Non-Billable Code
ICD-10:B97.3
Short Description:Retrovirus as the cause of diseases classified elsewhere
Long Description:Retrovirus as the cause of diseases classified elsewhere
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Certain infectious and parasitic diseases (A00–B99)
    • Bacterial and viral infectious agents (B95-B97)
      • Viral agents as the cause of diseases classified elsewhere (B97)

B97.3 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of retrovirus as the cause of diseases classified elsewhere. The code is not specific and is NOT valid for the year 2023 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 for Retrovirus as the cause of diseases classified elsewhere

Non-specific codes like B97.3 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for retrovirus as the cause of diseases classified elsewhere:

  • BILLABLE CODE - Use B97.30 for Unspecified retrovirus as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.31 for Lentivirus as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.32 for Oncovirus as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.33 for Human T-cell lymphotrophic virus, type I [HTLV-I] as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.34 for Human T-cell lymphotrophic virus, type II [HTLV-II] as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.35 for Human immunodeficiency virus, type 2 [HIV 2] as the cause of diseases classified elsewhere
  • BILLABLE CODE - Use B97.39 for Other retrovirus as the cause of diseases classified elsewhere

Tabular List of Diseases and Injuries

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


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.

Viral Infections

Viruses are very tiny germs. They are made of genetic material inside of a protein coating. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19.

Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.

When you get a virus, you may not always get sick from it. Your immune system may be able to fight it off.

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