I23.5
ICD-10-CMRupture of papillary muscle as current complication following acute myocardial infarction
This code signifies a tear or break in one of the papillary muscles of the heart, occurring as a direct and immediate consequence of a recent acute myocardial infarction (heart attack). This complication severely impairs the function of the mitral or tricuspid valve, leading to acute valvular regurgitation.
Apply this code when documentation explicitly states a rupture of the papillary muscle and clearly links it as a current complication following an acute MI. This typically presents with sudden onset of severe heart failure symptoms and a new murmur after a recent MI.
