The fourth character identifies Lower Artery. The fifth distinguishes an open incision, a puncture or small incision with or without a scope, and work done externally. The sixth distinguishes drainage, monitoring, infusion and other devices; devices inside or outside the artery’s channel; and tissue or synthetic substitutes. The seventh is always No Qualifier.
