About T60.4

T60.4 is the ICD-10-CM diagnosis code for toxic effect of rodenticides. It belongs to category T60 (toxic effect of pesticides), 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 T60 (toxic effect of pesticides), T60.4 is specifically for toxic effect of rodenticides. Related codes cover organophosphate and carbamate insecticides (T60.0), halogenated insecticides (T60.1), other insecticides (T60.2), herbicides and fungicides (T60.3), other pesticides (T60.8) and unspecified pesticide (T60.9).

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.

Don't report T60.4 together with the conditions in its Excludes1 note: strychnine and its salts (T65.1) and thallium (T56.81-).

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