Summary & Overview
CPT 64630: Neurolysis for Pain Management
CPT code 64630 denotes neurolysis, the destruction of nerves that carry pain information using chemical, heat, or radiofrequency methods. This interventional pain-management procedure is used for patients with focal, refractory pain where targeted nerve interruption may provide diagnostic or therapeutic benefit. Nationally, neurolytic techniques are significant because they can reduce opioid reliance, change care trajectories for chronic pain, and affect facility and professional billing patterns given variable payer coverage and utilization.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for neurolysis, typical sites of service (hospital outpatient departments, ambulatory surgery centers, and specialized pain clinics), and the operational relevance of CPT code 64630 for coding and billing workflows. The publication outlines benchmarks and policy-relevant considerations such as coverage variability, documentation expectations, and alignment with pain-management best practices. Where input data is absent, the text notes that information was not provided. The goal is to give billing, coding, and policy stakeholders a clear national-level summary of what CPT code 64630 represents and why it matters for payer coverage and clinical coding processes.
Billing Code Overview
CPT code 64630 describes neurolysis, the intentional destruction of nerves responsible for transmitting pain signals. The procedure can be performed using chemical, thermal (heat), or radiofrequency techniques to disrupt nociceptive pathways and provide pain relief.
Service type: Interventional pain management procedure (neurolytic nerve destruction)
Typical site of service: Hospital outpatient department, ambulatory surgery center, or specialized pain clinic

Clinical & Coding Specifications
Clinical Context
A 58-year-old male with a multi-year history of refractory lumbar radicular pain from post-lumbar discectomy scarring presents to an interventional pain clinic after failing conservative care including oral analgesics, physical therapy, and epidural steroid injections. Imaging demonstrates focal scar encasing the S1 nerve root concordant with dermatomal pain and neurologic exam correlates. The interventional pain specialist discusses a percutaneous image-guided radiofrequency neurolysis targeting the affected dorsal root ganglion to interrupt nociceptive signals.
The clinical workflow includes pre-procedure evaluation and informed consent, review of risks/benefits and anticoagulation status, procedural time-out, sterile preparation in an ambulatory surgery center or hospital outpatient setting, fluoroscopic or CT-guided needle placement, sensory/motor stimulation testing as indicated, delivery of thermal radiofrequency lesioning (or chemical/neurolytic agent if selected), post-procedure monitoring for anesthesia recovery and neurologic assessment, discharge with post-procedure instructions, and scheduled follow-up to assess pain relief and possible repeat neurolysis if indicated. Typical site of service is an ambulatory surgery center or hospital outpatient department using fluoroscopy or CT guidance.
