Other seborrheic dermatitis

This code represents forms of seborrheic dermatitis that do not fit the more specific categories of cradle cap or seborrheic infantile dermatitis. It encompasses inflammatory skin conditions characterized by greasy, yellowish scales and erythema, typically affecting areas rich in sebaceous glands such as the scalp, face (eyebrows, nasolabial folds), and chest.

Use this code when documentation specifies seborrheic dermatitis that is not explicitly identified as infantile (cradle cap) or other specified types. This includes adult-onset seborrheic dermatitis affecting various body sites beyond infancy. Supporting documentation should clearly state "seborrheic dermatitis" without further specification or indicate a location not covered by more specific codes.

• Ensure the documentation does not specify "cradle cap" (L21.0) or "seborrheic infantile dermatitis" (L21.1) before assigning this code.
• If a specific body site is documented, verify if a more precise code exists within the L21 category before defaulting to "other."
• Code any associated complications, such as secondary infection, separately.
