Leakage of carotid arterial graft (bypass), subs encntr

This code signifies a complication where a carotid arterial graft, previously implanted to bypass a narrowed or blocked carotid artery, is leaking. This leakage indicates a failure of the graft integrity, potentially leading to blood loss or reduced blood flow to the brain.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a known leakage from a carotid bypass graft. This includes situations where the patient is admitted for repair of the leak, or for diagnostic work-up to confirm the leakage during a subsequent encounter.

• Ensure documentation clearly specifies "leakage" of the carotid graft, not just a general complication.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always review operative reports and imaging studies to confirm the location and nature of the graft complication.
