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.

The procedure associated with CPT® Code 20937 is indicated for various conditions related to spinal surgery where bone grafting is necessary to promote healing and structural integrity. The following are the explicitly provided indications for this procedure:
The procedure for CPT® Code 20937 involves several critical steps to ensure the successful harvesting and application of the morselized autograft. The following steps outline the process:
After the completion of the procedure associated with CPT® Code 20937, the patient will require careful monitoring and post-operative care. Expected recovery includes managing pain and preventing infection at the incision sites. The patient may be advised to limit physical activity to allow for proper healing of both the graft site and the surgical site on the spine. Follow-up appointments will be necessary to assess the integration of the graft and the overall recovery process. Rehabilitation may be recommended to restore mobility and strength in the affected area.

AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 82 | Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). | GC | This service has been performed in part by a resident under the direction of a teaching physician | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | RT | Right side (used to identify procedures performed on the right side of the body) | LT | Left side (used to identify procedures performed on the left side of the body) | 22 | Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service. | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79.
