Traumatic anuria, sequela

This code signifies a long-term or permanent kidney dysfunction, specifically the complete absence of urine production (anuria), that resulted from a past traumatic injury. It indicates that the anuria is not an acute event but rather a lasting consequence of the initial trauma.

Use this code for patients presenting with chronic anuria directly attributable to a previous physical trauma, such as a severe crush injury, blunt force trauma to the abdomen, or penetrating injury affecting the kidneys. This code is appropriate when the anuria has stabilized as a permanent sequela after the initial acute phase of injury and treatment.

• Always sequence this code after the code for the specific type of anuria (e.g., N17.0 for acute kidney failure with tubular necrosis, if applicable, or other relevant anuria codes).
• Ensure documentation clearly links the current anuria to a past traumatic event and specifies its chronic nature.
• An additional code for the specific type of trauma that caused the anuria should also be reported, if not already documented as resolved.
