CPT® Code 64640 is used to report the destruction of a peripheral nerve or nerve branch using a neurolytic agent. The procedure is designed to interrupt nerve signaling and may be performed to manage chronic or otherwise difficult-to-treat pain affecting a specific peripheral nerve.
Neurolytic procedures may use agents such as chemical neurolytic substances to produce targeted nerve destruction. The appropriate nerve or nerve branch and clinical indication should be clearly documented.
This code represents the neurolytic nerve destruction procedure and does not include the medication or agent itself when separately reportable.
Key Facts About CPT® 64640
- Service type: Interventional pain procedure
- Procedure: Destruction of a peripheral nerve or nerve branch using a neurolytic agent
- Treatment area: Other peripheral nerve or branch
- Purpose: Interrupt nerve signaling to manage pain or other appropriate conditions
- Provider type: Physicians and other qualified healthcare professionals
Common clinical indications:
- Chronic peripheral nerve pain
- Neuralgia
- Neuropathic pain
- Persistent pain following injury or surgery
- Other localized pain conditions appropriate for neurolytic treatment
When to Use CPT® 64640
CPT 64640 is appropriate when:
- A provider performs destruction of an eligible peripheral nerve or nerve branch using a neurolytic agent
- The procedure is medically necessary for the patient's condition
- Conservative or other appropriate treatment approaches have been evaluated when required
- The targeted nerve or nerve branch is documented
Examples:
- Treating chronic localized neuralgia involving a peripheral nerve
- Performing neurolytic treatment for persistent neuropathic pain
- Targeting a peripheral nerve associated with chronic pain after an injury
- Treating a localized pain syndrome when neurolytic nerve destruction is clinically indicated
Documentation Requirements
To support CPT 64640 billing, documentation should include:
- Patient identifiers and date of service
- Diagnosis and clinical indication for the procedure
- Targeted peripheral nerve or nerve branch
- Laterality and anatomical location, when applicable
- Neurolytic agent used
- Dose and administration details
- Procedure technique and guidance method, when applicable
- Patient response and tolerance
- Post-procedure instructions and follow-up plan
- Provider signature and credentials
Detailed documentation helps establish medical necessity and supports accurate procedural billing.
Reimbursement and Coding Considerations
- CPT 64640 is used for destruction of a peripheral nerve or nerve branch using a neurolytic agent
- Documentation should clearly identify the specific nerve or branch treated
- Diagnosis coding should support the medical necessity of the nerve destruction procedure
- The neurolytic agent may be separately reportable when applicable
- Payer policies may include specific requirements regarding conservative treatment, medical necessity, prior authorization, or frequency
- Coding should distinguish neurolytic nerve destruction from other forms of nerve blocks or ablation procedures
Always verify payer-specific interventional pain and nerve procedure billing requirements before submitting claims.
