Postcardiotomy syndrome

Postcardiotomy syndrome is an inflammatory reaction that can occur days to months following cardiac surgery, myocardial infarction, or pericardial injury. It is characterized by fever, pleuritic chest pain, pericarditis, and/or pleural effusion. This syndrome is thought to be an autoimmune response to damaged cardiac tissue.

Assign this code for patients presenting with symptoms consistent with postcardiotomy syndrome after any cardiac surgical procedure, such as coronary artery bypass grafting (CABG) or valve replacement. Documentation should clearly indicate the diagnosis of postcardiotomy syndrome, often supported by clinical findings, imaging (e.g., echocardiogram showing pericardial effusion), and laboratory results (e.g., elevated inflammatory markers).

• Do not confuse with postpericardiotomy syndrome, which is a broader term.
• Always sequence this code after the code for the underlying cardiac surgery or myocardial infarction, if still relevant to the current encounter.
• Ensure documentation specifies "postcardiotomy syndrome" rather than general postoperative complications.
