About T62.2X4

T62.2X4 is the ICD-10-CM diagnosis code for toxic effect of other ingested (parts of) plant(s), undetermined. It belongs to category T62 (toxic effect of other noxious substances eaten as food), 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 T62.2X (toxic effect of other ingested (parts of) plant(s)), T62.2X4 is specifically for toxic effect of other ingested (parts of) plant(s), undetermined. Related codes cover accidental (unintentional) (T62.2X1), intentional self-harm (T62.2X2) and assault (T62.2X3).

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.
