A nerve graft procedure involves the surgical repair of a damaged nerve in the arm or leg using a single strand of nerve tissue. This technique is employed to facilitate a tension-free repair of the injured nerve, which is crucial for restoring proper nerve function. During the procedure, the surgeon first exposes the injured nerve and assesses the extent of the damage. If necessary, any damaged tissue is carefully removed through a process known as debridement. To evaluate the function of the nerve, additional nerve testing and monitoring may be performed, which are reported separately. The procedure also utilizes microscopic visualization to enhance the precision of the surgery. The healthy segments of the nerve, both proximal and distal to the injury, are meticulously dissected from the surrounding tissue to prepare for the graft. The length of the required nerve graft is then determined, and the graft is harvested from a donor site, which involves exposing the donor nerve and dissecting it free from surrounding tissue. Once the graft is obtained, it is sutured end-to-end to the severed ends of the injured nerve. Finally, the overlying soft tissues and skin are repaired in layers to complete the surgical procedure. It is important to note that this code, CPT® 64893, is specifically used when the length of the nerve graft exceeds 4 cm, while CPT® 64892 is applicable for grafts measuring 4 cm or less.

The nerve graft procedure is indicated for patients who have sustained nerve injuries in the arm or leg that require surgical intervention to restore function. The following conditions may warrant the use of this procedure:
The nerve graft procedure involves several critical steps to ensure successful repair of the damaged nerve. The following outlines the procedural steps:
After the nerve graft procedure, patients can expect a recovery period that may vary depending on the extent of the injury and the surgical intervention. Post-operative care typically includes monitoring for signs of infection, managing pain, and ensuring proper wound healing. Physical therapy may be recommended to aid in the recovery of function and strength in the affected limb. Patients should follow their surgeon's instructions regarding activity restrictions and follow-up appointments to assess the success of the graft and overall recovery.

| 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 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. | 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. | 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. | 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 | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) |
