Hyperuricosuria

This code signifies an abnormally high concentration of uric acid in the urine. It indicates a metabolic disturbance where the kidneys excrete excessive amounts of uric acid, potentially leading to the formation of kidney stones or other complications.

Use this code when laboratory results confirm elevated urinary uric acid levels, often identified during evaluation for nephrolithiasis, gout, or unexplained renal dysfunction. Documentation should clearly state "hyperuricosuria" or specify elevated 24-hour urine uric acid excretion.

• Do not confuse with hyperuricemia (elevated uric acid in the blood), which is coded separately.
• Always look for specific documentation of urinary uric acid levels, not just serum levels.
• Consider sequencing this code with any associated conditions, such as nephrolithiasis (N20.0) if present.
