Care Settings
Inpatient
Quick answer
Inpatient care means you have been formally admitted to the hospital with a doctor's order. Inpatient services are covered under Part A.
Plain-English definition
Being 'in the hospital' isn't the same as being admitted — observation status is technically outpatient.
Why it matters
Inpatient vs observation affects your costs and eligibility for SNF care.
A simple example
You're admitted for pneumonia with a doctor's order — that's inpatient.

Outpatient care is any service you receive without being formally admitted to a hospital — doctor visits, day surgery, imaging, ER visits. It's covered under Part B.
Observation Status
Observation is an outpatient designation used while doctors decide whether to admit you. Even overnight observation is outpatient, which changes your costs and can affect eligibility for skilled nursing coverage afterward.
