ICD-10: S20.363

The ICD-10 code S20.363 refers to an insect bite (nonvenomous) affecting the bilateral front wall of the thorax. This code is part of the broader category of injuries related to insect bites, which are classified under Chapter 19 of the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) system.

Clinical Description

Definition

An insect bite is defined as a puncture or break in the skin caused by an insect, which can lead to various symptoms ranging from mild irritation to severe allergic reactions. The term "nonvenomous" indicates that the insect does not inject venom that could cause systemic toxicity or severe reactions.

Affected Area

The bilateral front wall of the thorax refers to the anterior chest area, encompassing both sides of the thoracic region. This area is significant as it houses vital organs, including the heart and lungs, and is also a common site for insect bites, especially in outdoor settings.

Symptoms

Symptoms associated with nonvenomous insect bites may include:
- Localized swelling and redness
- Itching or burning sensation
- Pain at the site of the bite
- Possible development of a rash or hives in sensitive individuals

In most cases, these symptoms are mild and resolve without medical intervention. However, in some instances, secondary infections may occur if the bite site is not properly cared for.

Coding Details

Code Structure

• S20: This is the category for "Injury of thorax."
• .36: This specific code indicates "Insect bite (nonvenomous)."
• 3: The final digit specifies that the injury is bilateral, affecting both sides of the thorax.

Usage

The S20.363 code is used in clinical settings to document cases of nonvenomous insect bites affecting the thoracic area. Accurate coding is essential for proper billing, treatment planning, and epidemiological tracking of insect-related injuries.
