Checked out
Checked out is not domain specific language. When talking about medical visits, checked out is an informal term for having a medical evaluation. A check-up is a routine procedure done yearly that is normally called a physical in the medical field. A fall is a fall. There is no other domain specific vocabulary that can change this. Clinic and injuries are all typical domain specific terms that can be applied in medical situations.
