Fusion 2-4 L Jt w Cust Intbd Fus Dev, Perc, New Tech 7

This code describes a spinal fusion procedure involving two or more lumbar vertebral joints. It specifically utilizes a custom-made, anatomically designed interbody fusion device, meaning the implant is tailored to the patient's specific anatomy and placed between the vertebral bodies. The procedure is performed using a percutaneous approach, indicating a minimally invasive technique.

This code is appropriate for inpatient procedures where a surgeon performs a multi-level lumbar interbody fusion for conditions like severe spinal instability, degenerative disc disease, or spondylolisthesis. The key differentiator is the use of a patient-specific, anatomically designed interbody device inserted through a percutaneous method. It applies when traditional off-the-shelf implants are not used, and a minimally invasive approach is taken.
