Fistula, left hand

This code represents an abnormal, pathological tract or connection between two epithelialized surfaces, or from an epithelialized surface to the exterior of the body, located specifically in the left hand. This can involve communication between an organ and the skin, or between two organs, within the hand structure.

Use this code when documentation clearly indicates the presence of a fistula affecting the left hand. This includes fistulas resulting from infection, trauma, surgery, or inflammatory conditions. The physician's notes should explicitly state the presence and location of the fistula.

• Ensure laterality is clearly documented as "left hand" to support this specific code.
• Investigate the underlying cause of the fistula, if documented, as an additional code may be required to fully describe the patient's condition.
• Differentiate from sinus tracts, which are blind-ended and do not connect two epithelialized surfaces.
