Kidney failure, also known as renal failure or end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. [2]
Generally, diseases outlined within the ICD-10 codes N00-N19, N20.0 within Chapter XIV: Diseases of the genitourinary system should be included in this category. Wikimedia Commons has media related to Kidney diseases .
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
National adaptations of the ICD-10 progressed to incorporate both clinical code (ICD-10-CM) and procedure code (ICD-10-PCS) with the revisions completed in 2003. In 2009, the US Centers for Medicare and Medicaid Services announced that it would begin using ICD-10 on April 1, 2010, with full compliance by all involved parties by 2013. [19]
Patients with nephrotic-range (>3.5 g/day) proteinuria have over a 50% rate of progression to end-stage kidney disease at 10 years. [6] Only 15% of patients with sub-nephrotic ranges of proteinuria progress to end-stage renal failure at 10 years. [6] Initial response to therapy also dictates long-term outcomes.
The diagnosis of retroperitoneal fibrosis cannot be made on the basis of the results of laboratory studies. CT is the best diagnostic modality: [25] a confluent mass surrounding the aorta [6] and common iliac arteries can be seen.
Renal azotemia (acute kidney failure) typically leads to uremia. It is an intrinsic disease of the kidney, generally the result of kidney parenchymal damage. Causes include kidney failure, glomerulonephritis, acute tubular necrosis, or other kidney disease. [3] The BUN:Cr in renal azotemia is less than 15.
Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.
