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

What 22633 covers

This code represents fusion at one lumbar interspace using both an interbody approach from the back and posterolateral fusion. The surgeon prepares the disc space and places material intended to promote fusion between the vertebrae, while also fusing the posterior-lateral elements. It is generally performed by a spine surgeon in a hospital or other operative facility for conditions such as degenerative disease or instability requiring fusion.

Report it only when both fusion techniques are performed at the same lumbar interspace; a single technique calls for a different code. The operative report should identify the treated level and document the interbody and posterolateral work. For another interspace treated with both techniques, 22634 is the add-on code. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and others at 50%. Assistant-at-surgery payment and co-surgeons are permitted; team surgery is not. Modifier 50 is inappropriate for this code.
