Breakdown (mechanical) of heart valve prosthesis, sequela

This code signifies a mechanical failure or malfunction of an implanted artificial heart valve, occurring as a late effect or complication. This breakdown can involve structural integrity issues, such as leaflet tears, strut fractures, or detachment, leading to impaired valve function.

Use this code when documenting a patient presenting with symptoms or findings directly attributable to a previously implanted heart valve prosthesis that has mechanically failed. This applies to situations where the initial complication has resolved, but the patient is now experiencing the long-term consequences of that breakdown.

• Requires a seventh character "S" for sequela, indicating a complication or condition that arises as a direct result of an earlier injury or disease.
• Do not use for acute or initial mechanical complications; those would typically use the "A" or "D" seventh characters.
• Always code the specific type of heart valve prosthesis (e.g., aortic, mitral) if known and documented, using a more specific code from the T82.0 series if available.
