Medicare covers nursing home care — but only temporarily, only under specific conditions, and only when the care involves skilled medical services. It does not cover long-term stays. It does not cover custodial care. And it ends far sooner than most families expect.
This is the most consequential misunderstanding in elder care financing. Nearly half of Americans over 65 believe Medicare will pay for an extended nursing home stay. It will not. Understanding exactly what Medicare does and does not cover — and when it stops — is essential before any placement decision.
The short answer
Medicare Part A covers up to 100 days of skilled nursing facility care per benefit period. The first 20 days are fully covered. Days 21 through 100 require a daily coinsurance payment. After day 100, Medicare pays nothing.
The average Medicare-covered nursing home stay lasts approximately 22 days. Most residents never come close to 100 days of coverage because Medicare stops paying when skilled care is no longer required — regardless of how many days remain in the benefit period.
What Medicare pays: the exact numbers
Period What you pay (2026) Days 1–20 $0 — Medicare covers 100% Days 21–100 $217 per day coinsurance (~$6,510/month) Day 101+ Everything — Medicare coverage ends Part A deductible (per benefit period) $1,736
A benefit period begins when you are admitted to a hospital and ends 60 consecutive days after you leave a hospital or skilled nursing facility. There is no annual limit on benefit periods — the 100-day clock resets each time a new benefit period starts. But the Part A deductible must be paid again each time.
Medigap policies (Medicare Supplement Plans C, F, and others) cover the $217/day coinsurance for days 21–100, effectively extending full coverage through the entire 100-day window. Medicare Advantage plans handle this coinsurance differently — some charge copays even for days 1–20 and most require prior authorization.
The three requirements that must all be met
Medicare will not pay for skilled nursing facility care unless all three of these conditions are satisfied:
1. A qualifying hospital stay of at least three consecutive inpatient days. The stay must be formal inpatient admission — not observation status. This distinction matters enormously: a patient can spend four nights in a hospital bed, receive round-the-clock care, and still be classified as "observation," which does not count. Always ask whether the admission is inpatient or observation. If it is observation, request a formal inpatient admission or understand that SNF coverage will not follow.
2. Admission to a Medicare-certified skilled nursing facility within 30 days of hospital discharge. Not all nursing homes are Medicare-certified, and the admission must occur within the 30-day window. The condition requiring SNF care must be related to the hospital stay (or a condition that arose during the SNF stay).
3. Daily skilled care is medically necessary. The resident must need skilled nursing or skilled therapy services — provided by or under the supervision of licensed professionals — on a daily basis. Physical therapy, occupational therapy, speech therapy, IV medications, wound care, injections, and complex medication management all qualify. Help with bathing, dressing, eating, and mobility does not qualify unless it is part of a skilled care plan.
If any one of these three conditions is not met, Medicare does not cover the stay. If skilled care needs end on day 14, Medicare stops on day 14 — not day 100.
The 3-day rule: exceptions that now cover most beneficiaries
The three-day inpatient hospital stay requirement has been the most criticized rule in Medicare nursing home coverage. As of 2026, the rule remains in effect for Original Medicare, but multiple exceptions now cover the majority of beneficiaries:
Medicare Advantage plans (~54% of Medicare beneficiaries) can waive the 3-day rule entirely. Roughly 92% of MA plans exercise this authority, substituting prior authorization instead.
ACO waivers allow Medicare Shared Savings Program participants in two-sided risk tracks to waive the rule for beneficiaries at SNFs rated 3+ stars. Over 53% of Traditional Medicare beneficiaries are now attributed to ACOs.
The TEAM Model (launched January 2026) waives the rule for five specific surgical procedures — joint replacement, hip fracture, spinal fusion, CABG, and major bowel procedures — at participating hospitals.
Combined, over 70% of Medicare beneficiaries now have coverage through programs that can bypass the 3-day rule. Ask your hospital discharge planner which pathway applies.
Skilled care vs. custodial care: the line that matters most
This is the distinction that determines whether Medicare covers a nursing home stay or does not. It is worth stating plainly:
Skilled care requires the knowledge, judgment, and skills of a licensed nurse or therapist. Examples: IV therapy, wound care requiring assessment, physical therapy to restore function after a fracture, tube feeding management, complex medication regimens requiring skilled monitoring.
Custodial care is help with the activities of daily life — bathing, dressing, eating, toileting, transferring, and mobility — that does not require licensed medical personnel. A nursing aide providing custodial care is performing essential, demanding work. Medicare does not cover it.
Most long-term nursing home residents need custodial care. They need help getting out of bed, getting to the bathroom, getting dressed, and eating meals. Medicare considers this personal care, not medical care, and it is excluded from coverage regardless of how necessary it is or how long the person has been a Medicare beneficiary.
The Jimmo exception: The 2013 Jimmo v. Sebelius settlement established that Medicare must cover skilled maintenance therapy — skilled services to maintain function or prevent decline, even when improvement is not expected. A therapist providing skilled care to keep a Parkinson's patient from losing the ability to swallow is performing a covered service. This settlement is underenforced, and families should know it exists when a facility or insurer claims coverage requires demonstrated improvement.
What Medicare Advantage changes
More than half of Medicare beneficiaries are now enrolled in Medicare Advantage (Part C) plans, and the rules for SNF coverage differ in important ways:
No 3-day hospital stay required in most MA plans — but prior authorization is almost always required instead. The plan must approve the SNF admission before or shortly after it occurs.
Network restrictions apply. MA plans typically cover only in-network skilled nursing facilities. An out-of-network placement may not be covered or may require emergency exceptions.
Cost-sharing varies. Unlike Original Medicare's standardized $0 for days 1–20, some MA plans charge daily copays from day one. Others offer $0 copays for the full 100 days. The specific plan documents control.
New 2026 protections: CMS rules effective in 2026 require MA plans to make standard prior authorization decisions within 7 calendar days (72 hours for expedited requests) and prohibit retroactive denials of approved inpatient admissions except for fraud.
If your family member has Medicare Advantage, call the plan before admission to confirm SNF coverage, network status of the facility, cost-sharing amounts, and prior authorization requirements. Do not assume MA coverage mirrors Original Medicare.
Five things families get wrong
"Medicare covers nursing home care." It covers skilled nursing facility care — temporarily, conditionally, and only when skilled services are needed daily. It does not cover long-term custodial nursing home care under any circumstances.
"We have 100 days." You have up to 100 days if skilled care is needed every single day. The average stay is 22 days. Medicare can and does end coverage mid-stay when skilled care needs resolve.
"A hospital stay qualifies us." Only a formal inpatient admission of three or more consecutive days qualifies under Original Medicare. Observation status — even multi-day observation — does not.
"Medigap covers what Medicare doesn't." Medigap covers Medicare's cost-sharing (the $217/day coinsurance, the Part A deductible). It does not cover services Medicare excludes. If Medicare does not cover custodial care, Medigap does not either.
"My parent is improving, so Medicare will keep paying." Medicare does not stop at improvement — it stops when daily skilled care is no longer needed. A patient can improve significantly and still need skilled care (coverage continues), or improve slightly and no longer need skilled care (coverage ends). The trigger is the care need, not the trajectory.
What happens when Medicare stops
When Medicare coverage ends — whether at day 15 or day 100 — the financial responsibility shifts entirely to the resident and family. At that point, the options are:
Private pay from savings, retirement accounts, and income. At median national costs, this runs $9,500 to $10,800 per month.
Long-term care insurance benefits, if the elimination period has been satisfied.
VA Aid and Attendance pension for eligible veterans and surviving spouses — up to $2,874/month, tax-free.
Medicaid, once assets are depleted to the eligibility threshold ($2,000 in most states). Medicaid covers custodial nursing home care indefinitely with no time limit.
The transition from Medicare to the next payment source is the most financially dangerous moment in a nursing home stay. Families who have not planned for it face an abrupt shift from $0/day to $350+/day with no warning beyond the Medicare termination notice — which arrives with limited appeal time.
