Biliuria

This code indicates the presence of bilirubin in the urine, a condition often signaling underlying liver dysfunction or biliary obstruction. Bilirubin is a yellow pigment formed from the breakdown of red blood cells, and its presence in urine (biliuria) is abnormal.

Use this code when laboratory tests confirm the presence of bilirubin in a urine sample. This finding is typically associated with conditions like hepatitis, cirrhosis, gallstones, or other disorders affecting bile production or flow. Documentation should clearly state "biliuria" or "bilirubin in urine."

• Always code the underlying condition causing the biliuria first, as biliuria is a symptom.
• Do not confuse with urobilinogen in urine, which is a different metabolic product and indicates different clinical scenarios.
• Ensure the medical record explicitly documents the finding of bilirubin in the urine, not just general abnormal urinalysis.
