Medical Necessity for Spinal Cord Stimulator Trial in Postlaminectomy Syndrome
Indication and Evidence Base
- The American Society of Anesthesiologists guidelines recommend spinal cord stimulation for patients with persistent radicular pain who have not responded to other therapies 1
- Postlaminectomy syndrome (failed back surgery syndrome) with low back pain and significant radicular pain is an established indication for spinal cord stimulation when conservative treatments have failed 1
Patient Selection Criteria
- The patient is at least 6 months post-operative from his lumbar fusion surgery 1
Trial Procedure Rationale
- The requested procedures (63650 x2 for percutaneous electrode placement, L8680 x16 for the electrodes, and 95972 for electronic analysis) are appropriate for a comprehensive SCS trial 1
Expected Benefits
- For patients with postlaminectomy syndrome, SCS may provide better pain control than reoperation 2, 3
- Significant pain reduction during the trial period would be a strong indicator of long-term success with permanent implantation 1
Limitations and Considerations
- Some patients may experience diminishing effectiveness over time, potentially requiring system revision 4
