0913T with add-on codes

Date: Mar 11, 2025

Question:

A patient presents to the cath lab for a planned intervention for in-stent restenosis of the RCA. The physician performs lithotripsy followed by brachytherapy and then uses a drug-coated balloon to further dilate the stenosis. How we would code for the brachytherapy and the lithotripsy when using the drug-coated balloon since CPT codes 92972 and 92974 are add-on codes and 0913T is not designated as primary code?
