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 N28.0.

    Other disorders of kidney and ureter

    Type 2 Excludes
    • disorders of kidney and ureter with urolithiasis (N20-N23)
    Other disorders of kidney and ureter
Approximate Synonyms
  • Acute scleroderma renal crisis
  • Occlusion due to renal artery embolism
  • Renal artery embolism with occlusion
  • Renal infarction
  • Renal ischemia
  • Renal vascular disorder
  • Scleroderma renal crisis
  • Thromboembolism of renal arteries
  • Thromboembolism of renal artery
Clinical Information
  • Blocking or clogging of the renal artery, which is the branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters.
  • Narrowing or occlusion of the renal artery or arteries. It is due usually to atherosclerosis; fibromuscular dysplasia; thrombosis; embolism, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (hypertension, renovascular).
