ICD-10: B99.8

The ICD-10-CM code B99.8 is designated for "Other infectious diseases." This code falls under the broader category of infectious and parasitic diseases, which are classified from A00 to B99 in the ICD-10 system. Here’s a detailed overview of this code, including its clinical description, usage, and relevant guidelines.

Clinical Description

Definition

The code B99.8 is used to classify infectious diseases that do not fall into more specific categories within the ICD-10 coding system. This includes a variety of infectious diseases that are not explicitly defined by other codes, allowing healthcare providers to document cases that may not have a clear or established diagnosis.

Examples of Conditions

While the code itself does not specify particular diseases, it can be applied to a range of conditions such as:
- Unspecified viral infections
- Unspecified bacterial infections
- Rare or emerging infectious diseases that do not have a specific ICD-10 code

This code is particularly useful in clinical settings where a patient presents with symptoms of an infectious disease, but the exact pathogen or disease is not identified through standard diagnostic methods.

Usage Guidelines

When to Use B99.8

• Unspecified Cases: Use B99.8 when the infectious disease is known but does not fit into a more specific category. This is common in cases where laboratory results are pending or when the disease is atypical.
• Emerging Infections: In situations involving newly identified infectious diseases that lack specific coding, B99.8 serves as a placeholder until more information becomes available.
