How long does Medicare pay for nursing home care? The 100-day rule and what really happens

Short answer

Medicare pays for up to 100 days of skilled nursing facility care per benefit period after a qualifying three-day inpatient hospital stay. Days 1-20 are covered at $0. Days 21-100 have a daily coinsurance of $217.00 in 2026. Day 101 and beyond are your responsibility — usually paid by Medicaid, long-term care insurance, or private pay. Medicare does not pay for long-term custodial nursing home care.

What Medicare’s nursing home benefit actually covers

Medicare’s nursing home benefit is narrower than most families expect. It is Part A coverage of a skilled nursing facility (SNF) — a short-term post-hospital rehabilitation stay, not a permanent residence.

SNF vs long-term nursing home

The distinction matters because most nursing homes in the United States offer both:

• SNF care — short-term. The patient needs skilled care (nursing, therapy) on a daily basis for a condition that requires professional attention. Medicare Part A covers up to 100 days per benefit period.
• Long-term custodial care — ongoing residential help with daily activities like bathing, dressing, and mobility. Medicare does not cover this. Medicaid, long-term care insurance, and private pay are the main sources.

A single physical nursing home can house both — a resident may occupy an SNF bed for 60 days after a hip surgery, then transition to a long-term custodial bed on the same campus. The billing changes even though the person and the room may not.

What SNF care includes at $0 to you

When you qualify and are within days 1-20, Medicare covers:

• Skilled nursing services (wound care, IV therapy, injections, feeding tubes)
• Physical, occupational, and speech therapy
• Medical social services
• A semi-private room and meals
• Medications administered as part of your care
• Ambulance transportation if medically necessary

Note that a private room is not covered unless medically necessary. If you request a private upgrade, you pay the difference.

The 3-day inpatient rule and the observation-status trap

To activate Medicare’s SNF benefit, the person must have a hospital stay of at least three consecutive days as an inpatient — and then be admitted to a Medicare-certified SNF within 30 days of discharge for the same or a related condition.

The word “inpatient” is where things go wrong. Hospitals sometimes keep patients under observation status — technically outpatient — for a night or two while they decide what to do. Observation days look and feel identical to inpatient days from the patient’s side, but they do not count toward the three-day rule. A patient who spends four days in the hospital as an observation patient and then transfers to an SNF will typically be denied Medicare SNF coverage.

Two things reduce this risk:

• Ask the hospital directly, in writing, whether the person’s status is inpatient or observation. Hospitals are required to issue a Medicare Outpatient Observation Notice (MOON) to observation patients after 24 hours — but confirming actively saves surprises.
• If observation status is the barrier and the person’s condition warrants inpatient admission, a patient advocate or the hospital attending physician can request a status change. This is a case-by-case negotiation and works best when raised early.

The 100-day rule in detail

Once the SNF benefit is activated, the coverage-and-cost schedule follows a fixed pattern:

• Days 1-20: $0 to you. Medicare pays 100% of the covered amount.
• Days 21-100: $217.00 per day in 2026 as your coinsurance. Across days 21 through 100, this reaches up to about $17,360 out of pocket if you stay through day 100. Some Medicare Supplement (Medigap) plans cover this coinsurance; check yours.
• Day 101 and beyond: Medicare pays $0. You are responsible for the full cost unless another payer is in place.

The 100 days are per benefit period — a Medicare-specific measurement that starts when you are admitted to inpatient hospital or SNF care and ends after 60 consecutive days without skilled care.

When does the 100-day clock reset?

A new benefit period can begin — and with it a fresh 100 days of SNF eligibility — but only under specific conditions.

• 60 consecutive days without any skilled care. If the person leaves the SNF, goes home, and does not need skilled nursing or therapy for a full 60 days, a new benefit period begins the next time they are hospitalized.
• A new qualifying inpatient hospital stay after the 60-day gap. The hospital stay must again be at least three inpatient days for the same rules to apply.

What does not reset the clock:

• A brief break from skilled care (a weekend home, a few days between therapy sessions).
• Being discharged from an SNF but continuing to receive skilled home health care.
• Switching from an SNF to a different SNF within the same benefit period.

If you are unsure whether a new benefit period has begun, ask the SNF business office or call 1-800-MEDICARE with the person’s information handy.

Medicare Advantage and the 100-day rule

Medicare Advantage (Part C) plans must cover SNF care at the same minimum level as Original Medicare — but they can add rules of their own.

Common differences:

• Prior authorization. Many MA plans require pre-approval before an SNF admission. A weekend hospital discharge sometimes waits for Monday approval, delaying transfer.
• Network restrictions. MA plans typically require the SNF to be in-network. If the preferred SNF is out of network, coverage may be reduced or denied.
• Early termination. MA plans sometimes issue termination notices well before day 100, arguing the person no longer needs skilled care. These decisions can be appealed with the same NOMNC and BFCC-QIO process below.
• Different cost structure. Some MA plans have a per-day copay for days 1-20 (instead of $0), then a variable structure through day 100. Check your specific plan’s Evidence of Coverage.

If you are on an MA plan and are heading toward an SNF stay, call the plan directly to confirm prior authorization, network status, and cost sharing before admission.

Does Medicare cover nursing home care for specific conditions?

The 100-day rule applies regardless of diagnosis. What varies is whether the condition creates a skilled need that qualifies at all, and how long the skilled need typically continues.

• Post-surgical recovery (hip, knee, cardiac surgery). Most reliably qualifies. Therapy typically continues for several weeks.
• Stroke. Strong qualifier. Physical, occupational, and speech therapy can span the full 100 days for significant strokes.
• Wound care requiring skilled nursing. Qualifies when wounds cannot be managed at home.
• IV therapy, feeding tubes, tracheostomy care. Qualifies as long as the skilled need continues.
• Dementia (Alzheimer’s and related). Qualifies only if there is a co-occurring skilled need (recovery from a fall, wound care, therapy after a hospital stay). Dementia alone is not a Medicare-covered condition for SNF care because the primary need is custodial — help with daily activities.
• Parkinson’s disease. Qualifies when the person has therapy needs (mobility, speech, swallowing) or is recovering from a Parkinson’s-related fall or hospitalization. Long-term care for advancing Parkinson’s follows the same rules as dementia — Medicare covers the medical episodes, not the ongoing custodial care.
• End-stage heart failure or COPD. Qualifies during acute episodes requiring skilled nursing. For end-of-life care in a nursing home, hospice under Part A is often the more relevant benefit.

The pattern to remember: Medicare covers skilled need on a per-episode basis. It does not cover care built around a diagnosis alone.

What happens on day 101

The day Medicare stops paying can feel abrupt. Care that was $0 yesterday carries the facility’s full rate today, and the family is looking at a new bill starting immediately. Options at this point:

• Medicaid long-term care — the largest public payer for long-term nursing home care. Requires a financial spend-down, a look-back on transfers of up to five years in most states, and a level-of-care assessment. The Community Spouse Resource Allowance protects up to $162,660 in 2026 for a spouse remaining at home.
• Long-term care insurance, if the person has a policy. Triggers usually require 2+ activities of daily living or significant cognitive impairment. Elimination periods typically run one to three months before benefits begin.
• VA Aid & Attendance, for eligible veterans and surviving spouses — a monthly pension supplement for those who need the regular help of another person with daily activities. Maximum rates are set by the VA and change every year; confirm the current amount with the VA or an accredited veterans service officer before counting on it.
• PACE (Program of All-Inclusive Care for the Elderly) — for people 55+ who need nursing-home level of care but can remain in the community. Availability is limited to the areas where a PACE organization operates, so check whether one serves your address.
• Life insurance conversions — accelerated death benefit riders, life settlements, and viatical settlements can convert a permanent life policy into care funding.
• Private pay — from savings, income, or the sale of assets. Rates vary widely by region and room type, and private rooms cost more than semi-private. Ask the facility for its current daily and monthly rate in writing before day 101.

What to do if Medicare denies or ends coverage early

If the facility issues a Notice of Medicare Non-Coverage (NOMNC) before you expected — before day 100, or unexpectedly during the stay — you have specific rights.

• The NOMNC must arrive at least two calendar days before termination. It lists the last covered day and explains the right to expedited review.
• File an expedited review with the BFCC-QIO by noon the day before termination. Care continues at $0 during the review.
• The BFCC-QIO decision typically arrives within 72 hours. If it reverses the termination, Medicare continues to pay. If it upholds, you owe from the date noted forward.
• Beyond the expedited BFCC-QIO review, the 5-level Medicare appeal path is available: redetermination, reconsideration, ALJ hearing (2026 threshold: $200), Medicare Appeals Council, and Federal District Court (2026 threshold: $1,960). Full mechanics: Medicare appeals process guide.

If you did not receive a NOMNC at least two days before the termination date, that is a procedural issue you can raise with the facility administrator, the plan (for MA), and — if unresolved — the state long-term care ombudsman program.

How Baba helps at the 100-day cliff

At Baba, our patient advocates help families navigate the SNF-to-day-101 transition every week. Three ways an advocate makes the difference:

• Verify the 3-day inpatient status while the person is still in the hospital, so SNF eligibility is not lost to a preventable observation-status issue.
• Read the NOMNC and file the expedited review if the termination date arrives earlier than expected. The timing is tight and the paperwork is standardized.
• Map the day-101 funding paths for your specific situation — Medicaid eligibility in your state, LTC insurance triggers, VA benefits, and family financial capacity — so the transition does not become a forced default.

If you are looking at a nursing home stay soon or already in one, we can help you understand where the person is in the 100-day cycle and what to plan for next.

Frequently asked questions

How long will Medicare pay for a nursing home?

Up to 100 days per benefit period in a Medicare-certified skilled nursing facility, after a qualifying three-day inpatient hospital stay. Days 1-20 are $0 to you. Days 21-100 have a coinsurance of $217.00 per day in 2026. Day 101 and beyond are not covered by Medicare.

Does Medicare cover nursing home costs?

Medicare covers up to 100 days of skilled nursing facility care per benefit period. Long-term custodial nursing home care — where the person needs ongoing help with daily activities rather than skilled nursing or therapy — is not covered.

What’s the 100-day SNF rule?

Medicare Part A covers up to 100 days of skilled nursing facility care per benefit period. The person must have had a qualifying three-day inpatient hospital stay and be admitted to the SNF within 30 days. The first 20 days are $0. Days 21-100 have a daily coinsurance ($217.00 in 2026). The clock resets after 60 consecutive days without skilled care.

What happens on day 101 in a nursing home?

Medicare stops paying. Options include Medicaid long-term care (after a spend-down and a look-back of up to five years), long-term care insurance if the person has a policy, VA Aid & Attendance for eligible veterans, PACE for community-eligible residents, life insurance conversions, and private pay.

Does Medicare pay for long-term nursing home care?

No. Medicare’s skilled nursing benefit is short-term rehabilitation. Long-term custodial nursing home care is paid primarily by Medicaid (for eligible residents), long-term care insurance, or private savings. A single facility may offer both — SNF and long-term — but the payer changes at the transition.

Does Medicare cover memory care in a nursing home?

Only if there is a co-occurring skilled need. Memory care as a general residential setting for dementia is a custodial service that Medicare does not cover. If a person with dementia is admitted to an SNF after a qualifying hospital stay for wound care, therapy after a fall, or another skilled need, Medicare covers the skilled episode under the standard 100-day rule.

Does Medicare pay for a nursing home for Parkinson’s disease?

Yes, when there is a specific skilled need such as post-fall recovery, therapy for mobility or swallowing, or wound care. Medicare does not cover long-term custodial care that many Parkinson’s patients eventually need. Advancing Parkinson’s typically transitions to Medicaid, LTC insurance, or private pay for the residential care portion.
