Postprocedural heart failure following other surgery

This code signifies the development of heart failure as a direct complication following any surgical procedure other than cardiac surgery. It indicates a new onset or exacerbation of heart failure that is causally linked to the stress or physiological changes induced by a non-cardiac operation.

This code is appropriate when a patient experiences heart failure post-operatively, and the medical record clearly links its onset or worsening to a non-cardiac surgical intervention. Documentation should specify the type of surgery performed and the temporal relationship to the heart failure diagnosis.

• Always sequence this code after the code for the underlying heart failure (e.g., I50.x).
• Ensure the documentation explicitly states the heart failure is "postprocedural" and identifies the surgery as non-cardiac.
• Do not use this code if the heart failure is a pre-existing condition that was not exacerbated by the surgery, or if the surgery was cardiac in nature.
