Dengue hemorrhagic fever (A91)

The ICD-10 code A91 is used specifically to identify and classify dengue hemorrhagic fever, a severe form of dengue virus infection. This code is essential for documenting cases where bleeding and plasma leakage complicate a typical dengue infection.

Dengue hemorrhagic fever, sometimes referred to as dengue shock syndrome or classified in severity grades I through IV, involves critical symptoms such as bleeding, low platelet counts, and blood plasma leakage. These detailed synonyms help medical coders select the right code when encountering these terms in clinical records. The ICD-10 code for dengue hemorrhagic fever (A91) specifically distinguishes this serious viral infection from standard dengue fever, supporting accurate diagnosis, treatment planning, and healthcare reporting related to this potentially life-threatening condition.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Dengue

An acute febrile disease transmitted by the bite of AEDES mosquitoes infected with DENGUE VIRUS. It is self-limiting and characterized by fever, myalgia, headache, and rash. SEVERE DENGUE is a more virulent form of dengue.

Dengue Vaccines

Vaccines or candidate vaccines used to prevent infection with DENGUE VIRUS. These include live-attenuated, subunit, DNA, and inactivated vaccines.

Dengue Virus

A species of the genus FLAVIVIRUS which causes an acute febrile and sometimes hemorrhagic disease in man. Dengue is mosquito-borne and four serotypes are known.

Flavivirus

A genus of FLAVIVIRIDAE containing several subgroups and many species. Most are arboviruses transmitted by mosquitoes or ticks. The type species is YELLOW FEVER VIRUS.

Severe Dengue

A virulent form of dengue characterized by THROMBOCYTOPENIA and an increase in vascular permeability (grades I and II) and distinguished by a positive pain test (e.g., TOURNIQUET PAIN TEST). When accompanied by SHOCK (grades III and IV), it is called dengue shock syndrome.
