Leakage of surgically created arteriovenous shunt, subs

This code signifies a complication where an artificial connection between an artery and a vein, typically created for hemodialysis access, is leaking. This leakage occurs after the initial treatment of the complication, indicating ongoing management or follow-up care.

Use this code when a patient presents for evaluation or treatment of a leaking arteriovenous shunt, and this is not the initial encounter for the complication. This applies to situations where the patient is returning for repeat procedures, medication adjustments, or monitoring related to the shunt leakage.

• Requires an additional code to specify the underlying condition necessitating the shunt (e.g., end-stage renal disease).
• Distinguish from initial encounters for shunt leakage, which would use the "A" or "D" seventh character.
• Ensure documentation clearly indicates the "subsequent encounter" nature of the visit for this specific complication.
