Nontraumatic compartment syndrome of abdomen

This code signifies a condition where increased pressure within the abdominal compartment compromises organ perfusion, leading to ischemia and potential organ dysfunction, without a preceding traumatic event. It represents a life-threatening medical emergency requiring prompt recognition and intervention.

Use this code for patients presenting with signs and symptoms of abdominal compartment syndrome (e.g., tense abdomen, oliguria, respiratory distress) where trauma has been ruled out as the cause. Documentation should clearly indicate the diagnosis of nontraumatic abdominal compartment syndrome, often supported by intra-abdominal pressure measurements.

• Differentiate carefully from traumatic abdominal compartment syndrome, which is coded elsewhere.
• Ensure documentation specifies "nontraumatic" to support this specific code.
• Consider sequencing this code as a principal diagnosis if it is the primary reason for admission and treatment.
