Fistula, left wrist

This code signifies an abnormal, permanent passageway or tract that has formed in the left wrist. This fistula can connect two organs, a blood vessel and another structure, or an internal organ to the skin surface, allowing for the passage of fluids or secretions.

Apply this code when documentation clearly indicates the presence of a fistula specifically located in the patient's left wrist. This typically arises from infection, trauma, surgery, or inflammatory conditions. Documentation should specify the anatomical location as the left wrist.

• Ensure the documentation specifies "fistula" and not merely a sinus tract, which is a blind-ended tract.
• Always confirm the laterality; this code is specific to the left wrist.
• Look for underlying causes of the fistula, as these may require additional coding.
