About T55

T55 is the ICD-10-CM diagnosis code for toxic effect of soaps and detergents. 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 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T55.0 (soaps) and T55.1 (detergents).

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