ICD-10: Y21.4

ICD-10 code Y21.4 specifically refers to "Drowning and submersion in natural water, undetermined intent." This classification is part of the broader category of drowning incidents, which are significant public health concerns globally. Below is a detailed clinical description and relevant information regarding this code.

Clinical Description

Definition

Drowning is defined as the process of experiencing respiratory impairment from submersion or immersion in liquid. The term "submersion" refers to being under the surface of the water, while "immersion" involves being in water but not necessarily submerged. The intent behind the drowning incident can vary, and in cases classified under Y21.4, the intent is undetermined, meaning it is unclear whether the drowning was accidental, suicidal, or due to other circumstances.

Clinical Presentation

Patients who have experienced drowning may present with a variety of symptoms depending on the duration of submersion and the nature of the incident. Common clinical features include:

• Respiratory Distress: Difficulty breathing or inability to breathe due to water in the lungs.
• Cyanosis: A bluish discoloration of the skin, particularly around the lips and extremities, indicating low oxygen levels.
• Altered Consciousness: Ranging from confusion to loss of consciousness, depending on the severity of hypoxia.
• Pulmonary Complications: Potential for aspiration pneumonia or acute respiratory distress syndrome (ARDS) following the incident.

Risk Factors

Several factors can increase the risk of drowning in natural water settings, including:

• Environmental Conditions: Strong currents, waves, and cold water temperatures can contribute to drowning incidents.
• Lack of Supervision: Children and inexperienced swimmers are particularly vulnerable when not adequately supervised.
