About T62

T62 is the ICD-10-CM diagnosis code for toxic effect of other noxious substances eaten as food. 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T62.0 (mushrooms), T62.1 (berries), T62.2 (plant(s)), T62.8 (food) and T62.9 (food).

Don't report T62 together with the conditions in its Excludes1 note: anaphylactic shock (reaction) due to adverse food reaction (T78.0-), bacterial food borne intoxications (A05.-), dermatitis (L23.6, L25.4, L27.2), food protein-induced enterocolitis syndrome (K52.21) and 6 more.

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