Thrombosis due to cardiac prosth dev/grft, subs

This code signifies a blood clot forming within or around an artificial heart device, implant, or graft, such as a prosthetic valve, pacemaker lead, or coronary stent. This thrombosis is a complication directly related to the presence of the cardiac prosthetic material.

Use this code when a patient presents for follow-up care, monitoring, or treatment of a previously diagnosed thrombosis that developed due to a cardiac prosthetic device. This applies to situations where the initial treatment for the thrombosis has already been provided, and the patient is now in a subsequent phase of care.

• Ensure documentation clearly links the thrombosis to the specific cardiac prosthetic device.
• Verify that the encounter is indeed "subsequent" and not the initial diagnosis or treatment of the thrombosis.
• Code any associated symptoms or complications of the thrombosis separately, if applicable.
