E899 – Nerve graft - additional cable
OHIP Surgical Assists Code — NEUROLOGICAL SURGICAL PROCEDURES · Schedule of Benefits
This fee is an add-on to N288 and is payable for each additional cable used during a major nerve graft procedure involving a mixed sensory and motor nerve, or a pure motor nerve. Payment Rules: - The fee for the nerve graft (N288) and this add-on includes the harvesting of the nerve(s) required for grafting (). - The main procedure (N288) includes any exploration, decompression, division, excision, and/or neurolysis of the nerves involved (). - All peripheral nerve fee codes, including this one, include any guidance, nerve stimulation, or nerve mapping if performed ().
When to Use
- Use E899 as an add-on to N288 when multiple cable grafts are required to bridge a single nerve gap in a mixed sensory/motor or pure motor nerve.
- Use E899 for each additional cable beyond the first one included in the primary N288 procedure.
Common Pitfalls
- Billing E899 for nerve harvesting; the Schedule of Benefits explicitly states that harvesting is included in the fee for N288 and its add-ons.
- Attempting to bill E899 with codes other than N288, as it is strictly restricted to major nerve grafts under that specific primary code.
- Billing E899 for nerve stimulation or mapping performed during the procedure, as these are considered included in the peripheral nerve fee structure.
Billing Tips
- Ensure the number of units billed for E899 corresponds exactly to the number of additional cables used beyond the initial graft covered by N288.
- Verify that the primary procedure N288 is billed on the same claim, as E899 will be rejected if submitted as a standalone service.
