Dengue hemorrhagic fever

This code represents a severe form of dengue infection characterized by plasma leakage, hemorrhage, and organ impairment. It is a potentially life-threatening complication of dengue virus infection, often presenting with fever, bleeding manifestations, and signs of shock.

Assign this code when documentation explicitly states "dengue hemorrhagic fever" or "DHF." This diagnosis is typically supported by clinical findings such as petechiae, ecchymoses, epistaxis, gastrointestinal bleeding, and evidence of plasma leakage (e.g., ascites, pleural effusion, hemoconcentration).

• Differentiate from uncomplicated dengue fever; this code requires documentation of hemorrhagic manifestations.
• Do not use for "dengue fever with hemorrhage" if it does not meet the criteria for hemorrhagic fever (e.g., just minor bleeding without plasma leakage).
• Always sequence this code first if it is the primary reason for the encounter.
