Code Description

ICD-10 I12.9 is a billable code used to indicate a diagnosis of hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease.

Key Diagnostic Point:

Hypertensive chronic kidney disease with stage 1 chronic kidney disease (CKD) indicates that the kidneys are mildly impaired, with a glomerular filtration rate (GFR) of 90 or higher. This stage often presents no symptoms, but it is crucial to manage hypertension to prevent progression. Regular monitoring and lifestyle modifications, such as diet and exercise, are essential. Patients may be prescribed antihypertensive medications to maintain optimal blood pressure levels. Early intervention can significantly reduce the risk of advancing to more severe stages of kidney disease.
