Mech compl of surgically created AV shunt, sequela

This code signifies a long-term or late-occurring mechanical issue with an arteriovenous (AV) shunt that was surgically created, excluding specific complications like infection or hemorrhage. These complications arise after the initial healing phase and represent residual effects or chronic problems stemming from the shunt's presence or previous acute complications.

Use this code for patients presenting with chronic or residual mechanical problems related to a surgically created AV shunt, such as persistent stenosis, occlusion, aneurysm formation, or pseudoaneurysm, that are not acute events. It is appropriate when the complication's effects are still being experienced or treated long after the initial surgical procedure and any acute phase of the complication has passed.

• This seventh character 'S' indicates a sequela, meaning the code should be used for complications or conditions that are the late effects of an earlier mechanical complication.
• Ensure documentation clearly links the current chronic condition to a previous mechanical complication of the AV shunt.
• Do not use for acute or initial presentations of mechanical complications; those would typically use the 'A' or 'D' seventh character.
