E930 – Lateral canthoplasty - when done in conjunction with another procedure
OHIP Surgical Assists Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
Lateral canthoplasty performed in conjunction with another procedure. This code is listed under Orbito-cranial surgery in the Musculoskeletal System section of the Schedule.
When to Use
- Use E930 when performing a lateral canthoplasty to stabilize or reposition the lateral canthus during a primary blepharoplasty or orbital reconstruction procedure.
- Use E930 when the lateral canthoplasty is a secondary, supportive component of a larger oculoplastic surgery, such as correcting lid laxity during an ectropion repair.
Common Pitfalls
- Billing E930 as a stand-alone procedure will result in an automatic rejection, as it is strictly an add-on code requiring a primary surgical code on the same claim.
- Attempting to bill E930 with R399 (or other non-surgical codes) will fail; it must be linked to a primary surgical procedure code from the Schedule.
- Failure to document the specific surgical necessity of the canthoplasty in the operative report often leads to audit recovery, as the procedure must be distinct from the primary surgical approach.
Billing Tips
- Ensure the primary surgical procedure is billed at 100% and E930 is listed as the secondary procedure to avoid incorrect payment calculations.
- If the procedure is performed after hours, apply E409 or E410 to the primary procedure; these premiums will typically apply to the total surgical fee, including the add-on E930.
