ICD-10 Code A28

Other zoonotic bacterial diseases, not elsewhere classified

Version 2019 Non-Billable Code
ICD-10: A28
Short Description:Other zoonotic bacterial diseases, not elsewhere classified
Long Description:Other zoonotic bacterial diseases, not elsewhere classified

Not Valid for Submission

ICD-10 A28 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of other zoonotic bacterial diseases, not elsewhere classified. The code is NOT valid for the year 2019 for the submission of HIPAA-covered transactions.

Consider the following ICD-10 codes with a higher level of specificity:

  • A28.0 - Pasteurellosis
  • A28.1 - Cat-scratch disease
  • A28.2 - Extraintestinal yersiniosis
  • A28.8 - Other specified zoonotic bacterial diseases, not elsewhere classified
  • A28.9 - Zoonotic bacterial disease, unspecified

Code Classification

  • Certain infectious and parasitic diseases (A00–B99)
    • Certain zoonotic bacterial diseases (A20-A28)
      • Other zoonotic bacterial diseases, not elsewhere classified (A28)

Information for Patients


Bacterial Infections

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most bacteria won't hurt you - less than 1 percent of the different types make people sick. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese.

But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.

Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them causing antibiotic resistance. Later, you could get or spread an infection that those antibiotics cannot cure.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
