Ask Dr. Z

Please clarify intervention on the acute marginal branch. Is the acute marginal considered a branch of the right coronary? Should we report codes 92928-RC and 92929-RC for the following intervention? "We successfully advanced a 2.5 x 22 mm Resolute drug-eluting stent over the ATW Marker wire and positioned it across the mid RCA stenosis where it was deployed using up to 16 ATM. We then advanced a 2.25 x 12 mm Resolute drug-eluting stent across the proximal acute marginal branch stenosis where it was deployed using up to 15 ATM. The stent balloon was pulled back slightly and used to post-dilate the area of overlap between the deployed stents."
