Liver transplant rejection

This code signifies the body's immune response against a transplanted liver, leading to its dysfunction. It indicates that the recipient's immune system is attacking the donor organ, which can manifest in various degrees of severity and impact liver function.

Apply this code when a patient who has undergone a liver transplant is diagnosed with rejection, confirmed by biopsy, imaging, or clinical signs and symptoms. This includes both acute and chronic rejection episodes requiring medical intervention.

• Always code the specific type of liver transplant rejection if known (e.g., acute, chronic) using more specific codes if available.
• Ensure documentation supports the diagnosis of rejection, including diagnostic test results and physician notes.
• Do not use this code for complications of liver transplant that are not specifically rejection, such as infection or vascular complications.
