About T56.892

T56.892 is the ICD-10-CM diagnosis code for toxic effect of other metals, intentional self-harm. It belongs to category T56 (toxic effect of metals), 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 T56.89 (toxic effects of other metals), T56.892 is specifically for toxic effect of other metals, intentional self-harm. Related codes cover accidental (unintentional) (T56.891), assault (T56.893) and undetermined (T56.894).

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.

Use an additional code to identify any retained metal foreign body, if applicable (Z18.0-, T18.1-).

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