2020 ICD-10-CM Diagnosis Code N17

Acute kidney failure

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • N17 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM N17 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of N17 - other international versions of ICD-10 N17 may differ.

A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.

Type 1 Excludes
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 N17. 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.

    Acute kidney failure and chronic kidney disease
Clinical Information
  • A disorder characterized by the acute loss of renal function and is traditionally classified as pre-renal (low blood flow into kidney), renal (kidney damage) and post-renal causes (ureteral or bladder outflow obstruction).
  • Clinical syndrome characterized by a sudden decrease in glomerular filtration rate, usually associated with oliguria and always associated with biochemical consequences of the reduction in glomerular filtration rate such as a rise in blood urea nitrogen (bun) and serum creatinine concentrations.
  • Sudden and sustained deterioration of the kidney function characterized by decreased glomerular filtration rate, increased serum creatinine or oliguria.
