Chronic kidney failure is a condition where the kidneys' ability to filter waste from the bloodstream becomes worse over time, generally over a period of years. Acute kidney failure is the sudden loss of this important ability. If your kidneys have experienced a direct injury or an obstruction, you are at risk.
Acute renal failure (ARF) can be divided into three main types: perennial, renal, and postrenal.
According to KDIGO, acute renal failure can be diagnosed if any one of the following is present: An increase in SCr by 0.3 mg/dL or more within 48 hours. An increase in SCr of at least 150 percent within a seven-day period. A urine volume of less than 0.5 ml/kg/h over a six-hour period.
In this case, it is appropriate to assign a code for both the acute renal failure (584.9) and chronic renal failure (585.9).
There are 4 well-defined stages of acute renal failure: onset, oliguric-anuric, diuretic, and convalescent. Whether patients go through all 4 and how long each stage lasts depends on the cause of acute renal failure and its severity.
Prerenal acute renal failure is characterized by diminished renal blood flow (60 to 70 percent of cases). In intrinsic acute renal failure, there is damage to the renal parenchyma (25 to 40 percent of cases). Postrenal acute renal failure occurs because of urinary tract obstruction (5 to 10 percent of cases).
Causes of kidney failure. Kidney failure can be the result of several conditions or causes. According to the National Kidney Foundation, the two most common causes are high blood pressure and diabetes. People who are most at risk usually have one or more of the following.
Diabetes is the most common cause of kidney disease. Both type 1 and type 2 diabetes. But also heart disease and obesity can contribute to the damage that causes kidneys to fail.
ICD-10-CM code N28. 9 is reported to capture the acute renal insufficiency.
ICD-10 | Cerebral infarction, unspecified (I63. 9)
The ICD-10-CM code for Chronic Kidney Disease (CKD) Stage 3 (N18. 3) has been revised for Fiscal Year 2021.
