E958 – Nerve block with alcohol or sclerosing solution
OHIP Surgical Assists Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use E958 when performing a therapeutic neurolytic block using alcohol for trigeminal neuralgia (G256) to provide long-term pain relief.
- Apply this premium when injecting a sclerosing agent during a diagnostic or therapeutic nerve block (G235 or G238) to achieve permanent nerve ablation.
Common Pitfalls
- Claiming E958 without documenting the specific sclerosing agent or alcohol concentration used in the procedure note, which is required for audit verification.
- Applying E958 to nerve blocks not explicitly listed in the schedule, such as standard local anesthetic blocks, which will result in a rejection.
Billing Tips
- Ensure the primary procedure code (G256, G235, or G238) is billed on the same claim as E958 to trigger the 50% premium calculation correctly.
