About T52.894

T52.894 is the ICD-10-CM diagnosis code for toxic effect of other organic solvents, undetermined. It belongs to category T52 (toxic effect of organic solvents), 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 T52.89 (toxic effects of other organic solvents), T52.894 is specifically for toxic effect of other organic solvents, undetermined. Related codes cover accidental (unintentional) (T52.891), intentional self-harm (T52.892) and assault (T52.893).

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.
