Thrombosis due to cardiac prosth dev/grft, initial encounter

This diagnosis code indicates the formation of a blood clot within or around an implanted cardiac device, such as a pacemaker lead, artificial heart valve, or coronary stent. This thrombosis is a direct complication of the prosthetic device itself, impeding blood flow and potentially leading to serious cardiovascular events.

Use this code when documenting a patient presenting with symptoms or signs of a new or acute blood clot directly attributable to a previously implanted cardiac prosthetic device. This applies to the initial evaluation and treatment of the thrombotic event.

• Ensure documentation clearly links the thrombosis to the specific cardiac prosthetic device.
• Confirm this is the patient's first encounter for this particular thrombotic complication.
• Specify the type of cardiac prosthetic device if known and documented.
