Heart-lung transplant rejection

This code signifies the body's immune response against a transplanted heart and lung organ, leading to dysfunction or failure of the graft. Rejection can manifest acutely or chronically, impacting the patient's overall health and requiring specific medical interventions.

Assign this code for patients experiencing any form of immunological rejection following a combined heart and lung transplant. This includes both cellular and humoral rejection, as well as acute or chronic presentations confirmed by biopsy or clinical criteria.

• Ensure documentation clearly specifies "heart-lung" transplant rejection, not just heart or lung alone.
• Look for terms like "graft dysfunction," "rejection episode," or "allograft rejection" in the context of a heart-lung transplant.
• Consider additional codes for specific manifestations or complications of the rejection, such as organ failure or infection.
