What 22855 covers
This service covers surgical removal of fixation hardware placed along the front of the spine, such as an anterior plate, screws, or related instrumentation. It is typically performed by an orthopedic spine surgeon or neurosurgeon during revision surgery, including cases involving hardware failure, infection, pain, or a change in the treatment plan. The work may occur during a larger spinal operation or as a separate procedure in a facility setting.
Report the code when the operative documentation identifies anterior spinal instrumentation and describes its removal. Distinguish it from removal of posterior hardware based on the approach and location of the construct. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate.

22855 billing questions
How is this distinguished from posterior instrumentation removal?
Use this code for removal of anterior spinal instrumentation. Codes 22850 and 22852 describe removal of posterior instrumentation, with the applicable code depending on the posterior construct.
Can this be reported with new anterior fixation placement?
It may be reported with a new anterior instrumentation code when the surgeon removes the prior construct and places new fixation during the same operation. The record should describe both the removal and the new placement.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this service, and modifier 50 is not appropriate.
What documentation supports reporting this code?
Document the anterior location and type of instrumentation, the removal performed, and the clinical reason for removing it. The operative report should make clear that the work was removal of the spinal construct, not simply exposure or revision of another structure.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Other same-session procedures may also trigger the standard multiple-procedure reduction.
Where these rates come from
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.
