Lung transplant rejection

This code signifies the body's immune response against a transplanted lung, leading to its dysfunction or failure. It encompasses various forms of rejection, including hyperacute, acute, and chronic, that compromise the viability and function of the allograft.

Apply this code when documentation clearly indicates a diagnosis of lung transplant rejection, regardless of the specific type or severity. This includes situations where the patient is experiencing symptoms such as dyspnea, fever, or declining lung function post-transplant, and diagnostic tests confirm rejection.

• Always look for specific documentation of "rejection" of the lung transplant.
• Do not use this code for post-transplant complications that are not explicitly stated as rejection (e.g., infection, surgical complications).
• Consider additional codes for specific manifestations or complications of the rejection, if documented.
