HCPCS 22857

Total disc arthroplasty (artificial disc), anterior approach, including discectomy with end plate preparation (includes osteophytectomy for nerve root or spinal cord decompression and microdissection); single interspace, lumbar

AI EXPLANATION: Lumbar artificial disc replacement surgery is a procedure to replace a worn or damaged spinal disc in the lower back with a specialized prosthetic implant. Approaching the spine through an incision in the lower abdomen, a surgeon removes the damaged disc, relieves pressure on pinched nerves and the spinal cord, and smooths the adjacent bone surfaces. The mobile artificial disc device is then placed between the vertebrae to preserve natural spinal motion and maintain spacing.
