Question

What is the ICD-10-PCS code for this surgery. Once the central decompression from T12-L1 through L5-S1 was completed, we then used the Midas Rex drill to thin out the lateral recesses in attempt to undermine the joints to gain access to the nerve roots as they are going to the neural foramen. We then used 2 and 3 mm Kerrison rongeurs to remove the significantly hypertrophied ligamentum and allow recesses as well as the osteophytes and stenosis out of the lateral recesses compressing the L2 through S1 nerve roots bilaterally. We identified L2 through S1 nerve roots bilaterally using microdissection technique. I tracked out the neural foramen and used a 2 mm Kerrison rongeur to open up the foramen laterally and to remove soft tissue out, as the nerve roots were going up the foramen to decompress them. A complete foraminotomy was performed L2 through S1 bilaterally. At this point, the thecal sac and nerve roots were well decompressed. A Woodson dissector was used to pass along the nerve roots laterally. We were able to palpate the pedicles. The nerve roots were noted in the neural foramina on either side without any additional compression.
