Fistula, right wrist

This code signifies the presence of an abnormal, pathological tract or opening connecting two epithelialized surfaces, or an epithelialized surface and an internal organ, specifically located in the right wrist. This tract allows for the passage of fluids or secretions that would not normally occur.

This code is appropriate when documentation clearly indicates a fistula affecting the right wrist joint or surrounding soft tissues. This may include fistulas resulting from infection, trauma, surgery, or inflammatory conditions. Documentation should specify the anatomical location as the right wrist.

• Ensure documentation specifies "right wrist" to differentiate from other wrist locations (left, unspecified).
• Investigate the underlying cause of the fistula, if documented, as an additional code may be required to fully describe the patient's condition.
• Do not confuse with sinus tracts, which are blind-ended and do not connect two epithelialized surfaces.
