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

This code describes a spinal fusion procedure performed on a lumbar vertebral joint using a custom-designed interbody fusion device. The device is specifically manufactured to fit the patient's unique anatomy, and the procedure is carried out through a percutaneous (minimally invasive) approach. This represents a novel surgical technique or device falling under New Technology Group 7.

This code is appropriate for inpatient encounters where a patient undergoes a lumbar interbody fusion with a patient-specific, anatomically designed implant. It is used when the surgeon explicitly documents the use of such a custom device and a percutaneous approach for the fusion. This typically applies to complex cases where standard off-the-shelf implants may not provide optimal fit or stability.

• Ensure documentation clearly specifies a "custom-made" or "patient-specific" anatomically designed interbody fusion device.
• Verify the approach is documented as "percutaneous" or "minimally invasive" for the lumbar fusion.
• Confirm the procedure falls under New Technology Group 7, as indicated by the final character of the code.
