Breakdown of biological heart valve graft, sequela

This code signifies a long-term complication arising from the mechanical failure of a biological heart valve graft. It indicates that the previously implanted tissue valve has experienced a structural issue, such as tearing, calcification, or leaflet dysfunction, that is causing current clinical symptoms or requiring intervention.

Use this code for patients presenting with symptoms or findings (e.g., echocardiographic evidence) of a mechanical problem with their biological heart valve graft that occurred in the past and is now being addressed. This applies to situations where the initial breakdown event has already happened, and the patient is experiencing its lasting effects.

• This code is for the sequela (long-term effect) of the breakdown, not the acute event itself.
• Always code the specific type of mechanical breakdown if known (e.g., T82.211S for leakage, T82.221S for breakdown).
• Consider additional codes for any associated conditions or symptoms (e.g., heart failure, endocarditis) that result from the valve graft breakdown.
