Problem:
A patient with severe spinal stenosis was positioned lying face down. The physician made a midline incision overlying the affected vertebrae bilaterally at L4-L5 and unilaterally on the left side at L5-S1. Fascia is incised. Paravertebral muscles are retracted. The physician removed the spinous processes with rongeurs. The physician removed the lamina out to the articular facets using a burr. Half of the lamina was removed. A Penfield elevator peeled the ligamentum flavum away from the dura. Nerve root canals were freed by additional resection of the facet, and compression was relieved by removal of any bony or tissue overgrowth around the foramen. Removal of the lamina, facets, and bony tissue or overgrowths was performed bilaterally. The rongeur, retractor, and microscope are removed. A free-fat graft was placed over the nerve root(s) for protection. The spared ligamentum flavum was placed over the free-fat graft. Paravertebral muscles were repositioned, and the deeper tissues and skin were closed with layered sutures. What CPT codes and modifiers (if any) are appropriate? Need Assignment Help?
