Left lower quadrant pain

This code signifies discomfort or aching localized to the lower left abdominal region. It is a symptom code indicating pain in the area encompassing the left iliac fossa, left flank, and left hypogastric regions.

Apply this code when documentation explicitly states "left lower quadrant pain" as a presenting symptom or a diagnosis. It is appropriate when the underlying cause of the pain is either unknown, not yet definitively diagnosed, or when the pain itself is the primary reason for the encounter.

• Do not use this code if a more specific diagnosis for the pain is established (e.g., diverticulitis, ovarian cyst).
• Always sequence this code after any definitive diagnosis if both are documented and the pain is a symptom of the primary condition.
• Ensure documentation clearly specifies "left" lower quadrant; otherwise, consider R10.30 (unspecified) or R10.33 (periumbilical).
