Insurance guide for TMS & Ketamine treatments

TMS therapy coverage

Most major insurance providers cover Transcranial Magnetic Stimulation (TMS) for treatment-resistant depression in adults. This includes most commercial plans, Medicare, and many Medicare Advantage plans. Medicaid coverage varies by state — some states cover TMS, others have restrictions on age or diagnosis.

Prior authorization is typically required. Insurers generally want documentation showing you have tried at least two antidepressant medications from different drug classes without adequate response, often along with documentation of psychotherapy. Specific requirements vary by plan.

Typical out-of-pocket costs: With insurance and met deductibles, copays per session generally range from $0 to $50. Without insurance, a full TMS course (30-36 sessions) typically ranges from $6,000 to $15,000, though some clinics offer cash-pay packages at lower rates.

Esketamine (Spravato) coverage

Esketamine, sold under the brand name Spravato, is FDA-approved and covered by most major insurers for treatment-resistant depression and for major depressive disorder with acute suicidal ideation or behavior. Spravato can only be administered at REMS-certified clinics — coverage usually requires the clinic to be in your insurer's network.

Prior authorization is standard. Documentation of prior medication trials and treatment-resistant diagnosis is typically required. Janssen Pharmaceuticals (the manufacturer) offers patient support services that may help with the authorization process.

Typical out-of-pocket costs: With insurance, copays per session generally run $50-$300 depending on your plan and whether your deductible is met. Without insurance, sessions typically range from $400 to $900. Janssen's CarePath program may help eligible patients reduce out-of-pocket costs.

IM Ketamine coverage

Intramuscular (IM) ketamine is used off-label for psychiatric conditions — meaning the FDA has not specifically approved ketamine for depression, PTSD, or anxiety, even though it's commonly used for them. Because of this off-label status, IM Ketamine is rarely covered by insurance for psychiatric use.

Some clinics may bill insurance for the medical management component of treatment (e.g., the consultation or monitoring fee), but the medication itself is typically billed to the patient. Verify with the clinic exactly what is and isn't billed to insurance.

Typical out-of-pocket costs: Per-session costs typically range from $300 to $700. A full course of treatment (induction plus initial maintenance) generally ranges from $2,500 to $6,000+. Many clinics accept HSA or FSA payments and partner with healthcare financing companies like CareCredit.

Questions to ask your insurer

Before starting treatment, call the member services number on your insurance card and ask:

• Is this specific treatment covered under my plan?
• What documentation is required for prior authorization, and who submits it — me or the clinic?
• Is the clinic I'm considering in-network or out-of-network?
• What is my deductible, and how much have I met this year?
• What will my copay or coinsurance be per session?
• Is there a limit on the number of sessions covered per year?
• Are there step-therapy requirements (do I need to try other treatments first)?
• What happens if my prior authorization is denied — what's the appeals process?

Document the date, time, and representative's name for each call. Insurance call centers are notorious for inconsistent answers, so having a record helps if you need to dispute a denial later.

Questions to ask the clinic

• Do you accept my insurance, and are you in-network?
• Do you handle prior authorization, or do I need to coordinate that myself?
• What is the typical out-of-pocket cost for this treatment?
• Do you offer payment plans or financing options?
• Do you accept HSA or FSA payments?
• What happens if my insurance denies coverage mid-treatment?
• Are there any additional fees not covered by insurance (e.g., facility fees, consultation fees)?

If insurance won't cover treatment

When insurance coverage isn't available or is denied, several options can reduce out-of-pocket costs:

• Cash-pay rates. Some clinics offer significantly lower self-pay prices than their billed-to-insurance rates. Always ask for the cash price even if you have insurance.
• Manufacturer assistance. For Spravato, Janssen's patient support programs may provide financial assistance for eligible patients.
• HSA / FSA accounts. Health savings accounts and flexible spending accounts can typically be used for these treatments.
• Healthcare financing. Companies like CareCredit offer financing for medical treatments, often with deferred-interest promotional periods.
• Sliding-scale clinics. Some clinics adjust fees based on income. Ask whether financial hardship assistance is available.
• Appeal denied claims. Insurance denials can often be appealed. Many denials are overturned on appeal when supporting clinical documentation is provided. Your clinic's billing team can usually help.
