ICD-10: S20.329

The ICD-10-CM code S20.329 refers to a blister (nonthermal) located on the unspecified front wall of the thorax. This code is part of the broader category of injuries, specifically those related to the thorax, which encompasses various types of trauma and their corresponding manifestations.

Clinical Description

Definition of Blister

A blister is a small pocket of fluid that forms between the upper layers of the skin. It can be caused by various factors, including friction, burns, or other forms of skin irritation. In the case of a nonthermal blister, the formation is not due to heat but may result from mechanical injury, allergic reactions, or other dermatological conditions.

Location

The front wall of the thorax refers to the anterior aspect of the chest, which includes the sternum and the surrounding areas. The thorax houses vital organs such as the heart and lungs, making any injury in this region significant.

Symptoms

Patients with a blister in this area may experience:
- Pain or discomfort at the site of the blister.
- Swelling or redness surrounding the blister.
- Possible drainage of fluid if the blister ruptures.

Diagnosis

Diagnosis typically involves a physical examination where a healthcare provider assesses the blister's characteristics, including size, appearance, and any associated symptoms. The history of the injury or condition leading to the blister is also crucial for accurate diagnosis.
