Nonbullous erythema multiforme
ICD-10 L51.0 is a billable code used to indicate a diagnosis of nonbullous erythema multiforme.
Nonbullous erythema multiforme is an acute, self-limiting skin condition characterized by the sudden onset of target-like lesions, typically affecting the extremities and mucous membranes. The condition primarily involves the epidermis and dermis, where immune-mediated responses lead to keratinocyte apoptosis and inflammation. Clinically, patients present with symmetrical, erythematous macules and papules that may evolve into target lesions, often accompanied by pruritus or burning sensations. The disease can be triggered by infections, particularly herpes simplex virus, medications, or other environmental factors. Disease progression is generally benign, with spontaneous resolution within weeks; however, recurrent episodes may occur. Diagnostic considerations include a thorough patient history, physical examination, and, when necessary, skin biopsy to rule out other dermatological conditions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Laboratory tests may be conducted to identify underlying infections or triggers.

L51.0 specifically covers nonbullous erythema multiforme, which is characterized by target lesions without the presence of blisters. It is important to differentiate it from bullous forms and other similar dermatological conditions.
L51.0 should be used when the clinical presentation aligns with nonbullous erythema multiforme, particularly when target lesions are present without blistering. It is crucial to assess the patient's history for triggers to ensure accurate coding.
Documentation should include a detailed patient history, physical examination findings, and any relevant laboratory results. Descriptions of the lesions, their distribution, and any associated symptoms are essential for supporting the diagnosis of L51.0.
