What This Code Means

A bacterial, viral, fungal, or other infection develops in or around the transplanted liver.

Coding Tips

•Code the specific infectious organism separately if documented (e.g., hepatitis C, bacterial cholangitis)
•Post-transplant infections are common; ensure the infection is directly related to the transplanted organ

Clinical Significance

Liver transplant infection in immunosuppressed patients can rapidly progress to sepsis and graft failure, particularly with opportunistic pathogens or hepatotropic viruses. These infections require prompt recognition and aggressive treatment while carefully balancing antimicrobial therapy with the need to maintain adequate immunosuppression to prevent rejection.

Documentation Requirements

✓History of liver transplant with transplant date
✓Type and location of infection (hepatic, biliary, systemic)
✓Causative organism identification and sensitivities
✓Clinical presentation and severity assessment
✓Laboratory results including cultures and liver function tests
✓Antimicrobial therapy and treatment response
✓Adjustments to immunosuppressive medications
✓Infectious disease and hepatology consultations

Use Additional Code

code to identify infection, such as:
Cytomegalovirus (CMV) infection (B25.-)
