Irritant contact dermatitis due to drugs in contact with skin
ICD-10 L24.4 is a billable code used to indicate a diagnosis of irritant contact dermatitis due to drugs in contact with skin.
Irritant contact dermatitis due to drugs in contact with skin is a localized inflammatory skin condition that arises when the skin comes into direct contact with a chemical agent, particularly drugs. Clinically, it presents with symptoms such as erythema, swelling, vesiculation, and pruritus, which may develop within hours to days after exposure. The anatomy involved primarily includes the epidermis and dermis, where the inflammatory response occurs. Disease progression can vary; mild cases may resolve with avoidance of the irritant, while severe cases can lead to chronic dermatitis if exposure continues. Diagnostic considerations include a thorough patient history to identify potential irritants, physical examination findings, and, if necessary, patch testing to confirm the diagnosis. It is crucial to differentiate irritant contact dermatitis from allergic contact dermatitis, as the management strategies differ significantly. Accurate diagnosis is essential for effective treatment and prevention of recurrence.

L24.4 specifically covers irritant contact dermatitis caused by drugs that come into direct contact with the skin, including topical medications, antiseptics, and other chemical agents. It does not cover allergic reactions or dermatitis caused by non-drug irritants.
L24.4 should be used when the dermatitis is specifically due to drug exposure, as opposed to L24.0, which is a general code for irritant contact dermatitis. Accurate identification of the irritant is essential for proper coding.
Documentation should include a detailed patient history of drug exposure, clinical findings such as the location and appearance of the dermatitis, and any diagnostic tests performed, such as patch testing, to confirm the irritant.
