Is Ketamine Infusion Covered by Insurance? What to Know in 2026

Short answer: In most cases, IV ketamine infusions for depression, anxiety, or PTSD are not directly covered by insurance, because this use is considered "off-label." Even so, many patients still offset the cost. Some use out-of-network reimbursement with a superbill, some bill related visits such as consults, labs, and follow-ups, and some choose the FDA-approved nasal spray Spravato, which insurers are far more likely to cover. The right answer depends entirely on your specific plan, so it is worth checking before you assume the door is closed.

Below, we walk through why coverage works this way, the difference between IV ketamine and Spravato, what Medicare and Medicaid do and do not cover, and exactly how to find out what your own plan will pay.

Why most insurers do not cover IV ketamine infusions

Ketamine has been approved by the FDA since 1970, but as an anesthetic, not as a treatment for depression or other mental health conditions. When a clinician uses IV ketamine for treatment-resistant depression, anxiety, PTSD, or chronic pain, they are prescribing it "off-label."

Off-label prescribing is legal, common, and often supported by research. But insurers tend to reserve coverage for uses that carry the formal approval of the FDA. Because IV ketamine for mental health does not yet have that specific approval, most commercial plans classify the infusions themselves as not covered.

That is the general rule. It is not the whole story.

IV ketamine versus Spravato (esketamine): the coverage difference

This is the single most important distinction to understand, because the two are treated very differently by insurers.

Spravato (esketamine) is a nasal spray derived from ketamine. The FDA approved it on March 5, 2019 for treatment-resistant depression in adults, in conjunction with an oral antidepressant, and later for depressive symptoms in adults with major depressive disorder who have acute suicidal ideation or behavior. Because it is approved by the FDA for these specific psychiatric uses, most major commercial insurers, Medicare, and many state Medicaid programs cover Spravato when eligibility criteria are met. It must be administered in a certified healthcare setting under a federal safety program (REMS) and is a Schedule III controlled substance.

IV ketamine infusions use generic ketamine off-label. They are often praised for flexible dosing and the ability of the clinician to tailor treatment, but because the psychiatric use is not approved by the FDA, the infusions are usually not directly reimbursed.

So if insurance coverage is your top priority, Spravato may be the more accessible path. If IV infusions are recommended for your situation, coverage is still possible but typically works through reimbursement rather than direct billing. Which treatment is appropriate for you is a clinical decision, something to discuss with a licensed provider.

Does Medicare cover ketamine infusions?

Generally, no. Original Medicare (Parts A and B) does not cover IV ketamine infusions for mental health conditions. Some Medicare Advantage (Part C) plans may offer limited coverage when medical necessity is well documented and other treatments have failed, but this is the exception.

Spravato is different. Medicare Part B can cover esketamine (Spravato) for treatment-resistant depression when it is administered in a certified setting, and Medicare Advantage and Part D may cover it for eligible patients.

Does Medicaid cover ketamine treatment?

For IV ketamine infusions, the answer is usually no. Medicaid programs generally do not cover off-label IV ketamine for mental health. Coverage of Spravato through Medicaid varies by state. Some state Medicaid programs cover it for treatment-resistant depression when criteria are met, others do not. Because Medicaid is administered state by state, you will need to check your specific state's plan.

How patients actually get ketamine therapy partly covered

Even when the infusion itself is not a covered benefit, there are several realistic ways to reduce what you pay out-of-pocket.

Out-of-network reimbursement with a superbill. If your plan includes out-of-network benefits, common with PPO and POS plans, you can pay the clinic directly and then submit a superbill, an itemized receipt with diagnosis codes, procedure codes, and your provider's identifiers, to your insurer. Depending on your plan's out-of-network deductible and "usual and customary" rates, you may be reimbursed for a portion of the cost. Reported reimbursement commonly lands in the 20% to 50% range, though your result depends on your specific plan. Note that many insurers require superbills to be submitted within a window, often 30 to 90 days, so do not sit on them.

Billing the surrounding services. While the infusion may not be covered, some clinics bill insurance for related services such as the initial psychiatric consultation, lab work, and follow-up visits.

Every dollar counts toward your deductible. Out-of-network amounts you submit typically apply toward your annual out-of-network deductible and out-of-pocket maximum, which can lower your share of all out-of-network care later in the year.

Consider Spravato if coverage is the priority. As noted above, the FDA-approved nasal spray is far more likely to be a covered benefit.

A note for Marina del Rey and West Los Angeles patients

Ketamine Uplift is based in Marina del Rey and sees patients from across West Los Angeles and Southern California. Many people in our community carry PPO plans through employers in entertainment, tech, and other industries, and those plans often include out-of-network mental health benefits. That makes the superbill route worth investigating for a lot of our patients. Coverage rules for off-label ketamine are set mostly at the federal and individual-plan level rather than by California specifically, so two people living a block apart can have very different benefits depending on their employer and plan. The only way to know yours is to check it directly.

How to check what your plan covers

Call the member services number on the back of your insurance card and ask:

• Do I have out-of-network outpatient mental health benefits?

• What is my out-of-network deductible, and how much of it have I met this year?

• What percentage do you reimburse for out-of-network outpatient services, and based on what "usual and customary" rate?

• Is there a session limit or a prior authorization requirement?

• Which CPT and ICD-10 codes do you expect on a superbill, and how do I submit it?

• For Spravato specifically: is it covered under my medical or pharmacy benefit, and what are the eligibility criteria?

Write down a reference number for the call. Then confirm the correct codes with your clinician before submitting.

The bottom line

IV ketamine infusions are usually not covered by insurance because the psychiatric use is off-label, but "not covered directly" is not the same as "no help available." Between out-of-network reimbursement, billable surrounding services, and the FDA-approved Spravato alternative, many patients find a workable path. The most useful next step is simply to verify your own benefits.

Frequently asked questions

Is ketamine infusion covered by insurance?
In most cases, IV ketamine infusions for mental health are not directly covered by insurance because the use is off-label. However, patients with out-of-network benefits (often PPO plans) may receive partial reimbursement by submitting a superbill, and some related services may be billable. Coverage depends on your specific plan.

What is the difference between ketamine infusions and Spravato for insurance?
IV ketamine is used off-label and is usually not covered directly. Spravato (esketamine) is approved by the FDA for treatment-resistant depression, so most commercial insurers, Medicare Part B, and many state Medicaid programs cover it when eligibility criteria are met.

Does Medicare cover ketamine infusions?
Original Medicare generally does not cover IV ketamine infusions for mental health. Some Medicare Advantage plans may offer limited coverage with documented medical necessity. Medicare Part B can cover Spravato when administered in a certified setting.

Does Medicaid cover ketamine treatment?
Medicaid generally does not cover off-label IV ketamine infusions. Coverage of Spravato through Medicaid varies by state. Because Medicaid is administered state by state, check your specific state's plan.

How can I get ketamine therapy partly covered by insurance?
If you have out-of-network benefits, you can pay the clinic and submit a superbill for possible partial reimbursement (commonly 20% to 50%, depending on your plan), usually within a 30 to 90 day window. Some clinics also bill related services like consultations, labs, and follow-ups, and submitted amounts can count toward your deductible.
