Medicare covers rehabilitation facility stays for a limited time, not indefinitely

Medicare Part A pays for inpatient rehabilitation facility (IRF) stays after a hospital stay, but only for as long as you need skilled care to recover from an illness or injury. The length of coverage depends on your medical condition, your progress in therapy, and whether Medicare's medical reviewers determine the care is still medically necessary. Most stays last between two and three weeks, though some people stay longer and others leave sooner.

The key rule is this: Medicare pays only while you are making progress toward a specific medical goal — like regaining the ability to walk, managing a new amputation, or recovering from a stroke. Once your doctor determines you have reached the point where you can continue recovery at home or in a less intensive setting, Medicare stops paying for the facility bed.

Key Takeaways

  • Medicare Part A covers inpatient rehabilitation facility care after a hospital stay, but only while you are making measurable progress toward recovery.
  • You must have been admitted to a hospital for at least three consecutive days before Medicare will pay for a rehabilitation facility stay.
  • The facility's medical team and Medicare's reviewers decide when your stay ends, not a fixed calendar date — this can happen sooner or later than you expect.
  • You pay a daily copay (currently $194.50 per day for days 1–20, and $389 per day for days 21–100 in 2024, though these amounts change yearly) once you meet your Part A deductible.
  • If you disagree with the decision to discharge you, you have the right to appeal and can stay in the facility while the appeal is being reviewed.

The three-day hospital stay requirement

Before Medicare will pay for a rehabilitation facility, you must have been admitted to a hospital as an inpatient for at least three consecutive days. The day you are discharged from the hospital does not count toward this requirement. This rule exists because Medicare considers rehabilitation facility care a continuation of hospital-level treatment, not a separate benefit.

If you spent three days in the hospital and were then transferred to a rehabilitation facility within one calendar day of discharge, you meet the requirement. If you go home first and then enter a rehabilitation facility days or weeks later, that earlier hospital stay may no longer count, and you would need a new hospital admission to may have access to.

How Medicare decides when your stay ends

Your rehabilitation facility stay ends when one of two things happens: either your medical team determines you no longer need inpatient rehabilitation, or Medicare's medical reviewers decide the care is no longer medically necessary. In practice, both usually happen at the same time, because the facility's doctors and Medicare's reviewers are looking at the same medical facts.

The facility's care team meets regularly to assess your progress. They measure whether you are making gains in physical therapy, occupational therapy, or other skilled services. If your progress plateaus — meaning you stop improving — or if you reach a point where you can safely continue recovery at home with outpatient therapy or home health services, the team will recommend discharge. Medicare's utilization review process checks whether this recommendation aligns with Medicare's coverage rules.

This is why the length of stay varies so much from person to person. Someone recovering from a hip replacement might need two weeks of intensive therapy and then be ready to go home. Someone recovering from a severe stroke might need four weeks or more. The facility does not keep you longer just because Medicare has not yet hit a payment limit — they keep you only as long as the medical facts support it.

What happens if you disagree with the discharge decision

If you or your family believe you still need inpatient rehabilitation care when the facility tells you that you are being discharged, you have the right to appeal. You do not have to leave the facility while your appeal is being decided. This is called expedited review, and it is a formal process, not a conversation with your doctor.

To appeal, you must notify the facility in writing before you are discharged, or you can ask the facility's patient advocate to help you file. The facility will then request that an independent medical reviewer (not employed by Medicare or the facility) examine your medical record and decide whether the discharge is appropriate. This review usually takes one business day. If the reviewer agrees with you, Medicare continues to pay. If the reviewer agrees with the facility, you are responsible for the cost of care from that point forward.

Many people do not know they can appeal, and many facilities do not emphasize this right. Ask the facility's social worker or patient advocate about the appeal process before you are discharged.

The difference between inpatient rehabilitation and other facility types

Medicare covers inpatient rehabilitation facilities (IRFs) under Part A, but it also covers other types of facilities under different rules. A skilled nursing facility (SNF) is different from an IRF. SNFs provide less intensive therapy and are often used for longer stays — Medicare covers up to 100 days per benefit period, though you pay a copay after day 20. An IRF is for people who need intensive, coordinated rehabilitation from multiple therapy disciplines and can tolerate three or more hours of therapy per day.

Your hospital discharge planner will recommend the type of facility that matches your medical needs. If you are unsure whether you are going to an IRF or a SNF, ask the hospital before you leave — the two have very different payment rules and length-of-stay patterns.

What you pay during your rehabilitation stay

Once you have met your Part A deductible for the year, you pay a daily copay for each day in the rehabilitation facility. The copay amount changes each year. For 2024, you pay $194.50 per day for days 1 through 20, and $389 per day for days 21 through 100. After 100 days in a benefit period, you pay all costs out of pocket.

These copay amounts explore only to inpatient rehabilitation facilities. Skilled nursing facilities have a different copay structure. If you are on a limited income, ask the facility's financial counselor whether you might be may be able to access for Medicaid to help cover these costs, or whether the facility has a financial information program.

Planning for life after rehabilitation

Before you are discharged, the facility's care team should work with you and your family to plan what comes next. This might include home health services (which Medicare also covers for a limited time), outpatient therapy, equipment you need at home, or changes to your living space. The social worker should discuss whether you will need a caregiver, whether you can safely live alone, and what community resources are available to you.

Ask the facility to provide written discharge instructions and a list of all the therapy and medical services you were receiving. This information helps your primary care doctor and any outpatient therapists understand what you have already accomplished and what you still need to work on. Do not wait until the day you leave to ask these questions — start the conversation at least a few days before discharge.

Frequently Asked Questions

Can Medicare pay for more than 100 days in a rehabilitation facility?

No. Medicare Part A covers a maximum of 100 days in a skilled nursing facility per benefit period, and inpatient rehabilitation facilities do not have a specific day limit, but coverage ends when you no longer need inpatient-level care. After 100 days in any combination of hospital and facility care within a benefit period, you pay all costs yourself unless you have supplemental insurance.

What if I need rehabilitation but was not in the hospital for three days first?

Medicare will not pay for inpatient rehabilitation facility care without a prior three-day hospital stay. You might be able to receive rehabilitation services through outpatient therapy, home health services, or a skilled nursing facility if you meet other criteria, but these have different coverage rules. Talk to your doctor about what options are available to you.

Does my rehabilitation facility stay count toward my Part A deductible?

No. Your three-day hospital stay counts toward your Part A deductible. Once you have met the deductible during your hospital stay, you then pay the daily copay for the rehabilitation facility. The deductible and the facility copay are separate costs.

Can the facility discharge me if I am still making progress?

The facility can discharge you when your medical team and Medicare's reviewers determine that you no longer need inpatient-level care, even if you are still making some progress. The standard is whether inpatient rehabilitation is medically necessary, not whether you could benefit from more therapy. If you disagree, you can appeal before you leave.

What happens to my medications and medical equipment when I leave the facility?

The facility should send you home with a list of all your current medications and instructions on how to take them. Medicare Part D (prescription drug coverage) covers most medications once you leave. For medical equipment like walkers or wheelchairs, Medicare Part B may cover some items if your doctor prescribes them. Ask the facility's discharge planner which equipment is covered and how to order it before you go home.
