Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 22533 covers

This code describes fusion of a lumbar vertebral segment through a lateral extracavitary exposure. The surgeon reaches the spine through a lateral, posterior-side corridor and may remove a limited amount of disc tissue to prepare the space for fusion. That preparation is part of the service; the code is not for a discectomy performed to decompress neural structures. Spine surgeons typically perform the operation in a hospital operating room for a lumbar segment requiring stabilization and fusion.

Report 22533 for the lumbar level and use 22534 for each additional vertebral segment when applicable. The operative report should identify the lumbar level, approach, fusion work, and any additional segments. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment and co-surgeons are permitted; team surgery is not. Modifier 50 is inappropriate for this code.
