What is the appropriate code to report if anterior instrumentation is inserted at vertebral segments C3-4 and additional instrumentation is inserted at C6-7, but vertebral segments C4-5 and C5-6 are not fused? Are the anterior instrumentation codes assigned strictly by the TOTAL number of spinal segments with instrumentation applied (ie, 22846 ) or is the appropriate code chosen based on the vertebral segments involved in each separate construct (ie, 22845 , 22845 59)? ...

Article Overview
This article explains a coding question involving anterior spinal instrumentation performed at different vertebral levels and whether reporting is based on the overall count of instrumented segments or on separate constructs. It is relevant to coders and billing staff working with spine surgery documentation and CPT reporting conventions, especially where modifier 59 may be involved in distinguishing distinct procedural services.
Why This Topic Matters
Spine instrumentation cases can involve more than one construct, and correct reporting affects claim accuracy and compliance. The article helps readers understand the general coding issue and where modifier usage may come into play.
