Other erythema multiforme
ICD-10 L51.8 is a billable code used to indicate a diagnosis of other erythema multiforme.
Erythema multiforme is a hypersensitivity reaction characterized by target-like lesions on the skin and mucous membranes. L51.8 refers specifically to other forms of erythema multiforme that do not fit into the classic categories of minor or major forms. Clinically, patients may present with symmetrical, erythematous macules, papules, and vesicles, often accompanied by pruritus and burning sensations. The lesions typically evolve over several days and can resolve within 2-4 weeks. The condition primarily affects the skin, but mucosal involvement can lead to complications such as erosions and ulcerations. The etiology of erythema multiforme can be multifactorial, including infections (such as herpes simplex virus), medications, and other triggers. Diagnosis is primarily clinical, supported by patient history and physical examination. Laboratory tests may be performed to rule out other conditions, but they are not typically necessary for diagnosis. Understanding the progression and potential triggers is crucial for effective management and prevention of recurrences.

L51.8 encompasses various atypical presentations of erythema multiforme that do not fall under the minor or major classifications. This may include cases triggered by less common medications or infections not typically associated with classic erythema multiforme.
L51.8 should be used when the erythema multiforme presentation does not meet the criteria for L51.1 or L51.2, particularly when the clinical features are atypical or when the etiology is unclear.
Documentation should include a thorough patient history, details of the clinical presentation, any identified triggers, and the results of any relevant laboratory tests that support the diagnosis.
