Single Level Spinal Fusion Except Cervical without MCC

AI EXPLANATION: L4-L5 spinal fusion is an inpatient surgical procedure that permanently joins the fourth and fifth vertebrae in the lower back. A surgeon uses bone graft material, often accompanied by screws, rods, or cages, to stabilize the joint and promote the growth of solid bone between the two vertebrae. The surgery is typically performed to alleviate chronic pain and instability caused by conditions such as degenerative disc disease, spondylolisthesis, or spinal stenosis.
