One of our surgeons performed angiograms and subclavian sheath removal of a Cordis sheath for a patient who had the sheath placed in the artery during a craniotomy. Our physician was not the one who placed the catheter in the first place, but is doing the angiograms and removal of it after the craniotomy. Is there anything I can bill for the sheath removal or am I only able to bill for the angiograms? Thanks.
