In simple words: A person is considered unsheltered when they are living outside or in a place not designed for people to live, such as streets, cars, or abandoned buildings.

Unsheltered homelessness is characterized by living in places not meant for human habitation, such as on the streets, in abandoned buildings, in vehicles, or in parks. This condition signifies a lack of access to safe and consistent shelter.

Example 1: A 35-year-old male presents to the emergency department with a foot infection. He reports living under a bridge for the past six months.Diagnosis: Z59.02 (Unsheltered homelessness), L08.112 (Cellulitis of right foot, non-purulent)., A 28-year-old female is seen at a free clinic for a cough and fever.
