Kidney transplant rejection

This code signifies the body's immune system attacking a transplanted kidney, leading to its dysfunction or failure. It encompasses various forms of rejection, including acute and chronic, which can manifest through different clinical and pathological findings.

Apply this code when documentation clearly indicates a diagnosis of kidney transplant rejection. This includes situations where a patient presents with signs and symptoms consistent with rejection, and diagnostic tests confirm the immune-mediated attack on the allograft. It is appropriate for both initial and subsequent encounters related to the management of rejection.

• Always ensure the documentation explicitly states "rejection" of the kidney transplant, not just "failure" or "complication."
• Look for specific types of rejection (e.g., acute, chronic, antibody-mediated) as these may require additional, more specific codes if available.
• Do not use this code for complications of a kidney transplant that are not directly related to immune rejection (e.g., surgical site infection, ureteral stricture).
