Chronic kidney disease (CKD) N18-

Use Additional

  • code to identify kidney transplant status, if applicable, (Z94.0)

Code First

  • any associated:
  • diabetic chronic kidney disease (E08.22, E09.22, E10.22, E11.22, E13.22)
  • hypertensive chronic kidney disease (I12.-, I13.-)

Clinical Information

  • A disorder characterized by gradual and usually permanent loss of kidney function resulting in renal failure.
  • An irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body’s electrolyte composition and acid-base balance. (from msh98)
  • Chronic, irreversible renal failure.
  • Gradual and usually permanent loss of kidney function resulting in renal failure. Causes include diabetes, hypertension, and glomerulonephritis.
  • Impairment of the renal function due to chronic kidney damage.
  • Irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body’s electrolyte composition and acid-base balance.
  • The end-stage of chronic renal insufficiency. It is characterized by the severe irreversible kidney damage (as measured by the level of proteinuria) and the reduction in glomerular filtration rate to less than 15 ml per min (kidney foundation: kidney disease outcome quality initiative, 2002). These patients generally require hemodialysis or kidney transplantation.
  • You have two kidneys, each about the size of your fist. Their main job is to filter wastes and excess water out of your blood to make urine. They also keep the body’s chemical balance, help control blood pressure, and make hormones.chronic kidney disease (ckd) means that your kidneys are damaged and can’t filter blood as they should. This damage can cause wastes to build up in your body. It can also cause other problems that can harm your health. Diabetes and high blood pressure are the most common causes of ckd.treatment may include medicines to lower blood pressure, control blood glucose, and lower blood cholesterol. Ckd can get worse over time. Ckd may lead to kidney failure. The only treatment options for kidney failure are dialysis or a kidney transplantation.you can take steps to keep your kidneys healthier longer:
    • choose foods with less salt (sodium)
    • keep your blood pressure below 130/80
    • keep your blood glucose in the target range, if you have diabetes
