Leakage of biological heart valve graft, initial encounter

This code signifies a malfunction in a biological heart valve replacement where there is an escape of blood through or around the valve. This leakage indicates the valve is not closing properly, leading to regurgitation or insufficiency. It represents the initial presentation or active treatment phase of this complication.

Use this code when a patient presents with symptoms or diagnostic findings (e.g., echocardiogram) confirming leakage of a previously implanted biological heart valve. This applies to the first time the patient is being treated for this specific complication. It would be appropriate for initial hospital admissions or outpatient visits addressing the acute issue.

• Ensure documentation clearly specifies a "biological" heart valve, not a mechanical one.
• Confirm this is the "initial encounter" for the leakage; subsequent encounters for the same issue will use different seventh characters.
• Code any associated symptoms or underlying causes of the leakage in addition to this code.
