Yes, Medicare covers inpatient psychiatric care. Part A (hospital insurance) pays for mental health services when you’re admitted as an inpatient, whether that’s in a general hospital or a freestanding psychiatric facility. The coverage rules, cost-sharing amounts, and day limits differ depending on where you receive care, so understanding these details can save you from unexpected bills.
What Medicare Part A Covers
Part A handles the core hospital costs of an inpatient psychiatric stay: your room, meals, nursing care, group and individual therapy, and medications administered during your hospitalization. These are bundled into the hospital’s charges and covered under Part A’s standard inpatient benefit structure.
Part B covers a separate piece: the professional services you receive from doctors, psychiatrists, and other providers while you’re in the hospital. You’ll pay 20% of the Medicare-approved amount for those physician services. This means two different parts of Medicare are working at the same time during a single stay, each with its own cost-sharing rules.
The 190-Day Lifetime Limit
The most important distinction in Medicare psychiatric coverage is where you’re treated. If you’re admitted to a freestanding psychiatric hospital (a facility that exclusively treats mental health conditions), Part A will only pay for up to 190 days total over your entire lifetime. Once those 190 days are used, they don’t reset. This is a hard cap that applies no matter how many years pass between admissions.
This limit does not apply if you receive psychiatric care in a general hospital or in a Medicare-certified psychiatric unit within an acute care or critical access hospital. In those settings, your inpatient days are counted under the same benefit period rules as any other hospitalization, with no lifetime psychiatric cap. For people who may need longer or repeated inpatient stays, this difference in facility type has major financial implications.
What You’ll Pay Out of Pocket
Inpatient psychiatric stays follow the same cost-sharing structure as other hospital admissions under Part A. For 2025, the numbers break down like this:
- Days 1 through 60: You pay nothing after meeting the Part A deductible of $1,676 per benefit period.
- Days 61 through 90: You pay $419 per day in coinsurance.
- Days 91 and beyond: You pay $838 per day, drawing from a pool of 60 lifetime reserve days. Once those are gone, they don’t come back.
For 2026, the deductible rises to $1,736, with coinsurance increasing to $434 per day for days 61 through 90 and $868 per day for lifetime reserve days. After you’ve exhausted all your lifetime reserve days, you’re responsible for the full cost of each additional day.
A benefit period starts the day you’re admitted and ends after you’ve been out of a hospital or skilled nursing facility for 60 consecutive days. If you’re readmitted after that 60-day window, a new benefit period begins and you’ll owe the deductible again, but your 60-day and 90-day counters reset. Your lifetime reserve days, however, never reset.
How Medicare Decides Your Stay Is Covered
Medicare doesn’t automatically pay for every day you spend in a psychiatric facility. A physician must certify at the time of admission (or shortly after) that your hospitalization is medically necessary, meaning the treatment is expected to improve your condition or is needed for a diagnostic evaluation. A second certification is required by the 12th day of your stay, and after that, recertification must happen at least every 30 days for as long as you remain an inpatient.
This means your care team is regularly documenting that you still need hospital-level treatment. If Medicare determines at any point that your condition could be managed in a less intensive setting, coverage for the inpatient stay can end. This is one reason some psychiatric hospitalizations are shorter than patients or families expect. The hospital’s utilization review committee plays a role in setting the recertification schedule, and in some cases reviews happen on a daily basis.
Medicare Advantage Plans
If you’re enrolled in a Medicare Advantage plan (Part C) rather than Original Medicare, your plan is required by law to cover at least the same inpatient psychiatric benefits that Original Medicare provides. In practice, though, the experience can look different. Advantage plans typically use provider networks, so you may need to use specific hospitals or psychiatric facilities to get in-network rates. Many plans also require prior authorization before an inpatient psychiatric admission, which means the plan must approve the stay before (or shortly after) it begins.
Cost-sharing under Advantage plans varies by plan. Some charge a flat copay per day rather than the deductible-plus-coinsurance structure of Original Medicare, and some have annual out-of-pocket maximums that cap your total spending. Check your plan’s Evidence of Coverage document for the specifics, because two Advantage plans in the same city can have very different cost structures for inpatient mental health care.
What Isn’t Covered
Even during a covered inpatient stay, Medicare won’t pay for personal comfort items like televisions, radios, or barber and beauty services. These are considered unrelated to your treatment. The hospital can charge you for these items, but it cannot require you to purchase them as a condition of your admission or continued stay.
There is one exception worth noting: in freestanding psychiatric hospitals (and skilled nursing facilities), Medicare may cover basic grooming services like shaves, haircuts, and shampoos if you can’t perform them yourself. These are considered part of routine resident care when the facility includes them in its standard charges and provides them without a separate patient fee. The distinction comes down to whether the service is a personal luxury or a basic need you can’t meet on your own during a longer stay.
Private rooms are another area where coverage gets specific. Medicare generally pays for semi-private accommodations. A private room is only covered when it’s medically necessary, for instance if isolation is required for infection control or if your clinical situation demands it. Otherwise, the cost difference falls on you.
