About L30

L30 is the ICD-10-CM diagnosis code for other and unspecified dermatitis. 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: L30.0 (dermatitis), L30.1 ([pompholyx]), L30.2 (autosensitization), L30.3 (dermatitis), L30.4 (intertrigo), L30.5 (alba), L30.8 (dermatitis) and L30.9 (unspecified).

The conditions in its Excludes2 note aren't part of L30, but may be coded alongside it if the patient has both: contact dermatitis (L23-L25), dry skin dermatitis (L85.3), small plaque parapsoriasis (L41.3) and stasis dermatitis (I87.2).

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