About T58.13
T58.13 is the ICD-10-CM diagnosis code for toxic effect of carbon monoxide from utility gas, assault. It belongs to category T58 (toxic effect of carbon monoxide), block T51-T65 (toxic effects of substances chiefly nonmedicinal as to source) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within T58.1 (toxic effect of carbon monoxide from utility gas), T58.13 is specifically for toxic effect of carbon monoxide from utility gas, assault. Related codes cover accidental (unintentional) (T58.11), intentional self-harm (T58.12) and undetermined (T58.14).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
