The new CPT update also includes some codes for arthrodesis by lateral extracavitary technique: 22532, (... including minimal diskectomy to prepare interspace; thoracic) 22533 (... lumbar) and +22534 (... thoracic or lumbar, each additional vertebral segment). This will help surgeons distinguish extracavitary technique from other techniques, such as anterolateral (22548-22556) or posterior (22590-22614).
CPT also adds three codes to describe vertebral corpectomy by lateral extracavitary approach: 63101 (... with decompression of spinal cord and/or nerve root[s]; thoracic, single segment), 63102 (... lumbar, single segment) and +63103 (... thoracic or lumbar, each additional segment).
