L20.89
ICD-10-CMThis code signifies a form of atopic dermatitis that does not fit into the more specific categories of infantile, extrinsic, or intrinsic atopic dermatitis. It represents a chronic inflammatory skin condition characterized by pruritus, erythema, and lichenification, often with a relapsing course.
Use this code when the provider's documentation clearly diagnoses atopic dermatitis but does not specify it as infantile, extrinsic, or intrinsic. This is appropriate for adult or pediatric cases where the specific type of atopic dermatitis is not further elaborated or when it presents with atypical features not covered by other codes.
