Heart-lung transplant failure

This code signifies the complete or partial cessation of function of a transplanted heart-lung organ. It indicates that the allograft is no longer adequately performing its physiological role, leading to significant patient morbidity and potential mortality.

Apply this code when documentation clearly states the failure of a previously transplanted heart-lung organ. This includes situations where the allograft is no longer viable, requires re-transplantation, or is the primary cause of the patient's current critical condition.

• Ensure documentation specifies "heart-lung" transplant failure, not just heart or lung failure separately.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Look for associated complications or causes of failure (e.g., rejection, infection) and code them additionally.
