What is the 60% rule in rehab?

The 60% rule is a Centers for Medicare & Medicaid Services (CMS) regulation requiring that at least 60% of the patients admitted to an Inpatient Rehabilitation Facility (IRF) must have a primary diagnosis or comorbidity requiring intensive rehabilitation for one of 13 specific medical conditions.

Overview of the Rule

• Purpose: Ensures IRFs focus on patients who genuinely need intensive, interdisciplinary medical rehabilitation rather than general nursing care.
• Consequence of Non-Compliance: Facilities that fail to meet the 60% threshold lose their IRF payment classification and risk being reclassified as standard acute care hospitals, which receive lower reimbursement rates for those services.
• Origin: Originally known as the 75% rule, the threshold was adjusted to 60% by Congress under the Medicare, Medicaid, and SCHIP Extension Act of 2007.

The 13 Qualifying Conditions (CMS-13)

To count toward the 60% threshold, a patient must be treated for at least one of these recognized diagnoses:

• Stroke
• Spinal cord injury
• Congenital deformity
• Amputation
• Major multiple trauma
• Hip fracture
• Brain injury (traumatic or non-traumatic)
• Neurological disorders (such as Multiple Sclerosis or Parkinson's disease)
• Burns
• Active, polyarticular, or systemic vasculidities
• Severe osteoarthritis (if involving multiple joints or post-arthroplasty under specific clinical criteria)
• Knee or hip joint replacement (under specific high-complexity criteria, such as bilateral replacements or severe complications)

Key Requirements for IRF Patients

Patients admitted under the rule must also meet operational and clinical criteria, including:

• Intensive Therapy: Typically require at least 3 hours of therapy per day (physical, occupational, or speech therapy) for 5 days a week, or 15 hours over a 7-day period.
• Physician Supervision: Close, frequent face-to-face supervision by a rehabilitation physician (at least 3 times a week).
• Interdisciplinary Care Team: Coordinated care involving a physician, rehabilitation nurse, and multiple therapy disciplines.

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.

The term 60-day Medicare rule usually refers to one of two completely different policies, depending on whether you are a healthcare provider or a patient.

1. The 60-Day Overpayment Rule (For Healthcare Providers)

For doctors, hospitals, and medical suppliers, the 60-day rule requires you to report and return any accidental overpayment from Medicare within 60 days of identifying it.

• The Origin: Established by the Affordable Care Act (ACA).
• When the Clock Starts: The 60-day countdown begins the moment a provider "knows or should have known" about an overpayment through reasonable checks.
• Investigation Pause: Rules allow a suspension of up to 180 additional days to finish a good-faith investigation before the final 60-day return clock runs out (totaling 240 days max).
• The Penalty: Keeping an overpayment past the deadline breaks the False Claims Act, leading to severe fines, legal trouble, or exclusion from Medicare.

2. The 60-Day Benefit Period Rule (For Medicare Patients)

For people with Original Medicare Part A, the 60-day rule measures how long you stay out of a hospital or skilled nursing facility before your "benefit period" resets.

• How a Benefit Period Works: A benefit period starts the day you are admitted as an inpatient.
• When It Ends: The period ends only when you have gone 60 days in a row without receiving any inpatient hospital care or skilled nursing care.
• Why It Matters: If you go back into the hospital after being out for 60 straight days, a brand-new benefit period begins. This means you must pay the Part A hospital deductible again, even if you are being treated for the exact same health issue. You can check official details on the Medicare Skilled Nursing Facility Coverage page.

The Two-Midnight Rule is a Medicare payment policy that states a hospital stay is generally payable as an inpatient admission under Medicare Part A if the admitting doctor expects the patient to require care spanning at least two midnights.

How the Rule Works

• The Benchmark: If a physician formally admits a patient and documents a reasonable expectation that the medically necessary stay will cross two midnights, Medicare Part A will typically cover the inpatient services.
• Observation Status: Stays that are expected to last for less than two midnights are generally classified as outpatient observation services, which are billed under Medicare Part B.
• The Timeframe Starts: The clock for the two-midnight count begins when the patient officially starts receiving services after arriving at the hospital, excluding standard waiting room and routine triage times.

Key Exceptions

A stay can still qualify for inpatient payment even if it does not cross two midnights under specific circumstances:

• Inpatient-Only List: Procedures explicitly designated by the Centers for Medicare & Medicaid Services (CMS) as "inpatient-only" qualify for Part A payment regardless of how long the patient stays.
• Case-by-Case Exceptions: If a physician uses professional judgment to document why an intensive inpatient level of care is medically necessary despite an unexpected short stay.
• Unusual Circumstances: Events such as the patient's death, an unexpected transfer to another facility, or rapid clinical improvement that cuts a planned two-midnight stay short.

The 3-hour rule for inpatient rehab is a Centers for Medicare & Medicaid Services (CMS) guideline requiring patients in an Inpatient Rehabilitation Facility (IRF) to participate in at least 3 hours of therapy per day, 5 days a week.

Key Details of the Rule

• Daily Intensity: Patients must be able to tolerate and actively engage in 3 hours of therapy per day, or at least 15 hours total over a 7-consecutive-day period.
• Eligible Therapies: Qualifying therapy types include physical therapy (PT), occupational therapy (OT), speech-language pathology, and prosthetics or orthotics. At least one discipline must be PT or OT.
• Admission Requirement: To qualify for admission into an IRF, a doctor must reasonably expect that the patient has the physical and cognitive stamina to benefit from this intensive level of care.
• Clinical Flexibility: CMS guidelines state that reviewers should look at clinical need rather than making automatic denials if a patient falls slightly short of the 3-hour threshold due to medical necessity, fatigue, or acute changes in condition.
