B94 - Sequelae of other and unspecified infectious and parasitic diseases

Version 2023
ICD-10:B94
Short Description:Sequelae of other and unsp infectious and parasitic diseases
Long Description:Sequelae of other and unspecified infectious and parasitic diseases
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Certain infectious and parasitic diseases (A00–B99)
    • Sequelae of infectious and parasitic diseases (B90-B94)
      • Sequelae of other and unsp infectious and parasitic diseases (B94)

B94 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 sequelae of other and unspecified infectious and parasitic diseases. 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.

B94 is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like e of other and unspecified infectious and parasitic diseases. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Unspecified diagnosis codes like B94 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding for Sequelae of other and unsp infectious and parasitic diseases

Non-specific codes like B94 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 sequelae of other and unsp infectious and parasitic diseases:

  • BILLABLE CODE - Use B94.0 for Sequelae of trachoma
  • BILLABLE CODE - Use B94.1 for Sequelae of viral encephalitis
  • BILLABLE CODE - Use B94.2 for Sequelae of viral hepatitis
  • BILLABLE CODE - Use B94.8 for Sequelae of other specified infectious and parasitic diseases
  • BILLABLE CODE - Use B94.9 for Sequelae of unspecified infectious and parasitic disease

Infectious Diseases

Germs, or microbes, are found everywhere - in the air, soil, and water. There are also germs on your skin and in your body. Many of them are harmless, and some can even be helpful. But some of them can make you sick. Infectious diseases are diseases that are caused by germs.

There are many different ways that you can get an infectious disease:

There are four main kinds of germs:

Infectious diseases can cause many different symptoms. Some are so mild that you may not even notice any symptoms, while others can be life-threatening. There are treatments for some infectious diseases, but for others, such as some viruses, you can only treat your symptoms. You can take steps to prevent many infectious diseases:

Parasitic Diseases

Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.

Parasites range in size from tiny, one-celled organisms called protozoa to worms that can be seen with the naked eye. Some parasitic diseases occur in the United States. Contaminated water supplies can lead to Giardia infections. Cats can transmit toxoplasmosis, which is dangerous for pregnant women. Others, like malaria, are common in other parts of the world.

If you are traveling, it's important to drink only water you know is safe. Prevention is especially important. There are no vaccines for parasitic diseases. Some medicines are available to treat parasitic infections.
