Persistent postprocedural fistula, sequela

This code signifies a chronic or long-standing abnormal connection between two organs, vessels, or other non-anatomical spaces that developed as a complication of a previous medical procedure. The fistula has persisted beyond the typical healing period and is now considered a lasting consequence of the intervention.

Apply this code when documentation clearly indicates a fistula that originated from a surgical or other invasive procedure and is still present and causing symptoms or requiring ongoing management. This includes scenarios where a patient presents for treatment of a fistula that was previously identified as postprocedural and has not resolved.

• Ensure documentation specifies the fistula is "persistent" or "chronic" and directly links its origin to a prior procedure.
• Remember the "S" seventh character indicates a sequela, meaning the patient is receiving care for the late effects of the initial complication.
• Always code the specific type of fistula (e.g., enterocutaneous, vesicovaginal) if known and documented, in addition to this code.
