About T62.0

T62.0 is the ICD-10-CM diagnosis code for toxic effect of ingested mushrooms. 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 1 subcodes must be used instead.

Within T62 (toxic effect of other noxious substances eaten as food), T62.0 is specifically for toxic effect of ingested mushrooms. Related codes cover ingested berries (T62.1), other ingested (parts of) plant(s) (T62.2), other specified noxious substances eaten as food (T62.8) and unspecified noxious substance eaten as food (T62.9).

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.
