How Long Does Medicare Pay for Swing Bed Care?

Medicare Part A pays for swing bed care for up to 100 days in each benefit period. The first 20 days are fully covered. Days 21 through 100 carry a daily coinsurance of $217 in 2026, and after day 100 Medicare pays nothing until a new benefit period begins.¹² Coverage can also end sooner if you no longer need daily skilled care.

Swing bed care is the arrangement that lets certain small, rural hospitals shift a bed from acute hospital use to skilled nursing or rehabilitation use without transferring you elsewhere. Medicare treats those days under the same rules it uses for a standalone skilled nursing facility stay, so the coverage timeline below is really the SNF benefit applied inside a hospital.¹

Days 1 Through 20

For the first 20 days of a covered swing bed stay, Medicare Part A pays 100% of covered services. You owe no coinsurance and no copay. Covered services include skilled nursing, physical therapy, occupational therapy, speech-language pathology, and related supplies.¹

Days 21 Through 100

Starting on day 21, you share the cost. The 2026 daily coinsurance is $217.² Medicare continues paying the balance of each day’s cost, but your share adds up. A full 80-day stretch of coinsurance days at that rate totals $17,360.

After Day 100

Once you hit day 100 in a single benefit period, Medicare’s contribution stops. The full daily cost falls to you unless another payer covers it. Coverage can also end well before day 100 if the facility or Medicare determines you no longer need daily skilled care. When physical therapy drops from daily sessions to three times a week, for example, the stay may be reclassified as custodial, and Medicare will stop paying at that point. The transition from skilled to custodial care is the most common reason coverage ends early.

What You Have to Qualify For First

The timeline only applies if you qualify for the benefit in the first place. Medicare requires all three of these before it will pay for swing bed care:³

A prior inpatient hospital stay of at least three consecutive days. The discharge day doesn’t count, and time in the emergency room or under observation doesn’t count.
Admission to the swing bed within 30 days of leaving the hospital.
A doctor’s certification that you need daily skilled nursing or skilled rehabilitation services. Help with bathing, dressing, or eating alone does not qualify.

The Observation Status Problem

The three-day rule is where most swing bed denials start, and the reason is observation status. You can be in a hospital bed for four days on IV medication and still not have a qualifying inpatient stay, because the hospital classified those days as outpatient observation. Observation time does not count toward the three-day inpatient requirement, no matter how long you are physically in the hospital.⁴

Hospitals must give you a written Medicare Outpatient Observation Notice (MOON) telling you when you’re under observation rather than admitted.⁵ Ask your doctor or a hospital patient advocate every day whether you are inpatient or outpatient.⁶ Once you’re discharged, changing that classification is very hard, and the cost of the swing bed stay lands on you.

The 100-Day Limit Resets by Benefit Period

The 100 days are counted per benefit period, not per calendar year. A benefit period starts the day you’re admitted as an inpatient and ends after you’ve been out of a hospital or skilled nursing facility for 60 consecutive days.⁷ Once that 60-day gap passes, a new benefit period begins and your 100 days reset.

The reset isn’t free. Each new benefit period also triggers a new Part A inpatient hospital deductible, which is $1,736 in 2026, and you would need another qualifying three-day inpatient stay before swing bed coverage starts up again.²

How Medigap Handles the Coinsurance

If you have a Medicare Supplement (Medigap) policy, it may pay some or all of the $217 daily coinsurance for days 21 through 100. Coverage varies by plan letter:⁸

Plans C, D, F, and G pay 100% of the skilled nursing facility coinsurance.
Plan L pays 75%.
Plan K pays 50%.
Plans A, B, M, and N do not cover this coinsurance.

Plans C and F are no longer available to people who turned 65 on or after January 1, 2020. Among plans still open to new enrollees, Plan G provides the most complete coverage of the swing bed coinsurance.⁸

If You Have Medicare Advantage

Medicare Advantage plans must cover at least the same benefits as Original Medicare, but they can add rules. Prior authorization before a swing bed admission is common, and missing that step can result in a denial even when you clearly meet the medical criteria.⁹ Some plans waive the three-day inpatient hospital stay requirement, but not all do.³ Call your plan’s member services line before discharge to confirm both the prior authorization process and whether the three-day rule applies.

Appealing If Coverage Ends Too Soon

Before your swing bed coverage ends, the facility must give you a Notice of Medicare Non-Coverage at least two days before the termination date.¹⁰ The notice explains how to request a fast appeal through a Beneficiary and Family Centered Care-Quality Improvement Organization (BFCC-QIO).

The deadline is short. You must contact the BFCC-QIO no later than noon the day before the termination date on the notice. The QIO reviews your records and issues a decision by the close of business the following day.¹¹ If the QIO agrees with you, coverage continues. If it agrees with the facility, you can still pursue a standard appeal, but you’ll be responsible for the cost of care in the meantime.

Paying for Care After Medicare Stops

When the 100 days are used up or skilled care is no longer needed, the daily cost is yours. Private-pay rates at skilled nursing facilities typically run from roughly $190 to $535 a day depending on location and level of care. Options include private health insurance with post-acute benefits, long-term care insurance, and personal savings. Medicaid may cover nursing home care for people who meet income and asset limits, though qualifying often requires spending down assets, and the rules vary by state. If you think you’ll need help beyond Medicare, contact your state Medicaid agency early rather than after coverage ends.
