If you have read that Medicare covers TMS therapy for people aged 55 and over, that is not correct, and it is worth clearing up because the mistake cuts both ways. Some people conclude they are too young to qualify. Others assume that turning 55 makes them automatically eligible. Neither is true.
Medicare does cover transcranial magnetic stimulation for major depressive disorder. Eligibility depends on your diagnosis and on how your depression has responded to previous treatment, not on your age.
Does Medicare cover TMS therapy?
Yes, for major depressive disorder, under defined conditions. Coverage is set out in Local Coverage Determinations issued by the Medicare Administrative Contractors. In California, the relevant policy is LCD L34641, administered by Wisconsin Physicians Service. A parallel policy, LCD L34998 from Novitas Solutions, applies in other jurisdictions.
Neither policy contains an age threshold of any kind. The California policy refers only to treatment of an adult.
The actual eligibility criteria
Under the policy that applies in California, all of the following must be met before Medicare will cover TMS.
A confirmed diagnosis of severe major depressive disorder
The diagnosis must be severe MDD, single or recurrent episode, confirmed against current diagnostic criteria. This matters: the policy was explicitly not extended to moderate depression, on the grounds that the evidence was insufficient.
Evidence of treatment resistance
You need to show one of the following:
- No clinically significant response to one trial of antidepressant medication in the current episode, from at least two different drug classes; or
- An inability to tolerate medication, evidenced by two trials from at least two different drug classes, with distinct side effects; or
- A history of responding to TMS in a previous episode, or current use of electroconvulsive therapy.
A trial of psychotherapy
The California policy also requires a trial of an evidence-based psychotherapy known to be effective for major depression, of adequate frequency and duration, without significant improvement.
An order from a psychiatrist who has examined you
The order for TMS must be written by a psychiatrist, an MD or DO, who has examined you face to face and reviewed your record. A referral from a primary care physician alone does not satisfy this.
What Medicare covers, and for how long
An initial course is covered for up to six weeks. A standard course of TMS for depression usually runs five days a week over four to six weeks, which is roughly 30 to 36 sessions, so the covered period is designed around a full initial course rather than a trial of a few sessions.
Coverage of a repeat course later, if depression returns, is assessed separately and generally depends on having responded to the first one.
Where the idea about age 55 comes from
There is a grain of truth underneath the confusion. Depression is common in older adults and often under-treated, and older patients are more likely to have tried several antidepressants over the years, which is exactly the treatment history the coverage criteria ask for. Older adults are also more likely to have medical conditions or take other medications that make antidepressant side effects harder to tolerate.
So a larger share of people over 55 happen to meet the criteria. That is a pattern in who qualifies, not a rule about who is allowed to. A 38-year-old who has failed two classes of antidepressants and an adequate course of therapy meets the same criteria as a 70-year-old in the same position.
Medicare Advantage plans work differently
If you are enrolled in a Medicare Advantage plan rather than Original Medicare, your plan must cover at least what Original Medicare covers, but it may apply its own prior authorisation process, its own network rules, and its own documentation requirements. Check directly with the plan before starting treatment, and ask specifically whether prior authorisation is required.
How to check your own coverage
- Book a psychiatric evaluation. Coverage turns on a documented diagnosis and treatment history, so this is the step that establishes whether you qualify.
- Bring a list of every antidepressant you have tried, with rough dates, doses and why each was stopped. This is the single most useful thing you can prepare.
- Note any courses of therapy you have completed, and for how long.
- If you are on a Medicare Advantage plan, call the number on your card and ask about prior authorisation for TMS for major depressive disorder.
- Ask the clinic to confirm what your out-of-pocket costs would be, including any deductible or coinsurance.
What TMS involves
TMS uses magnetic pulses delivered through a coil placed against the scalp to stimulate a targeted region of the brain. It is non-invasive, requires no anaesthesia or sedation, and you remain awake throughout. Most people can drive themselves home and return to work the same day.
Session length varies with the protocol. Standard repetitive TMS typically takes 20 to 40 minutes, while accelerated formats can be considerably shorter. The most common side effects are headache and mild twitching of the facial muscles during treatment, both usually mild and short-lived. TMS does not cause memory loss. The most serious potential side effect is a seizure, which is very rare.
TMS devices are cleared by the FDA for major depressive disorder including treatment-resistant depression, for obsessive-compulsive disorder, for short-term smoking cessation support, and for acute treatment of migraine with aura. Medicare coverage, however, is narrower than FDA clearance: the LCDs above cover major depressive disorder specifically.

Frequently asked questions
Is there an age requirement for Medicare to cover TMS?
No. Neither Local Coverage Determination governing TMS contains an age threshold. Eligibility depends on a confirmed diagnosis of severe major depressive disorder and a documented history of treatment resistance.
Does Medicare cover TMS for anxiety or PTSD?
No. Medicare coverage under these policies is for major depressive disorder. TMS for anxiety, PTSD or other conditions is off-label and would not be covered under this pathway.
How many antidepressants do I need to have tried?
Under the California policy, either one trial from at least two different drug classes without clinically significant response, or two trials from at least two classes that you could not tolerate because of distinct side effects.
Do I need to have tried therapy as well?
Under the California policy, yes. It requires a trial of an evidence-based psychotherapy for depression, of adequate frequency and duration, without significant improvement.
How long will Medicare cover treatment?
An initial course is covered for up to six weeks. A repeat course later is assessed separately.
Can my GP refer me for TMS?
Your GP can refer you for a psychiatric evaluation, but the order for TMS itself must be written by a psychiatrist who has examined you in person and reviewed your record.
