Official Description

Implantation of nerve end into bone or muscle (List separately in addition to neuroma excision)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 64787 refers to the procedure of implanting a nerve end into either bone or muscle, which is performed as a separate procedure following the excision of a neuroma. A neuroma is a benign growth that occurs when nerve tissue is damaged, often leading to pain and discomfort. The implantation of the nerve end serves a dual purpose: it inhibits the formation of scar tissue, which can complicate recovery and lead to further nerve damage, and it protects the nerve end from recurrent trauma, a significant factor in the development of new neuromas. This procedure is critical in ensuring that the nerve has a better chance of healing and functioning properly after the excision. The process involves careful dissection of the nerve to free it from surrounding tissues, allowing for its relocation into nearby muscle or bone, thereby facilitating a more favorable healing environment for the nerve. This procedure is distinct and must be reported separately from the neuroma excision, highlighting its importance in the overall management of nerve injuries and conditions related to neuromas.

1. Indications

The procedure described by CPT® Code 64787 is indicated for patients who have undergone excision of a neuroma. The following conditions may warrant this procedure:

  • Neuroma Excision Patients with a diagnosed neuroma that has been surgically excised may require nerve end implantation to prevent complications associated with scar tissue formation and recurrent trauma.
  • Chronic Pain Individuals experiencing chronic pain due to nerve damage or irritation may benefit from this procedure to enhance nerve healing and function.
  • Nerve Injury Patients with nerve injuries that have led to the formation of a neuroma may need this intervention to facilitate proper nerve regeneration and reduce the risk of further neuroma development.

2. Procedure

The procedure for CPT® Code 64787 involves several critical steps to ensure the successful implantation of the nerve end into bone or muscle:

  • Step 1: Neuroma Excision The procedure begins with the excision of the neuroma, which is a separate reportable procedure. This step is essential to remove the abnormal nerve growth that may be causing pain or discomfort.
  • Step 2: Nerve Dissection Following the excision, the nerve is carefully dissected proximally. This dissection is performed to free enough nerve tissue from the surrounding structures, allowing for the relocation of the nerve end into the nearby muscle or bone.
  • Step 3: Implantation in Muscle If the decision is made to implant the nerve end into muscle tissue, a small incision is made in alignment with the muscle fibers. The nerve end is then implanted into the muscle and secured in place using sutures to ensure stability and promote healing.
  • Step 4: Implantation in Bone If the nerve end is to be implanted in bone, the overlying soft tissue is dissected to expose the bone. The periosteum, which is the outer layer of the bone, is incised to facilitate access. A small drill is then utilized to create a hole through the compact bone and into the medullary canal, where the nerve end is inserted through the drill hole, ensuring it is properly positioned within the medullary canal.

3. Post-Procedure

After the implantation procedure, patients may require specific post-operative care to ensure optimal recovery. This may include monitoring for signs of infection at the surgical site, managing pain with appropriate medications, and following up with physical therapy to promote healing and restore function. Patients should be advised on activity restrictions to prevent undue stress on the implanted nerve end, and regular follow-up appointments may be necessary to assess the healing process and the effectiveness of the nerve implantation.

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.
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.
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. (for repeat procedures on the same day, see modifier 76.)
