Post-Acute Care After Surgery: Nursing Home vs. Rehab vs. Home Recovery

Key Takeaways

  • Skilled nursing facilities (SNFs), inpatient rehabilitation facilities (IRFs), and home health serve different recovery needs after hospital discharge, with distinct Medicare coverage limits and out-of-pocket costs.
  • CMS data shows significant differences in 30-day readmission rates across settings (SNF: 33.1%, IRF: 12.5%, home/self-care: 13.9%), though these reflect patient acuity at discharge, not setting quality alone.
  • Medicare covers up to 100 days of SNF care (with $217/day coinsurance after day 20 in 2026) and unlimited home health visits, but coverage requires a qualifying 3-day hospital stay and skilled care needs.
  • IRFs require patients to tolerate intensive rehabilitation and have qualifying diagnoses; they typically serve patients with higher functional recovery potential.
  • The right setting depends on the person’s functional ability, medical complexity, home support system, and recovery goals—data on readmission and discharge outcomes can inform but not dictate that choice.

The Three Post-Acute Care Settings: How They Differ

When a hospital stay ends, most patients don’t go straight home. They go to a post-acute care setting—a skilled nursing facility, an inpatient rehabilitation facility, or home with a home health agency. These three options differ in intensity, eligibility, and what Medicare will pay for. Understanding those differences is the first step in making sense of what’s ahead.

Skilled Nursing Facilities (SNFs)

A skilled nursing facility—commonly called a nursing home—provides 24-hour care that includes nursing, physical therapy, occupational therapy, and speech therapy after a hospital stay. The key word here is “skilled.” According to CMS, Medicare’s SNF benefit does not cover custodial care alone—help with bathing, dressing, or toileting by itself doesn’t qualify. The services must require the skills of licensed clinical or technical personnel.

For Medicare to cover the stay, the patient must have had a qualifying 3-day inpatient hospital stay before admission, as required under 42 CFR 409.30. Coverage runs up to 100 days per benefit period. Learn more about what triggers and limits that benefit in Medicare Skilled Nursing Benefits After a Hospital Stay.

It’s also worth knowing what SNFs are not: they are not the same as long-term nursing home care. Most long-stay nursing facility residents are on Medicaid, not Medicare. The Medicare SNF benefit is specifically for short-term recovery.

Inpatient Rehabilitation Facilities (IRFs)

An IRF is a hospital-level setting focused on intensive, structured rehabilitation. Patients must be able to tolerate at least 3 hours of therapy per day, 5 days a week. CMS also requires that at least 60% of an IRF’s patients have one of a set of qualifying diagnoses—a rule known as the “60 percent rule” (42 CFR 412.23(b)(2))—covering conditions such as stroke, hip fracture, and major joint replacement.

IRFs collect detailed functional outcome data through the IRF Patient Assessment Instrument (IRF-PAI). As of October 1, 2024, CMS requires completion of the IRF-PAI for all patients, regardless of payer—meaning the outcome data now reflects a broader population than Medicare alone.

Home Health Care

Home health is the least intensive of the three options. A Medicare-certified home health agency sends clinicians—nurses, therapists, aides—to the patient’s home for intermittent visits. To qualify, according to KFF, the patient must be homebound and under physician oversight. There is no day limit on the Medicare home health benefit, but it covers skilled intermittent care only—not 24-hour supervision or ongoing custodial help.

In 2023, 7% of traditional Medicare beneficiaries used home health services, compared to 3% who had a skilled nursing facility stay, according to KFF.

What CMS Data Shows About Readmission and Recovery Rates

One of the clearest ways to compare post-acute care settings is through 30-day readmission rates—how often patients end up back in an acute care hospital within a month of leaving. CMS tracks this measure across settings, and the numbers look very different depending on where a patient goes after discharge.

30-Day Readmission by Setting

According to a CMS report on readmission reduction initiatives, the 30-day hospital readmission rate for patients discharged to a skilled nursing facility was 33.1%. For patients discharged to an inpatient rehabilitation facility, it was 12.5%. For those sent home or to self-care, the rate was 13.9%.

Separately, CMS IRF Compare data reports a national 30-day readmission rate of 13.06% for patients discharged from inpatient rehabilitation facilities—meaning patients who completed their IRF stay and were then readmitted to an acute hospital within 30 days. For the most current facility-level figures, CMS publishes this data on Medicare.gov Care Compare.

What These Numbers Really Mean

The SNF readmission rate of 33.1% is striking, but it needs context. Patients discharged to SNFs are typically older, sicker, and more functionally limited than those cleared for home or IRF placement. The number reflects who goes to a SNF as much as what happens there. A 2019 study published in JAMA Internal Medicine (pubmed.ncbi.nlm.nih.gov), drawing on 17.2 million Medicare hospitalizations from 2010 to 2016, found that discharge to home health was associated with a 5.6-percentage-point higher 30-day readmission rate compared to SNF discharge—but noted no significant difference in 30-day mortality between the two groups. That study is now outside the standard freshness window for academic research and should be read as historical context rather than a current benchmark.

The point is not that one setting is safer than another in isolation. It is that patient acuity, support systems, and medical complexity drive both the placement decision and the readmission risk.

Discharge-to-Community Rates

Readmission is one lens. Another is whether patients eventually return home at all. CMS tracks discharge-to-community rates for both SNFs (through the SNF Value-Based Purchasing program) and IRFs (through the IRF Quality Reporting Program). Aggregate national averages by setting were not available from whitelisted public sources at the time of publication; families can compare individual facilities on Medicare.gov Care Compare using this metric. For more context on how these outcome measures are defined and reported, see Why Post-Acute Rehab Outcomes Matter.

Medicare Coverage: What Each Setting Costs You

Medicare’s rules for each post-acute setting are distinct. The cost differences are real, and the coverage limits matter most when a stay extends beyond a few weeks.

Skilled Nursing Facility Coverage and Costs

Medicare Part A covers up to 100 days of SNF care per benefit period after a qualifying 3-day inpatient hospital stay, according to the official Medicare SNF coverage booklet. Days 1 through 20 cost the patient nothing. Starting on day 21, CMS sets the daily coinsurance at $217.00 in 2026 (up from $209.50 in 2025). After day 100, Medicare pays nothing.

Medigap supplemental insurance may cover all or part of the days 21–100 coinsurance, according to the Medicare SNF booklet. For people who are dually eligible for Medicare and Medicaid, Medicaid typically covers the copayment as well.

Inpatient Rehabilitation Facility Coverage

IRF stays fall under Medicare Part A as well, using the same benefit period structure as hospital care. The Part A deductible of $1,736 applies in 2026, per CMS. IRF payment rates to facilities are adjusted under the IRF Prospective Payment System (42 CFR Part 412, Subpart P). For the patient, the out-of-pocket exposure follows Part A hospital cost-sharing rules rather than the SNF coinsurance schedule. CMS did not publish separate IRF-specific coinsurance amounts on whitelisted public pages at the time of writing; families should confirm their specific cost-sharing with Medicare or a benefits counselor before admission.

Home Health Coverage and Limits

Medicare covers home health visits with no day limit and no patient coinsurance for the visits themselves, provided the patient meets homebound status and has physician-certified skilled care needs. As KFF explains, the benefit is for skilled intermittent care—not ongoing or around-the-clock support. Home health agencies operate under the Home Health Prospective Payment System (42 CFR Part 484), using the Patient-Driven Groupings Model since January 2020. CMS estimated aggregate Medicare payments to home health agencies increased 0.5% (about $85 million) in CY 2025 compared to CY 2024.

The 100-Day SNF Limit

Medicare’s SNF benefit is designed for short-term recovery, not extended care. According to KFF, Medicare does not cover long-term nursing facility care, custodial care, or SNF stays that don’t follow a qualifying hospital admission. Once the 100-day benefit period ends—or once a patient no longer needs skilled care—Medicare stops paying.

When Medicaid or Savings Take Over

For people who need ongoing nursing facility care beyond what Medicare covers, Medicaid is typically the primary payer. KFF reports that as of July 2024, more than 60% of the 1.2 million people living in nursing facilities had Medicaid as their primary payer, and Medicaid covered 44% of all long-term institutional care costs in 2023. Medicaid eligibility is income- and asset-based and varies by state.

Long-Term Care Cost Reality

For those who don’t qualify for Medicaid and exhaust Medicare coverage, the costs are substantial. According to KFF, 2024 median annual costs in the U.S. were $127,750 for a private room in a nursing home, $77,792 for a home health aide, and $70,800 for an assisted living facility. These are national medians; state-by-state variation is significant.

How to Think About Your Situation

Data on readmission rates and coverage rules can clarify what each setting involves. It can’t make the decision for a family. The right post-acute setting depends on the patient’s condition, functional status, home environment, and what Medicare or insurance will cover.

Key Questions to Ask Your Doctor

Before leaving the hospital, families often find it useful to work through a short set of questions with the care team:

  • Does this patient meet the functional and medical criteria for an IRF stay?
  • Is skilled nursing or therapy needed daily, or would intermittent home visits be sufficient?
  • Is the home environment safe for discharge, and is there someone available to help?
  • What level of functional recovery is realistic, and over what timeframe?
  • Has the patient had a qualifying 3-day inpatient hospital stay for SNF Medicare eligibility purposes?

The A Discharge Planning Checklist for Families provides a structured way to track these questions before discharge.

When Data Supports Each Option

The IRF Quality Reporting Program now collects standardized functional outcome data through the Discharge Function Score measure, adopted in the FY 2024 IRF PPS final rule with data collection starting October 1, 2023. This measure tracks the percentage of IRF patients who meet or exceed an expected discharge function score based on self-care and mobility items from the IRF-PAI. Facility-level results are publicly available on Medicare.gov Care Compare.

For SNFs, the SNF Value-Based Purchasing program similarly tracks 30-day readmission as a quality metric. The IMPACT Act of 2014 (Section 1899B of the Social Security Act) requires all post-acute settings—SNFs, IRFs, long-term care hospitals, and home health agencies—to collect and submit standardized patient assessment data to CMS, making it possible to compare quality across settings using a common framework.

Families who want to look at facility-specific outcome data before choosing a provider can start at Comparing Rehab Options After Hospital Discharge. For managing the transition between providers once a setting is chosen, Coordinating Care Among Multiple Providers covers what that process typically looks like.
