Skilled nursing care, for Medicare purposes, is any nursing or therapy service that can only be safely and effectively performed by, or under the supervision of, a licensed professional such as a registered nurse or physical therapist. The key distinction is between care that requires professional clinical judgment and care that a non-medical person could reasonably provide. Medicare Part A covers up to 100 days of skilled nursing facility (SNF) care per benefit period, with the first 20 days at no cost to you and days 21 through 100 requiring a daily coinsurance of $209.50 in 2025.
What Makes Care “Skilled”
The core test is straightforward: does the service require the training and judgment of a healthcare professional? If a family member or home aide could safely do it, Medicare considers it custodial care and won’t cover it. If it requires a nurse, therapist, or other licensed professional, it qualifies as skilled.
Skilled nursing services include intravenous injections and medication management, wound care for complex or non-healing wounds, tube feedings, catheter care, and monitoring unstable medical conditions that need regular assessment by a nurse. Skilled therapy services include physical therapy, occupational therapy, and speech-language pathology provided by licensed therapists. Even something like observing and evaluating your condition counts as skilled care when it requires clinical expertise to interpret what’s happening and adjust your treatment plan.
The services must also be “reasonable and necessary” for your specific condition. That means the type of care, how often you receive it, and how long it continues all need to match what your medical situation actually requires.
You Don’t Have to Be Getting Better
One of the most misunderstood aspects of Medicare’s skilled nursing coverage is the improvement requirement, or rather, the lack of one. For years, claims were routinely denied when a patient stopped showing measurable improvement. A landmark legal settlement (known as the Jimmo settlement) clarified that Medicare cannot deny coverage simply because you aren’t expected to get better.
If skilled services are needed to maintain your current condition, or to prevent or slow further decline, Medicare covers them. The requirement is that a qualified professional’s judgment, knowledge, and skills are necessary for the maintenance care to be delivered safely and effectively. So if you need ongoing physical therapy to keep your mobility from deteriorating after a stroke, that qualifies, even if full recovery isn’t realistic. All other coverage criteria still apply, but the absence of improvement potential alone is not a valid reason for denial.
Qualifying for SNF Coverage
Before Medicare will pay for a skilled nursing facility stay, you typically need a qualifying inpatient hospital stay of at least three consecutive days (not counting the discharge day). Observation status does not count as inpatient, which catches many people off guard. You can be physically inside a hospital for several days and still not meet this requirement if you were classified as under observation rather than formally admitted.
Beyond the hospital stay, you must need skilled care on a daily basis. The condition being treated generally needs to be related to your hospital stay, though it doesn’t have to be the exact same diagnosis. Your doctor must order the SNF care, and the facility itself must be Medicare-certified.
What Medicare Pays and for How Long
Each benefit period gives you up to 100 days of SNF coverage. The first 20 days are fully covered by Medicare with no out-of-pocket cost beyond your Part A deductible. Starting on day 21, you pay a daily coinsurance of $209.50 (the 2025 rate, up from $204.00 in 2024). After day 100, Medicare stops covering SNF care entirely, and you’re responsible for the full cost.
A benefit period begins the day you’re admitted as an inpatient to a hospital and ends when you’ve gone 60 consecutive days without receiving inpatient hospital or skilled nursing care. Once that 60-day break occurs, your benefit period resets. If you’re hospitalized again and meet the qualifying stay requirement, a new 100-day SNF benefit becomes available.
What Doesn’t Qualify
Custodial care is the big category Medicare excludes. This covers help with daily activities like bathing, dressing, eating, and moving around, the type of assistance most people picture when they think of nursing home care. If these are the only services you need, Medicare won’t cover the stay, regardless of where you receive them.
Long-term residential care in a nursing home, even a Medicare-certified one, is not covered once your need for daily skilled services ends. Many people transition from Medicare-covered skilled care to private-pay or Medicaid-funded custodial care within the same facility. The shift happens when your clinical team determines that your condition no longer requires the involvement of skilled professionals on a daily basis.
Common Situations That Qualify
- Post-surgical recovery: After a hip or knee replacement, you may need daily physical therapy and wound monitoring that requires professional oversight.
- Stroke rehabilitation: Physical, occupational, and speech therapy often need to be delivered daily by licensed therapists.
- Complex wound care: Surgical wounds, pressure ulcers, or diabetic wounds that require sterile technique and clinical assessment.
- IV medications or injections: Antibiotics, pain management, or other drugs that must be administered by a nurse.
- Chronic condition management: Conditions like COPD or heart failure that become unstable and need daily skilled monitoring and adjustment.
In each of these cases, the defining factor is the same: the care requires professional clinical skills, it’s needed on a daily basis, and it’s reasonable and necessary for your specific medical situation.
