Oth postproc cardiac functn disturb fol cardiac surgery

This code represents any functional cardiac disturbance, other than acute heart failure or cardiac arrest, that occurs as a direct consequence of a cardiac surgical procedure. This includes conditions like post-cardiotomy syndrome, persistent arrhythmias, or new-onset valvular dysfunction that are directly attributable to the surgery itself. It signifies a complication or adverse effect of the cardiac intervention.

Use this code when documentation clearly links a new or worsened cardiac functional issue to a recent cardiac surgery, and the issue is not acute heart failure or cardiac arrest. This code is appropriate for conditions such as new-onset atrial fibrillation post-coronary artery bypass graft (CABG) or persistent pericardial effusion causing functional impairment after valve replacement. Documentation should specify the cardiac surgery and the resulting functional disturbance.

• Always sequence this code after the primary complication or specific cardiac condition it describes, if applicable, or as a secondary diagnosis when the functional disturbance is the reason for encounter.
• Distinguish carefully from I97.110 (Postprocedural cardiac arrest) and I97.130 (Postprocedural acute heart failure), as these are distinct complications.
• Ensure the medical record explicitly states the causal link between the cardiac surgery and the functional disturbance to support code assignment.
