Breakdown (mechanical) of surgically created AV shunt, subs

This code signifies a mechanical failure of an arteriovenous (AV) shunt that was surgically created, occurring during a subsequent encounter for care. This breakdown could involve issues like a dislodged or fractured component, but not an infection or occlusion due to thrombosis. The patient is receiving active treatment for this specific complication.

Apply this code when a patient presents for follow-up care or treatment of a mechanical problem with their surgically implanted AV shunt, such as a fractured graft or a dislodged connection. This is appropriate when the issue is structural and not related to blood flow blockage or infection. The "D" indicates the patient is still under active treatment for this specific complication.

• Ensure the documentation clearly states a mechanical breakdown of the AV shunt, not a thrombotic or infectious complication.
• Verify that the encounter is for active treatment of the breakdown, justifying the "D" (subsequent encounter) seventh character.
• Distinguish from other AV shunt complications, such as occlusion (T82.85-) or infection (T82.7-).
