Contusion of heart, unsp w or w/o hemopericardium, sequela

This code signifies a bruise to the heart muscle, which may or may not be accompanied by blood accumulation within the pericardial sac, occurring as a late effect or complication of an initial injury. It indicates that the specific nature of the heart contusion (e.g., specific chamber affected) is not documented.

This code is appropriate for documenting a chronic or residual condition resulting from a previous cardiac contusion, such as persistent arrhythmias, heart failure, or other long-term sequelae. It should be used when the initial injury has healed, but its lasting effects on the heart are still present and require ongoing management.

• Always assign an external cause code (V, W, X, Y codes) to describe the circumstances of the original injury that led to the sequela.
• Ensure documentation clearly supports the "sequela" nature of the condition, indicating it's a late effect rather than an acute injury.
• If the specific type of heart contusion or the presence/absence of hemopericardium is known, a more specific code should be used instead.
