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

What 22846 covers

This code represents an anteriorly placed fixation construct spanning four to seven vertebral segments. A spine surgeon may use a plate-and-screw construct to stabilize the spine during an anterior fusion, such as multilevel cervical fusion, or another qualifying spinal operation. The construct’s approach and span distinguish this service from posterior fixation and from a device placed within an interspace.

Select the code by counting the vertebral segments instrumented, not the number of screws or the number of disc spaces treated. The operative report should identify the anterior approach and the segments spanned by the fixation construct. This is an add-on code: report it only with a qualifying primary procedure, not by itself. CMS payment is tied to the primary procedure’s global period.

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.
