Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Arthropod-borne viral fevers and viral hemorrhagic fevers
      (A90-A99)
      • Other viral hemorrhagic fevers, not elsewhere classified
        (A98)

A98 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other viral hemorrhagic fevers, not elsewhere classified. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other viral hemorrhagic fevers, not elsewhere classified

Non-specific codes like A98 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other viral hemorrhagic fevers, not elsewhere classified:

  • Use A98.0 for Crimean-Congo hemorrhagic fever - BILLABLE CODE

  • Use A98.1 for Omsk hemorrhagic fever - BILLABLE CODE

  • Use A98.2 for Kyasanur Forest disease - BILLABLE CODE

  • Use A98.3 for Marburg virus disease - BILLABLE CODE

  • Use A98.4 for Ebola virus disease - BILLABLE CODE

  • Use A98.5 for Hemorrhagic fever with renal syndrome - BILLABLE CODE

  • Use A98.8 for Other specified viral hemorrhagic fevers - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

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.
  • chikungunya hemorrhagic fever A92.0
  • dengue hemorrhagic fever A91

Patient Education


Hemorrhagic Fevers

Viral hemorrhagic fevers (VHFs) are a group of illnesses caused by four families of viruses. These include the Ebola and Marburg, Lassa fever, and yellow fever viruses. VHFs have common features: they affect many organs, they damage the blood vessels, and they affect the body's ability to regulate itself. Some VHFs cause mild disease, but some, like Ebola or Marburg, cause severe disease and death.

VHFs are found around the world. Specific diseases are usually limited to areas where the animals that carry them live. For example, Lassa fever is limited to rural areas of West Africa where rats and mice carry the virus.

The risk for travelers is low, but you should avoid visiting areas where there are disease outbreaks. Because there are no effective treatments for some of these viral infections, there is concern about their use in bioterrorism.
