How Medicare Coverage for Nursing Home Care Works

Medicare is a federal health insurance program that covers people age 65 and older, as well as some younger people with disabilities or end-stage renal disease. When it comes to nursing home care, Medicare has specific rules about what it covers and for how long. Understanding these rules helps you plan for potential long-term care needs and know what out-of-pocket costs might come your way.

Medicare divides nursing home coverage into two main scenarios: skilled nursing facility (SNF) care and custodial care. Skilled nursing facility care includes medical services like physical therapy, wound care, medication management, and nursing services provided by licensed nurses. This is the type of care Medicare may cover. Custodial care, by contrast, focuses on help with daily activities like bathing, dressing, eating, and using the bathroom. Medicare typically does not cover custodial care costs.

The distinction matters because many people enter nursing homes primarily needing help with daily activities rather than skilled medical care. According to data from the U.S. Department of Health and Human Services, about 80% of nursing home residents rely on Medicaid rather than Medicare as their primary payer for long-term care. This statistic shows that most nursing home residents do not have their stay covered by Medicare.

Medicare coverage for nursing home care requires that you first spend at least three consecutive days in a hospital. This is called the three-day qualifying hospital stay. After leaving the hospital, you must enter a Medicare-certified nursing facility within 30 days and be admitted for skilled care that relates to your hospital stay. If you skip the hospital stay or wait longer than 30 days, Medicare coverage for that nursing home stay will not apply.

Practical takeaway: Learn the difference between skilled nursing care and custodial care before discussing nursing home placement with doctors or family members. This knowledge helps you understand which costs Medicare might cover in your specific situation.

The Three-Day Hospital Stay Requirement

One of the most important rules for Medicare nursing home coverage involves the three-day hospital stay. This requirement has been in place for decades and remains a key factor in determining whether Medicare will pay for skilled nursing facility care. Many people are surprised to learn that observation stays do not count toward this requirement—only inpatient hospital admissions count.

An inpatient hospital admission means you have been formally admitted to the hospital under an inpatient status. When you arrive at a hospital emergency room or are transferred from another facility, hospital staff determine whether you should be admitted as an inpatient or held for observation. The difference is significant. According to Medicare data, observation stays have increased substantially in recent years. In 2022, Medicare covered roughly 50 million inpatient hospital days but also paid for millions of observation stays that do not count toward the three-day requirement.

The three consecutive days must occur before you leave the hospital. For example, if you are admitted to the hospital on Monday and leave on Thursday, you have stayed three nights (Monday night, Tuesday night, and Wednesday night), which satisfies the requirement. However, the day you are discharged does not count as a full day for this purpose. Once you have completed three consecutive days as an inpatient, the requirement is met even if your hospital stay continues beyond three days.

The timing between hospital discharge and nursing home admission is equally important. You must enter the nursing facility within 30 days of leaving the hospital. If you go home for a week and then decide you need nursing home care, the 30-day window may have passed, and Medicare will not cover that stay. Some exceptions exist for people who are readmitted to the hospital within 30 days of the original discharge—in certain cases, the clock restarts. However, these exceptions are specific and do not apply to all situations.

The nursing home you enter must also be Medicare-certified. Not all nursing homes accept Medicare coverage. You can verify whether a specific facility is Medicare-certified by searching the Medicare Care Compare tool on the official Medicare website. This tool provides information about which facilities accept Medicare and their quality ratings.

Practical takeaway: Before agreeing to an observation stay instead of inpatient admission, ask the hospital care team whether inpatient status is an option. This single decision can determine whether Medicare covers your subsequent nursing home care.

What Medicare Covers During Your Nursing Home Stay

Medicare Part A covers the costs of skilled nursing facility care for people who meet the requirements discussed earlier. Understanding exactly what is covered helps you budget for potential out-of-pocket expenses. Medicare covers the full cost of the first 20 days of skilled nursing facility care in a benefit period. For days 21 through 100, Medicare covers all costs except a daily coinsurance amount. In 2024, the daily coinsurance for days 21-100 is $208 per day. After 100 days in a benefit period, Medicare coverage ends and you become responsible for all costs.

A benefit period is a Medicare term that begins the day you are admitted to the hospital and continues until you have been out of a hospital or skilled nursing facility for 60 consecutive days. Once you have been out for 60 days, a new benefit period starts if you are readmitted. This means you can potentially have multiple nursing home stays covered by Medicare in a single year if they are separated by at least 60 days outside the facility.

What does Medicare actually pay for during your stay? Medicare covers room and board (your semi-private room and meals), skilled nursing care, physical therapy, occupational therapy, speech therapy, medical equipment like wheelchairs or walkers, prescription medications given during your stay, and laboratory and diagnostic services. The facility's basic services—including laundry, housekeeping, and maintenance—are also covered as part of the daily rate.

What Medicare does not cover reveals what you might owe out of pocket. Medicare does not cover private room upgrades unless medically necessary, telephone or television service, personal grooming items, dentures or dental work, eyeglasses or hearing aids, and custodial or personal care services. If you receive physical therapy or occupational therapy beyond what Medicare covers, you pay for the additional sessions. Some facilities provide these services, but you would receive an explanation of benefits showing what Medicare paid and what you owe.

Many people assume that once they enter a nursing home with Medicare coverage, the facility will provide all necessary care at no additional charge. This is not always accurate. Some skilled nursing facilities charge supplemental fees for services beyond what Medicare covers or for services that exceed Medicare's payment limits. Before admitting yourself or a family member, ask the facility to explain its billing practices and what services may result in additional charges.

Practical takeaway: Request a clear written list from the nursing home showing what Medicare covers, what you might owe during days 21-100, and what services the facility charges separately. Compare this information across multiple facilities before deciding where to receive care.

Daily Costs and Coinsurance Amounts

Understanding the specific dollar amounts you might owe helps with financial planning. As mentioned, Medicare covers the full cost of days 1-20, but you pay nothing during this period. For days 21-100, you pay a coinsurance amount that increases each year. The coinsurance reflects Medicare's contribution to the facility's charges. In 2024, the daily coinsurance is $208 per day. If your nursing home stay lasts 80 days, you would pay coinsurance for 60 days (days 21-80), which equals approximately $12,480 before any additional charges.

These coinsurance amounts apply only to the daily room and board charges that Medicare covers. If the nursing home charges more than Medicare's approved amount, you may owe the difference. This is called "balance billing," and Medicare regulations limit how much facilities can balance bill. However, some facilities do charge additional amounts, so asking about this upfront is important.

Many people prepare for potential nursing home care by purchasing long-term care insurance, which may cover some or all of the coinsurance amounts and services that Medicare does not cover. Long-term care insurance policies vary widely in their coverage amounts, waiting periods, and daily benefit limits. According to the American Association for Long-Term Care Insurance, the average cost of a semi-private room in a nursing home in 2023 was approximately $108,405 per year, or about $296 per day. Medicare's daily coinsurance of $208 covers much of this, but the gap is significant.

Other people use savings, investments, or family resources to cover coinsurance amounts. Still others may explore Medicaid, which covers nursing home care after Medicare coverage ends and after spending down assets to meet
