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

What 22224 covers

A spine surgeon uses an anterior approach to remove disc and adjacent bone at one lumbar vertebral segment, creating mobility for correction of a fixed spinal deformity or alignment problem. This work may be part of a larger reconstruction that includes lumbar fusion. The code includes the discectomy integral to the osteotomy at that segment; it is not simply a code for routine disc removal or an interbody fusion.

Report one unit for the treated lumbar segment and document the operative level, anterior approach, bone and disc work, and its role in the correction. When osteotomy is performed at another segment, 22226 is the add-on code for each additional segment. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
