I need some advice about using an add-on code for lumbar discectomies. Dr. performed laminectomy at L1-2 and then made a new incision and performed laminectomy at L4-5? Should I just use the add-on code of 63047 and 63048 or should I use 63047, 63048, 63048-59, 63048-59 to indicate that Dr. surgeon performed L1, L2, L4, L5 laminectomies? He did indeed peforme 4 laminectomies to decompress the spinal cord. Notice the space between those levels (L2-3). Thank you, Jill CPC
