Dermatitis due to substances taken internally
Chapter 12:Diseases of the skin and subcutaneous tissue
ICD-10 L27 is a used to indicate a diagnosis of dermatitis due to substances taken internally.
L27 refers to dermatitis due to substances taken internally, which encompasses a range of skin reactions resulting from systemic exposure to various substances, including medications, food allergens, and toxins. Clinically, patients may present with erythema, pruritus, urticaria, or more severe manifestations such as exfoliative dermatitis. The anatomy involved primarily includes the skin and its appendages, where the immune response to the offending substance leads to inflammation and disruption of the epidermal barrier. Disease progression can vary; some patients may experience acute reactions that resolve upon discontinuation of the offending agent, while others may develop chronic dermatitis requiring ongoing management. Diagnostic considerations include a thorough patient history to identify potential triggers, skin examinations, and possibly patch testing or laboratory evaluations to confirm the diagnosis. It is essential to differentiate L27 from other dermatitis codes, such as allergic contact dermatitis (L23) or atopic dermatitis (L20), to ensure appropriate treatment and management.

L27 covers dermatitis resulting from systemic exposure to substances such as medications (e.g., antibiotics, NSAIDs), food allergens (e.g., nuts, shellfish), and toxins. Conditions may include drug eruptions, food-related dermatitis, and reactions to supplements.
L27 should be used when dermatitis is specifically linked to substances taken internally, as opposed to contact dermatitis (L23) which is due to external exposure. Careful documentation of the patient's history and the specific substance involved is crucial for accurate coding.
Documentation should include a detailed patient history, including any recent medications or dietary changes, clinical findings from skin examinations, and any diagnostic tests performed to identify the causative agent.
