Surgery: Musculoskeletal System (November 2007)
November 2007 page 8a Coding Communication: Surgery: Musculoskeletal System Question: 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)? Answer: Anterior instrumentation codes 22845 - 22847 may be reported separately with modifier 59, Distinct procedural service...

Article Overview
This CPT Assistant article clarifies a musculoskeletal surgery coding issue involving anterior spinal instrumentation across separate cervical levels. It is relevant for coders, billers, and compliance staff who work with spine surgery documentation and need to understand how the article discusses code selection, separate constructs, and modifier use in a cervical instrumentation scenario. The piece focuses on a specific coding communication and explains the general reporting approach described in the question-and-answer format.
Why This Topic Matters
Spine instrumentation cases can involve multiple fused and non-fused segments, making accurate CPT reporting important for compliant claim submission and consistent interpretation of documentation. This article provides guidance on a nuanced scenario that can affect how separate constructs are captured in the musculoskeletal surgery section of CPT.
