G243 – Femoral nerve - unilateral
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service code is for a unilateral femoral nerve block. It is listed in the Schedule under the 'NERVE BLOCKS - PERIPHERAL/OTHER INJECTIONS' sub-category of 'Diagnostic and Therapeutic Procedures'. As this procedure is not on the list of delegatable procedures (), it must be rendered personally by the physician.
When to Use
- Use G243 for a standalone unilateral femoral nerve block performed for chronic pain management or diagnostic purposes.
- Use G243 when providing a therapeutic nerve block for acute pain relief in a clinic setting, provided it is not part of a surgical procedure performed by the same physician.
Common Pitfalls
- Billing G243 in conjunction with a surgical procedure performed by the same physician will result in a rejection, as the block is considered inclusive to the surgery fee.
- Attempting to bill G243 alongside G244 for bilateral blocks without appropriate documentation or modifier usage often triggers manual review or audit flags.
Billing Tips
- Ensure the procedure is performed personally, as G243 is explicitly excluded from the list of delegatable procedures under GP63.
