Left upper quadrant rebound abdominal tenderness

This code signifies the presence of pain upon release of pressure from the left upper quadrant of the abdomen, indicating peritoneal irritation. It is a clinical sign elicited during physical examination, often suggestive of an underlying inflammatory or infectious process within the abdominal cavity.

Assign this code when documentation explicitly states "left upper quadrant rebound tenderness" during a physical examination. This finding is commonly associated with conditions like gastritis, pancreatitis, splenic injury, or diverticulitis affecting the left colon. The physician's assessment and physical exam findings are key supporting documentation.

• Do not use this code if the tenderness is described as direct or localized without the "rebound" characteristic.
• Always sequence this code after the definitive diagnosis, if known, as it represents a symptom.
• Distinguish from R10.11 (upper abdominal tenderness, unspecified site) or R10.821 (right upper quadrant rebound tenderness).
