Biliuria

This code indicates the presence of bilirubin in the urine, a condition often signaling underlying hepatobiliary dysfunction or increased bilirubin production. Bilirubinuria typically manifests as dark, tea-colored urine due to the excretion of conjugated (direct) bilirubin.

Assign this code when laboratory urinalysis confirms the presence of bilirubin in the urine. This finding is commonly associated with conditions like obstructive jaundice, hepatitis, or other liver diseases. Documentation should clearly state "bilirubin in urine" or "biliuria" from a lab report or physician's note.

• Do not confuse with urobilinogen in urine; these are distinct findings.
• Always code the underlying condition causing the biliuria, if known and documented, as the primary diagnosis.
• This code is for the presence of bilirubin, not the level or cause.
