Clinical Context
A 45-year-old right-handed construction worker presents with persistent, severe pain and numbness in the index and middle fingers of the right hand after a crush injury six months prior. Examination demonstrates point tenderness and a palpable, tender nodular mass along the digital nerve of the index finger consistent with a symptomatic neuroma, and a smaller, painful neuroma in the middle finger identified on exam and confirmed with ultrasound. Nonoperative measures (analgesics, splinting, and a steroid injection) have failed to relieve symptoms. The surgeon schedules operative neuroma excision under regional block with monitored anesthesia care.
During a single operative session the provider performs primary excision of the symptomatic neuroma in the index finger and, recognizing a second distinct neuroma in the adjacent middle finger, performs excision of that additional neuroma at the same session. The procedure aims to remove scarred nerve tissue, perform neuroma resection with nerve stump management (burying the nerve end or reconstruction as indicated), and restore function while alleviating neuropathic pain. Typical perioperative workflow includes preoperative consent, regional anesthesia (digital block or brachial plexus block), sterile preparation of the digits, excision of neuromas, hemostasis, soft tissue closure, dressing and postoperative instructions, and follow-up for wound check and hand therapy as needed.
Typical site of service: outpatient ambulatory surgery center or hospital outpatient department. Service type: peripheral nerve surgery (digital neuroma excision). Typical patient: adults with post-traumatic or postsurgical neuroma of a digital peripheral nerve causing pain, paresthesia, or functional impairment.

RT | Right side | When the procedure is performed on the right digit |
59 | Distinct procedural service (Note: not in raw list) | Data not available in the input. |
76 | Repeat procedure by same physician (Note: not in raw list) | Data not available in the input. |
22 | Increased procedural services | When work is substantially greater than typical for 64778 due to complexity or extensive dissection |
52 | Reduced services | When the procedure is partially reduced or not completed as originally planned |
53 | Discontinued procedure | When the procedure is terminated before completion for patient safety reasons |
62 | Two surgeons | When two surgeons work together as primary surgeons for a complex reconstruction involving the nerve |
63 | Procedure performed on infants less than 4 kg (Note: limited applicability) | Use when patient meets criteria for neonatal modifier and anatomy warrants coding adjustments |
76 | Repeat procedure by same physician (from provided list 76 not present) | Data not available in the input. |
78 | Unplanned return to the operating room for a related procedure during the postoperative period | When the patient returns to the OR for a complication of the original neuroma excision |
79 | Unrelated procedure or service during the postoperative period (Note: not in raw list) | Data not available in the input. |
LT | Left side (duplicate entry prevented) | Use as above |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
64778 | Excision of tumor, etc., of peripheral nerve, finger or toe; each additional tumor removed at same session (separate procedure) | This is the specific additional-tumor code used when a second distinct digital neuroma is excised during the same operative session after the primary neuroma removal |
64772 | Excision of tumorous or nontumorous lesion of peripheral nerve; single lesion, peripheral nerve | Often used for the primary excision of the initial neuroma when only one lesion is removed during the session |
64763 | Neuroplasty and/or transposition; median nerve at carpal tunnel (likely unrelated) | May be reported if concurrent proximal nerve decompression (e.g., carpal tunnel release) is performed in the same operative setting and is unrelated to the digital neuroma excision |
64831 | Repair of single peripheral nerve, hand or foot, without free nerve graft; 1st digital nerve | Reported when nerve repair is performed as part of neuroma management rather than simple excision and stump management |
69990 | Microsurgical techniques, requiring use of an operating microscope (list separately in addition to code for primary procedure) | Reported in addition when significant microscopic dissection or nerve repair necessitates operative microscope use |
If other related codes are required for global reporting of anesthesia, facility, or monitoring services, those are reported separately per payer rules.
