N17-N19 Acute kidney failure and chronic kidney ...
Chronic renal failure is a condition involving a decrease in the kidneys' ability to filter waste and fluid from the blood. It is chronic, meaning that the condition develops over a long period of time and is not reversible. The condition is also commonly known as chronic kidney disease (CKD).
It is basically the end stage of chronic renal disease, which means the patient often requires dialysis treatment. On the other hand, acute renal insufficiency develops quickly within hours and days as a complication of serious illness, such as a lack of oxygen or blood poisoning.

Chronic kidney failure or chronic renal failure signifies loss of kidney function that occurs over a prolonged course of time as opposed to acute renal failure.
Renal insufficiency is poor function of the kidneys that may be due to a reduction in blood-flow to the kidneys caused by renal artery disease. Normally, the kidneys regulate body fluid and blood pressure, as well as regulate blood chemistry and remove organic waste.
In primary care, acute-on-chronic kidney disease is often caused by hypovolaemia due to an episode of concurrent illness, e.g. upper or lower respiratory tract infection, urinary tract infection, sepsis or gastrointestinal illness.
Acute kidney failure can occur when: You have a condition that slows blood flow to your kidneys. You experience direct damage to your kidneys. Your kidneys' urine drainage tubes (ureters) become blocked and wastes can't leave your body through your urine.
ICD-10-CM code N28. 9 is reported to capture the acute renal insufficiency.
