One of our surgeons was going to remove a clavicular mass that is in the deep tissue/muscle of a pt but when he got in there, he was unable to remove the entire mass as it was attached to the subclavian vein. He then decided to just take a biopsy of the mass and call it good. It came back as a malignant melanoma. I cannot find a CPT code for the biopsy. If anyone has any ideas, please let me know! Thanks!
