About L20.8

L20.8 is the ICD-10-CM diagnosis code for other atopic dermatitis. It belongs to category L20 (atopic dermatitis), 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 5 subcodes must be used instead.

Within L20, choose L20.8 (Other atopic dermatitis) only when documentation doesn't support a more specific option: Besnier's prurigo (L20.0) and unspecified (L20.9).

To report this condition, pick the subcode that matches the documentation: L20.81 (neurodermatitis), L20.82 (eczema), L20.83 (eczema), L20.84 (eczema) and L20.89 (dermatitis).

The conditions in its Excludes2 note aren't part of L20.8, but may be coded alongside it if the patient has both: circumscribed neurodermatitis (L28.0).

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