Endocarditis and heart valve disord in dis classd elswhr

This code describes inflammation of the inner lining of the heart (endocardium) and/or structural abnormalities of the heart valves that are secondary manifestations of another underlying disease process. It indicates that the primary disease causing these cardiac issues is classified elsewhere in the ICD-10-CM system.

Apply this code when documentation clearly links endocarditis or a heart valve disorder to a specific underlying systemic disease, and that primary disease has its own distinct ICD-10-CM code. This code is used as a secondary diagnosis, following the code for the primary condition.

• Always sequence the code for the underlying systemic disease first, followed by this code.
• Carefully review the "Excludes1" list to ensure the specific infectious or systemic disease causing the endocardial/valvular involvement is not listed there, as those conditions have their own specific combination codes.
• Ensure documentation explicitly states the causal relationship between the underlying disease and the endocarditis/valve disorder.
