Postproc cardiac insufficiency following cardiac surgery

This code describes a state of impaired cardiac function, such as reduced cardiac output or heart failure, that develops as a direct consequence of a cardiac surgical procedure. It signifies the heart's inability to adequately meet the body's metabolic demands after an operation on the heart itself. This insufficiency can manifest as new-onset or worsening heart failure symptoms.

Use this code when documentation clearly links a patient's new or exacerbated cardiac insufficiency to a recent cardiac surgical intervention. This includes scenarios where the heart's pumping ability is compromised post-operatively, requiring medical management or further intervention. Supporting documentation should specify the cardiac surgery performed and the subsequent development of cardiac insufficiency.

• Ensure the documentation explicitly states a causal link between the cardiac surgery and the insufficiency.
• Do not use for pre-existing cardiac insufficiency unless it is significantly worsened by the surgery and documented as such.
• Sequence this code as a secondary diagnosis following the code for the underlying cardiac condition or complication that necessitated the surgery, if applicable.
