Our neurosurgeon has a coding question regarding placement of an anterior buttress plate/screws placement when it is attached to a PEEK device. He said the vendor rep told him to bill 22845 (anterior plate) and 22851 (PEEK) even though the screws are only placed on one vertebral body. Is this correct?
You are wise to check out this advice. The anterior instrumentation code, 22845, is reported when the plate is a separate device not attached to the PEEK device and can provide independent stabilization on its own. Many of these devices do not meet this criteria so only 22851 is appropriate to code.
