Mech compl of surgically created arteriovenous fistula, subs

This code signifies a mechanical issue, other than infection or thrombosis, affecting a surgically created arteriovenous fistula (AVF) that is being addressed during a follow-up visit. This could include problems like aneurysm formation, stenosis, or hemorrhage related to the fistula itself.

Apply this code when a patient presents for ongoing management or treatment of a mechanical complication of their AVF, such as a pseudoaneurysm, venous hypertension, or steal syndrome, after the initial treatment of the complication has already occurred. This code is appropriate for subsequent encounters where the patient is still receiving active treatment for the complication.

• Ensure documentation specifies the type of mechanical complication (e.g., stenosis, aneurysm) and that it is not infection or thrombosis.
• Confirm the encounter is for follow-up care or ongoing treatment of the complication, not the initial treatment.
• Verify the AVF was surgically created, as opposed to congenital or traumatic.
