Leakage of coronary artery bypass graft, subs encntr

This code indicates a complication where a coronary artery bypass graft (CABG) is leaking, and the patient is receiving follow-up care for this specific issue. This leakage can lead to reduced blood flow to the heart muscle or other adverse events.

Apply this code when a patient presents for ongoing treatment, monitoring, or evaluation of a previously identified leakage in their coronary artery bypass graft. This includes situations where the patient is admitted for further diagnostic workup or non-surgical management of the leak.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care for the complication.
• Do not use for initial treatment of the leakage; that would require a "A" for initial encounter.
• Always sequence this code after the primary diagnosis for the underlying cardiac condition, if applicable.
