I12.9: Hypertensive renal disease without renal failure

Hypertensive renal disease without renal failure (ICD-10 code I12.9) is a condition where the kidneys are damaged due to high blood pressure but not to the point of renal failure. High blood pressure, or hypertension, forces the heart to work harder than usual to pump blood throughout the body, and this extra strain could damage the blood vessels in the kidneys over time. When the kidneys are damaged, they lose their ability to efficiently filter the waste and excess fluids from the body. This condition is often asymptomatic, meaning it does not usually cause noticeable symptoms, especially in the early stages. As the disease progresses, individuals may experience swelling in the hands and feet, frequent urination, lethargy, nausea, and headaches. Over time, if left untreated, it could lead to more serious complications like kidney failure.
