial team · Reviewed June 12, 2026
Ketamine therapy — delivered as IV infusions or intramuscular (IM) injections — is used off-label for depression, PTSD, and anxiety. Because the FDA hasn't approved generic ketamine for psychiatric use, insurance rarely covers it, and most patients pay cash.
A typical treatment plan starts with an induction series of about six sessions over two to three weeks, followed by occasional maintenance boosters.
Typical ketamine therapy costs
IV infusions cost more than IM injections because they require continuous monitoring and infusion equipment. At-home oral ketamine programs exist at lower price points, but in-clinic treatment with medical monitoring is the standard most psychiatric organizations recommend.
| Scenario | Typical cost |
|---|---|
| IV infusion, per session | $400 – $700 |
| IM injection, per session | $300 – $500 |
| Induction series (6 sessions) | $2,500 – $4,500 |
| Maintenance booster | $300 – $600 per session |
| First year total (induction + maintenance) | $3,500 – $8,000+ |
Why insurance rarely covers ketamine
Generic ketamine is FDA-approved as an anesthetic, not as a psychiatric treatment. That off-label status means most insurers decline to cover the infusions themselves.
Some clinics can bill insurance for parts of your care — the psychiatric evaluation, medication management visits, or monitoring — which can shave hundreds of dollars off the total. Always ask what the clinic can bill versus what you'll pay directly.
If you want an insurance-covered option in the same family, Spravato (esketamine) is FDA-approved for treatment-resistant depression and is covered by most major insurers.
How to reduce what you pay
- Compare clinics — pricing for the same IV protocol can vary by $200+ per session within one metro area.
- Ask whether the evaluation and follow-up visits can be billed to insurance separately from the infusions.
- Use HSA/FSA funds, which generally apply to ketamine treatment.
- Ask about package pricing for the induction series.
- Consider Spravato if you have insurance — your out-of-pocket cost may be a fraction of cash-pay ketamine.
Frequently asked questions
Does insurance ever cover ketamine infusions?
Rarely. Because ketamine is used off-label for psychiatric conditions, most insurers decline coverage for the infusion itself, though portions of care like evaluations and monitoring visits can sometimes be billed. Spravato (esketamine) is the insurance-covered alternative.
How many ketamine sessions will I need?
Most protocols start with six sessions over two to three weeks. Patients who respond typically return for maintenance boosters every few weeks to few months, based on symptom return.
Is at-home ketamine cheaper?
Yes — oral at-home programs often run $100–$250 per session. However, they involve lower doses, less monitoring, and have drawn regulatory scrutiny. In-clinic treatment remains the better-studied option.
