Chyluria

This code represents the presence of chyle, a milky lymphatic fluid, in the urine. This condition occurs when there is an abnormal communication between the lymphatic system and the urinary tract, leading to the excretion of lymph into the urine.

Use this code when documentation indicates the presence of chyle in the urine, often presenting as milky or cloudy urine. This diagnosis is typically supported by urinalysis findings confirming the presence of chyle or lymphatic fluid.

• Do not code this with B74.- (filarial chyluria), as this is an Excludes1 note.
• Investigate the underlying cause of the chyluria if known and code it as a secondary diagnosis.
• Ensure documentation clearly distinguishes non-filarial chyluria from filarial chyluria to avoid incorrect coding.
