Answer: Code 69990 (use of operating microscope [list separately in addition to code for primary procedure]) applies to complex spinal surgeries. Medicare will not reimburse for 69990, but private payers should. While you may get some initial denials, many coders report having success with appeals. To bolster your documentation with these claims, include a copy of the coding information from the North American Spine Societys Common Coding Scenarios for Spine Procedures & Injection Techniques.
