Unspecified kidney failure (N19)

Browse all the diagnosis codes used for unspecified kidney failure (n19). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

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.
