Impetigo herpetiformis

This code describes impetigo herpetiformis, a rare and severe pustular dermatosis that typically occurs during pregnancy. It is characterized by widespread sterile pustules on an erythematous base, often accompanied by systemic symptoms such as fever, chills, and malaise. This condition is considered a variant of pustular psoriasis.

Use this code when documentation clearly indicates a diagnosis of impetigo herpetiformis, particularly in pregnant patients presenting with acute generalized pustular eruptions. Supporting documentation should detail the characteristic skin lesions, systemic involvement, and the context of pregnancy.

• Differentiate from other forms of impetigo (e.g., bacterial impetigo) which are distinct conditions.
• Consider an additional code for the pregnancy status if not already captured.
• Ensure documentation specifies "herpetiformis" to distinguish from common impetigo.
