About L28

L28 is the ICD-10-CM diagnosis code for lichen simplex chronicus and prurigo. It belongs to block L20-L30 (dermatitis and eczema) and chapter 12 (diseases of the skin and subcutaneous tissue). 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: L28.0 (chronicus), L28.1 (nodularis) and L28.2 (prurigo).

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