Flank pain, bilateral

This code signifies pain experienced on both sides of the torso, specifically in the area between the ribs and the hip, often associated with the kidneys or urinary tract. It indicates a symptom rather than a definitive diagnosis, requiring further investigation into the underlying etiology.

Apply this code when documentation explicitly states bilateral flank pain without a more specific diagnosis established at the time of coding. It is appropriate for initial encounters or when the cause of the pain is still under investigation, such as in cases of suspected nephrolithiasis, pyelonephritis, or musculoskeletal strain.

• Do not use this code if a definitive diagnosis explaining the bilateral flank pain is documented (e.g., bilateral renal calculi).
• Always sequence this code as a secondary diagnosis when a more specific underlying condition is identified and coded.
• Ensure documentation clearly specifies "bilateral" to support the use of this code; otherwise, use codes for unspecified or unilateral flank pain.
