Leakage of biological heart valve graft, subs encntr

This code signifies the escape of fluid or blood from a previously implanted biological heart valve, indicating a functional failure of the graft. This leakage can lead to various cardiac complications, including heart failure or hemodynamic instability.

Apply this code when a patient presents for follow-up care, monitoring, or treatment related to a known leakage of their biological heart valve graft. This includes scenarios where the leakage was previously diagnosed and the patient is returning for ongoing management.

• Ensure documentation clearly specifies a "biological" heart valve, not mechanical.
• The "D" seventh character indicates a subsequent encounter, meaning the initial treatment for the leakage has already occurred.
• Always code the underlying cause of the heart valve replacement if known and relevant to the current encounter.
