How many weeks of rehab will Medicare pay for?

Editorial team Published on

Medicare pays for up to 14 weeks (100 days) of short-term rehabilitation in a skilled nursing facility per benefit period, or up to 13 weeks (90 days) in an inpatient rehabilitation hospital.

Coverage depends entirely on whether your doctor certifies that you need daily skilled care and continue to show progress. If your condition improves and you "plateau" or stop making gains, Medicare can end coverage before the maximum time limit is reached.

Coverage Breakdown by Facility Type

  • Skilled Nursing Facility (SNF):
    • Covered for up to 100 days (about 14 weeks) per benefit period.
    • Days 1–20: 100% covered by Medicare with a $0 copay.
    • Days 21–100: You pay a daily coinsurance ($209.50 per day).
    • Requirement: You must have a prior inpatient hospital stay of at least 3 consecutive days.
  • Inpatient Rehabilitation Facility (IRF):
    • Covered for up to 90 days per benefit period, with an option to use lifetime reserve days for up to 150 days total.
    • Requirement: You must be able to tolerate at least 3 hours of therapy per day, 5 to 7 days a week.
  • Outpatient Therapy:
    • Medicare Part B covers physical, occupational, or speech therapy.
    • There is no annual limit on how many weeks or sessions you can receive, as long as your doctor proves it remains medically necessary.

How long will Medicare allow you to stay in a rehab facility?

Medicare covers up to 100 days of short-term rehab in a Skilled Nursing Facility per benefit period, or covers intensive inpatient rehabilitation in an Inpatient Rehabilitation Facility for up to 150 days with specific limitations.

Skilled Nursing Facility (SNF) Rehab

  • Duration: Up to 100 days per benefit period.
  • Days 1–20: 100% covered by Medicare after you pay your Part A deductible.
  • Days 21–100: You pay a daily coinsurance amount.
  • After Day 100: Medicare pays nothing, and you pay all costs.
  • Rules: You must have a qualifying 3-day inpatient hospital stay prior to admission and need daily skilled care. Coverage can end early if you stop making progress.

Inpatient Rehabilitation Facility (IRF) Care

  • Duration: Up to 150 days per benefit period.
  • Days 1–60: Fully covered after the Part A deductible.
  • Days 61–90: You pay a daily copay.
  • Days 91–150: Uses your 60 lifetime reserve days with a higher daily copay.
  • After Day 150: You pay all costs.
  • Rules: Requires intensive therapy (typically 3 hours a day, 5 days a week) and doctor certification.

How many days does Medicare pay 100% for rehab?

Medicare Part A pays 100% of the cost for the first 20 days of rehabilitation in a skilled nursing facility (SNF) per benefit period.

Skilled Nursing Facility (SNF) Rehab Coverage

  • Days 1–20: 100% covered by Medicare ($0 copay/coinsurance).
  • Days 21–100: Medicare covers part of the cost, but you must pay a daily coinsurance amount.
  • After Day 100: Medicare provides zero coverage, and you pay 100% of the cost.

Inpatient Rehabilitation Facility (IRF) Coverage

If your rehab takes place in a distinct inpatient rehabilitation hospital or unit rather than a skilled nursing facility, the cost structure is different:

  • Days 1–60: Covered in full after you pay the Inpatient Hospital Care Coverage Part A deductible ($1,736 in 2026), meaning $0 per-day costs after the deductible.
  • Days 61–90: You pay a daily coinsurance ($434 per day in 2026).
  • Days 91–150: You pay a higher daily coinsurance ($868 per day in 2026) using your lifetime reserve days.

Key Requirements

  • 3-Day Hospital Stay: You must have an official, consecutive 3-day inpatient hospital stay (not just observation) before being admitted for rehab.
  • Medical Necessity: A doctor must certify that you need daily skilled therapy. If you stop improving or "plateau," Medicare may cut off coverage before the 100 days end.

Why would Medicare deny rehab?

Medicare (specifically private Medicare Advantage plans) often denies rehab coverage because they determine the patient can safely recover at home or manage care at a lower level.

📊 Common Reasons for Denial

  • 💡 Lower level of care: Believing needs can be met at home or via outpatient therapy.
  • 💡 Financial incentives: Fixed-payment structures reward plans for spending less on expensive post-acute care.
  • 💡 Insufficient documentation: Referring provider notes lack clear evidence of medical necessity or recovery prognosis.
  • 💡 Lack of active participation: Patient is deemed unable or unwilling to meaningfully engage in therapy.
  • 💡 Automated reviews: Outside contractors use strict guidelines or automated tools that trigger high initial denial rates.

✅ Steps to Fight a Denial

  • 🗓 File a fast appeal: Request an immediate review through your Medicare Advantage plan or hospital discharge team.
  • 📌 Gather strong evidence: Collect detailed physical/occupational therapy notes, physician support letters, and specific daily safety risks.
  • 🔎 Highlight safety issues: Explicitly document fall risks, cognitive confusion, or severe caregiver limitations.

What is the Medicare 100-day rehab rule?

The Medicare 100-day rehab rule is a Medicare Part A benefit that covers short-term care in a skilled nursing facility (SNF) after a hospital stay, but it only pays "up to" 100 days and is not a guaranteed 100-day vacation or stay.

Key Requirements

  • 3-Day Inpatient Stay: You must have an official inpatient hospital stay of at least three consecutive days (time spent in "observation status" does not count).
  • 30-Day Window: You must enter a Medicare-certified skilled nursing facility within 30 days of leaving the hospital.
  • Skilled Care Need: A doctor must certify that you need daily skilled nursing or therapy services (like physical or occupational therapy).

Cost Breakdown

  • Days 1–20: Medicare pays 100% of the approved costs ($0 copay).
  • Days 21–100: You pay a daily coinsurance amount ($217 per day in 2026), while Medicare covers the rest.
  • Day 101 and Beyond: Medicare pays nothing, and you pay all costs.

Why Coverage Might End Early

  • No Progress: Coverage stops if you stop making measurable progress or no longer need daily skilled care, even if you have not used all 100 days.
  • Custodial Care: Medicare does not pay for long-term custodial care (help with daily living activities like bathing or dressing when no medical recovery is expected).

What are 5 treatments that Medicare doesn't cover?

Original Medicare does not cover routine dental care, routine eye exams and eyeglasses, hearing aids and fittings, long-term (custodial) care, and routine foot care.

Uncovered Treatments and Services

  • Routine dental care: Cleanings, fillings, tooth extractions, root canals, and dentures are generally excluded.
  • Routine vision care: Regular eye exams, prescription eyeglasses, and contact lenses are not paid for, though exceptions exist for conditions like cataracts or diabetes.
  • Hearing aids: Routine hearing tests, hearing aid devices, and fittings are entirely out-of-pocket under Original Medicare.
  • Long-term care: Ongoing assistance with daily living activities—such as bathing, dressing, and eating in a nursing home or at home—is not covered unless it is short-term skilled rehabilitation.
  • Routine foot care: General foot maintenance like trimming toenails or removing corns and calluses is excluded, except for specific medical necessities related to diabetes.

What to do when Medicare runs out for rehab?

When Medicare rehab coverage ends, you must either transition to an alternative payment method, appeal the decision, or plan for discharge. Original Medicare covers up to 100 days in a skilled nursing facility per benefit period (100% for the first 20 days, with coinsurance for days 21–100), and stops entirely after day 100.

Immediate Steps to Take

  • Review the Notice of Medicare Non-Coverage: The facility must give you this written notice before your coverage stops, explaining why your care is no longer covered.
  • File a Fast Appeal: If you believe you still need skilled care and that coverage is ending prematurely, you can request an expedited appeal through your local Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) by noon of the day before coverage ends.
  • Check Your Day Count: Contact the facility’s billing department to confirm exactly which day of your benefit period you are on and whether lifetime reserve days are available.

Options for Covering Continued Care

  • Medigap (Medicare Supplement Insurance): If you have a standardized Medigap policy, it may cover out-of-pocket coinsurance costs for days 21–100 or extend inpatient coverage limits, though it will not pay for care in settings that Medicare does not recognize.
  • Medicaid: If personal savings are depleted or if income and assets meet low-income thresholds, Medicaid can kick in to cover long-term or extended care. Many individuals qualify for dual eligibility without realizing it.
  • Private Pay and Financing: You can pay out-of-pocket on a daily or monthly basis if extended recovery is required before returning home. Ask the facility about sliding-scale fees, nonprofit financial assistance, or custom payment plans.
  • Transition to Home Health or Outpatient Therapy: If inpatient care is no longer medically necessary, transition safely by utilizing Medicare Part B for outpatient physical, occupational, or speech therapy.

What is the 60% rule in rehab?

The 60% rule in rehabilitation is a Medicare regulation that requires at least 60% of a facility’s patient population to have a primary diagnosis or comorbidity requiring intensive treatment for one of 13 specific medical conditions.

Overview of the Rule

  • Purpose: Established by the federal government, it ensures that Inpatient Rehabilitation Facilities (IRFs) are used primarily for patients who need intensive, specialized care rather than general nursing care.
  • Compliance: Facilities are evaluated annually by Medicare contractors. If a facility falls below the 60% threshold, it risks losing its specialized IRF payment classification and status.

The 13 Qualifying Conditions

To meet the threshold, patients must be treated for one of these specific diagnostic categories:

  • Stroke
  • Spinal cord injury
  • Congenital deformity
  • Amputation
  • Major multiple trauma
  • Fracture of the hip
  • Brain injury
  • Burns
  • Active polyarthritis
  • Systemic vasculitides with joint involvement
  • Severe or advanced osteoarthritis
  • Certain neurological disorders
  • Specific knee or hip replacements (such as bilateral replacements, or meeting specific age and body mass index criteria)

What are the requirements for Medicare to cover rehab?

Medicare covers rehabilitation services—including physical, occupational, and speech therapy—when a doctor certifies that the care is medically necessary.

General Requirements

  • Doctor's Order: A physician must order and certify the specific rehabilitation plan.
  • Medicare-Approved Facility: The care must be provided by a certified facility or qualified provider.
  • Potential for Improvement: The treatment must help you recover, improve, or maintain your current function.

Inpatient Rehabilitation Facility (IRF) Requirements

To qualify for an inpatient stay at a specialized rehabilitation hospital or unit under Medicare Part A, you must meet these rules:

  • Intensive Therapy: You need at least 3 hours of therapy per day, 5 to 7 days a week (known as the "3-hour rule").
  • Medical Supervision: You require active, ongoing oversight from a doctor.
  • Coordinated Care: Your treatment must involve a multidisciplinary team (physicians, nurses, and therapists).

Skilled Nursing Facility (SNF) Requirements

If you need short-term rehab in a skilled nursing facility after an injury or surgery:

  • Hospital Stay Rule: You generally must have a formal, consecutive 3-day inpatient hospital stay (time spent in observation or the ER does not count).
  • Daily Skilled Care: You must require skilled nursing or daily therapy that can only be safely provided in that setting.

Outpatient Rehabilitation Requirements

If you do not need round-the-clock care, Medicare Part B covers outpatient physical, occupational, or speech therapy at a clinic, doctor's office, or at home (if you are homebound) without an arbitrary yearly dollar cap, as long as it remains medically necessary.

What is the 21 day rule for Medicare?

The "21-day rule" for Medicare typically refers to the cost-sharing shift in a skilled nursing facility (SNF), where Medicare covers 100% of approved costs for the first 20 days, but requires a daily coinsurance payment starting on day 21.

Skilled Nursing Facility Coverage Breakdown

  • Days 1–20: Medicare pays 100% of the approved costs (after you meet your Part A deductible).
  • Days 21–100: You must pay a daily coinsurance amount, which is $217 per day for 2026.
  • Day 101 and beyond: Medicare coverage ends completely, and you are responsible for 100% of the costs.

(Note: In some home health care contexts, a separate "21-day rule" guideline describes intermittent care limits where services are expected to last under 21 days, but the primary financial and coverage definition relates to the transition from day 20 to day 21 in a rehab or skilled nursing setting.)
