Original Medicare (Part A and Part B) will pay for inpatient rehabilitation if it’s medically necessary following an illness, injury, or surgery once you’ve met certain criteria.

In some situations, Medicare requires a 3-day hospital stay before covering rehabilitation. Medicare Advantage plans also cover inpatient rehabilitation, but the coverage guidelines and costs vary by plan.

Recovery from some injuries, illnesses, and surgeries can require a period of closely supervised rehabilitation. Medicare covers your treatment in an inpatient rehabilitation facility as long as you meet certain guidelines.

The guidelines discussed in this article relate to inpatient medical or postsurgical rehabilitation — not inpatient rehabilitation for a substance use disorder. You can learn more about Medicare’s guidelines for the treatment of substance use disorders here.

Medicare Part A covers your inpatient care in a rehabilitation facility as long as your healthcare professional deems it medically necessary. In addition, you must receive care in a facility that’s Medicare-approved.

How long can you stay in rehab with Medicare?

You can stay in inpatient rehabilitation indefinitely. However, Medicare will only pay for the full cost for the first 60 days. A detailed breakdown of costs follows below.

Depending on where you receive your inpatient rehab therapy, you may need to have a qualifying 3-day hospital stay before your rehab admission. We’ll discuss that rule in more detail later.

If you’re enrolled in Original Medicare (Part A and Part B) in 2025, you’ll pay the following costs during each benefit period:

  • Days 1 through 60: You’ll be responsible for a $1,676 deductible. If you transfer to the rehab facility immediately after your hospital stay and meet your deductible there, you won’t have to pay a second deductible because you’ll still be in a single benefit period. The same is true if you’re admitted to a rehab facility within 60 days of your hospital stay.
  • Days 61 through 90: During this period, you’ll owe a daily copayment of $419.
  • Day 91 and onward: You’ll pay a daily copayment of $838 for each of your lifetime reserve days. You have 60 lifetime reserve days. After you’ve used them all, you’re responsible for all costs.

What is a benefit period?

Each benefit period begins the day you’re admitted to a hospital or skilled nursing facility as an inpatient and ends 60 consecutive days after your stay without further inpatient care.

If you return to the hospital and are admitted within 60 days of your previous stay, you’ll still be in that benefit period. However, a new benefit period begins if you return to the hospital after 60 days without care.

Costs with Medicare Advantage

If you have a Medicare Advantage (Part C) plan, your costs will vary depending on your insurer. If possible, talk with your plan advisor or insurance company in advance so you can prepare for any out-of-pocket costs.

If you think you may need long-term care, you can explore the available Medicare Advantage Special Needs Plans. These plans are designed to offer extra benefits for people with chronic health conditions and those enrolled in both Medicare and Medicaid.

Costs with Medigap

Adding Medigap (Medicare supplement) coverage could help you pay your coinsurance and deductible costs. Some Medigap plans also offer additional lifetime reserve days (up to 365 extra days).

You can search for plans in your area and compare coverage using Medicare’s plan finder tool.

During inpatient rehabilitation, a team of healthcare professionals will work together to help you function on your own again.

Your treatment plan will be tailored to your condition but may include:

  • assistance with orthotic or prosthetic devices
  • occupational therapy
  • physical therapy
  • psychological services
  • social services

Rehabilitation may occur in a special section of the hospital, a skilled nursing facility, or a separate rehabilitation facility.

Other things covered as part of inpatient rehabilitation include meals, prescription drugs you need during your stay, and other supplies.

Although Medicare covers your care during rehabilitation, it’s not intended to be long-term care. You can learn more about Medicare and long-term care facilities here.

To ensure Medicare covers your inpatient rehabilitation, follow the guidelines outlined below.

Make sure you’re enrolled in Medicare

You can first enroll during a 7-month window called the initial enrollment period. This period starts 3 months before you turn 65 years old and ends 3 months after your birth month.

Another opportunity to enroll is during Medicare’s open enrollment period from October 15 to December 7 each year.

If you’re considering a Medicare Advantage (Part C) plan, your enrollment period runs from January 1 through March 31 each year. Depending on your situation, you may also qualify for a special enrollment period.

Confirm your initial hospital stay meets the 3-day rule

Medicare covers inpatient rehabilitation care in a skilled nursing facility only after a 3-day inpatient stay at a Medicare-approved hospital.

It’s important that your healthcare professional write an order admitting you to the hospital. If you’ve spent the night in the hospital for observation or testing, that won’t count toward the 3-day requirement.

These 3 days must be consecutive, and any time you spent in the emergency room before your admission isn’t included in the total number of days. Your discharge day is also not included in the 3-day total.

The 60-day rule

Note that leaving an SNF facility could affect your coverage. You have the right to appeal a discharge decision. A break lasting more than 30 days requires a new 3-day hospital stay for continued SNF care, regardless of the previous condition. If a break lasts 60 consecutive days, your benefit period ends and renews with up to 100 days of coverage for SNF care.

If you’re having surgery, check Medicare’s “inpatient only” list

Some surgical procedures always require admission as an inpatient. The 3-day rule doesn’t apply to these procedures, and Medicare will cover your inpatient rehabilitation after the surgery. These procedures can be found on Medicare’s inpatient-only list.

In 2018, Medicare removed total knee replacements from the inpatient-only list, and in 2020, it removed total hip replacements. The 3-day rule now applies to both of those procedures.

If you have a Medicare Advantage plan, talk with your insurance provider to determine if your surgery is considered an inpatient-only procedure. Each plan’s coverage rules differ, and knowing whether the 3-day rule applies could save you a lot of money.

Verify that your doctor’s order includes the required information

To ensure Medicare coverage for your inpatient rehabilitation, your doctor will have to certify that you need the following:

  • access to a medical doctor 24 hours per day
  • frequent interaction with a doctor during your recovery
  • access to a registered nurse with a specialty in rehabilitation services
  • therapy for at least 3 hours per day, 5-7 days per week, which is known as the 3-hour rule
  • a multidisciplinary team to care for you, including a doctor, rehabilitation nurse, and at least one therapist

If you want to confirm you’re following Medicare procedures to the letter, you can contact Medicare directly at 800-MEDICARE (800-633-4227 or TTY: 877-486-2048).

Inpatient rehabilitation is goal-driven and intense. You and your rehab team will create a coordinated plan for your care. The primary aim will be to help you recover and regain as much functionality as possible.

Depending on your health condition, your team will include registered nurses specializing in rehab care, one or more physicians, and rehab therapists.

You might also receive assistance from psychologists, psychiatrists, or social workers who can help with your mental and emotional well-being.

You may work with a physical therapist to:

  • rebuild your strength and ability to move
  • increase your range of motion
  • decrease pain and swelling

You may work with an occupational therapist to:

  • learn how to use any medical devices you’ll need during recovery
  • perform the activities of daily living during your recovery
  • prepare for life at home after you’re discharged

You may work with a speech and language pathologist to:

  • rebuild your vocabulary and practice word retrieval
  • swallow food and drinks
  • learn new ways to communicate

Inpatient rehabilitation is often necessary if you’ve experienced one of these injuries or conditions:

Original Medicare and Medicare Advantage plans pay for inpatient rehabilitation if your doctor certifies that you need intensive, specialized care to help you recover from an illness, injury, or surgical procedure.

You might receive inpatient rehabilitative treatment in a dedicated rehab department inside a hospital, a skilled nursing facility, or a separate rehabilitation clinic or hospital.

You must meet certain important conditions in order for Medicare to cover your inpatient rehab. You’ll still have to pay for the cost of coinsurance and deductibles, even with Medicare coverage.

While you’re in rehab, a team of nurses, doctors, and therapists will provide your care. They can help you get back on your feet as quickly and safely as possible.
