About T63
T63 is the ICD-10-CM diagnosis code for toxic effect of contact with venomous animals and plants. It belongs to 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T63.0 (venom), T63.1 (reptiles), T63.2 (scorpion), T63.3 (spider), T63.4 (arthropods), T63.5 (fish), T63.6 (animals), T63.7 (plant) and 2 more.
The conditions in its Excludes2 note aren't part of T63, but may be coded alongside it if the patient has both: ingestion of toxic animal or plant (T61.-, T62.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
