Flank pain, right side

This code signifies discomfort or aching localized to the right flank region of the torso. It indicates pain experienced on the right side between the lower ribs and the iliac crest, without further specification of its underlying cause.

Apply this code when documentation explicitly states "right flank pain" as a symptom, without a definitive diagnosis for the pain's etiology. It is appropriate for initial encounters or when the physician is still investigating the source of the pain.

• Do not use this code if a more specific diagnosis for the right flank pain (e.g., nephrolithiasis, pyelonephritis) is documented.
• Always sequence this code as a secondary diagnosis if the underlying cause of the pain is known and coded.
• Ensure the medical record clearly specifies "right" flank pain; otherwise, consider using an unspecified flank pain code.
