Unsp injury of heart, unsp w or w/o hemopericardium, sequela

This code signifies a long-term or late effect of an unspecified injury to the heart, which may or may not have involved bleeding into the pericardial sac. It indicates that the initial acute cardiac injury has resolved, but the patient continues to experience residual effects or complications directly attributable to that past event.

Apply this code when documenting a patient's current condition that is a sequela of a prior, unspecified heart injury, such as chronic pericardial thickening, persistent arrhythmias, or heart failure directly resulting from the old injury. This code is appropriate when the specific nature of the original cardiac trauma is not documented or is unknown, but its lasting impact is evident.

• Always sequence this sequela code first, followed by codes for the specific current manifestations or complications.
• Ensure documentation clearly links the current condition to a past heart injury and specifies it as a sequela.
• Avoid using this code for acute injuries; use the appropriate acute injury codes for initial encounters.
