What are the types of Aki?

Jan 07, 2016 · Q: I have seen documentation of oliguric renal failure and non-oliguric renal failure. What is the difference and does it impact coding? A: We can define acute kidney injury (AKI) in terms of serum creatinine stages but we can also define it in terms of urinary output. Now the term “oliguric renal failure” is one we use where people have AKI but their urine output is less …

What is oliguric acute kidney injury?

Oliguria is defined as a daily urine volume of less than 400 mL and has a worse prognosis. Anuria is defined as a urine output of less than 100 mL/day and, if abrupt in onset, suggests bilateral obstruction or catastrophic injury to both kidneys.

What is acute nontraumatic kidney injury?

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. AKI causes a build-up of waste products in your blood and makes it hard for your kidneys to keep the right balance of fluid in your body.

What is kidney injury?

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. It's not the result of a physical blow to the kidneys, as the name might suggest.

What is acute kidney failure unspecified mean?

Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance.Jul 23, 2020

What does acute kidney injury N17 9 mean?

ICD-10 code N17. 9 for Acute kidney failure, unspecified is a medical classification as listed by WHO under the range - Diseases of the genitourinary system .

What is the difference between anuria and oliguria?

Oliguria is defined as having only 100 mL to 400 mL (3.3 to 13.5 oz) of urine per day and anuria (the most extreme of all of these) is defined as urine production of zero to 100 mL (0 to 3.3 oz) per day. Anuria isn't really a disease itself, but it's a symptom of some other condition.Sep 29, 2021

How does acute kidney injury cause oliguria?

In case fluid corrections are not done, decremental reductions in GFR and RBF will result in acute renal failure (ARF). Renal causes of oliguria arise as a result of tubular damage. As a result of the tubular damage, the kidney loses its normal function i.e., production of urine while excreting the waste metabolites.Aug 4, 2021

What is polyuria and oliguria?

Oliguria is defined as a urine output that is less than 400 mL/24 h or less than 17 mL/h in adults. Anuria is defined as urine output that is less than 100 mL/24 h or 0 mL/12 h. Polyuria is a condition characterized that there is large volumes of urine (at least 3000 mL over 24 h). Many factors affect the urine volume.Aug 27, 2019

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 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 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.

Is it difficult to coding AKI?

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 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 ...

Why should a coder know what criteria to use for AKI?

Coders should know which criteria their facility is using for diagnosing AKI so that they can be sure that the diagnosis given by the physician is clinically validated. There is no one criteria that is mandatory for use. One of the most challenging areas that coders face today is knowing when a query is necessary.

What is better to ask the physician about AKI?

It is better to ask the physician what criteria were used to make the diagnosis of AKI or involve CDI or a physician liaison for help with these. Physician education is needed, and if coders don’t query, then the facilities and physicians will not know that there is a documentation issue.

What is rifle classification?

Does OCG mean there is no clinical indicator?

The statement in the OCG above doesn’t mean that there doesn’t have to be clinical indicators for a disease present at all, only that the physician is not limited to a specific set of clinical criteria he can use to make a diagnosis. There are many “established” criteria for many diseases and AKI is no different.
