thrombectomy, open vs percutaneous
I am looking for clarification of how to code a thrombectomy from an AV graft. The surgeon dissected down to the graft and the graft was dissected out proximally and distally. The graft was opened transversely with a blade. Then a Fogarty catheter was used to retrieve the thrombus from the arterial side of the graft. In discussion with coders, they feel this is a percutaneous procedure since the clot was retrieved with a catheter. is this an open or percutaneous thrombectomy?
