Major laceration of heart with hemopericardium, subs encntr

This code signifies a significant tear or wound to the heart muscle that has resulted in blood accumulating within the pericardial sac, occurring during a follow-up visit. This condition is a severe cardiac injury that can lead to cardiac tamponade and is often life-threatening.

This code is appropriate for subsequent encounters where a patient is being treated for a previously diagnosed major heart laceration with hemopericardium. This includes follow-up visits for monitoring, wound care, or management of complications related to the initial injury. It should be used after the initial acute phase of treatment.

• Ensure documentation clearly indicates a "subsequent encounter" for the heart laceration and hemopericardium.
• Verify the laceration is explicitly described as "major" to support this specific code.
• Always code the underlying cause of the injury (e.g., assault, accident) as an external cause code.
