Key Takeaways
-
Medicare covers a wide range of mental health services, but not all services or providers are automatically approved. Knowing what is eligible for reimbursement can help you avoid surprise bills.
-
Coverage depends on the type of provider, service setting, and the medical necessity of the treatment. You must also meet specific eligibility criteria for ongoing care.
What Medicare Does Cover for Mental Health in 2025
Medicare provides mental health coverage through multiple parts, with specific limits and cost-sharing rules. Understanding each part’s role can help you plan your care more effectively.
Inpatient Psychiatric Hospital Care (Part A)
Medicare Part A covers mental health services provided in a psychiatric hospital or a general hospital. However, there are important rules:
-
You are covered for up to 190 days in a psychiatric hospital over your lifetime. This is a hard limit and does not reset.
-
General hospitals do not count toward the 190-day limit, but the same Part A deductible and coinsurance rules apply.
-
Coverage includes semi-private rooms, meals, nursing care, and medications related to your condition.
Outpatient Mental Health Services (Part B)
Medicare Part B covers outpatient mental health services, including:
-
Diagnostic evaluations
-
Individual and group therapy
-
Medication management
-
Psychiatric nurse practitioner visits
-
Family counseling (if it helps your treatment)
-
Partial hospitalization programs (PHPs)
Starting January 1, 2024, Medicare also began covering licensed marriage and family therapists (LMFTs) and mental health counselors (MHCs).
You are responsible for:
-
The annual Part B deductible, which is $257 in 2025
-
20% of the Medicare-approved amount for most services, unless you have additional insurance
Prescription Drug Coverage (Part D)
Mental health medications are covered under Medicare Part D. This includes antidepressants, antipsychotics, mood stabilizers, and anti-anxiety drugs.
In 2025, out-of-pocket spending on prescriptions is capped at $2,000 per year. This includes all your mental health medications, but only if you stay within your plan’s drug list (formulary).
Services That Often Get Denied or Limited
While Medicare covers many mental health treatments, not everything is automatically approved. Here are some areas where coverage may be denied or limited.
1. Services from Non-Approved Providers
Medicare only reimburses services from professionals who are Medicare-approved providers. Even if someone is licensed in your state, they must also be enrolled in Medicare to receive payment. If you see an out-of-network therapist or counselor not enrolled in Medicare, you may be responsible for the full cost.
2. Excessive Therapy Sessions Without Medical Necessity
Medicare reviews therapy frequency and duration to determine if it’s medically necessary. Long-term therapy without improvement or without periodic reevaluation can lead to coverage denials. You may need your provider to document progress and necessity to continue coverage.
3. Telehealth Visits Without Proper Documentation
Medicare permanently allows mental health services through telehealth, including video and audio-only visits. However, you must have at least one in-person visit every 12 months (unless you qualify for an exception). Skipping this requirement can result in claims being denied.
4. Services in Certain Care Settings
If you’re receiving care in settings such as assisted living or adult day care, Medicare generally does not cover mental health services provided in those locations unless they’re part of a covered home health or outpatient service. You may also be denied coverage if the provider bills incorrectly for these visits.
5. Unlisted or Off-Label Medications
Medicare Part D plans have formularies that specify which medications they cover. If a medication is not on the list, or if it is being used for an unapproved purpose, coverage may be denied. You can request an exception, but it requires prior authorization.
How to Confirm What Medicare Will Pay For
Before booking an appointment or starting treatment, take these steps to confirm that Medicare will cover the service.
Check Provider Status
-
Make sure your provider accepts Medicare assignment.
-
Verify that therapists and counselors are enrolled and eligible to bill Medicare.
Ask About Coding and Documentation
-
Ensure your provider knows how to code the services appropriately.
-
They should be able to show how the treatment meets Medicare’s definition of medical necessity.
Review Your Medicare Summary Notice (MSN)
After receiving care, review your MSN for any denials or discrepancies. This notice details what was billed, what Medicare paid, and what you may owe.
Use Medicare’s Online Tools
-
You can search for Medicare-approved providers at Medicare.gov.
-
Use your MyMedicare account to track covered services and costs.
When Prior Authorization Is Needed
Most mental health services under Original Medicare do not require prior authorization. However, some Medicare Advantage plans do have prior approval requirements for:
-
Intensive outpatient programs (IOP)
-
Partial hospitalization programs (PHP)
-
Certain high-cost medications
If you’re in a Medicare Advantage plan, always check the plan’s specific requirements to avoid unexpected denials.
What to Do If Coverage Is Denied
If Medicare or your Medicare Advantage plan denies a claim, you have the right to appeal. Follow these steps:
Step 1: Review the Denial Letter
Understand why the service was denied. The notice will include:
-
The service or item denied
-
The reason for denial
-
Information about how to appeal
Step 2: File an Appeal
You must appeal within 120 days of the denial notice. The appeal should include:
-
A written statement explaining why you believe the service should be covered
-
Supporting documentation from your provider
Step 3: Request Expedited Review (if applicable)
If the denial involves urgent mental health care, you may qualify for a fast-track appeal, which results in a decision within 72 hours.
Step 4: Consider Second-Level Appeals
If your first appeal is denied, you can continue the process through up to five levels of appeals, including review by an Administrative Law Judge.

What Medicare Advantage Covers

-
Additional therapy sessions

Broader provider networks (or narrower, depending on the plan)
-
Wellness programs for mental health
-
Telehealth access without in-person requirements
However, Medicare Advantage plans can impose:

Network restrictions

Referral requirements

Prior authorizations
You should carefully review your plan’s Evidence of Coverage (EOC) to understand what’s allowed and what’s limited.
Hidden Costs You Might Miss
Even when Medicare covers a mental health service, you could still face out-of-pocket costs, including:
-
Copayments if you’re in a Medicare Advantage plan
-
Coinsurance under Part B (generally 20%)
-
Deductibles for both Part B and Part D
-
Out-of-network costs if you accidentally see a provider who doesn’t take Medicare
-
Costs for non-covered services, such as coaching, life skills training, or alternative therapies
Telehealth in 2025: Expanded but Conditional
Telehealth for mental health continues to be a covered service under Medicare in 2025. However, to maintain eligibility:
-
You must complete an in-person visit every 12 months
-
Services must be provided by a qualified Medicare provider
-
Audio-only visits are allowed but must meet specific documentation requirements
The in-person visit requirement may be waived if:
-
You have a documented hardship or
-
You live in an area with limited provider access
Making the Most of Your Mental Health Coverage
To ensure you get the help you need while avoiding surprise bills:
-
Always check your provider’s Medicare status
-
Get services pre-approved if required by your plan
-
Understand what is considered medically necessary
-
Monitor your drug formulary and request exceptions as needed
-
Keep records of all visits, treatments, and communications
Be Informed Before You Schedule That Visit
Knowing what Medicare actually covers for mental health services in 2025 can make the difference between receiving care and receiving a bill you didn’t expect. Many enrollees assume that if a service helps their mental health, Medicare will pay for it. That’s not always true. Understand the limitations, know the coverage rules, and ask questions up front.
