About this chapter
ICD-10-CM Chapter XIX — “Injury, poisoning and certain other consequences of external causes” — spans every category from S00 through T88. 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.
This is chapter 19of the 22 chapters in the ICD-10-CM code set. Chapters are arranged by body system or type of condition, and a code’s first letter and two digits (its 3-character category) decide which chapter it falls in: anything from S00 to T88 is filed here.
