What is AKI in medical terms?

Acute kidney injury (AKI) is where your kidneys suddenly stop working properly. It can range from minor loss of kidney function to complete kidney failure. AKI normally happens as a complication of another serious illness.

Is acute kidney injury the same as kidney failure?

Acute kidney injury (AKI), also known as acute renal failure (ARF), is a sudden episode of kidney failure or kidney damage that happens within a few hours or a few days.

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 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. This is typically caused by diminished/reduced renal arterial perfusion. Intravascular coagulation, vascular spasm and microvascular injury are ...

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.

Is ATN a PDX?

The creatinine on discharge had improved to 1.1 which is the patient’s baseline. In this case, ATN would NOT be appropriate as the PDX since it is related to sepsis. There are specific guidelines that state to code the systemic infection first and then any organ dysfunction associated with the diagnosis.

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. Several physicians still use “acute renal insufficiency” as a diagnosis and oftentimes they mean AKI. Coders see this often with one physician documenting injury or failure and another documenting insufficiency.

Is AKI reversible?

AKI is most common in people that are already sick or in the hospital. AKI does require intensive treatment and it is mostly reversible if you are in good health and discovered early in the presentation. However, for those patients that this is not found early or have other comorbid conditions, those patients may develop lasting damage after ...

What is code also?

Code Also. Code Also Help. A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter. associated underlying condition. Type 1 Excludes.

What is a type 1 exclude note?

A type 1 excludes note indicates that the code excluded should never be used at the same time as N17. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

What is acute renal failure?

Acute renal/kidney failure or injury is a sudden, severe onset of inadequate kidney function. There are many causes of acute renal/kidney failure/injury, however, when due to dehydration, it is because there is decreased renal blood flow from lower blood pressure because of the dehydration. This starts causing functioning problems with the kidney.

What are the symptoms of a kidney infection?

Symptoms include oliguria, edema resulting from salt and water overload, nausea and vomiting, lethargy from the toxic effects of the waste products building up, hydronephrosis and at times metabolic acidosis. BUN and creatinine will be significantly elevated.

What happens when you get dehydrated?

Once dehydration sets in, it can quickly start to affect many body organs. One of these is the kidneys. This can lead to acute renal/kidney failure/injury.

What is KDIGO treatment?

KDIGO (Kidney Disease: Improving Global Outcomes group ) Treatment involves treating the underlying cause, and if due to dehydration, that means treating the dehydration with fluids. Renal function (BUN, creatinine) would be followed and monitored along with fluid intake.

What is the cause of dehydration?

Dehydration results from excessive water loss from body tissues. Etiologies include but are not limited to extensive vomiting, diarrhea, gastroenteritis, renal or adrenal disease, diabetes mellitus, diuretic therapy, or having an ileostomy or colostomy.

What is the best practice for a coder?

Best practice is for the coder to look at both conditions documented clinically and carefully, remembering that every patient is different. Review the admission order to see if the physician is indicating the exact reason for admission.
