Y24: Other and unspecified firearm discharge, undetermined intent

Other and unspecified firearm discharge, undetermined intent (Y24) refers to injuries or fatalities where the cause or intent—whether accidental, intentional, or assault—is undetermined at the time of documentation. These cases require careful clinical management, detailed investigation, and follow-up to clarify circumstances and ensure appropriate care.

Symptoms

• Trauma injuries from falls, crashes, or impacts
• Gunshot or explosion-related wounds
• Burns or respiratory injuries from smoke or fire
• Drowning-related respiratory failure
• Lacerations, puncture wounds, or blunt force injuries
• Shock, loss of consciousness, or cardiac arrest
• Psychological distress if the event involved violence or uncertainty

Diagnosis

Diagnosis includes trauma evaluations, imaging studies (CT scans, X-rays, MRIs), wound assessment, toxicology screenings, and forensic documentation. Special attention is given to understanding the mechanism of injury, and multidisciplinary teams may be involved to determine the cause and intent over time.
