Breakdown of surgically created AV fistula, init

This code signifies a mechanical failure of an arteriovenous fistula (AVF) that was surgically created for dialysis access. This breakdown refers to a physical issue with the fistula itself, such as a rupture, disconnection, or other structural compromise, rather than an infection or functional problem. The "initial encounter" indicates that the patient is receiving active treatment for this specific complication.

Use this code when a patient presents with a newly identified mechanical failure of their surgically created AVF, requiring immediate medical attention or intervention. This applies to situations where the fistula has physically broken down, leading to loss of access or other acute symptoms. It is appropriate for the initial diagnostic workup and treatment phase of the complication.

• Ensure documentation clearly specifies a mechanical breakdown, not an infectious or functional issue.
• Confirm the encounter is the initial treatment for this specific complication; subsequent encounters would use a different seventh character.
• Verify the AVF was surgically created for dialysis access, differentiating it from other types of fistulas or grafts.
