Ketamine Therapy Cost in 2026, and How to Actually Lower It
IV ketamine therapy for depression is used off-label, so most insurance will not cover it. Expect roughly $400 to $800 per infusion, or about $2,400 to $4,800 for a starting course of six. The realistic ways to bring that down are an HSA or FSA, billing the evaluation visit, and being smart about out-of-network claims, not counting on full reimbursement.
- Ketamine is FDA-approved as an anesthetic, but its use for depression is off-label, so insurers usually treat it as experimental and deny it. You typically pay cash.
- An HSA or FSA is usually the most reliable way to save, because it lets you pay with pre-tax dollars. A letter of medical necessity from your prescriber helps.
- If you have treatment-resistant depression and insurance, the FDA-approved nasal spray Spravato is usually covered and may cost far less out of pocket. It is worth comparing.
What You Actually Pay
Cash prices vary widely by city and clinic. These are estimates from clinic and industry sources, not payer data.
| What | Typical cost |
|---|---|
| Single IV infusion | ~$400 to $800 |
| Starting course (6 infusions) | ~$2,400 to $4,800 |
| Paid with HSA or FSA | save ~20 to 35% |
| Out-of-network superbill | partial, inconsistent |
Why It Is Not Covered, and What Can Still Be Billed
Usually denied
- The infusion and monitoring itself, because using ketamine for a mood disorder is off-label
- The drug line, which is a low-cost generic and reimburses only a dollar or two anyway
Sometimes billable
- The office evaluation or psychiatric visit, which is the most valuable part of a superbill
- These claims go to your plan as out-of-network, so reimbursement depends on your benefits
A minority of plans in a few markets have covered IV ketamine for depression. It is worth calling your insurer to ask, but expect a no in most cases.
How to Lower the Cost
Pay with an HSA or FSA
Ketamine therapy for a diagnosed condition is generally an eligible expense, so paying with pre-tax dollars lowers your effective cost. Ask your prescriber for a letter of medical necessity, and confirm with your plan administrator.
Ask for an itemized superbill and submit it out of network
Request a superbill that lists the evaluation visit separately. Submit it to your plan for possible out-of-network reimbursement. Be realistic: many plans pay little or nothing, so treat any reimbursement as a bonus, not the plan.
Get a Good Faith Estimate first, and hold them to it
As a cash-pay patient you are entitled to a Good Faith Estimate before treatment. If the final bill comes in at least $400 above that estimate, you can use the federal patient-provider dispute process to challenge it.
If you have insurance and TRD, compare Spravato
For treatment-resistant depression, the FDA-approved nasal spray Spravato is usually covered and can cost far less out of pocket than cash ketamine. See the Spravato cost guide.

Does insurance cover ketamine therapy?
Usually not. IV ketamine for depression is off-label, so most plans deny it as experimental. A few plans in some markets are exceptions. The FDA-approved version, Spravato, is generally covered with prior authorization.
How much does ketamine therapy cost?
Roughly $400 to $800 per infusion, with a starting course of six running about $2,400 to $4,800. Prices are higher in major metro areas. Most patients pay cash.
Can I use my HSA or FSA for ketamine therapy?
Generally yes, when it is for a diagnosed condition. Paying with pre-tax HSA or FSA dollars is often the most reliable way to save. A letter of medical necessity helps, and your plan administrator has the final say.
Will a superbill get me reimbursed?
Sometimes, partially, but it is inconsistent. A superbill lets you submit the evaluation visit for out-of-network reimbursement, but many plans pay little or nothing for off-label ketamine. Submit it, but do not build your budget around it.
Is Spravato cheaper than cash ketamine?
For insured patients with treatment-resistant depression, usually yes, because Spravato is covered while cash ketamine is not. Out of pocket can be far lower, though Spravato has its own billing quirks. Compare both in our coverage guide.
