Subacute cutaneous lupus erythematosus

This code identifies a specific form of lupus erythematosus characterized by non-scarring, photosensitive skin lesions, typically annular or psoriasiform, without significant systemic involvement. It represents a distinct clinical subtype of cutaneous lupus, often intermediate between discoid lupus and systemic lupus erythematosus.

Apply this code when documentation clearly indicates a diagnosis of subacute cutaneous lupus erythematosus (SCLE). This diagnosis is typically made based on characteristic skin lesions, often confirmed by biopsy showing interface dermatitis, and serological findings such as positive anti-Ro/SSA antibodies.

• Differentiate from discoid lupus erythematosus (L93.0) and systemic lupus erythematosus (M32.-) based on clinical presentation and systemic involvement.
• Ensure documentation specifies "subacute cutaneous" to avoid confusion with other forms of cutaneous lupus.
• Code any associated systemic manifestations of lupus separately, if present and documented.
