Breakdown (mechanical) of aortic (bifurcation) graft, subs

This code signifies a mechanical failure or malfunction of an aortic bifurcation graft that was previously implanted to replace a segment of the aorta. This breakdown is not due to infection or other biological processes, but rather a structural issue with the graft itself. The "subsequent encounter" indicates that the patient is receiving routine care, follow-up, or treatment for the complication after the initial treatment of the breakdown.

Use this code for patients presenting for follow-up appointments, medication adjustments, or non-surgical management related to a previously diagnosed mechanical breakdown of an aortic bifurcation graft. This includes scenarios where the patient is being monitored for the graft issue or receiving conservative treatment. Do not use for the initial diagnosis or active surgical intervention for the breakdown.

• Ensure documentation clearly states "mechanical breakdown" and specifies an "aortic bifurcation graft."
• Verify the encounter type is "subsequent" to align with the 7th character 'D'.
• Code any associated symptoms or complications separately if they are not inherent to the graft breakdown itself.
