Other transplanted tissue rejection

This code signifies the rejection of any transplanted tissue other than bone marrow, corneal, intestinal, kidney, liver, lung, or pancreas. It indicates an adverse immune response where the recipient's body attacks the transplanted tissue, leading to its dysfunction or failure. This rejection can be acute or chronic and may manifest with various signs and symptoms depending on the specific tissue involved.

Use this code when documenting the rejection of transplanted tissues such as skin grafts, heart valves, vascular grafts, or other specified tissues not covered by more specific rejection codes. This applies when the physician explicitly diagnoses rejection of the transplanted tissue. It is appropriate for both initial and subsequent encounters related to the management of this rejection.

• Always code the specific type of transplanted tissue rejection if a more precise code is available.
• Ensure documentation clearly states "rejection" of the transplanted tissue.
• Consider an additional code to specify the type of transplanted tissue, if known and not implicitly covered by the rejection code.
