Major laceration of heart with hemopericardium, init encntr

This code signifies a significant tear or cut in the heart muscle, accompanied by the accumulation of blood within the pericardial sac (the membrane surrounding the heart). This condition is life-threatening due to the potential for cardiac tamponade and severe hemodynamic compromise.

Apply this code for patients presenting with a traumatic injury to the chest resulting in a deep laceration of the heart, confirmed by imaging or surgical exploration, and evidence of blood in the pericardium. This is typically seen in penetrating chest trauma such as stab wounds or gunshot wounds.

• Ensure documentation clearly specifies a "major" laceration and the presence of hemopericardium.
• Verify that this is the initial encounter for treatment of this specific injury.
• Code additional associated injuries, such as open wounds of the chest wall, separately.
