Leakage of surgically created arteriovenous fistula, subs

This code signifies a complication where an arteriovenous fistula, surgically created for purposes like hemodialysis access, is leaking. This leakage indicates a failure in the integrity of the fistula, potentially leading to blood loss or compromised function.

Apply this code when a patient presents for follow-up care or treatment related to a previously identified leakage of their surgically created AV fistula. This includes situations where the patient is seen for evaluation, management, or repair of the leaking fistula after the initial treatment phase.

• Ensure documentation clearly specifies "leakage" of the AV fistula, not just general malfunction.
• This "D" encounter character indicates subsequent care after the initial treatment for the leakage.
• Always code the underlying reason for the AV fistula (e.g., end-stage renal disease) as a primary or secondary diagnosis.
