Breakdown (mechanical) of heart valve prosthesis, subs

This code signifies a mechanical failure or malfunction of an artificial heart valve that has been previously implanted. It indicates that the prosthesis itself is experiencing a structural issue, such as a fracture, detachment, or other form of mechanical degradation. This breakdown can compromise the valve's ability to regulate blood flow effectively.

Use this code when a patient presents for follow-up care, evaluation, or treatment related to a previously diagnosed mechanical breakdown of their heart valve prosthesis. This includes admissions for repair, replacement, or management of complications directly stemming from the prosthetic failure. It is appropriate for any encounter after the initial diagnosis and treatment of the breakdown.

• Ensure documentation clearly specifies a mechanical breakdown of the prosthesis, not an infection or other non-mechanical complication.
• Verify that the encounter is for subsequent care related to the breakdown, not the initial diagnosis or the initial insertion of the prosthesis.
• Always code any associated complications or manifestations of the prosthetic breakdown, such as heart failure or embolism, in addition to this code.
