Leptospirosis icterohemorrhagica

This code represents Weil's disease, the most severe form of leptospirosis. It is characterized by jaundice, hemorrhage, renal failure, and often myocarditis, caused by infection with Leptospira bacteria. This systemic infection can lead to significant organ damage and has a high mortality rate if untreated.

Use this code when documentation clearly indicates a diagnosis of Weil's disease or icterohemorrhagic leptospirosis. Supporting documentation should detail symptoms such as jaundice, bleeding diathesis, acute kidney injury, and laboratory confirmation of Leptospira infection. This code is appropriate for severe cases requiring hospitalization and intensive care.

• Ensure documentation specifies the icterohemorrhagic form; otherwise, a more general leptospirosis code may be appropriate.
• Code any associated organ failures (e.g., acute renal failure, hepatic failure) as secondary diagnoses.
• Do not confuse with other forms of leptospirosis that do not involve severe jaundice and hemorrhage.
