How Medicare Covers Skilled Nursing Facility Care

Medicare Part A provides coverage for skilled nursing facility (SNF) care under specific circumstances. This is distinct from long-term custodial care or assisted living. Understanding what Medicare will and won't cover requires knowing the difference between skilled care and other types of nursing home services.

Skilled nursing facilities provide medical care that requires a nurse or therapist to deliver it safely and effectively. This includes wound care, intravenous medications, physical therapy after surgery, management of complex medical conditions, and monitoring for patients who need frequent medical assessments. A nursing home that primarily provides help with daily activities like bathing, dressing, and medication reminders—without skilled medical care—falls outside Medicare's coverage scope.

Medicare Part A coverage typically begins on the first day you receive care in a Medicare-certified SNF, provided you meet the other requirements. The facility must be Medicare-certified and your doctor must order the care. You cannot simply move into a nursing home and expect Medicare to cover it; there must be medical justification documented by your physician that skilled care is medically necessary.

The coverage period has time limits. Medicare covers up to 100 days in a benefit period (which runs from October 1 to September 30 each year for billing purposes). However, this doesn't mean you automatically get 100 days covered at no cost. The first 20 days are covered at 100% after you meet your Part A deductible. From day 21 to day 100, you pay a daily coinsurance amount while Medicare covers the remainder. After day 100, you pay the full cost until your benefit period ends.

Practical takeaway: Before assuming Medicare will cover nursing home care, confirm with the facility that it's Medicare-certified and that your situation involves skilled medical care, not just help with daily activities. Ask the facility's admissions team about your specific situation and what costs Medicare will and won't cover in your case.

What You Pay: Deductibles, Copays, and Coinsurance

Medicare nursing home coverage requires you to understand multiple cost-sharing amounts, and these numbers change yearly. For 2024, the Part A deductible is $1,632. This is what you pay out of pocket before Medicare's coverage kicks in for any Part A service, including skilled nursing facility care. This deductible applies once per benefit period (October 1 to September 30), not once per year.

Days 1-20 of SNF care are fully covered by Medicare after you've paid your deductible, meaning no additional copays or coinsurance on top of the deductible. However, this assumes you've already used up your Part A deductible through a hospital stay or another Part A service earlier in that benefit period. If the nursing home is your first Part A service in the benefit period, you'll pay the full $1,632 deductible before Medicare coverage starts.

From day 21 through day 100, Medicare requires a daily coinsurance payment. For 2024, this coinsurance is $408 per day. You pay this amount each day while Medicare covers the rest of your care. This represents one-quarter of the Part A deductible amount and reflects Medicare's cost-sharing model for extended care.

After day 100 in a benefit period, Medicare SNF coverage ends entirely. You become responsible for 100% of the facility's charges. Some people have supplemental insurance (Medigap) that covers some or all of these costs, but the guide covers Medicare's direct coverage only. Others may transition to Medicaid if they meet income and asset limits, but that's a separate program.

Additional costs exist beyond the facility's room and board charges. Medicare covers the SNF's medical services, but any services not covered by Medicare—such as phone service, television, personal grooming items, or specialized therapy beyond what's medically necessary—may be billed to you separately.

Practical takeaway: Before admission, ask the SNF for an estimate of your likely stay and calculate your out-of-pocket costs using the current deductible and daily coinsurance amounts. Keep track of which benefit period you're in—the dates matter significantly for your costs.

The Three Requirements for Coverage to Begin

Medicare doesn't cover nursing home care simply because you're 65 or older and on Medicare. Three specific requirements must be met simultaneously, and many people don't realize they haven't satisfied all of them until they're already admitted and receive unexpected bills.

The first requirement is a qualifying hospital stay. You must have been admitted to a hospital (not just the emergency department) and stayed overnight as an inpatient for at least three consecutive calendar days before your SNF admission. This means the clock starts at midnight when you're formally admitted as an inpatient, and the third day is the day you're discharged from the hospital. Many people believe an emergency room visit followed by admission counts as a qualifying stay, but the rule specifically requires three full calendar days as an inpatient in the hospital.

The second requirement is admission to the SNF within 30 days of hospital discharge. If you go home after the hospital and then enter a nursing home 35 days later, Medicare won't cover it based on that hospital stay. The timing window is strict. However, if you transfer directly from hospital to SNF, or if you spend a few days at home before being admitted to the SNF, you're within the window. The 30-day clock starts on the day you're discharged from the hospital.

The third requirement is that the SNF must be treating you for the same condition you were hospitalized for, or a condition that arose during your hospitalization. For example, if you were hospitalized for pneumonia and admitted to a SNF for respiratory therapy and recovery, that meets this requirement. If you were hospitalized for pneumonia but admitted to a SNF for physical therapy after an unrelated fall at home, Medicare may not cover it unless the hospitalization and SNF care are medically related.

A fourth often-overlooked element is that the SNF itself must be Medicare-certified. Not all nursing homes participate in Medicare. A facility may be excellent but simply not have Medicare certification. This certification status can be verified through Medicare's Nursing Home Compare tool on Medicare.gov.

Practical takeaway: Document your hospital discharge date and the medical reasons for both your hospitalization and SNF admission. If your SNF stay is within 30 days of a qualifying hospital stay for a related condition, you're likely to meet the requirements. If any of these conditions don't apply to your situation, ask the SNF's business office to clarify your coverage status before relying on Medicare to pay.

Understanding Benefit Periods and When Coverage Resets

Many people misunderstand how Medicare benefit periods work for nursing homes because they assume it works like a calendar year (January to December). It doesn't. Medicare benefit periods run from October 1 through September 30, and this affects your SNF coverage amounts and costs significantly.

Your Part A deductible resets once per benefit period, meaning you pay it only once every October 1 to September 30 cycle. If you had a hospital stay in March and paid your deductible, then entered a SNF in May of the same benefit period, you wouldn't pay another deductible for that SNF stay. However, if you were hospitalized in August and admitted to a SNF in September, then discharged and readmitted to a SNF in October, the October admission is a new benefit period with a fresh deductible to pay.

Your 100-day SNF coverage limit also resets per benefit period. If you use 60 days of SNF care between October 2023 and September 2024, you have 40 days remaining in that benefit period. When October 1, 2024 arrives, your counter resets to zero, and you have another full 100 days available in the new benefit period. However, if you're still in the SNF when the benefit period ends, your coverage doesn't automatically end on September 30. You continue using your remaining days into the new benefit period.

This system can create confusion at year-end transitions. If you're admitted to a SNF on August 15 and stay through October 31, your first 46 days (through September 30) count against your previous benefit period's 100 days. On October 1, a new benefit period begins, and your remaining stay counts against the new period's 100-day limit. You'll also owe a new Part A deduct
