Summary & Overview
HCPCS C7551: Excision of Major Peripheral Nerve Neuroma with Implantation
HCPCS Level II code C7551 covers the surgical excision of a major peripheral nerve neuroma (excluding sciatic) with implantation of the nerve end into bone or muscle. The code identifies a targeted surgical technique used to manage symptomatic neuromas that cause chronic neuropathic pain and functional impairment. Nationally, accurate use of this code supports clinical documentation, appropriate payment for complex peripheral nerve procedures, and consistent tracking of neuroma-focused surgical interventions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, common billing modifiers, and what to expect in terms of typical sites of service. The publication summarizes benchmark considerations and coding guidance relevant to surgical specialties that perform peripheral nerve reconstructions.
This summary provides clinicians, coding professionals, and revenue cycle staff with concise context: the clinical indication and procedure type, settings where the service is commonly delivered, and the principal payers whose policies are commonly referenced in national analyses. Data not available in the input is noted where applicable in detailed sections.
Billing Code Overview
HCPCS Level II code C7551 represents excision of a major peripheral nerve neuroma, except sciatic, with implantation of the nerve end into bone or muscle. This procedure involves surgical removal of a symptomatic neuroma from a major peripheral nerve (excluding sciatic nerves) and implantation of the proximal nerve stump into adjacent bone or muscle to reduce recurrent neuroma pain and improve functional outcomes.
Service type: surgical, peripheral nerve surgery
Typical site of service: operating room or ambulatory surgical center, with postoperative care delivered in inpatient or outpatient surgical recovery settings depending on clinical complexity.
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents with persistent, localized neuropathic pain and a palpable tender mass along a peripheral nerve in the forearm following prior trauma and attempted nerve repair. Conservative care including medications, nerve blocks, and physical therapy provided incomplete relief. Imaging and ultrasound localize a symptomatic neuroma of a major peripheral nerve (not the sciatic nerve). The surgical team — typically a hand or peripheral nerve surgeon in an ambulatory surgery center or hospital outpatient department — schedules excision of the neuroma with implantation of the proximal nerve end into adjacent muscle or drilled cortical bone to reduce recurrent neuroma formation and pain. The clinical workflow includes preoperative evaluation and informed consent, perioperative regional or general anesthesia, surgical excision of the neuroma, implantation of the nerve end into muscle or bone, intraoperative documentation of nerve level and laterality, postoperative monitoring in PACU, and discharge with wound care and follow-up for pain management and rehabilitative therapy. Typical site of service: hospital outpatient surgery or ambulatory surgery center. Service type: major peripheral nerve surgery with implantation of nerve end into bone or muscle.
