Code Description

ICD-10 R34 is a billable code used to indicate a diagnosis of anuria and oliguria.

Key Diagnostic Point:

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.

  • The clinical significance of anuria and oliguria lies in their potential to signal acute or chronic renal failure, necessitating prompt evaluation and intervention. In clinical practice, the identification of these conditions is essential for guiding further diagnostic testing and therapeutic strategies. The usage of the R34 code is appropriate when documenting cases of anuria or oliguria in patient records, ensuring that healthcare providers can accurately communicate the severity of the patient's renal status and facilitate appropriate care pathways.

ICD-10 Improvements

The clinical impact of the R34 code category is significant, as it encompasses conditions that can lead to severe health complications if not addressed promptly. Anuria and oliguria can serve as indicators of acute kidney injury or other serious systemic issues, making their identification crucial for timely intervention. From a population health perspective, understanding the prevalence of these conditions can help healthcare systems develop targeted strategies for prevention and management, particularly in at-risk populations.
Administratively, accurate coding of anuria and oliguria is essential for quality measures and healthcare analytics. It allows for better tracking of renal health trends and can inform resource allocation within healthcare systems. As healthcare continues to focus on value-based care, the implications of accurately documenting and managing these conditions will play a vital role in improving patient outcomes and reducing healthcare costs.

Frequently Asked Questions

What conditions are included in R34?

R34 includes conditions of anuria and oliguria, which may result from acute kidney injury, chronic kidney disease, dehydration, urinary obstruction, or severe systemic infections.

When should I use R34 codes?

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.

What documentation is required for R34?

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.
