Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Arthropod-borne viral fevers and viral hemorrhagic fevers
      (A90-A99)
      • Other mosquito-borne viral fevers
        (A92)

A92 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 mosquito-borne viral fevers. 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 mosquito-borne viral fevers

Non-specific codes like A92 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 mosquito-borne viral fevers:

  • Use A92.0 for Chikungunya virus disease - BILLABLE CODE

  • Use A92.1 for O'nyong-nyong fever - BILLABLE CODE

  • Use A92.2 for Venezuelan equine fever - BILLABLE CODE

  • A92.3 for West Nile virus infection - NON-BILLABLE CODE

  • Use A92.30 for West Nile virus infection, unspecified - BILLABLE CODE

  • Use A92.31 for West Nile virus infection with encephalitis - BILLABLE CODE

  • Use A92.32 for West Nile virus infection with other neurologic manifestation - BILLABLE CODE

  • Use A92.39 for West Nile virus infection with other complications - BILLABLE CODE

  • Use A92.4 for Rift Valley fever - BILLABLE CODE

  • Use A92.5 for Zika virus disease - BILLABLE CODE

  • Use A92.8 for Other specified mosquito-borne viral fevers - BILLABLE CODE

  • Use A92.9 for Mosquito-borne viral fever, unspecified - 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.
  • Ross River disease B33.1

Viral Infections

What are viruses?

Viruses are very tiny germs. They are made of genetic material (either DNA or RNA) inside of a protein coating. There are a huge number of viruses on earth. Only a small number of them can infect humans. Those viruses can infect our cells, which may cause disease. Some of the diseases that viruses can cause include the common cold, the flu, COVID-19, and HIV.

How are viruses spread?

Viruses can be spread in different ways:

  • Through droplets and particles that are breathed out by someone who has the infection. You might breathe in the droplets or particles, or they could land on your mouth, nose, or eyes.
  • By touching surfaces or objects that have the virus on them and then touching your mouth, nose, or eyes.
  • From the pregnant parent to the baby during pregnancy.
  • Through contaminated food or water.
  • By being bitten by an infected insect or animal.
  • Through sexual contact (usually vaginal, anal and oral sex) with someone who has the infection.

How do viruses cause disease?

Viruses are like hijackers. They invade living, normal cells. They then use those cells to multiply (make copies of themselves). This process is also called replication. The process can kill, damage, or change the infected cells. Sometimes this can make you sick. The symptoms can range from mild to very severe. Other times, your immune system may be able to fight it off and you may not have any symptoms.

Each different virus usually only infects one type of cell in your body. For example, hepatitis viruses affect the cells in the liver. HIV infects a certain type of immune system cell.

What are the treatments for viral infections?

For most viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus. There are antiviral medicines to treat some viral infections. Antibiotics do not work for viral infections.

Can viral infections be prevented?

Vaccines can help prevent you from getting many viral diseases. You may be able to prevent some viral infections by:

  • Proper hand washing.
  • Paying attention to food safety.
  • Cleaning surfaces that may be infected with germs.
  • Avoiding contact with wild animals.
  • Preventing insect bites by using insect repellent when you go outdoors. If you travel to an area that has a high risk of diseases from insect bites, also wear long pants, shirts, and socks.
  • Practicing safe sex (using a condom every time you have anal, vaginal, or oral sex).
  • Avoiding close contact with people who are sick.
