Breakdown (mechanical) of biological heart valve graft, init

This code signifies a mechanical failure of a biological (tissue) heart valve graft that has been surgically implanted. This breakdown can manifest as leaflet tearing, calcification, or other structural issues preventing the valve from functioning correctly. It indicates the initial presentation of this specific complication.

Use this code when a patient presents with symptoms or signs directly attributable to a mechanical malfunction of their biological heart valve prosthesis. This applies to the first time this particular complication is documented and treated. It should be used for the initial diagnostic workup and management of the valve's mechanical failure.

• Ensure documentation clearly specifies a biological heart valve and a mechanical breakdown.
• Confirm this is the initial encounter for this specific complication; subsequent encounters would use a different seventh character.
• Always code the underlying heart condition or reason for the original valve replacement as an additional diagnosis, if applicable.
