Understanding Medicare: Minimum Hospital Stay Requirements

Medicare Part A covers inpatient hospital stays, but patients are responsible for paying a portion of the costs. The amount of coverage provided by Medicare depends on the length of the hospital stay. For the first 60 days, Medicare covers the full approved amount after the patient has paid the deductible. From day 61 to day 90, patients pay an additional daily rate of $419 in 2025. After 90 days, patients are responsible for paying a large portion of the costs out of pocket. Medicare provides an additional 60 days of coverage beyond the initial 90 days, known as lifetime reserve days, with a higher copayment cost of $838 per day.

Medicare Part A covers inpatient hospital stays

Medicare Part A, also known as hospital insurance, covers inpatient hospital stays. However, patients are responsible for paying a portion of the costs, including a deductible and daily copayments for stays exceeding 60 days. In 2025, the deductible for Medicare Part A will be $1,676 per benefit period, and the daily copayment for days 61 to 90 will be $419.

Medicare Part A typically covers inpatient surgeries, bloodwork, diagnostics, and hospital stays. It also covers care in critical access hospitals and skilled nursing facilities, as well as hospice care and some home health care. For example, if you require skilled nursing care and are homebound, Medicare Part A can cover up to 100 days of home healthcare if you spent at least three days as a hospital inpatient within 14 days of receiving home healthcare.

Inpatient hospital care under Medicare Part A usually requires that you are formally admitted to the hospital as an inpatient with a doctor's order, indicating that inpatient hospital care is necessary for treating your illness or injury. Additionally, the hospital must accept Medicare. It's important to note that the benefit period for Medicare Part A begins on the day of admission and ends after 60 consecutive days outside of the hospital. If you are admitted to the hospital again within this 60-day period, you won't need to pay another deductible. However, if you are admitted after the 60-day period, a new benefit period starts, and you will be responsible for paying another deductible.

While Medicare Part A provides coverage for inpatient hospital stays, it's important to understand that it doesn't cover all the costs. There are out-of-pocket expenses, including premiums, deductibles, coinsurance, and copayments. These costs can vary based on the length of your stay and the specific Medicare coverage you have. It's always a good idea to be prepared and understand the potential financial responsibilities associated with hospital stays, even with Medicare coverage.

Medicare Advantage plans, which include Medicare Parts A and B, may offer additional benefits, such as prescription drug plans and dental, hearing, and vision care. These plans can provide maximum out-of-pocket protections that original Medicare doesn't offer. However, they typically have smaller provider networks and may require prior authorizations for certain services. It's important to carefully consider the costs and benefits of different Medicare options to choose the coverage that best suits your needs.

Out-of-pocket costs

The out-of-pocket costs for inpatient hospital care depend on the duration of your stay. For the first 60 days, Medicare covers the full approved amount after you've paid the deductible. You pay nothing additional during this period.

After 60 days, you'll have to pay a coinsurance cost. For days 61 to 90, if you're still hospitalized, you'll pay an additional daily rate. In 2025, this rate is $419 per day. These days are still covered by Medicare Part A, but coinsurance costs apply.

After 90 days, if you require a longer stay, you can either use all or part of your lifetime reserve days or pay for all costs out-of-pocket. Medicare provides an additional 60 days of coverage beyond the initial 90 days, known as lifetime reserve days. These days can be used only once but don't have to be used all in one hospital visit. For example, if you have two extended hospital stays, each amounting to 120 days, you can use 30 lifetime reserve days for each period. However, the copayment cost for these reserve days is higher, at $838 per day.

Beyond 150 days, if you still require hospital care, you must pay for it out of pocket. It's important to note that Medicare Advantage plans may offer lower costs for hospital stays, but they have restrictions on where you can be treated. Additionally, Medicare Supplement Insurance (Medigap) policies can help cover out-of-pocket expenses, deductibles, and copays.

The exact amount of coverage that Medicare provides depends on how long a person stays in the hospital. While there is no yearly limit on what you pay out-of-pocket, some plans have an out-of-pocket maximum to prevent excessive financial burden. This is known as the maximum out-of-pocket (MOOP) limit, after which you won't be responsible for cost-sharing on covered services for the rest of the coverage period.

Lifetime reserve days

Medicare Part A covers inpatient hospital stays, but patients are responsible for paying a portion of the costs. These costs include a deductible and coinsurance. In 2025, the Medicare Part A deductible is $1,676 per benefit period. This means the deductible applies to the length of time you’re admitted to the hospital and continues for 60 consecutive days after you’ve been discharged from the hospital and have not received any inpatient care.

Medicare covers the full approved amount for the first 60 days after you’ve paid the deductible. For days 61 to 90, you’ll pay an additional daily rate. In 2025, this rate will be $419 each day. After 90 days, you'll need to pay much of the cost out of pocket.

However, Medicare provides an additional 60 days of coverage beyond the initial 90 days of covered inpatient care. These 60 days are known as lifetime reserve days and can be used only once. You will pay a higher copayment cost of $838 per day while using these lifetime reserve days.

Skilled nursing facility requirements

Medicare Part A covers inpatient hospital stays, but patients are responsible for paying a portion of the costs. These costs include a deductible and coinsurance. The deductible for 2025 is $1,676 per benefit period, and there is a daily coinsurance of $419 for days 61 to 90 of a hospital stay. After 90 days, you will need to pay a large portion of the costs out of pocket or use your lifetime reserve days.

Medicare Part A can also cover skilled nursing facility (SNF) care for a limited time if certain conditions are met. These conditions include having Part A with days left in your benefit period, having a qualifying inpatient hospital stay, entering the SNF within 30 days of leaving the hospital, and needing daily skilled care prescribed by a doctor. Medicare Advantage Plans may waive the 3-day minimum hospital stay requirement for SNF coverage. It is important to note that there may be out-of-pocket costs associated with SNF care, such as copayments during the first 20 days.

To ensure coverage for a skilled nursing facility stay, it is recommended to confirm with your doctor or hospital staff if Medicare will cover your SNF stay. Additionally, ask the SNF about bed availability if you need to be readmitted to the hospital during your stay. It is also worth considering Medicare Advantage Plans, which can offer maximum out-of-pocket protections that original Medicare does not provide. However, these plans may have smaller provider networks and require prior authorizations for many services.

Medicare Advantage plans

Enrollees in Medicare Advantage plans may face lower costs for hospital stays compared to Original Medicare. After meeting the deductible, Medicare Part A covers inpatient hospital stays for up to 60 days with no additional costs. From days 61 to 90, a daily coinsurance rate applies, and after day 90, individuals can use their lifetime reserve days or pay out-of-pocket.

It is important to note that Medicare Advantage plans can disenroll individuals for specific reasons, such as moving outside the plan's service area or losing Medicare eligibility. Before enrolling, individuals should review the rules and understand the potential impact on their existing coverage.
