Pyuria

This code indicates the presence of white blood cells (leukocytes) in the urine, signifying inflammation or infection within the urinary tract. It is a laboratory finding often associated with conditions like urinary tract infections (UTIs), kidney infections, or other inflammatory processes affecting the genitourinary system.

Use this code when laboratory urinalysis results confirm the presence of pyuria, typically indicated by a positive leukocyte esterase test or microscopic examination showing white blood cells. It is commonly used as a diagnostic finding supporting a suspected UTI or other urinary tract inflammation. Documentation should clearly state the finding of pyuria from a lab report.

• Do not code pyuria as a definitive diagnosis of a UTI; it is a symptom. Code the underlying condition if known.
• If the cause of pyuria is unknown, this code can be used as a primary diagnosis.
• Distinguish from hematuria (blood in urine); these are distinct findings and coded separately.
