Yes, Medicare covers inpatient psychiatric care under Part A. You can receive treatment in either a general hospital’s psychiatric unit or a freestanding psychiatric hospital, though the rules differ depending on which type of facility you use. The most important distinction is a 190-day lifetime limit that applies only to freestanding psychiatric hospitals.
What Part A Covers
Medicare Part A pays for inpatient psychiatric services the same way it covers other hospital stays. This includes a semi-private room, meals, nursing care, therapy sessions, lab tests, and medications administered during your stay. The coverage applies whether you’re admitted for a crisis like acute psychosis, severe depression with suicidal ideation, or any other mental health condition that requires round-the-clock care.
Doctor services during your hospitalization are handled separately. Psychiatrists, psychologists, and other providers who treat you while you’re inpatient bill through Part B. After you meet the Part B deductible, you typically pay 20% of the Medicare-approved amount for those professional fees.
General Hospital vs. Psychiatric Hospital
Where you receive care makes a significant difference in how Medicare calculates your benefits. If you’re treated in a psychiatric unit within a general hospital, there is no special day limit. Your stay is counted like any other hospital admission, with the standard benefit period rules applying.
If you’re treated in a freestanding psychiatric hospital (a facility that exclusively treats mental health conditions), Part A caps coverage at 190 days over your entire lifetime. Once you’ve used those 190 days, Medicare will not pay for additional time in a freestanding psychiatric facility, regardless of medical necessity. Days spent in a general hospital’s psychiatric unit do not count toward this 190-day cap. This distinction is worth keeping in mind if you anticipate needing multiple hospitalizations over the years.
What You’ll Pay Out of Pocket
The cost structure for a psychiatric admission mirrors any other Part A hospital stay. For 2025, you pay a $1,676 deductible at the start of each benefit period. A new benefit period begins after you’ve been out of the hospital (or skilled nursing facility) for 60 consecutive days.
After the deductible, here’s how the daily costs break down:
- Days 1 through 60: $0 per day
- Days 61 through 90: $434 per day in coinsurance
- Days 91 through 150: $868 per day, drawing from your 60 lifetime reserve days
- After day 150: You pay all costs
Lifetime reserve days are a one-time pool of 60 extra days that Medicare provides across your entire enrollment. Once you use them, they don’t renew. If you have a Medigap (Medicare Supplement) plan, it may cover some or all of these coinsurance costs depending on your policy.
Medicare Advantage Plans
If you’re enrolled in a Medicare Advantage plan (Part C), your plan is required to cover everything Original Medicare covers, including inpatient psychiatric care. However, the details often differ. Medicare Advantage plans can require prior authorization before admitting you to a psychiatric facility, and they typically limit coverage to in-network hospitals. Out-of-network stays may cost significantly more or may not be covered at all except in emergencies.
Your copay and coinsurance amounts will also follow your plan’s specific schedule rather than the Original Medicare rates listed above. Check your plan’s Evidence of Coverage document or call the number on your member card to confirm what your costs would be for an inpatient psychiatric stay.
Partial Hospitalization as a Step Down
Medicare also covers partial hospitalization programs, which serve as an intermediate level of care between full inpatient treatment and regular outpatient visits. These programs run during the day (less than 24 hours) and include intensive services like psychotherapy, medication management, occupational therapy, and nursing support. You return home each evening.
To qualify, you need to meet a specific set of conditions. Your mental health condition must be severe enough that a standard outpatient program wouldn’t be sufficient, but you don’t require 24-hour supervision. You also need a stable living situation and can’t be an immediate danger to yourself or others. A psychiatrist or physician must certify that you need this level of care. Partial hospitalization is billed under Part B, so you’ll pay the Part B deductible and then 20% of the Medicare-approved amount for each day of services.
These programs are available through hospitals and community mental health centers, and they’re often used as a transition after discharge from a full inpatient stay to help prevent readmission.
Planning Around the 190-Day Limit
If you or a family member has a chronic psychiatric condition that may require repeated hospitalizations, the 190-day lifetime limit on freestanding psychiatric hospitals is the single most important rule to understand. Every day spent in a freestanding facility chips away at that cap permanently. One strategy is to seek treatment in a psychiatric unit within a general hospital whenever possible, since those days carry no special limit. Not every area has this option, and freestanding psychiatric hospitals sometimes offer more specialized programming, so the choice involves trade-offs. But knowing the distinction gives you leverage to ask the right questions before an admission happens.
