Thrombosis due to vascular prosth dev/grft, subs

This code signifies the formation of a blood clot within or around an implanted vascular device, such as a stent, graft, or artificial valve, that is still present in the patient. This thrombosis is a complication directly attributable to the presence of the prosthetic material.

Apply this code when a patient presents for follow-up care, treatment, or management of a previously diagnosed thrombosis that developed due to a vascular implant. This includes situations where the patient is receiving ongoing anticoagulation therapy or undergoing further diagnostic workup for the existing clot.

• Ensure documentation clearly links the thrombosis to the specific vascular prosthetic device.
• Confirm the encounter is for subsequent care of the thrombosis, not the initial diagnosis.
• Do not use for thrombosis unrelated to the prosthetic device or for complications of the device other than thrombosis.
