Left lower quadrant rebound abdominal tenderness

This code describes a physical exam finding where a patient experiences pain in the left lower abdomen upon the sudden release of pressure, indicating peritoneal irritation. It is a specific sign often associated with inflammation within the abdominal cavity.

Apply this code when documentation explicitly states "left lower quadrant rebound tenderness" during a physical examination. This finding is commonly observed in conditions such as diverticulitis, left-sided appendicitis (rare), or other inflammatory processes affecting the left lower abdomen.

• Ensure the documentation specifies "rebound" tenderness, not just general tenderness.
• Verify the quadrant is explicitly stated as "left lower quadrant" to avoid laterality errors.
• This code represents a symptom; an underlying definitive diagnosis should be coded first if known.
