The short version
Home health delivers clinical care in the home: a nurse changing a wound dressing, a physical therapist rebuilding strength after a fall, a speech therapist working on swallowing after a stroke. A doctor orders it, it is intermittent rather than continuous, and Medicare pays when the eligibility conditions are met.
Home care delivers help with daily living: bathing, dressing, meal preparation, laundry, errands, medication reminders, companionship, and supervision. No doctor's order is required, it can be scheduled for as many hours as you can pay for, and Medicare does not cover it on its own.
One is a medical benefit. The other is a service you buy. That single difference drives almost everything else.
Who pays
Medicare's home health benefit covers skilled nursing, physical therapy, occupational therapy, speech-language pathology, medical social services, and a home health aide — but the aide only alongside a qualifying skilled service. There is generally no cost-sharing for the covered visits themselves.
Home care is typically paid out of pocket, by long-term care insurance, or in some circumstances through Medicaid waiver programs or Veterans benefits. Rates are hourly and vary widely by region and by whether care is scheduled in short visits or live-in shifts.
This is where most of the confusion becomes expensive. A family told that Medicare covers home health sometimes assumes it will also pay for someone to be at the house each afternoon. It will not, unless a qualifying skilled service is in place and the aide visits are part of that plan.
Who qualifies
For Medicare home health you generally must be homebound — leaving home requires a considerable and taxing effort — and you must need intermittent skilled care. A physician must certify both, and the agency must be Medicare-certified.
For home care there is no eligibility test. If you can pay, you can arrange it. That accessibility is exactly why it is often the right answer for the long, non-clinical stretches of caregiving that Medicare was never designed to cover.
What you can look up before choosing
This is the difference families are least aware of, and it matters most when comparing providers.
Medicare-certified home health agencies are federally certified and publicly measured. CMS publishes a quality-of-patient-care star rating, patient-outcome measures, the service lines each agency offers, and ownership type. You can compare agencies on a public record before you call one.
Home care agencies are licensed by individual states, with requirements that vary considerably. There is no federal star rating, no national quality dataset, and no CMS record to compare. Assessment relies on state licensing status, references, and your own screening.
So if you are choosing between two Medicare-certified home health agencies, there is public evidence to work from. If you are choosing between two home care agencies, there generally is not — and any site presenting a national 'rating' for them is using its own methodology rather than a federal one.
When you need both
A common pattern after a hospital discharge: Medicare home health provides a nurse and a physical therapist for a few weeks while recovery is active, and the family separately arranges home care for the daily hours nobody is covering.
When the skilled need ends, Medicare home health ends with it — including the aide visits attached to it. The home care arrangement continues, because it was never part of the Medicare benefit. Planning for that handover in advance avoids a gap at exactly the point the household is most tired.
How to act on the distinction
Start by naming the need precisely. If it involves a clinical task — wound care, injections, therapy, monitoring an unstable condition — that is home health, and the route is a conversation with the physician who can order it.
If it involves hours of presence, personal care, and household support, that is home care, and the route is a private arrangement.
If it is both, run them in parallel rather than sequentially, and confirm which provider is responsible for what. Where the need is home health, you can compare Medicare-certified agencies on their CMS record — star rating, reported measures, services offered, and ownership — before choosing.
