Staphylococcal scalded skin syndrome

Staphylococcal scalded skin syndrome (SSSS) is a severe cutaneous reaction characterized by widespread blistering and exfoliation of the epidermis, resembling a burn. It is caused by epidermolytic toxins produced by certain strains of Staphylococcus aureus, leading to superficial skin shedding. This condition primarily affects infants and young children, though it can occur in adults, particularly those with renal insufficiency or immunocompromise.

Use this code when documentation clearly indicates a diagnosis of staphylococcal scalded skin syndrome, often presenting with fever, irritability, and diffuse erythema followed by flaccid bullae and desquamation. The diagnosis is typically clinical, supported by a positive bacterial culture from a non-skin site (e.g., nasopharynx, conjunctiva, blood) or a skin biopsy showing superficial epidermal cleavage.

• Differentiate carefully from bullous impetigo (L01.03), which involves localized blistering and crusting, and is an Excludes1 note.
• Ensure documentation specifies "scalded skin syndrome" and not just a general staphylococcal infection, as the latter would require a different code.
• Do not confuse with toxic epidermal necrolysis (L51.2), a drug-induced reaction with full-thickness epidermal necrosis, also an Excludes1 note.
