Hint: Avoid coding more than once for a vessel's sub-branches Answer 2: You should only use 92980. You won't be reimbursed for any additional codes for the angioplasty of the LAD sub-branches because they are all part of the same major coronary artery. Answer 3: You would report 92980-LD to describe the stenting, single vessel, of the LAD and 92981-RC to describe the stenting, additional vessel, of the RCA. You shouldn't include a separate code for the RCA angioplasty because most payers will consider this part of the stenting procedure the cardiologist eventually performed on that artery. Answer 4: Did you include a code for the atherectomy in the LAD? You shouldn't have. You should only report 92980-LD and 92984-LC. The atherectomy of the LAD is a lesser procedure than the stenting one, so you shouldn't include it on your claim.
Absorb all the intracoronary stent coding advice from "3 Steps to Perfect Intracoronary Stent Placement Coding" on page 81? See how you fared coding these four scenarios.
Answer 1: You'd report 92980-RC (Transcatheter placement of an intracoronary stent[s], percutaneous, with or without other therapeutic intervention, any method; single vessel; right coronary, or RCA) and the "each additional vessel" code, +92981-LD (... each additional vessel [list separately in addition to code for primary procedure]; left anterior descending). This scenario took place in two different vessels--the right coronary and the left descending--so you'd report the two codes. You should not use modifier 51 (Multiple procedures).
