Breakdown (mechanical) of biological heart valve graft, subs

This code signifies a mechanical failure or malfunction of a biological heart valve graft that has been previously implanted. This breakdown can manifest as structural deterioration, leaflet tearing, or other issues compromising the valve's function. It indicates that the patient is receiving care for complications arising from the graft's mechanical failure, not the initial implantation.

Use this code for follow-up encounters where a patient is being treated for a confirmed mechanical breakdown of their biological heart valve graft. This includes office visits, hospital admissions, or outpatient procedures addressing the failed valve. It is appropriate when the patient is beyond the initial healing phase of the original valve replacement.

• Ensure documentation clearly specifies a biological heart valve graft and a mechanical breakdown.
• Verify the encounter is for subsequent care, not the initial treatment of the complication.
• Always code with an additional code to specify the type of heart valve disorder, if known.
