Discharge from the hospital rarely means recovery is done. After a hip replacement, a stroke or a bad fall, many people need extra time in a skilled nursing facility for rehab before they go home. This is the process patients go through every day at places like St. Ann’s Rehab & Transitional Care Center. Most of the confusion is not about the therapy itself. It is about a few Medicare rules that rarely get explained until you are already living through them.
The three-day rule, and one thing to watch for
To qualify for rehab coverage under Original Medicare, you generally need to have been admitted to the hospital as an inpatient for at least three days in a row, and your doctor has to say you need daily skilled care. Here is the part that surprises people: if the hospital classifies your stay as “observation” instead of “inpatient,” those nights do not count, even if you were there overnight for several nights. It is worth asking the hospital directly whether your stay counts as inpatient, since it can change what happens next.
If you have a Medicare Advantage plan, the rule works differently. Instead of counting days, your plan reviews your medical records and approves the stay ahead of time. Neither approach is better or worse. It just helps to know which one applies to you before you need it.
What Medicare covers, and a common misunderstanding
Once your rehab stay is approved, Medicare typically covers physical, occupational and speech therapy, skilled nursing care, meals and help with daily activities and any medications you need during your stay.
A lot of people believe you have to keep improving to keep your coverage, and that it ends the moment progress slows down. That is not quite true. Medicare’s own guidance says coverage is based on whether you still need skilled care, not on whether that care is making you better. Someone who has stopped improving but still needs a nurse or therapist to keep from getting worse can still qualify. What actually ends coverage is no longer needing that level of care, which is part of why your care team documents your progress so closely every day.
What it costs, and how the timing works
Medicare coverage for rehab runs on something called a benefit period. It starts the day you’re admitted to the hospital and doesn’t end until you’ve gone 60 days in a row without needing hospital or skilled nursing care again. In 2026, within that period: the first 20 days of a covered rehab stay cost you nothing extra once your hospital deductible is paid, days 21 through 100 cost $217 per day, and Medicare does not cover skilled nursing rehab past 100 days. If you end up back in the hospital before that 60-day break is up, you’re still in the same benefit period. If it happens after, the clock starts over, deductible included.
What to expect during your stay
At a place like St. Ann’s, your care usually starts with a meeting between your doctor, therapists, nurses and a social worker, who build a plan around your goals and what your home situation looks like. Your progress gets checked every day, both because it helps your recovery and because it’s what keeps your coverage active.
How long you’ll stay depends a lot on why you’re there. A joint replacement might mean one to two weeks. Recovering from a stroke or a more complicated surgery usually takes longer, and most care teams can’t give you a firm timeline until they see how your first few days of therapy go.
A couple of other things worth knowing. You have the right to choose which facility you go to for rehab, rather than automatically going wherever the hospital first suggests. Families are usually welcome to join care meetings and learn things like how to safely help with transfers or get the home ready before discharge. And if you need more time than Medicare covers, or your needs change, the social worker on your case can walk you through the options, whether that’s outpatient therapy, home health care, or longer-term care.
None of this makes the move from hospital to rehab effortless, but knowing these rules ahead of time, instead of learning them in the middle of a hospital stay, makes the whole process much easier to manage.
