Lung transplant failure

This code signifies the complete or partial inability of a transplanted lung to function adequately after implantation. It encompasses both primary graft dysfunction, occurring shortly after surgery, and chronic rejection, which develops over a longer period and leads to progressive loss of lung function.

Use this code when documenting a patient who has undergone a lung transplant and is experiencing complications where the transplanted lung is failing to perform its intended function. This includes cases of acute rejection, chronic allograft dysfunction, or other forms of graft failure requiring medical intervention or re-transplantation.

• Always code the specific type of lung transplant complication if known (e.g., acute rejection, chronic rejection) in addition to this code.
• Ensure documentation clearly supports the diagnosis of transplant failure, including clinical signs, symptoms, and diagnostic findings.
• Consider sequencing this code as a primary diagnosis when the transplant failure is the main reason for the encounter, or as a secondary diagnosis when it's a significant co-morbidity.
