N17: Acute renal failure

N17.8: Other acute renal failure

Other acute renal failure, coded as N17.8 in the ICD-10 WHO 2016 classification, signifies a medical condition where the kidneys abruptly lose their ability to eliminate excess salts, fluids, and waste materials from the blood. This event can occur over a few hours or days, leading to a rapid buildup of substances within the body – which can be life-threatening. The symptoms often include decreased urine output, fluid retention causing swelling in the legs, ankles or feet, unexplained shortness of breath, excessive drowsiness or fatigue, and persistent nausea. It primarily affects the renal system but can have implications on other body systems as well. Numerous conditions can cause this, such as severe infections, certain medications, blood flow disruptions to the kidneys, and urinary blockages. The progression of this disease is variable and largely depends on the cause and the individual's overall health.
