CPT 64783: Additional Peripheral Nerve Neuroma Excision of Hand or Foot

CPT code 64783 covers the surgical removal of an additional tumor or neuroma on a peripheral nerve of the hand or foot performed during the same operative session as an initial neuroma excision. The procedure addresses pain relief and restoration of nerve function resulting from neuromas caused by injury or trauma, and explicitly excludes digital neuromas of the fingers and toes. Nationally, this code is relevant for hand and foot surgeons, surgical practices, and payers managing post-traumatic peripheral nerve care.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The summary discusses coverage patterns, claims handling considerations, and clinical context that affect coding and reimbursement for peripheral nerve tumor excision in ambulatory surgical centers and hospital operating rooms.

Readers will learn the clinical intent and appropriate use of the code, typical sites of service, common billing considerations, and where to look for policy updates or payer guidance. Data not available in the input is noted where applicable; the narrative focuses on code definition, clinical scope, and payer coverage landscape rather than specific state policies or proprietary benchmark values.

Billing Code Overview

CPT code 64783 describes surgical excision of an additional neuroma or mass arising from a peripheral nerve of the hand or foot performed during the same operative session as removal of an initial neuroma. The procedure is intended to relieve pain and restore nerve function lost because of neuroma formation after injury or trauma. This code specifically excludes neuromas located in the fingers or toes (digital neuromas).

Service type: Surgical excision of peripheral nerve tumor or mass (additional neuroma) during the same session as primary neuroma removal
Typical site of service: Ambulatory surgical center or hospital operating room for procedures on the hand or foot

Clinical & Coding Specifications

Clinical Context

A 48-year-old construction worker presents to a hand surgeon with persistent, neuropathic pain and numbness along the distribution of a peripheral digital branch in the dorsum of the foot following a crush injury two years prior. Examination identifies a tender, palpable mass along a peripheral nerve in the foot consistent with a neuroma. The surgeon elects to remove an initial symptomatic neuroma under regional or general anesthesia. During the same operative session, the surgeon identifies a second, distinct neuroma on a different peripheral nerve of the foot and elects to excise it as well. The procedure aims to relieve pain and restore function by resecting both neuromas and performing appropriate nerve repair or burying techniques.

Workflow steps:

Preoperative evaluation and consent in clinic, documentation of history of prior injury, focal exam, and imaging or nerve conduction studies as indicated.
Day-of-service verification, anesthesia evaluation (regional block or general), and marking of surgical site.
Operative procedure: identification and excision of initial neuroma, then excision of additional neuroma on a different peripheral nerve in the same hand or foot during the same session. Intraoperative documentation notes nerve levels, technique used (resection, traction neurectomy, nerve repair/relocation), and estimated blood loss.
Immediate postoperative monitoring, pain control, and discharge with wound care and activity restrictions.
Follow-up visits to assess pain relief, wound healing, and sensory or motor recovery; therapy or orthotic referral as indicated.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier required (placeholder)	Not typically appended; used per payer if required for unmodified claims.

| 11 | Professional component | Use when reporting only the professional component if payer requires separate facility reporting (rare for surgery).

| 22 | Increased procedural services | Use when work required is substantially greater than typical (document justification).

| 23 | Unusual anesthesia | Use when procedure performed under general anesthesia because of patient condition contraindicating local/regional anesthesia.

| 26 | Professional component | Applicable if technical component billed separately by facility; surgeons typically use 26 when payer requires separation.

| 50 | Bilateral procedure | Use when the same procedure is performed on both right and left extremities in the same session.

| 52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned.

| 53 | Discontinued procedure | Use when procedure is started but discontinued for patient safety reasons.

| 62 | Two surgeons | Use when two surgeons of different specialties perform distinct, documented portions of the procedure.

| 76 | Repeat procedure by same physician (not in provided list) | Data not available in the input.

Taxonomy Code	Specialty	Notes
207P00000X	Orthopedic Surgery	Orthopedic hand/foot surgeons frequently perform peripheral nerve tumor resections.

| 207X00000X | Plastic Surgery | Plastic surgeons with hand specialty perform neuroma excisions and nerve reconstruction.

| 2080P0004X | Surgery of the Hand | Hand surgery specialists (orthopedic or plastic) commonly perform this code.

| 2082P0800X | Podiatric Surgery | Podiatrists with surgical specialty perform neuroma excisions in the foot.

| 2086S0124X | General Surgery | General surgeons less commonly perform peripheral nerve excisions of the extremities.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`G56.40`	Lesion of unspecified radial nerve	Peripheral nerve lesions producing pain and dysfunction that may present as neuroma requiring excision.

| G57.91 | Lesion of unspecified peroneal nerve | Peroneal nerve injuries can lead to symptomatic neuromas in the foot that may be treated with excision.

| G56.01 | Carpal tunnel syndrome, right upper limb | Nerve entrapment conditions may coexist; while distinct, documentation must support procedures performed.

| M79.2 | Neuralgia and neuritis, unspecified | Symptom code often used to capture neuropathic pain associated with neuroma.

| S64.511A | Injury of digital nerve of right index finger, initial encounter | Digital nerve injuries are clinically related but digital neuromas are excluded from 64783 and require different coding.

| S84.011A | Injury of superficial peroneal nerve, initial encounter | Acute nerve injury codes may underlie development of neuroma treated by excision.

CPT Code	Description	Relationship to This Procedure
`64782`	Neuroplasty and/or transposition; of peripheral nerve of hand or foot (separate procedure)	May be performed when adhesions or nerve entrapment coexist and require neuroplasty in the same operative session.

| 64784 | Excision of neuroma; of major peripheral nerve of the arm or leg (not digital) | Alternative code when excising a neuroma of a major named peripheral nerve; selection depends on nerve involved and code definitions.

| 20680 | Removal of implant; deep (e.g., buried hardware) when indicated | May be performed if prior hardware contributes to nerve irritation and requires removal during the same operative encounter.

| 64721 | Neuroplasty and/or transposition; peripheral nerve, arm or leg (not digital) | Performed when nerve decompression or transposition is indicated in addition to neuroma excision.

| 28122 | Excision of plantar neuroma; intermetatarsal (Morton neuroma) | Performed for neuromas in the forefoot; distinct from peripheral nerve neuromas of the foot covered by 64783.
