Leakage of surgically created arteriovenous fistula, sequela

This code signifies a long-term complication where an arteriovenous (AV) fistula, surgically created for hemodialysis access, develops a persistent or recurring leak. This leakage can manifest as blood or fluid extravasation from the fistula site, indicating a structural integrity issue that arose from the initial surgical procedure. It represents a chronic or residual effect of the original fistula creation.

Use this code when documenting a patient presenting with ongoing or late-onset leakage from a previously established AV fistula. This applies to situations where the leakage is not an acute, immediate post-operative complication but rather a sequela that has developed over time. It is appropriate for follow-up encounters addressing the management of this chronic leakage.

• Assign this code as a secondary diagnosis when the primary reason for the encounter is the management of the leakage.
• Ensure documentation clearly states the leakage is a sequela or chronic complication, not an acute post-operative event.
• Consider additional codes for any associated complications, such as infection or hematoma, if present.
