X modifiers in the coronary arteries

Date: Feb 25, 2019

Question:

When using multiple PCI codes (92920-92944), is it necessary to add an -X modifier in addition to the vessel modifier (LC, LD, LM, RC, RI)? Procedure performed included angioplasty and stenting of the proximal and distal vein graft to the PDA with two drug-eluting stents as well as angioplasty and stenting of the proximal vein graft to the obtuse marginal artery using one drug-eluting stent. This was done in the setting of an AMI with the PDA being the culprit vessel. Would you code 92941-RC and 92937-LC? Or would you code 92941-RC and 92937-XS-LC? Would -XS ever be appropriate to use when coding the coronary arteries?
