Traumatic anuria, initial encounter

This code signifies the complete cessation of urine production that occurs as a direct result of a traumatic injury. It indicates a severe and acute kidney dysfunction stemming from physical trauma, rather than a pre-existing medical condition.

Use this code for patients presenting with anuria immediately following an accident, blunt force trauma, crush injury, or penetrating injury where the anuria is clearly attributable to the traumatic event. This code is appropriate for the initial treatment period of such an injury.

• Ensure documentation clearly links the anuria to the traumatic event.
• Always code the underlying traumatic injury first, followed by this code.
• This "initial encounter" character (A) is used as long as the patient is receiving active treatment for the anuria.
