Ogilvie syndrome

This code signifies acute colonic pseudo-obstruction, a rare condition characterized by massive dilation of the colon without any mechanical obstruction. It results from a disruption in the autonomic nervous system's control over colonic motility, leading to functional ileus.

Assign this code when documentation explicitly states a diagnosis of Ogilvie syndrome or acute colonic pseudo-obstruction. This typically occurs in patients with severe underlying medical conditions, recent surgery, trauma, or certain medications, presenting with abdominal distension, pain, and absent bowel sounds.

• Ensure documentation clearly distinguishes Ogilvie syndrome from mechanical bowel obstruction, which would be coded differently.
• Look for associated underlying conditions or precipitating factors, which may require additional codes.
• Do not confuse with paralytic ileus (K56.0) unless the documentation specifically identifies it as Ogilvie syndrome.
