Medicare covers mental health therapy, but the number of sessions is not fixed—it depends on your specific plan and the type of therapy you need

Medicare Part B covers outpatient mental health services, including individual therapy with a psychologist, clinical social worker, or psychiatrist. There is no annual limit on the number of sessions you can have. However, Medicare requires that each session be medically necessary, meaning your doctor or therapist must document that treatment is needed to address a diagnosed mental health condition.

What you pay out of pocket varies. After you meet your Part B deductible (which changes yearly), you typically pay 20 percent of the approved amount for each session. If you have a Medigap or Medicare Advantage plan, your cost-sharing may be lower or work differently. The key is that Medicare itself does not say "you get 10 sessions" or "you get 52 sessions"—instead, coverage continues as long as the treatment remains medically necessary and your doctor orders it.

Key Takeaways

  • Medicare Part B covers individual therapy with no set session limit, as long as your doctor documents that each session is medically necessary.
  • You pay 20 percent of the Medicare-approved amount per session after meeting your Part B deductible, unless you have a Medigap or Medicare Advantage plan that changes your costs.
  • Group therapy and psychiatric medication management are also covered, but have their own cost-sharing rules.
  • Your therapist must be enrolled in Medicare and accept Medicare payment for you to use your Part B coverage.
  • Medicare Advantage plans may limit sessions or require prior approval from the insurance company before you start therapy.

What Medicare Part B Actually Covers

Medicare Part B pays for mental health treatment provided by a licensed professional in an outpatient setting. This includes individual therapy (also called psychotherapy), psychiatric evaluation and management, and psychological testing when ordered by a doctor. The therapist or psychiatrist must be enrolled in Medicare and must accept Medicare payment.

The sessions do not have to happen in a therapist's office. Medicare covers telehealth mental health visits, which means you can have therapy by video or phone from home. This became a permanent option during the pandemic and remains available now. Your therapist can bill Medicare for these visits the same way they bill for in-person appointments.

Group therapy is also covered under Part B, and you pay the same 20 percent coinsurance. Some people find group therapy helpful for conditions like depression or anxiety, and it may be offered through community mental health centers or private practices.

How the "Medically Necessary" Rule Works in Practice

Medicare does not pre-approve a set number of sessions. Instead, your doctor or mental health provider must order treatment and document in your medical record why it is needed. Common reasons include depression, anxiety, post-traumatic stress, adjustment disorders, and other diagnosed mental health conditions. The provider notes the diagnosis, the treatment plan, and how often you need to be seen.

If you see a therapist regularly—say, once a week for six months—Medicare expects your provider to review your progress and confirm that continued treatment is still necessary. If you stop improving or your condition stabilizes, your provider may recommend ending therapy or reducing the frequency of sessions. Medicare may deny payment for sessions that appear to be ongoing without clear medical reason.

In practice, this means you should not worry about "running out" of sessions. As long as your therapist documents that you need treatment and you are making progress or managing a chronic condition, Medicare will continue to cover it. The limit is clinical judgment, not a number.

What You Pay: Deductibles and Coinsurance

Your out-of-pocket cost depends on where you are in the year and what type of Medicare plan you have. Under Original Medicare (Part A and Part B), you pay your Part B deductible once per year. In 2024, that deductible is $240, but it changes yearly. Once you meet it, you pay 20 percent of the Medicare-approved amount for each therapy session.

The Medicare-approved amount varies by location and provider. A therapist in a rural area may have a lower approved amount than one in a city. You can ask your therapist's office what the approved amount is for your zip code, and they can tell you roughly what 20 percent will cost you per session.

If you have a Medigap plan (supplemental insurance), it typically covers your 20 percent coinsurance, so you pay little or nothing per session after the deductible. If you have a Medicare Advantage plan, your costs work differently—you may have a copay per visit instead of coinsurance, or your plan may require prior approval before you start therapy. Check your plan documents or call the plan to find out.

Medicare Advantage Plans and Prior Approval

If you are enrolled in a Medicare Advantage plan (Part C), mental health coverage is included, but the rules are set by your insurance company, not by Medicare. Some Advantage plans require you to get prior approval before starting therapy, meaning your doctor must submit a request to the plan and get permission before your first session. Other plans do not require this.

Many Medicare Advantage plans also limit the number of sessions per year or require you to see a therapist in their network. For example, a plan might cover 30 therapy sessions per year, or it might say you can only see therapists employed by a specific mental health organization. These limits vary widely by plan and by year, so you need to check your specific plan's mental health benefits.

If your Advantage plan denies coverage for a session your doctor ordered, you have the right to appeal. Your therapist's office can help you file an appeal and provide documentation of medical necessity.

Finding a Therapist Who Accepts Medicare

Not all therapists accept Medicare, even if they are licensed. Some have decided not to enroll in Medicare or have stopped accepting Medicare patients. Before you schedule an appointment, ask the therapist's office directly: "Do you accept Medicare?" and "Are you enrolled in Medicare?" This is the fastest way to confirm.

You can also search for Medicare-enrolled providers on the Medicare.gov provider search tool. Go to Medicare.gov, click "Care Provider Search," and look for mental health professionals in your area. The search will show you who is enrolled and accepting new patients, though the list is not always up to date, so calling to confirm is still a good idea.

Community mental health centers often accept Medicare and may have lower costs or sliding-scale fees if you may have access to. Your primary care doctor can refer you to a mental health provider, or you can call your state's mental health department for a list of providers in your area.

What Happens If Medicare Denies a Session

If Medicare denies payment for a therapy session, your provider will send you a notice called an Explanation of Benefits (EOB). This notice explains why the claim was denied. Common reasons include: the provider is not enrolled in Medicare, the session was not ordered by a doctor, or Medicare determined the session was not medically necessary.

You can appeal a denial. Your therapist's office can file the appeal on your behalf, or you can file it yourself. The appeal process takes time—usually several weeks—but you have the right to challenge the decision. If you disagree with the appeal result, you can request a hearing before a Medicare administrative law judge.

In the meantime, ask your therapist's office whether you are responsible for the bill if the claim is denied. Some providers will wait for the appeal result before billing you; others may bill you upfront. Clarifying this in advance prevents surprises.

Frequently Asked Questions

Does Medicare cover therapy for marriage counseling or life coaching?

No. Medicare only covers therapy for diagnosed mental health conditions like depression, anxiety, or trauma. Marriage counseling, life coaching, and general wellness counseling are not covered, even if provided by a licensed therapist. If you need couples therapy for a diagnosed condition (such as depression affecting your relationship), your doctor may be able to order individual therapy, but not the couples sessions themselves.

Can I switch therapists without losing coverage?

Yes. As long as your new therapist is enrolled in Medicare and your doctor continues to order treatment, Medicare will cover sessions with a different provider. You do not need permission to change therapists. However, if you have a Medicare Advantage plan, your new therapist must be in your plan's network, or you may have to pay more out of pocket.

What if my therapist says I need therapy but my doctor will not order it?

Medicare requires a doctor's order for coverage. If your therapist believes you need treatment but your primary care doctor is reluctant to order it, you can ask for a referral to a psychiatrist, who can evaluate you and order therapy if appropriate. You can also ask your therapist to document their recommendation in writing and send it to your doctor, which sometimes prompts a conversation.

Does Medicare cover therapy for substance use or addiction?

Yes. Therapy for substance use disorder, alcohol use disorder, and addiction is covered under Part B when ordered by a doctor. This includes individual counseling and group therapy. Some specialized addiction treatment programs may be covered under Part A (inpatient) or Part B (outpatient), depending on the setting and your condition.

If I have both Original Medicare and a Medigap plan, how much do I pay per session?

You pay your Part B deductible once per year. After that, Original Medicare pays 80 percent of the approved amount, and your Medigap plan typically covers the remaining 20 percent, so you pay nothing per session. However, this depends on which Medigap plan you have—some plans have different rules. Check your Medigap policy or call your plan to confirm.
