ICD-10-CM Code N19

Unspecified kidney failure

Version 2020 Billable Code

Valid for Submission

N19 is a billable code used to specify a medical diagnosis of unspecified kidney failure. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code N19 might also be used to specify conditions or terms like absent renal function, acquired platelet function disorder, action myoclonus renal failure syndrome, acute pericarditis secondary to uremia, anemia of renal disease, anemia secondary to renal failure, etc

Short Description:Unspecified kidney failure

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code N19:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Uremia NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • acute kidney failure N17
  • chronic kidney disease N18
  • chronic uremia N18.9
  • extrarenal uremia R39.2
  • prerenal uremia R39.2
  • renal insufficiency acute N28.9
  • uremia of newborn P96.0

Clinical Information

  • KIDNEY FAILURE CHRONIC-. 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.
  • RENAL INSUFFICIENCY-. conditions in which the kidneys perform below the normal level in the ability to remove wastes concentrate urine and maintain electrolyte balance; blood pressure; and calcium metabolism. renal insufficiency can be classified by the degree of kidney damage as measured by the level of proteinuria and reduction in glomerular filtration rate.
  • ACUTE KIDNEY INJURY-. abrupt reduction in kidney function. acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; acute kidney tubular necrosis; and other less severe conditions.

Diagnostic Related Groups

The ICD-10 code N19 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2019 through 09/30/2020.

Information for Patients

Kidney Failure

Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure.

If your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of health care providers, family, and friends, most people with kidney failure can lead full and active lives.
