Yes that's correct. You have in-patient where patients stay overnight and outpatient where they walk in, get treated, and leave.
I work at a privately owned outpatient orthopedics clinic where we see geriatrics to minors.
I observed at another privately owned outpatient ortho clinic where it was strictly geriatrics.
I observed at an in-patient long term acute care hospital where the population was geriatrics, and I was also able to see neuro patients.
I observed at an outpatient sports pediatrics clinic in a hospital.
So when I specified these in PTCAS, I had an outpatient privately owned clinic (two of them separately), inpatient hospital, and pediatrics setting (even though it was outpatient; it's still peds).
