Left flank tenderness

This code signifies the presence of pain or discomfort upon palpation of the left flank region of the abdomen. It indicates a symptom rather than a definitive diagnosis, often prompting further investigation into its underlying cause.

Apply this code when the patient's medical record explicitly documents tenderness localized to the left flank. This symptom may be associated with conditions affecting the left kidney, spleen, descending colon, or musculoskeletal structures in that area.

• Always code the definitive diagnosis if known and documented, as this is a symptom code.
• Distinguish from generalized abdominal pain or tenderness in other specific quadrants.
• Ensure documentation specifies "left flank" to avoid confusion with unspecified flank tenderness (R10.8A0) or right flank tenderness (R10.8A1).
