Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as N19. 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.

Clinical Information
  • A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of renal insufficiency. Most uremic toxins are end products of protein or nitrogen catabolism, such as urea or creatinine. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.
  • A condition in which the kidneys stop working and are not able to remove waste and extra water from the blood or keep body chemicals in balance. Acute or severe renal failure happens suddenly (for example, after an injury) and may be treated and cured. Chronic renal failure develops over many years, may be caused by conditions like high blood pressure or diabetes, and cannot be cured. Chronic renal failure may lead to total and long-lasting renal failure, called end-stage renal disease (esrd). A person in esrd needs dialysis (the process of cleaning the blood by passing it through a membrane or filter) or a kidney transplant.
  • A severe irreversible decline in the ability of kidneys to remove wastes, concentrate urine, and maintain electrolyte balance; blood pressure; and calcium metabolism.
  • Acute or chronic condition, characterized by the inability of the kidneys to adequately filter the blood substances, resulting in uremia and electrolyte imbalances. Acute renal failure is usually associated with oliguria or anuria, hyperkalemia, and pulmonary edema. Chronic renal failure is irreversible and requires hemodialysis.
  • Excess in the blood of urea, creatinine and other nitrogenous end products of protein and aminoacid metabolism; also, the constellation of signs and symptoms of chronic renal failure.
  • Healthy kidneys clean your blood by removing excess fluid, minerals and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure.if your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of healthcare providers, family and friends, most people with kidney failure can lead full and active lives.
  • Inability of a kidney to excrete metabolites at normal plasma levels under conditions of normal loading or inability to retain electrolytes under conditions of normal intake.
