About the X02 Code Range
These codes describe exposure to a controlled fire in a building or structure, including smoke, flames and injuries caused by the burning structure.
X02.0 covers flames, while X02.1 covers smoke. Other subdivisions distinguish a building collapse, a fall, an object hitting someone, and a jump from the burning structure. X02.8 covers other exposure to a controlled fire in a building or structure.
The detailed codes end in A for an initial encounter, D for a subsequent encounter, or S for a sequela.
