The spine surgeon did a re-exploration of hemilaminectomy at L5-S1 (63042) and a laminectomy at L3-4 and L4-5 (63047, 63048). I code according to RVU's. 63042 has a higher RVU than 63047. However, 63042 is bundled with 63047. Insurance is denying the 63042 as inclusive. From what I have found on internet, it is not appropriate to put 59 modifier on primary procedure. These procedures are done at different levels, and the surgeon should get paid for them. Does anyone have suggestions about this?
