R30-R39: Symptoms and signs involving the urinary system

R31: Unspecified haematuria

Unspecified haematuria is a medical condition that involves the presence of blood in urine. This can occur as a result of several underlying health problems including kidney diseases, urinary tract infections, or bladder conditions. It is not a disease itself, but rather a symptom that indicates possible issues with the urinary system. Often, the blood in the urine may not be visible to the naked eye, and may only be detected with a urine test. However, in other cases, the urine may appear pink, red, or cola-colored. Despite being a symptom, unspecified haematuria is clinically important because it can result in significant patient anxiety, and could be an early sign of serious disorders, such as cancer.
