Closure Of Kidney-To-Skin Fistula

Maryland rates for HCPCS 50520

Surgery that closes an abnormal tunnel running from the kidney or its collecting funnel out to the skin surface, which leaks urine through the skin. The surgeon exposes the tract, removes the unhealthy tissue lining it, and sews the kidney opening shut so urine drains the normal way again. Such a tunnel usually follows earlier surgery, a drainage tube, injury, or long-standing infection.
