T63.4Toxic effect of venom of other arthropods

T63.4 is the ICD-10-CM diagnosis code for toxic effect of venom of other arthropods. 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 7 subcodes must be used instead.

Within T63, choose T63.4 (venom of other arthropods) only when documentation doesn't support a more specific option: snake venom (T63.0), venom of other reptiles (T63.1), venom of scorpion (T63.2), venom of spider (T63.3), contact with venomous fish (T63.5), contact with other venomous marine animals (T63.6), contact with venomous plant (T63.7), contact with other venomous animals (T63.8) and 1 more.

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.

Use an additional code, if applicable, for anaphylactic shock (T78.2).

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