Skin graft (allograft) rejection

This code signifies the body's immune system recognizing a transplanted skin graft from a different individual (allograft) as foreign and mounting an immune response to destroy it. This rejection can manifest in various ways, from mild inflammation to complete graft necrosis, compromising the success of the transplant.

Apply this code when documentation clearly indicates the patient is experiencing an immunological rejection of a skin allograft. This includes acute or chronic rejection episodes, regardless of the severity or the specific site of the skin graft. It should be used when the primary reason for the encounter is the management or evaluation of this rejection.

• Ensure the documentation specifies "allograft" to differentiate from autograft or xenograft rejection.
• Do not use for complications like infection or mechanical failure of the graft; these have separate codes.
• Consider an additional code for the specific manifestation of the rejection, if clinically relevant and documented.
