Lumbar Spinal Endoscopy: Mature, Durable, and Established-Not Investigational

Area of Science:

• Minimally Invasive Spine Surgery
• Spinal Endoscopy Techniques
• Lumbar Spine Procedures

Background:

• Lumbar spinal endoscopy has been historically misclassified as investigational by payers.
• This perception contradicts extensive research, clinical trials, and established policy precedents.
• Decades of refinement have advanced the technology and its application.

Purpose of the Study:

• To review the historical development and evidence supporting transforaminal endoscopic lumbar discectomy (TELD).
• To analyze coding, reimbursement, and comparative effectiveness data for TELD.
• To establish TELD as a mature and accessible surgical option.

Main Methods:

• Comprehensive review of historical evolution, prospective trials, and meta-analyses of TELD.
• Emphasis on coding, reimbursement policies, and comparative effectiveness studies.
• Analysis of evidence regarding outcomes, complications, and reoperation rates.

Main Results:

• TELD, with direct visualization, provides durable outcomes comparable or superior to open decompression.
• Meta-analyses confirm TELD's effectiveness is similar to microsurgery.
• Integration with motion-preserving adjuncts enhances durability in complex cases.

Conclusions:

• Transforaminal endoscopy is a safe, durable, and versatile technique for lumbar spine conditions, including central stenosis and spondylolisthesis.
• Evidence supports TELD's efficacy and safety, comparable to traditional open surgery.
• Structured training is essential for reproducibility and broader patient access to TELD.
