Photocontact dermatitis [berloque dermatitis]
ICD-10 L56.2 is a billable code used to indicate a diagnosis of photocontact dermatitis [berloque dermatitis].
Photocontact dermatitis, commonly referred to as berloque dermatitis, is a type of allergic contact dermatitis that occurs when the skin reacts to certain substances that become activated by sunlight. Clinically, it presents as erythematous, pruritic patches that may develop into vesicles or bullae, typically in areas exposed to sunlight. The condition is often associated with the use of certain perfumes, essential oils, or topical medications that contain photosensitizing agents. The anatomy involved primarily includes the epidermis and dermis, where the immune response to the allergen occurs. Disease progression can vary; while some patients may experience mild symptoms that resolve with avoidance of the triggering agent, others may develop chronic dermatitis if exposure continues. Diagnostic considerations include a thorough patient history, identification of potential allergens, and sometimes patch testing to confirm the specific sensitizing agent. It is crucial for healthcare providers to recognize the link between the allergen and sun exposure to effectively manage and prevent recurrence of the condition.

L56.2 specifically covers photocontact dermatitis caused by substances that induce a phototoxic reaction when exposed to sunlight. This includes reactions to certain fragrances, topical medications, and other chemicals that are known to cause skin irritation upon UV exposure.
L56.2 should be used when the dermatitis is specifically linked to a photosensitizing agent and sunlight exposure. If the dermatitis is due to non-phototoxic allergens, other codes such as L23 (Allergic contact dermatitis) should be considered.
Documentation should include a detailed patient history indicating exposure to potential allergens, clinical findings of the dermatitis, and any results from patch testing that confirm the diagnosis of photocontact dermatitis.
