G235 – Supraorbital nerve block
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Supraorbital nerve block is a procedure involving the injection of an anesthetic agent near the supraorbital nerve to provide analgesia. This procedure is listed under Peripheral/Other Injections. When alcohol or other sclerosing solutions are used, the fee can be increased by 50% by billing the add-on code E958.
When to Use
- Use G235 for diagnostic or therapeutic supraorbital nerve blocks to manage acute supraorbital neuralgia or localized forehead pain.
- Use G235 when performing a nerve block for analgesia prior to minor surgical procedures on the forehead, provided it is not part of a global surgical fee.
Common Pitfalls
- Billing G235 alongside a minor procedure code that already includes local anesthesia in its fee schedule definition, which constitutes double-dipping.
- Failing to append E958 when using sclerosing agents, resulting in the loss of the 50% fee increase.
Billing Tips
- Ensure the clinical note clearly specifies the supraorbital nerve as the target to differentiate it from G256 (infraorbital nerve block) or G238 (supratrochlear nerve block).
