The ICD-10-CM A00-B99 encompasses diverse medical codes for "certain infectious and parasitic diseases." These codes cover a spectrum of illnesses caused by infectious agents such as bacteria, viruses, fungi, protozoa, and parasites.
We've grouped the codes into two main categories: Infectious Diseases and Parasitic Diseases. Learn about the key diagnosis under each range.
ICD-10-CM Code A00-A79: Infectious Diseases
Infectious Diseases (A00-A79) encompass a broad category of illnesses caused by microorganisms, including bacteria, viruses, protozoa, and parasites. These diseases are typically transmitted from one person to another, from animals to humans, or through contaminated food and water.
Infectious diseases can vary widely in severity, ranging from common illnesses like the flu to life-threatening conditions such as tuberculosis and HIV/AIDS. There are different categories under infectious diseases.
1. Bacterial Infections (ICD Code: Range A00-A49)
As the name suggests, bacterial infections cover diseases caused by bacteria. These infections can affect various body systems and organs.
2. Viral Infections (A80-B34)
This range refers to diagnoses caused by viruses ranging from the common cold to more severe diseases like HIV/AIDS.
Viral diseases class may also cover Chronic viral hepatitis C diagnosis, a long-term viral infection of the liver caused by the hepatitis C virus (HCV), with its ICD Code being B18.2.
3. Protozoal and Helminthic Infections (A50-B64)
These are infections caused by protozoa (single-celled organisms) and helminths (parasitic worms) and can lead to diseases like Malaria and Tapeworm infections.
This ICD Code cluster may also cover fungal infection. For instance, Onychomycosis' ICD 10 code is B35.1. Onychomycosis is a fungal infection of the nails, specifically the toenails or fingernails.
ICD-10-CM Code B65-B83: Parasitic Diseases
The second classification under the ICD 10 Range (A00-B99) is the Parasitic Diseases. It covers the code range B65-B83, referring to illnesses caused by various parasitic organisms, including helminths (worms) and protozoa.
These diseases are characterized by their transmission from one host to another, often involving intermediate hosts like insects or snails. Parasitic diseases manifest in diverse ways, affecting different body systems, and may demonstrate varied symptoms and complications. The severity of these diseases can vary from mild discomfort to life-threatening conditions.
1. Helminthiases (B65-B83)
Helminthic infections are diseases brought by parasitic worms that result in diagnoses like Ascariasis and Trichuriasis.

ICD-10-CM codes within the range A00-B99 are essential for accurately diagnosing, treating, billing, and researching infectious and parasitic diseases. Proper documentation is crucial for effective coding. These codes contribute to the overall healthcare system by facilitating disease management, resource allocation, and epidemiological surveillance.
Disclaimer: The information provided in this blog regarding the International Classification of Diseases (ICD) codes is intended for informational purposes only. We strive to offer accurate and up-to-date content. However, the ICD codes are subject to changes, updates, and modifications by authoritative bodies such as the Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and other relevant healthcare organizations. These changes can occur due to advancements in medical knowledge, new diseases, evolving diagnostic criteria, or updates in medical terminology.
- What is ICD-10-CM, and why is it important for infectious diseases?
ICD-10-CM A00-B99 is a coding system that classifies infectious diseases for diagnosis, billing, and research purposes. It's crucial for tracking and managing infections effectively.
- How can healthcare professionals use ICD-10-CM codes effectively?
Healthcare professionals should accurately document diseases, specifying type, site, and complications, to use ICD-10-CM codes effectively.
- What are the primary differences between viral, bacterial, and parasitic infections in coding?
Differences include the type of microorganism (virus, bacteria, parasite), specific codes, and the need for detailed documentation.
- Are there any recent updates or changes in the ICD-10-CM codes for infectious diseases?
For updates, healthcare professionals should refer to resources such as the Centers for Disease Control and Prevention (CDC) and relevant coding guidelines.
