What This Code Means

An infection develops in or around a transplanted heart, potentially compromising its function.

Coding Tips

•Identify and code the specific infectious agent separately when documented
•Note whether infection affects the myocardium, valves, or surrounding tissues

Clinical Significance

Heart transplant infection in immunosuppressed patients carries high morbidity and mortality risk, particularly with opportunistic pathogens that can cause rapid clinical deterioration. These infections require prompt diagnosis, aggressive antimicrobial therapy, and careful balance between treating infection and maintaining adequate immunosuppression.

Documentation Requirements

✓History of heart transplant with transplant date
✓Type and location of infection (endocarditis, mediastinitis, systemic)
✓Causative organism and antimicrobial sensitivities
✓Clinical presentation and severity of infection
✓Diagnostic studies including cultures, imaging, and tissue sampling
✓Antimicrobial therapy and treatment response
✓Adjustments to immunosuppressive medications
✓Infectious disease and transplant team consultations
