    Nephrotic syndrome

      2016 2017 2018 2019 Non-Billable/Non-Specific Code
    Includes
    • congenital nephrotic syndrome
    • lipoid nephrosis
    Nephrotic syndrome
Approximate Synonyms
  • Congenital nephrotic syndrome
  • Hypoxic nephrosis
  • Nephrotic syndrome
  • Renal anasarca
Clinical Information
  • A collection of symptoms that include severe edema, proteinuria, and hypoalbuminemia; it is indicative of renal dysfunction.
  • A condition characterized by severe proteinuria, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as hypoproteinemia; generalized edema; hypertension; and hyperlipidemias. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.
  • A kidney disease characterized by a high protein level in urine
  • Diseases involving defective kidney glomeruli, characterized by massive proteinuria and lipiduria with varying degrees of edema, hypoalbuminemia, and hyperlipidemia.
  • Nephrotic syndrome: twenty-four hour urine protein > three grams. May be associated with hypoalbuminemia and hypercholesterolemia.
ICD-10-CM N04.9 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):
  • 698 Other kidney and urinary tract diagnoses with mcc
  • 699 Other kidney and urinary tract diagnoses with cc
  • 700 Other kidney and urinary tract diagnoses without cc/mcc
