Does Insurance Cover Ketamine Therapy? (2026 Guide)

It depends which kind. The FDA-approved nasal spray Spravato (esketamine) is usually covered with prior authorization. Off-label IV ketamine is usually not covered and is paid cash. That single distinction, FDA-approved or not, decides almost everything about your bill. Here is the full picture, and how to lower what you pay either way.

Spravato (esketamine): usually covered

FDA-approved for treatment-resistant depression and given in-office. Medicare (Part B) and most commercial plans cover it with prior authorization. Out of pocket is often modest, but watch for separate observation and facility fees. See the Spravato cost guide.

IV ketamine: usually not covered

Used off-label for depression, so most plans deny it as experimental. You typically pay cash, about $400 to $800 per infusion. HSA/FSA and out-of-network superbills are the main ways to offset it. See the ketamine cost guide.

Why One Is Covered and the Other Is Not

FDA approval creates the coverage pathway. Spravato was FDA-approved for treatment-resistant depression, which gives insurers a basis to cover it. IV ketamine is only FDA-approved as an anesthetic, so using it for depression is off-label and plans class it as experimental.

This is a coverage decision, not a clinical ranking. Studies find the two work about equally well for many patients, with IV ketamine often acting faster. Insured patients are frequently steered to Spravato mainly because it is the option their plan will pay for.

What Each One Costs

Treatment	Insured out of pocket	Cash pay
Spravato (esketamine)	Often $10 to $250/session with the savings card, plus possible separate observation or facility fees	~$750 to $1,100+/session
IV ketamine (off-label)	Rarely covered, so usually full cash	~$400 to $800/session; ~$2,400 to $4,800 per course

Estimates for 2026 from manufacturer, clinic, and industry sources; your plan and site of care drive the real number.

What About Psilocybin and MDMA?

Neither is FDA-approved or covered by insurance yet, though the field is moving quickly.

Psilocybin has reported positive late-stage trial results for treatment-resistant depression, and a company is expected to seek FDA approval around the end of 2026. If approved, coverage would still take time.
MDMA-assisted therapy for PTSD was turned down by the FDA in 2024 and the sponsor has said another trial is needed, so it is not close to approval.
State programs in Oregon and Colorado offer supervised psilocybin sessions, but these are cash-pay (often $1,000 to $3,500+ per session) and not covered by insurance.
Large drugmakers are now entering the space (for example, a multibillion-dollar 2026 acquisition), which is a sign it is maturing, but that does not change today's coverage.

How to Lower What You Pay

Practical steps

If you have treatment-resistant depression and insurance, ask about Spravato first, since it is the covered option, and use the manufacturer savings and observation-rebate programs.
For cash ketamine, pay with an HSA or FSA, request an itemized superbill, and get a Good Faith Estimate before you start.
Appeal a prior-authorization denial with a letter of medical necessity from your prescriber.

Frequently Asked Questions

Does insurance cover ketamine therapy for depression?

Off-label IV ketamine is usually not covered, because it is not FDA-approved for depression. The FDA-approved nasal spray Spravato (esketamine) is generally covered with prior authorization.

Does Medicare cover ketamine or Spravato?

Medicare covers Spravato under Part B (the medical benefit), with prior authorization and about 20% coinsurance unless you have a supplement. Medicare does not cover off-label IV ketamine for depression.

Why is IV ketamine not covered if it works?

Coverage follows FDA approval, not just clinical results. Because ketamine is only FDA-approved as an anesthetic, insurers treat its use for depression as experimental. Spravato has the depression approval, so it has a coverage pathway.

Does insurance cover psilocybin or MDMA therapy?

No. Neither is FDA-approved, so insurance does not cover them. State-regulated psilocybin programs in Oregon and Colorado are cash-pay. This may change if and when the FDA approves them, but not yet.

Can I use my HSA or FSA for ketamine therapy?

Generally yes, when it treats a diagnosed condition. Paying with pre-tax dollars is often the most reliable way to lower the cost of cash ketamine. A letter of medical necessity helps, and your plan administrator decides.
