My provider was on call at a facility and looks like he saw a pt for initial consultation. The next day he assisted in surgery for this pt. Aetna denied the 99254 as global and the 49204 reason denial is N674-Not covered unless a pre-requisite procedure/service has been provided and also B15-This service/procedure requires that a qualifying service/procedure be received and covered. The qualifying other service/procedure has not been received/adjudicated. Looked in cpt book but doesn’t state anything should be done additional for this surgery. I am thinking its the pts policy and coverage but rep told me just to send medical records. Any idea what this pre requiste procedure/service could be?
