Traumatic anuria

This code signifies the complete cessation of urine production resulting from a physical injury. It indicates a severe and acute kidney dysfunction directly attributable to trauma, rather than a pre-existing renal condition or other medical causes.

Apply this code when documentation clearly links anuria to a traumatic event, such as a crush injury, severe blunt abdominal trauma, or penetrating injury affecting the kidneys or urinary tract. Supporting documentation should include details of the trauma, clinical findings of anuria, and diagnostic evidence ruling out non-traumatic etiologies.

• Always code the underlying traumatic injury first, followed by this code as a secondary diagnosis.
• Differentiate from acute kidney injury (AKI) due to non-traumatic causes; this code specifically requires a traumatic origin.
• Ensure documentation specifies "anuria" (absence of urine) rather than "oliguria" (scanty urine production).
