Anuria and oliguria
Chapter 18:Symptoms, signs and abnormal clinical findings
ICD-10 R34 is a billable code used to indicate a diagnosis of anuria and oliguria.
Anuria and oliguria are clinical conditions characterized by significantly reduced urine output. Anuria is defined as the absence of urine production (less than 100 mL per day), while oliguria refers to a decrease in urine output to less than 400 mL per day. These conditions can arise from various underlying causes, including acute kidney injury, chronic kidney disease, dehydration, urinary obstruction, and severe infections. Understanding the etiology of anuria and oliguria is crucial for appropriate management and treatment, as these conditions can indicate serious renal impairment or systemic issues requiring immediate medical attention.

R34 includes conditions of anuria and oliguria, which may result from acute kidney injury, chronic kidney disease, dehydration, urinary obstruction, or severe systemic infections.
R34 codes should be used when a patient presents with significantly reduced urine output, specifically when urine output is less than 400 mL per day for oliguria or less than 100 mL per day for anuria.
Documentation should include precise measurements of urine output, clinical findings, the underlying cause of the condition, and any relevant laboratory results to support the diagnosis.
