About X58

X58 is the ICD-10-CM diagnosis code for exposure to other specified factors. It belongs to block X52-X58 (accidental exposure to other specified factors) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: X58.XXXA (initial encounter), X58.XXXD (subsequent encounter) and X58.XXXS (sequela).

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