TMS and Medicare in 2026: What's Covered and How to Avoid Denials

Everything you need to know about TMS and Medicare in 2026: What's Covered and How to Avoid Denials — how it works, what it costs, and how to find a provider who actually knows what they're doing.

Medicare covers TMS therapy for depression when coverage criteria are met. Coverage is set by regional Medicare Administrative Contractors (MACs) through local coverage determinations (LCDs), so the details can differ by region. If you are on Medicare and struggling with depression that has not responded to treatment, TMS may be a covered option.

But covered does not mean automatically approved. Medicare’s TMS policies still have rules that trip people up. This guide covers what is generally covered, how to avoid denials, and what you will pay out of pocket.

What Medicare Covers Right Now

Major Depressive Disorder (MDD) is the covered indication. Under the Medicare LCDs, coverage generally requires an adult with MDD who has not responded to adequate antidepressant trials from different drug classes (or could not tolerate them), has tried an evidence-based psychotherapy without significant improvement, and is treated with an FDA-cleared or approved device under direct physician supervision. The LCD we reviewed does not set a fixed session count, so confirm with your MAC and clinic what is authorized.

The key phrase is adequate trial. Your treatment history needs to be clearly documented in your medical records, and exact definitions come from your MAC’s LCD.

Retreatment. The LCD allows retreatment for a patient who met the initial criteria, later relapsed, and previously responded (greater than 50% improvement on a standard depression rating scale).

Maintenance TMS is not covered. Medicare TMS LCDs state that maintenance therapy is not considered reasonable and necessary because clinical trial evidence does not currently support it.

OCD and other conditions. The FDA has cleared some TMS devices for OCD (BrainsWay deep TMS, 2018) and other conditions, but the Medicare LCD we reviewed covers MDD only, and it states that deep TMS for OCD is not considered reasonable and necessary. Coverage for anxiety, PTSD, chronic pain and substance use disorders is generally not available through Medicare. Check your MAC’s current LCD.

How to Avoid Denials

TMS denials happen. Here is how to minimize the risk.

Get your medication history documented before the prior auth submission. This is the number one reason for denials. Medicare wants clear evidence that you tried at least one antidepressant at an adequate dose for adequate duration. If your records are scattered across multiple providers, gather them. Ask previous prescribers for treatment summaries. Your TMS provider’s office can help with this, but do not assume they will track down records from a psychiatrist you saw three years ago.

Make sure your depression rating scale score is current. Your TMS provider should administer a standardized scale such as the PHQ-9 at the consultation visit and include it in the documentation.

Use a provider experienced with Medicare billing. Not all TMS clinics handle Medicare regularly, and the billing nuances matter. A clinic that primarily serves commercially insured people may not be up to speed on MAC-specific requirements. You can search our directory and filter for providers who accept Medicare.

Do not skip your sessions. Try to maintain the prescribed schedule, since consistent attendance supports both your outcome and the documentation of medical necessity. If you need to miss sessions, tell your provider’s office so they can document the reason.

Know your appeal rights. If you are denied, you have the right to appeal. For traditional Medicare, you generally have 120 days to request a redetermination, and the contractor generally has 60 days to decide. Denials caused by missing documentation can often be resolved by supplying it. Your TMS provider’s office should be willing to help with appeals. If they are not, consider a different provider.

What You Will Pay Out of Pocket

Medicare Part B covers TMS as an outpatient procedure. After you have met your annual Part B deductible ($283 in 2026), you are responsible for 20% coinsurance on the Medicare-approved amount.

Medicare-approved amounts per session are set by the Physician Fee Schedule and vary by locality, so ask your clinic for the allowed amount for your area and multiply by 20% for your estimated share of a full course.

If you have a Medicare Supplement (Medigap) plan, it may cover some or all of that 20% coinsurance. Many standard Medigap plans (for example Plans G and F) cover Part B coinsurance. Check your specific plan.

Medicare Advantage (Part C) plans set their own cost-sharing rules. Some have lower coinsurance for TMS. Others have higher. Some require referrals or use narrower provider networks. Call your plan directly and ask about TMS cost-sharing before starting treatment.

The Medicare Advantage Wrinkle

This deserves its own section because it confuses a lot of people.

If you have a Medicare Advantage plan (from UnitedHealthcare, Humana, Aetna, and others), your TMS coverage is governed by your plan’s specific policies, not traditional Medicare’s. MA plans must cover what traditional Medicare covers, but they can impose additional requirements: prior authorization procedures, network restrictions, step therapy protocols, or different cost-sharing amounts.

The practical upside: some MA plans have lower out-of-pocket costs than traditional Medicare for TMS. The practical downside: some have more restrictive authorization requirements, and the appeal process can be more cumbersome.

Always verify coverage with your specific MA plan before starting treatment. Get the authorization in writing. And make sure your TMS provider is in-network. Out-of-network TMS with a Medicare Advantage plan can mean paying the full cost yourself.

Finding a Medicare-Friendly TMS Provider

Not every TMS clinic accepts Medicare. Reimbursement rates are often lower than commercial insurance, and some practices do not accept Medicare. Before you get emotionally invested in a particular clinic, confirm that they are a participating Medicare provider.

Search our provider directory to find TMS clinics in your area that accept Medicare. You can also call your local MAC (Medicare Administrative Contractor) for a list of participating TMS providers in your region.

Once you have identified a provider, ask these specific questions at your consultation:

• Do you accept Medicare assignment?
• Will you handle the prior authorization?
• How many Medicare TMS patients have you treated?
• What is your denial rate, and do you help with appeals?
• Do you offer theta burst stimulation?

A clinic that confidently answers all of these has likely been through the Medicare TMS process many times before. That experience translates directly into a smoother process for you.
