What is the highest category level for hypertension under control by therapy?

The highest category level for hypertension under control by therapy is classified as I10. This code specifically indicates essential hypertension, which represents a primary condition without the presence of heart disease or any other complications. It encompasses patients whose hypertension is effectively managed through medication or lifestyle changes.

In the ICD-10 coding system, the other codes provided refer to different categories or conditions associated with hypertension. For instance, I11 denotes hypertension with heart disease, indicating the presence of an associated heart condition, which elevates its severity. Similarly, I12 and I13 codes correspond to hypertension related to chronic kidney disease and hypertensive heart AND chronic kidney disease, respectively. These categories indicate a greater level of complexity and associated health risks compared to essential hypertension, which is why I10 remains the highest category for hypertension that is under control.
