Seborrheic infantile dermatitis
ICD-10 L21.1 is a billable code used to indicate a diagnosis of seborrheic infantile dermatitis.
Seborrheic infantile dermatitis, commonly referred to as cradle cap, is a benign skin condition that primarily affects infants, typically appearing within the first few months of life. Clinically, it presents as yellowish, greasy scales or crusts on the scalp, but it can also affect other areas such as the face, neck, and behind the ears. The condition is thought to be related to the overproduction of sebum and the presence of Malassezia yeast, which thrives in oily environments. The skin involved is primarily the epidermis, where inflammation occurs due to the accumulation of sebum and skin cells. Disease progression is generally self-limiting, with most cases resolving by the age of 12 months. Diagnostic considerations include a thorough clinical examination and, if necessary, ruling out other dermatological conditions such as atopic dermatitis or psoriasis. Treatment is often conservative, involving gentle cleansing and the use of emollients or medicated shampoos, and is rarely required unless the condition becomes severe or secondary infections occur.

L21.1 specifically covers seborrheic infantile dermatitis, characterized by yellowish, greasy scales on the scalp and other areas in infants. It is distinct from other dermatitis types such as atopic dermatitis (L20) and seborrheic dermatitis in older children and adults (L21.0).
L21.1 should be used when diagnosing seborrheic dermatitis specifically in infants under 1 year of age. If the patient is older or if the dermatitis presents differently, other codes such as L21.0 or L20 may be more appropriate.
Documentation should include a clear description of the clinical presentation, duration of symptoms, and any treatments attempted. Photographic evidence may also be beneficial to support the diagnosis and differentiate from other skin conditions.
