Question: 1 / 400

Which diagnosis code should be used for unspecified heart failure?

I10

I50.9

The diagnosis code for unspecified heart failure is I50.9. This code is part of the category that describes heart failure but does not specify the type or etiology. In clinical coding, it is crucial to use the most accurate and specific code available; however, when the details of the condition are not provided, I50.9 serves as the appropriate code for unspecified cases.

In this context, other choices represent different conditions or more specific types of heart issues. For instance, I10 pertains to essential hypertension, I50.1 is designated for left ventricular heart failure specifically, and I11.0 is used for heart failure associated with hypertension. None of these codes accurately capture the unspecified nature of the heart failure condition indicated in the question, making I50.9 the correct and most suitable choice.
