CPT® Code 20937

Add-On Code

Autograft for spine surgery only (includes harvesting the graft); morselized (through separate skin or fascial incision) (List separately in addition to code for primary procedure)

The CPT® Code 20937 refers to the procedure of harvesting and utilizing an autograft specifically for spine surgery. An autograft is a type of graft that is derived from the patient's own body, ensuring compatibility and reducing the risk of rejection. In this case, the graft is morselized, meaning it is broken down into smaller pieces to facilitate its integration into the surgical site. The harvesting of the graft occurs through a separate incision, which is distinct from the primary surgical site on the spine. This procedure is essential for promoting bone healing and regeneration in spinal surgeries, as the autologous bone contains vital components such as osteoblasts, which are responsible for bone formation, and bone morphogenic proteins that aid in the growth of new bone tissue. The graft can be harvested from various locations, including the iliac crest, ribs, or other areas, depending on the specific needs of the surgical procedure. The use of a morselized graft allows for better packing into the bone defect, enhancing the chances of successful healing and recovery following spinal surgery.
