Structural Bone Block Harvested For Spinal Fusion

Nationwide rates for HCPCS 20938

Covers taking a solid block of the patient's own bone through a separate incision, usually from the hip, and shaping it to sit between the vertebrae as a load-bearing support while the spine fuses. A solid block holds the space open, which loose chips cannot do. It is billed in addition to the spinal operation itself.
