What is an Inpatient?
You’re an inpatient starting the day you’re formally admitted to the hospital with a doctor’s order. The day before you’re discharged is your last inpatient day.
The decision for inpatient hospital admission is a complex medical decision based on your doctor’s judgment and your need for medically necessary hospital care. An inpatient admission is generally appropriate when you’re expected to need 2 or more midnights of medically necessary hospital care, but your doctor must order such admission and the hospital must formally admit you in order for you to become an inpatient.
