About T63.19

T63.19 is the ICD-10-CM diagnosis code for toxic effect of venom of other reptiles. It belongs to category T63 (toxic effect of contact with venomous animals and plants), 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 4 subcodes must be used instead.

Within T63.1, choose T63.19 (other reptiles) only when documentation doesn't support a more specific option: gila monster (T63.11) and other venomous lizard (T63.12).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
