About this chapter
ICD-10-CM Chapter X — “Diseases of the respiratory system” — spans every category from J00 through J99. Each category in that range expands into a header code and one or more billable codes with additional specificity (laterality, episode of care, or clinical detail). Open any code’s own page to see its exact position in the hierarchy, its parent and children, and whether it’s billable.
