When your kidneys stop working suddenly, over a very short period of time (usually two days or less), it is called acute kidney injury (AKI). AKI is sometimes called acute kidney failure or acute renal failure. It is very serious and requires immediate treatment. Unlike kidney failure that results from kidney damage that gets worse slowly, AKI is often reversible if it is found and treated quickly.
If you were healthy before your kidneys suddenly failed and you were treated for AKI right away, your kidneys may work normally or almost normally after your AKI is treated. Some people have lasting kidney damage after AKI. This is called chronic kidney disease, and it could lead to kidney failure if steps are not taken to prevent the kidney damage from getting worse.
Signs and symptoms of acute kidney failure may include decreased urine output (although occasionally urine output remains normal), fluid retention, swelling in your legs or feet, shortness of breath, fatigue, confusion, nausea, weakness, irregular heartbeat, chest pain, pressure, seizures, or a coma in severe cases. Sometimes acute kidney failure causes no signs or symptoms and is detected through lab tests done for another reason.
Treatment for acute kidney failure typically requires a hospital stay. Most people with acute kidney failure are already hospitalized. How long you’ll stay in the hospital depends on the reason for your acute kidney failure and how quickly your kidneys recover. In some cases, you may be able to recover at home. Treatment for acute kidney failure involves identifying the illness or injury that originally damaged your kidneys. Your treatment options depend on what’s causing your kidney failure. Treatments that help prevent complications include treatments to balance the number of fluids in your blood, medications to control blood potassium, medications to restore blood calcium levels, and dialysis to remove toxins from your blood.
The table below includes the most commonly used ICD-10 codes for AKI:
|ICD-10 Chapter||Codes||Code Description|
|14||N17.0||Acute kidney failure with tubular necrosis|
|14||N17.1||Acute kidney failure with acute cortical necrosis|
|14||N17.2||Acute kidney failure with medullary necrosis|
|14||N17.8||Other acute kidney failure|
|14||N17.9||Acute kidney failure, unspecified|
|15||O90.4||Postpartum acute kidney failure|
