Inpatient physical rehabilitation is often an essential part of recovery following surgery, a stroke, a major injury, or another serious medical event. Medicare provides coverage for inpatient rehab under specific conditions, and knowing the rules will help you prepare for what lies ahead.
What Does Inpatient Rehabilitation Involve?
Inpatient rehabilitation is provided in a specialized setting, either a standalone Inpatient Rehabilitation Facility (IRF) or a dedicated rehabilitation unit within a hospital. Patients typically receive intensive therapy, including:
- Physical therapy
- Occupational therapy
- Speech-language pathology
- Nursing care
- Medical oversight
Inpatient rehab is distinct from outpatient therapy because of its intensity. Patients generally take part in at least three hours of therapy per day, five days per week, or a minimum of 15 hours of therapy over a seven-day period.
How Medicare Part A Covers Inpatient Rehab
Medicare Part A pays for inpatient rehabilitation when the following criteria are satisfied:
- You had a qualifying hospital stay of at least three consecutive inpatient days
- You were admitted to the rehab facility within 30 days of your hospital discharge
- You require intensive, multidisciplinary rehabilitation that can only be delivered in an inpatient setting
- Your physician certifies that you need skilled rehabilitation services
- You are demonstrating measurable progress toward your recovery objectives
How Long Will Medicare Pay for Inpatient Rehab?
Medicare Part A provides coverage for up to 60 days of inpatient rehabilitation per benefit period. The cost breakdown is:
| Days | Your Cost (2026) | |---|---| | Days 1-60 | $1,736 deductible (per benefit period), then $0 | | Days 61-90 | $434 per day coinsurance | | Days 91+ | $868 per day (using lifetime reserve days) |
The majority of inpatient rehab stays last between two and three weeks, though duration depends on the severity of your condition and the speed of your recovery.
Skilled Nursing Facility as an Alternative
If you do not qualify for an IRF but still require rehabilitation services, Medicare may cover care in a Skilled Nursing Facility (SNF). SNF coverage includes:
- Up to 100 days per benefit period
- Days 1-20: $0 after the Part A deductible
- Days 21-100: $217 per day coinsurance (2026)
- A qualifying three-day hospital stay is required
Outpatient Rehabilitation After Discharge
Once you leave inpatient rehab, you may continue your recovery through outpatient physical therapy covered by Medicare Part B. Part B covers:
- Physical therapy
- Occupational therapy
- Speech-language pathology services
You are responsible for 20% of the Medicare-approved amount after satisfying the annual Part B deductible. Annual therapy caps have been eliminated, but services may need prior authorization if costs surpass certain thresholds.
Medicare Advantage and Inpatient Rehab
Medicare Advantage plans are required to cover the same inpatient rehab services as Original Medicare, but the details may differ:
- You may be required to use in-network facilities
- Prior authorization may be necessary
- Cost-sharing amounts may be different from those under Original Medicare
Review your plan's Evidence of Coverage for full details on rehabilitation benefits and any applicable restrictions.
Advice for Managing Inpatient Rehab Coverage
- Confirm your hospital admission status - Make sure you were admitted as an inpatient (not placed under observation) to satisfy the three-day requirement
- Request documentation of medical necessity - Ensure your care team records why inpatient-level rehabilitation is required
- Know your appeal rights - If Medicare denies coverage, you have the right to file an appeal
- Prepare for discharge - Coordinate with your rehab team to set up outpatient therapy and home support before you are released
