Global Periods, Utilization, and Frequency Guidelines - Comprehensive Guide to Peripheral Nerve Block CPT Codes for Pain Management in 2024

• Global Periods: Most peripheral nerve blocks, including CPT 64400, 64405, 64415, 64445, 64447, and 64450, have a 0-day global period, meaning there is no post-operative period included in the payment, and follow-up treatments may be billed separately.
  
• Utilization and Frequency: Peripheral nerve blocks are generally limited to 3-4 injections per site per year, unless there is documented medical necessity for additional treatments. Payers may require justification for more frequent procedures, particularly in chronic pain management.
  
• Imaging Guidance: Imaging guidance using ultrasound (CPT 76942) or fluoroscopy (CPT 77002) is often necessary for accurate and safe nerve block administration. This guidance is usually billed separately but may be bundled depending on payer policies.
  

​Insurance Payer Policies and Clarifications - Comprehensive Guide to Peripheral Nerve Block CPT Codes for Pain Management in 2024

Insurance policies vary by payer, and it's crucial to clarify with each payer their specific coverage guidelines, including:

• Preauthorization Requirements: Some payers require preauthorization for nerve block procedures, particularly if they are repeated or combined with imaging guidance.
• Frequency Limits: Verify the number of injections covered per year, as some payers may impose stricter limits or require additional documentation for frequent treatments.
• Bundling Rules: Ensure you understand each payer’s bundling policies, particularly regarding imaging guidance, to avoid denials and ensure proper reimbursement.
• Documentation Requirements: Thorough documentation is critical, including the patient’s diagnosis, treatment history, and response to previous procedures. This documentation supports the medical necessity of the nerve block and helps prevent claim denials.

By following these guidelines and staying informed about payer-specific policies, healthcare providers can ensure accurate billing, compliance, and optimal reimbursement for peripheral nerve block procedures in 2024 and in 2025.
