Toxic erythema

This code represents a non-specific inflammatory skin reaction characterized by redness, often accompanied by papules, vesicles, or pustules. It is typically a generalized eruption caused by exposure to toxins, drugs, or other irritants, but not specifically related to the neonatal period.

Assign this code when documentation specifies "toxic erythema" as the diagnosis, particularly when the etiology is attributed to a drug reaction, chemical exposure, or other systemic toxin. Ensure the patient is not a neonate, as that condition has a specific exclusion.

• Differentiate from allergic contact dermatitis (L23.-) or irritant contact dermatitis (L24.-) if a specific external agent is identified and the reaction is localized.
• Always code the underlying cause (e.g., drug, chemical) as an additional diagnosis if known and documented.
• Review documentation carefully to rule out neonatal erythema toxicum, which is an Excludes1 condition.
