Rupture of card wall w/o hemoperic as current comp fol AMI

This code signifies a tear or perforation in the heart muscle (ventricle, atrium, or septum) that occurs as a direct consequence of a recent heart attack, but without associated bleeding into the pericardial sac. This is a severe, life-threatening mechanical complication of myocardial infarction.

Apply this code when documentation clearly states a cardiac wall rupture following an acute MI, and specifically notes the absence of hemopericardium. This typically occurs within days to weeks post-infarction. Supporting documentation would include imaging reports (e.g., echocardiogram) and physician notes detailing the rupture and lack of pericardial effusion.

• Always sequence the acute myocardial infarction (I21.-) first, followed by this code.
• Distinguish from cardiac tamponade (I31.2) or hemopericardium (I31.0), which involve blood in the pericardial sac.
• Ensure the documentation specifies "without hemopericardium" to accurately assign this code; otherwise, consider I23.0.
