What is ATN in kidneys?

ATN occurs when there is damage to the kidney tubule cells. These are the cells that reabsorb fluid and minerals in the kidney from urine as it is forming. When this occurs, there is a lack of oxygen reaching the cells of your kidneys. N17.1—Acute kidney failure with acute cortical necrosis.

What is acute medullary necrosis?

This is caused by infarction involving the medulla and referred to as necrotizing papillitis. N17.8—Other acute kidney failure.

What is ATN in medical terms?

Other terms that may be used to describe ATN could be renal tubular necrosis or tubular necrosis. These are terms that should be searched for when AKI is documented to see if there could be further specificity in code assignment. ATN occurs when there is damage to the kidney tubule cells.

What causes acute cortical necrosis?

Other terms that may be used to describe acute cortical necrosis can be cortical necrosis and renal cortical necrosis. This is a rare cause of AKI and is due to ischemic necrosis of the renal cortex.

What is AKI in medical terms?

The terminology “acute kidney injury (AKI)” has largely replaced the terminology of “acute renal failure (ARF)” over the past few years. AKI is an abrupt decrease in kidney function. The kidneys become unable to filter waste products from the blood. This allows accumulation of dangerous levels of waste, and the chemical makeup ...

What are the phases of AKI?

AKI has four phases: 1 Onset phase: When the kidney injury occurs. Triggering events can be blood loss, fluid loss, or burns to name a few. This last hours to days. In this phase, the renal blood flow is 25% of normal, the tissue oxygenation is 25% of normal and the urine output is below 0.5 mL/kg hour. 2 Oliguric (anuric) phase: When the urine output decreases from renal tubule damage. Urine output is below 100 to 400 mL/day. There is an increase in blood urea nitrogen (BUN) and creatinine levels. There is electrolyte disturbance, fluid overload and acidosis due to the inability of the kidneys to excrete water. This can last for many days and oftentimes does require initiation of dialysis. 3 Diuretic phase: When the kidneys try to heal and the urine output increases but renal tubule scarring and damage occur. This phase occurs when the cause of the AKI is treated and corrected. Daily urine output is above 400 mL/day. There is renal edema and tubule scarring as well as an increased glomerular filtration rate (GFR). This can last for many days and typically does not require dialysis. 4 Recover phase: Renal tubular edema resolves and the renal function improves as the renal edema is decreased. There is normalization of electrolyte balance and fluid. Typically the return of the GFR will improve to within 70% to 80% of normal. This phase may last weeks, months or up to a year.

How long does renal tubular edema last?

There is renal edema and tubule scarring as well as an increased glomerular filtration rate (GFR). This can last for many days and typically does not require dialysis. Recover phase: Renal tubular edema resolves and the renal function improves as the renal edema is decreased.

Why does acidosis last for days?

There is electrolyte disturbance, fluid overload and acidosis due to the inability of the kidneys to excrete water. This can last for many days and oftentimes does require initiation of dialysis. Diuretic phase: When the kidneys try to heal and the urine output increases but renal tubule scarring and damage occur.

Why do kidneys help balance water?

This allows accumulation of dangerous levels of waste, and the chemical makeup of your blood gets out of balance. The kidneys are responsible for removing waste products to help balance water, salt and other minerals/electrolytes. When this stops these build up and can be deadly.

Is it difficult to coding AKI?

Coding the diagnosis of AKI is difficult since there is incomplete and contradictory documentation within many of the hospital records.
