Fusion Lumsac Jt w Cust Intbd Fus Dev, Perc Endo, New Tech 7

This code describes a spinal fusion procedure specifically at the lumbosacral joint (L5-S1) utilizing a custom-made, anatomically designed interbody fusion device. The procedure is performed percutaneously using an endoscopic approach, representing a minimally invasive technique. This particular device and approach fall under New Technology Group 7 within ICD-10-PCS.

This code is appropriate for inpatient encounters where a patient undergoes a minimally invasive L5-S1 interbody fusion due to conditions like degenerative disc disease, spondylolisthesis, or spinal instability. The key is the use of a custom-made, anatomically designed interbody device and the percutaneous endoscopic approach.

• Verify documentation explicitly states "custom-made" and "anatomically designed" for the interbody device.
• Confirm the approach is "percutaneous endoscopic" and the joint fused is specifically the lumbosacral joint (L5-S1).
• Ensure the operative report confirms the use of a New Technology Group 7 device.
