Medigap Mental Health Coverage 2026: Does Your Medicare Supplement Cover Therapy and Psychiatric Care?

Mental health is medical health — and in 2026, that principle has never been more important for Medicare beneficiaries. With depression affecting nearly 20% of adults aged 65 and older, anxiety disorders on the rise among seniors, and the ongoing opioid and substance use crisis affecting older adults, understanding what your Medicare Supplement (Medigap) plan covers for mental health care is essential.

The good news: Medigap plans provide excellent mental health coverage because they supplement Original Medicare’s robust mental health benefits. But the specifics — which services are covered, how much you’ll pay per therapy session, and what happens during a psychiatric hospitalization — vary significantly between Plan G, Plan N, and other Medigap options.

This guide breaks down exactly what mental health services your Medigap plan covers in 2026, compares costs across plans, and helps you choose the right supplement for your mental health needs.

What Mental Health Services Does Original Medicare Cover?

Before understanding what Medigap covers, you need to know what Original Medicare (Parts A and B) pays for. Medicare’s mental health coverage has expanded significantly over the past decade, and 2026 brings full enforcement of mental health parity requirements.

Medicare Part A: Inpatient Mental Health Services

Medicare Part A covers inpatient mental health care in two settings:

Inpatient Psychiatric Hospital Stays

• Covered in freestanding psychiatric hospitals and psychiatric units of general hospitals
• Subject to the same benefit period rules as any other hospital stay
• 190-day lifetime limit on stays in freestanding psychiatric hospitals (no limit for psychiatric units of general hospitals)
• Part A deductible applies: $1,676 per benefit period in 2026
• Days 1-60: $0 coinsurance after deductible
• Days 61-90: $419/day coinsurance
• Days 91-150: $838/day (lifetime reserve days, limited to 60 days total)

Inpatient Substance Use Disorder Treatment

• Detoxification in a hospital setting
• Inpatient rehabilitation for substance use disorders
• Same cost structure as other hospital stays

Medicare Part B: Outpatient Mental Health Services

Medicare Part B covers a comprehensive range of outpatient mental health services at 80% of the Medicare-approved amount after the annual Part B deductible ($267 in 2026):

Individual and Group Psychotherapy

• Individual therapy sessions with licensed psychologists, psychiatrists, clinical social workers, and marriage and family therapists
• Group therapy sessions
• Cognitive Behavioral Therapy (CBT)
• Dialectical Behavior Therapy (DBT) when medically necessary

Psychiatric Services

• Psychiatric evaluations and diagnostic assessments
• Medication management appointments
• Electroconvulsive Therapy (ECT) for treatment-resistant depression
• Transcranial Magnetic Stimulation (TMS) for treatment-resistant depression

Substance Use Disorder Services

• Outpatient counseling and therapy
• Medication-Assisted Treatment (MAT) including buprenorphine, methadone, and naltrexone management
• Opioid Treatment Program (OTP) services
• Partial Hospitalization Programs (PHP) — structured, intensive day programs

Preventive Mental Health Services

• Annual depression screening (covered at 100% with no cost-sharing)
• Annual Wellness Visit includes mental health assessment components
• Alcohol misuse screening and behavioral counseling
• Tobacco cessation counseling

Telehealth Mental Health Services

• Audio-video telehealth therapy and psychiatry appointments
• Audio-only telehealth for mental health services (extended through 2026)
• Remote patient monitoring for mental health conditions

How Medigap Supplements Mental Health Coverage

This is where Medigap transforms your mental health cost picture. Original Medicare covers 80% of approved outpatient mental health services — but that leaves you paying 20% coinsurance with no annual out-of-pocket maximum. For someone in regular therapy, that coinsurance adds up fast.

What Each Medigap Plan Covers for Mental Health

Different Medigap plans handle mental health coinsurance differently:

Plan G — The Gold Standard for Mental Health

• Pays the full 20% coinsurance for all Part B mental health services
• Covers the $267 Part B deductible
• $0 coinsurance for therapy sessions, psychiatric visits, and substance use treatment
• Covers Part B excess charges (if a psychiatrist charges above Medicare’s approved amount)
• Best choice for beneficiaries who see mental health providers regularly

Plan N — Lower Premiums, Copays Apply

• Pays the 20% coinsurance for most services
• Requires a $20 copay per office visit — including therapy and psychiatric appointments
• Requires a $50 copay for ER visits (waived if admitted)
• Does NOT cover Part B excess charges
• May be cost-effective if you see a therapist infrequently

Plan G vs Plan N: Mental Health Cost Comparison

Weekly therapy (52 visits/year)

Plan G: $0 after deductible  |  Plan N: $1,040 in copays

Biweekly therapy (26 visits/year)

Plan G: $0 after deductible  |  Plan N: $520 in copays

Monthly psychiatry (12 visits/year)

Plan G: $0 after deductible  |  Plan N: $240 in copays

Annual cost difference

Plan N copays can exceed premium savings if you're in regular treatment

For a full comparison of these two popular plans, read our Medigap Plan G vs Plan N comparison guide.

Inpatient Mental Health: How Medigap Helps

For inpatient psychiatric care, Medigap coverage is especially valuable:

Expense	Without Medigap	With Plan G	With Plan N
Part A deductible ($1,676)	You pay full amount	$0	$0
Days 61-90 ($419/day)	You pay $419/day	$0	$0
Days 91-150 (lifetime reserve)	You pay $838/day	$0	$0
Blood (first 3 pints)	You pay	Covered	Covered

A 30-day inpatient psychiatric stay could cost over $1,676 out-of-pocket with Original Medicare alone. With Plan G or Plan N, that drops to $0.

Excess Charges: A Hidden Mental Health Cost

Some psychiatrists and therapists do not accept Medicare assignment — meaning they can charge up to 15% above Medicare’s approved amount. This is called a “Part B excess charge.”

Plan G covers excess charges. Plan N does not.

For mental health care, this matters more than you might think. Psychiatric practices have some of the highest rates of non-participating providers in Medicare. If your preferred psychiatrist charges 15% above the approved amount and you have Plan N, you pay that difference out-of-pocket.

The 190-Day Inpatient Psychiatric Hospital Limit

This is one of the most important — and least understood — limitations in Medicare. Here’s what you need to know:

What the limit covers: Medicare imposes a 190-day lifetime limit on inpatient stays in freestanding psychiatric hospitals. This is separate from the general hospital benefit, which has no lifetime day limit.

Key distinctions:

• Freestanding psychiatric hospitals: 190-day lifetime limit applies
• Psychiatric units of general hospitals: No 190-day limit — counted under regular Part A hospital benefits
• The limit is cumulative over your lifetime: Once you use 190 days, Medicare will not pay for additional freestanding psychiatric hospital days

What Medigap does: Medigap cannot extend the 190-day Medicare limit. However, Medigap covers all cost-sharing (deductibles and coinsurance) for the days that ARE covered, making inpatient psychiatric care financially accessible.

Planning tip: If you have a chronic mental health condition that may require repeated hospitalizations, work with your care team to utilize psychiatric units of general hospitals when possible, preserving your 190-day freestanding hospital benefit.

Substance Use Disorder Coverage and Medigap

The opioid crisis and rising substance use among older adults have made addiction treatment coverage critical. Medicare covers substance use disorder (SUD) treatment comprehensively, and Medigap strengthens this coverage.

Covered SUD Services

Inpatient Services (Part A):

• Medical detoxification in hospital settings
• Inpatient rehabilitation programs
• Stabilization and crisis intervention

Outpatient Services (Part B):

• Individual and group counseling
• Medication-Assisted Treatment (MAT) management visits
• Opioid Treatment Program (OTP) services including methadone dispensing
• Partial Hospitalization Programs (PHP) — 20+ hours per week of structured treatment
• Intensive Outpatient Programs (IOP)

What You Pay With vs Without Medigap

A typical 90-day outpatient substance use treatment program involving weekly individual counseling, weekly group therapy, and medication management might include:

• 12 individual therapy sessions ($150 each = $1,800 total)
• 12 group therapy sessions ($45 each = $540 total)
• 3 medication management visits ($200 each = $600 total)
• Total approved amount: ~$2,940

Without Medigap: You pay 20% coinsurance = $588 (plus the $267 deductible if not yet met)

With Plan G: You pay $0 after deductible

With Plan N: You pay $240 in copays (12 office visits × $20)

Mental Health Parity in 2026: What Changed

The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that mental health and substance use disorder benefits be covered at the same level as medical and surgical benefits. In 2026, several important developments strengthen this protection:

Stronger Enforcement: CMS has increased audits of plans that impose stricter utilization review or higher cost-sharing on mental health services compared to physical health services.

Medicare-Specific Parity: While Original Medicare has historically maintained parity, private Medicare Advantage plans face new compliance requirements. This is another reason many beneficiaries prefer Medigap with Original Medicare — mental health coverage follows Medicare’s straightforward 80/20 split without utilization management hurdles.

Network Adequacy Rules: New regulations require Medicare Advantage plans to maintain adequate mental health provider networks. However, Medigap beneficiaries already have unrestricted access to any Medicare-participating provider — no network restrictions at all.

988 Suicide & Crisis Lifeline Integration: Medicare covers services provided through connections made via the 988 Lifeline, and Medigap supplements this coverage. If you or someone you know is in crisis, call or text 988 — it’s free, confidential, and available 24/7.

Finding Mental Health Providers Who Accept Medicare

One advantage of Medigap is that you can see any provider who accepts Medicare assignment — nationwide, without referrals. But first, you need to find providers.

How to Find Medicare-Covered Mental Health Providers

1. Use the Medicare Care Compare tool at medicare.gov/care-compare — search for psychiatrists, psychologists, and therapists who accept Medicare
2. Contact your state’s Mental Health Association for referrals to Medicare-participating providers
3. Ask your primary care doctor for a referral — while Medigap doesn’t require referrals, your PCP likely knows Medicare-participating specialists
4. Check with community mental health centers — these typically accept Medicare and offer sliding-scale options
5. Call providers directly and ask: “Do you accept Medicare assignment?”

What If My Current Therapist Doesn’t Accept Medicare?

This is a common issue. If your therapist doesn’t accept Medicare:

• With Plan G: You can still see non-participating providers, and Plan G covers the Medicare-approved amount plus excess charges (up to 15% above the approved amount)
• With Plan N: You’d pay the full difference between the provider’s charge and Medicare’s approved amount, plus your $20 copay
• Option: Consider telehealth providers who accept Medicare — many are available statewide and offer greater flexibility

---

What Medigap Does NOT Cover for Mental Health

Medigap is comprehensive, but it has boundaries. Here’s what’s not covered:

Long-Term Care: Nursing home care for mental health conditions is not covered by Medicare or Medigap. If you need long-term residential mental health care, you’d need long-term care insurance or Medicaid.

Private Duty Nursing: Private psychiatric nurses in your home are not covered.

Non-Medical Counseling: Marriage counseling (unless diagnosed as a psychiatric condition), life coaching, pastoral counseling, and career counseling are not covered by Medicare or Medigap.

Experimental Treatments: Treatments without sufficient evidence of effectiveness, such as some forms of ketamine-assisted therapy (unless covered under specific FDA-approved protocols), may not be covered.

Services Outside the U.S.: Medigap Plans C, D, F, G, M, and N include foreign travel emergency coverage (up to plan limits after a $250 deductible), but this is limited to emergency care — not routine mental health services abroad.

Choosing the Right Medigap Plan for Mental Health Needs

If mental health care is a priority — or you anticipate needing regular therapy — here’s how to choose:

Choose Plan G If:

• You see a therapist weekly or biweekly
• You take psychiatric medications requiring regular management
• You want $0 cost per session after the deductible
• You want protection against excess charges from non-participating psychiatrists
• You have a chronic mental health condition (depression, anxiety, bipolar, PTSD)

Choose Plan N If:

• You see a therapist monthly or less frequently
• Your therapist accepts Medicare assignment (no excess charges)
• Lower monthly premiums are more important than per-visit savings
• You’re generally healthy and want coverage “just in case”

Time Your Enrollment Wisely

The best time to buy a Medigap policy is during your 6-month Medigap Open Enrollment Period, which starts the month you’re both 65+ and enrolled in Medicare Part B. During this window:

• No medical underwriting required
• No pre-existing condition waiting periods (in most cases)
• No higher premiums based on mental health history

Learn more in our Best Time to Buy a Medigap Policy guide.

If you wait and try to buy Medigap later, insurers can ask about your mental health history and may charge higher premiums — or deny coverage — based on conditions like depression, anxiety, or past psychiatric hospitalizations.

Frequently Asked Questions

Does Medigap cover outpatient therapy and counseling sessions?

Yes. Medigap covers the 20% coinsurance that Original Medicare does not pay for outpatient mental health services. With Plan G, your cost is $0 per therapy session after the annual $267 Part B deductible. With Plan N, you pay a $20 copay per office visit for therapy sessions. Covered services include individual psychotherapy, group therapy, cognitive behavioral therapy, and counseling with licensed clinical social workers, psychologists, and psychiatrists.

Does Medicare Supplement cover inpatient psychiatric hospital stays?

Medigap helps cover inpatient psychiatric hospital costs under Medicare Part A, including the deductible and daily coinsurance. However, Medicare imposes a 190-day lifetime limit on inpatient psychiatric hospital care in freestanding psychiatric facilities. Medigap Plan G covers the Part A deductible ($1,676 in 2026) and all daily coinsurance for days 61-150 of a benefit period. Psychiatric units of general hospitals are not subject to the 190-day limit.

How much does therapy cost with Medigap Plan G vs Plan N in 2026?

With Plan G, therapy sessions cost $0 after you meet the $267 annual Part B deductible — there is no per-session cost-sharing. With Plan N, you pay a $20 copay per office therapy visit in addition to the Part B deductible. If you see a therapist weekly for a year (52 sessions), Plan N copays total $1,040, while Plan G costs $0 per session after the deductible. However, Plan N typically has lower monthly premiums, so the best choice depends on your therapy frequency and premium difference.

Does Medigap cover substance use disorder and addiction treatment?

Yes. Medigap supplements Medicare’s coverage of substance use disorder treatment, including inpatient detoxification, outpatient counseling, medication-assisted treatment (MAT), opioid treatment program services, and partial hospitalization programs. Plan G covers the full 20% coinsurance for all these services with no copays. Plan N covers most costs but requires a $20 copay for office-based visits. MAT medications like buprenorphine are covered under Medicare Part D, not Medigap.

Are there coverage limits for mental health services under Medigap?

Medigap itself has no annual or lifetime limits on mental health coverage — it pays whatever Medicare approves for covered services. However, Medicare Part A has a 190-day lifetime limit on inpatient psychiatric hospital stays in freestanding psychiatric facilities. Outpatient mental health services under Part B have no visit limits as long as the services are medically necessary and provided by a Medicare-participating professional. Mental health parity laws ensure these benefits cannot be more restricted than physical health benefits.

Does Medigap cover telehealth therapy and virtual psychiatric appointments?

Yes. Medigap covers telehealth mental health services the same way it covers in-person visits. Medicare Part B pays 80% of the approved amount for virtual therapy sessions, psychiatric evaluations via telehealth, and online counseling, and your Medigap plan covers the remaining coinsurance. Audio-only telehealth for mental health services remains covered through 2026. Learn more in our Medicare Telehealth Coverage guide.

Can I see any therapist or psychiatrist with my Medigap plan?

Yes, as long as the provider accepts Medicare assignment. Unlike Medicare Advantage plans that restrict you to in-network providers, Medigap with Original Medicare lets you see any Medicare-participating mental health provider nationwide without referrals. This includes psychiatrists (MD/DO), psychologists (PhD/PsyD), licensed clinical social workers (LCSW), licensed professional counselors (LPC), and licensed marriage and family therapists (LMFT). Plan G also provides partial coverage if you see a provider who doesn’t accept assignment, covering up to 15% in excess charges.
