Learn About Nursing Home Care Under Medicare

What Medicare Covers for Nursing Home Care

Medicare is a federal health insurance program that covers certain nursing home costs, but it does not cover all types of long-term care or custodial services. Understanding what Medicare pays for—and what it does not—is important when planning for potential nursing home needs.

Medicare Part A covers skilled nursing facility (SNF) care when specific conditions are met. Skilled nursing care involves medical services provided by licensed nurses under a doctor's supervision. This includes wound care, medication management, physical therapy, and other treatments that require nursing expertise. According to the Centers for Medicare & Medicaid Services (CMS), skilled nursing facilities differ from regular nursing homes because they provide medically complex care rather than just assistance with daily activities.

For a nursing home stay to be covered by Medicare Part A, the person must be admitted to a Medicare-certified skilled nursing facility within 30 days of being discharged from a hospital stay lasting at least three consecutive days (not counting the discharge day). This requirement exists because Medicare Part A is designed to cover care that continues recovery from a recent hospitalization—not permanent or indefinite nursing home residence.

The actual services covered include room and board in a semi-private room, meals, nursing services, therapy services (such as physical, occupational, or speech therapy), medications administered in the facility, medical equipment and supplies (like oxygen or wheelchairs), and social services. However, Medicare does not cover personal care services such as help with bathing, dressing, eating, or toileting when these are the only services a person needs. These custodial care services are often the largest portion of nursing home expenses and remain the resident's responsibility.

As of 2024, Medicare Part A covers up to 100 days per stay in a skilled nursing facility. The coverage works on a per-benefit-period basis. Days 1-20 are fully covered by Medicare, with the facility and Medicare handling all costs. From days 21-100, the beneficiary pays a daily coinsurance amount (in 2024, this is $200 per day), while Medicare covers the remainder. After day 100 in a single benefit period, all costs become the resident's responsibility.

Practical Takeaway: Before assuming Medicare will pay for a nursing home stay, verify that the facility is Medicare-certified, that the stay follows a qualifying hospital admission, and that the care needed is skilled nursing care rather than custodial care. Contact the nursing home's admissions office to confirm Medicare acceptance and understand what costs will and will not be covered.

The Three-Day Hospital Stay Requirement

One of the most misunderstood aspects of Medicare nursing home coverage is the three-day hospital stay requirement. Many people believe Medicare will pay for nursing home care after a brief outpatient visit or emergency room visit, but the rule is specific: there must be a qualifying hospital stay of at least three consecutive midnights in a hospital.

The counting method matters. The three days include the day of admission and the day of discharge, but the day of discharge is not counted as an overnight stay. This means a person admitted on a Monday and discharged on Thursday would have three qualifying midnights: Monday night, Tuesday night, and Wednesday night. An admission on Monday with discharge on Wednesday would only count as two qualifying midnights and would not meet the requirement.

This requirement exists because Medicare Part A is structured to cover post-acute care—care needed to recover from the medical event that caused hospitalization. The logic is that if someone needed hospitalization, they are likely to need additional skilled nursing care to continue their recovery. However, this rule creates gaps in coverage. A person who visits an emergency room and is sent home, or who receives outpatient surgery and is discharged the same day, does not meet the requirement even if they later need nursing home care for the same condition.

According to Medicare data, approximately 10-15% of people who are admitted to nursing homes do not meet the three-day qualifying hospital stay requirement, and therefore cannot use Medicare Part A to pay for their care. These individuals must pay privately or rely on other insurance programs like Medicaid.

The three-day requirement clock begins when the patient is formally admitted to the hospital as an inpatient. Observation stays—a category where patients are monitored but not formally admitted—do not count toward the three-day requirement, even if the patient stays for several days. Some hospitals use observation status rather than inpatient admission for certain patients, which can inadvertently disqualify them from Medicare nursing home coverage. Patients and families should ask hospital staff whether the admission status is "inpatient" (which counts) or "under observation" (which does not).

Practical Takeaway: Before discharge from a hospital, confirm with hospital staff that the admission was inpatient status and that at least three midnights will be counted. Request this information in writing to have documentation for future reference. If there is any question about whether the stay qualifies, ask to speak with the hospital's patient advocate or compliance office.

Coverage Duration and Cost-Sharing Details

The duration of Medicare's nursing home coverage depends on the individual's specific situation and the length of time they need skilled nursing care. While Medicare covers up to 100 days per benefit period, most skilled nursing stays are much shorter. According to the Centers for Medicare & Medicaid Services, the average length of a Medicare-covered nursing home stay is approximately 28 days, though this varies widely based on the type of care needed and how quickly the person recovers.

Understanding the cost structure is essential for financial planning. During days 1-20 of a Medicare-covered stay, Medicare covers all covered charges. The facility cannot bill the patient for these services; Medicare pays directly to the facility. The patient typically only pays for items or services that Medicare does not cover, such as television, telephone, or private room upgrades.

From days 21-100, the patient is responsible for a daily coinsurance amount. In 2024, this amount is $200 per day. Medicare covers the rest of the facility's charges. If the facility's daily rate is $300 and Medicare's payment is $100, the patient owes the coinsurance ($200) but not the difference between the facility rate and Medicare payment. However, if the facility is a non-participating (non-accepting) Medicare facility, patients may face higher out-of-pocket costs.

The benefit period is a key concept that affects coverage. A benefit period begins when a person enters a hospital or skilled nursing facility and ends after they have not received hospital or skilled nursing facility care for 60 consecutive days. Once a benefit period ends, a new benefit period can begin, and the person is eligible for another 100 days of skilled nursing coverage. There is no limit to how many benefit periods a Medicare beneficiary can have in their lifetime, so theoretically, a person could receive multiple 100-day covered stays if they qualify for each one.

It is important to note that the 100-day limit applies to each benefit period, not per year or per lifetime in total. A person who receives 100 days of nursing home care in January could receive another 100 days in March of the same year if they meet the qualifying criteria (a new hospital stay) for the second stay. However, in most cases, beneficiaries do not have consecutive nursing home stays because the three-day hospital stay requirement must be met for each stay.

Practical Takeaway: When calculating potential nursing home costs, budget for the daily coinsurance from day 21 onward. For a 40-day stay in 2024, this would mean 20 days at $200/day = $4,000 out-of-pocket. Many people purchase supplemental insurance ("Medigap") or long-term care insurance specifically to cover these coinsurance costs.

Types of Facilities and Medicare Certification

Not all nursing homes are the same, and Medicare only pays for care in facilities that meet Medicare certification requirements. Understanding the differences between facility types helps explain why some nursing homes accept Medicare and others do not.

A skilled nursing facility (SNF) is a licensed facility that specializes in providing skilled nursing care and related rehabilitation services. SNFs have licensed nurses available around the clock, doctors on call, and equipment for handling medically complex patients. To be certified for Medicare, an SNF must meet federal standards for staffing, training, safety, infection control, and quality of care. These standards are enforced through regular inspections by state surveyors.

A nursing home is a broader term that can include facilities ranging from skilled nursing facilities to board-and-care homes. Some nursing homes have
