Breakdown of surgically created AV shunt, sequela

This code signifies a mechanical failure of an arteriovenous (AV) shunt that was surgically created, occurring as a late effect or complication. This breakdown can involve issues such as thrombosis, stenosis, or other structural problems that impair the shunt's function. It specifically refers to the physical malfunction of the device itself, not an infection or other non-mechanical complication.

Use this code when a patient presents with a malfunctioning AV shunt, previously placed for hemodialysis access, due to a mechanical issue. This includes scenarios where the shunt has clotted, narrowed, or otherwise failed structurally, requiring intervention such as thrombectomy, angioplasty, or revision. It is appropriate for follow-up encounters related to the long-term mechanical integrity of the shunt.

• Always use this code as a secondary diagnosis, with a primary code indicating the reason for the encounter (e.g., end-stage renal disease, encounter for follow-up care).
• Ensure documentation clearly specifies a mechanical breakdown of the surgically created AV shunt.
• The "S" in the seventh character indicates a sequela, meaning this is for complications or conditions arising as a direct result of the initial breakdown, even if the initial breakdown occurred in the past.
