Provider performed laser atherectomy of the subclavian artery. CPT code 35475, which would describe this procedure, has been deleted. The claim has been denied and we’re trying to appeal with a comparable code for the procedure. Can you please assist with identifying a comparable code?

CPT Category III code 0237T describes atherectomy in the brachiocephalic vessels, which would include the subclavian artery. Be sure the device you are using is FDA approved for the vessel treated. The catheter placement and angioplasty (if done) are additionally reported with atherectomy code 0237T.
