Case Study: Spinal Surgery-Arthrodesis (December 1999)
December 1999 pages 3-6 Case-by-Case Case Study: Spinal Surgery-Arthrodesis The following operative report describes spinal arthrodesis with the use of instrumentation to treat severe degenerative disc disease with a herniated nucleus pulposus at two vertebral interspaces. The appropriate CPT code choices will be indicated, along with discussion on the selected CPT codes. Please note: As each case is different, the coding information presented in this case study pertains to this case only. Your specific case may vary. Remember to review all available information carefully before choosing the appropriate CPT code(s) for your specific case. Report of Operation Preoperative diagnosis:...

Article Overview
This article reviews a December 1999 CPT case study focused on spinal surgery coding for lumbar arthrodesis. It explains the general coding topics addressed in the operative example, including posterior interbody fusion, spinal instrumentation, and bone graft reporting, along with the CPT guidance discussed for that scenario. The piece is intended for coders, billers, auditors, and other professionals who work with spine surgery documentation and CPT reporting.
Why This Topic Matters
Spine surgery cases often involve multiple related services that must be understood in the context of CPT guidance and the operative record. This article helps readers assess how the premium discussion approaches arthrodesis, instrumentation, and graft-related reporting in a complex lumbar procedure.
Article Sections
-
Case-by-Case
Introduces the operative case and frames the article as a coding review based on one documented spine surgery example. It emphasizes that the discussion is case-specific.
-
Report of Operation
Presents the operative report narrative for the lumbar fusion procedure, including the surgical setting, approach, and major procedural components. The section provides the documentation context used for the coding discussion.
-
Procedure Coding
Walks through the coding analysis tied to the operative report and identifies the main CPT categories addressed in the case. It connects the documentation to the broader spine surgery coding discussion.
-
Discussion-Arthrodesis
Discusses CPT guidance related to lumbar arthrodesis and the classification framework for posterior interbody fusion. The section also addresses how this topic is presented in the CPT 2000 era.
-
Instrumentation
Covers the reporting of spinal instrumentation in the context of the case and summarizes the related CPT discussion. It focuses on how instrumentation is treated alongside arthrodesis in the article.
