Rupture of chordae tendineae as current complication following acute myocardial infarction
ICD-10 I23.4 is a billable code used to indicate a diagnosis of rupture of chordae tendineae as current complication following acute myocardial infarction.
Rupture of chordae tendineae is a serious complication that can occur following an acute myocardial infarction (AMI), particularly in cases of extensive myocardial damage. The chordae tendineae are fibrous cords that connect the papillary muscles to the heart valves, specifically the mitral and tricuspid valves. When these structures rupture, it can lead to acute valvular insufficiency, resulting in severe hemodynamic instability and potentially life-threatening conditions such as cardiogenic shock. Clinically, patients may present with sudden onset of dyspnea, hypotension, and signs of heart failure. The progression of this complication can be rapid, necessitating immediate intervention. Diagnostic considerations include echocardiography, which can visualize the rupture and assess the severity of regurgitation. In some cases, transesophageal echocardiography may be required for better visualization. Timely recognition and management are critical to improving outcomes in affected patients, often requiring surgical intervention to repair the valve or replace it entirely.

I23.4 specifically covers the rupture of chordae tendineae as a complication following an acute myocardial infarction. This includes cases where the rupture leads to significant mitral or tricuspid valve insufficiency, resulting in acute heart failure.
I23.4 should be used when there is clear documentation of chordae tendineae rupture following an acute myocardial infarction. It is distinct from codes that describe myocardial infarction without complications or other cardiac conditions that do not involve this specific rupture.
Documentation must include clinical findings indicative of chordae tendineae rupture, such as echocardiographic evidence, patient symptoms, and treatment interventions. Operative reports detailing surgical repair or replacement of the affected valve are also critical.
