Bacteremia with Endocarditis of Cardiac Valve Prosthesis
A patient was diagnosed with streptococcus viridans bacteremia and endocarditis of a transplanted aortic valve. Codes T82.6XXA, Infection and inflammatory reaction due to cardiac valve prosthesis, initial encounter, and I33.0, Acute and subacute infective endocarditis, were assigned to capture endocarditis of the cardiac valve prosthesis. Code B95.4, Other streptococcus as the cause of diseases classified elsewhere, was assigned to capture the specified bacteria (streptococcus viridans). Is it appropriate to assign a separate code for the bacteremia? ...

Article Overview
This short coding article discusses how to approach diagnosis coding when bacteremia occurs together with infective endocarditis involving a cardiac valve prosthesis. It is aimed at medical coders and billing staff looking for guidance on diagnosis selection, sequencing context, and whether an additional bloodstream-infection code is appropriate in this scenario. The article also references the supporting organism code and highlights a specific code that should not be assigned.
Why This Topic Matters
These scenarios are common sources of coding uncertainty because multiple related diagnoses and etiologic organism information may be present in one record. Understanding the article helps coders distinguish the principal infection context from related documentation and avoid improper code assignment.
What You Will Learn
- How the article frames bacteremia in relation to endocarditis involving a prosthetic valve.
- What kinds of diagnosis coding considerations are raised when an infective organism is documented.
- Why the article flags a code that should not be assigned in this case.
- How to interpret the scope of the question without relying on a detailed clinical example.
