Unspecified kidney failure (N19)
The ICD-10 code N19 is used to classify cases of unspecified kidney failure, encompassing a range of kidney dysfunctions where detailed cause or type is not specified. This code covers various kidney failure conditions including chronic and acute forms when exact diagnosis details are unavailable.
Unspecified kidney failure (N19) includes conditions commonly known by several synonyms, such as renal failure syndrome, chronic progressive renal failure, and uremia. It also applies to complications like anemia, neuropathy, and platelet function disorders due to kidney failure. Practitioners may encounter terms like dependence on renal dialysis, benign hypertensive renal disease, and uremic encephalopathy, all of which fall under this code when specific renal failure type is not recorded. Using the ICD-10 code for unspecified kidney failure ensures accurate coding when the nature of kidney impairment is unclear, aiding medical coding professionals in classifying a broad spectrum of renal failure-related conditions without exact specification.
Instructional Notations
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
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 Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Calciphylaxis
Condition of induced systemic hypersensitivity in which tissues respond to appropriate challenging agents with a sudden local calcification.
Hyperphosphatemia
A condition of abnormally high level of PHOSPHATES in the blood, usually significantly above the normal range of 0.84-1.58 mmol per liter of serum.
Phosphates
Inorganic salts of phosphoric acid.
Uremia
A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY. Most uremic toxins are end products of protein or nitrogen CATABOLISM, such as UREA or CREATININE. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.
Uremic Toxins
Biological solutes retained and accumulated due to kidney impairment that contribute to uremia/chronic kidney disease.
