Dengue fever [classical dengue] (A90)
The ICD-10 code A90 is used to classify dengue fever, commonly known as classical dengue, a viral infection transmitted by mosquitoes. This code specifically captures cases of dengue without complications or additional warning signs.
Dengue fever, often referred to simply as Dengue or recognized in related terms like dengue virus encephalitis and myelitis caused by Dengue virus, represents an acute febrile illness caused by the dengue virus. The ICD-10 code A90 helps medical coders and healthcare professionals document and report this infection accurately. Utilizing this code distinguishes uncomplicated dengue cases from more severe forms, ensuring precise classification in patient records and statistical data. For those searching for the ICD-10 code for dengue fever, A90 clearly identifies classical dengue without warning signs, facilitating better diagnosis tracking and treatment planning.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same 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.
